Chicago Children's Hospital Targeted

 

There’s been a lot written about medical facilities being targeted and compromised over the last five years. The compromises have varied with their penetration into the network and data. The greater the attack’s expanse, the more potential for patient suffering. In late January/early February, Lurie Children’s Hospital system was compromised. This was rather significant with their phones, email, internet service, and medical equipment affected. These systems are in different operational areas in their network, which indicates this was a bit more than the usual attack. The department for penetration in the different systems is notable.

The timeframe for the affected systems was relatively short, at two days. This was still devastating for the staff and patients. The situation was further complicated by the data from the operations that did continue having to be merged into existing data sets.

With hospitals holding so much valuable data, this trend will continue if not grow. There is ample to do with all the patient PII, insurance information, medical history, and other data the hospitals have accumulate every day.

To rebound from this is much more than getting the systems up. The security staff needs to also understand the attack vector and how it was implemented, what systems were breached (not only the ones that were overly noticed), and what data was accessed.

The hospital has much work to do with the incident response. This unfortunately is a prime example of what can happen. Systems need not only be secured but monitored and the tooling reviewed at a regular cadence. Just like the industry is dynamic, so is the tolling. There may be better options or configurations available in the next review cycle.

Energy Sector's Criticality

 

The attacks on the energy sector have been increasing. This is a critical vulnerability for the nation. A successful attack on, for example, the electrical grid would be a disaster from every view. I still remember the time when the grid in the NE region of the US went down in the early 2000s. This was unintentional yet if you lived in the region and was out of power, both consumers and commercial clients, the effect was devastating.

Looking to recent events, there have been attacks that continue to show the vulnerabilities and the effects from these, both financial and human. We can remember the 2021 Colonial Pipeline ransomware attack. The company experienced large financial losses and disrupted their operations. On the attacker’s side, they removed without authorization (i.e., stole) approximately 100GB of data and received $4.4M. A significant portion of this was retrieved, however overall, this had direct negative impacts on the business.

This isn’t a US issue, but global. In 2022, European oil refining ports and storage facilities were targeted. This included 17 terminals. This industry needs the blue team cybersecurity attention. Without this, we will have direct issues affecting our daily lives.

Capital Health Breached

 

No CISO wants to receive the urgent call from the SOC informing them of an issue. This may take the form of a request to make a missed vendor payment by month end or there’s a user that keeps on clicking on the internal phishing campaign emails. The conversation you don’t really want revolves around the defenses being breached. That is clear and immediate project.

Capital Health (NJ) had such an occurrence. LockBit 3.0 claims to have compromised the defenses and liberated over 10M files or over 7TB of confidential medical data. The estimated value of this was $250k. The group did have a bit of their conscious during the attack. They didn’t encrypt the data which quickly would have interfered with the patient care. It’s notable though LockBit 3.0 did not post evidence to document this. While this is the case, there were network outages near the end of December due to a cybersecurity incident. This is not a new event, as too many medical facilities have experienced this on some level.

There have been minimal details as to this which is the standard model. This does highlight the need for this industry to be hyper vigilant and maintain your info cybersecurity toolsets. Periodically when your contract is nearing renewal for the tools, scan the other vendors for their offerings and pricing. Running a PoC and going through the vendor vetting can take time, but it may be well worth it.

Sturdy Memorial Hospital-Not so much

 

Hospitals continue to be targeted at an inappropriate rate over the last five years. Other industries have just as valuable data as the medical field, however, hospitals are in the news at a higher rate. One aspect of this driving the attacks is the criticality of the services. The hospitals require access to the data (e.g., patient charts) and networks to perform the operations, both planned and emergency, procedures, and simply to see patients. The high-level data flow for this is quite simple. In the alternative, the system may be breached, and patient data exfiltrated. The ransom may be demanded as a promise to not distribute or sell this data to other unauthorized parties.

Therefore ransomware, in this circumstance is so potent. Also, the patient data is very important to both parties, the hospital and patient. The hospital must report the breach in most instances. The patient, depending on the data itself, may have the pleasure of monitoring their accounts and credit report for decades.

With the exfiltrated data, the hospital generally has two options. They may or may not pay the ransom to keep the data from being sold to other unauthorized parties. Paying the ransom usually is not recommended. The thought, in this case, after the money is received, they would release it anyway. While this has occurred in a limited number of times over the last few years, this is a detriment to the business model and the malware industry. If the organization is reasonably certain the data will be published anyway, there is absolutely no reason to pay a penny. In this instance Sturdy Memorial Hospital did pay the ransom or fee. The amount was not disclosed. As a result of the breach, the hospital mailed letters to the effected parties. As part of the response, the incident was reported to the FBI.

While the attack vector was not noted, the incident is representative of the reach ransomware has. Dependent on the malware strain, all it can take is one person clicking the wrong link. We still need additional training to limit the potential for this to happen elsewhere.

UF; UH-OH

 

Hospital systems are a treasure trove of data. You know the patient’s name, social security number, address, medical records and identifiers, and other information that can be sold in mass, or divided into section for separate sales. With this area of operations, the data is critical for patient care. This provides leverage for any attacker. If they can remove access to the data and network, through an example of ransomware, the facility would be desperate to get this back online and may be more likely to pay a ransom if there is no access to viable back-ups.

The University of Florida Health System recently had the opportunity to work through this portion of their incident response plan. This did affect the services at the two locations targeted and successfully attached. The two locations of UF Health were Leesburg and The Villages. The attackers were able to shut down their systems. Other than the successful attack itself, it is surprising this is not the first time in recent history this occurred, with the prior occurrence last August.

With two events of this nature occurring within one year, it appears there needs to be additional training for staff or the network needs to be improved.

That was an expensive click

 

Everyone needs or is required to have insurance. This may take the form of auto, health, dental, short- or long-term disability care, or any of the other types of insurance. It seems as though if there is a need, you can find insurance for it. One of the largest commercial insurance carriers in the US is CAN. While being one of the largest insurance carriers in the nation certainly is a success to be applauded, this also has the tendency to put a target on you. After all, when a company is this huge, there is a literal mountain of data to target, and the company certainly has deep pockets to pay a ransom, if they so choose.

Recently CNA had the pleasure of working through an incident much like this. Ironically, CNA sells cyber insurance. In this case, the attackers were able to compromise CNA’s system. Post-breach, they were able to encrypt over 15K of the company’s devices using Phoenix Crypto Locker, a variant of Hades. This variant is engineered to encrypt the files on the compromised machines and demand a ransom for the decrypt key. The group, Evil Corp, was paid the ransom by CNA.

For everyone and organizations that believe “This can’t happen to me!”, yes it can. If CNA who has a vast number of resources and even sells the insurance for this type of incident can be successfully attacked, you certainly can also.

Military vehicle manufacturer hacking

 

The Department of Defense (DoD) business contractors continue to be regularly targeted. These organizations tend to work with secret and top-secret data and information as they develop new systems for use in the military. These could be ground vehicles, jets, ships, and other projects. One contractor, Navistar, was targeted and successfully breached. This was published with their Form 8-K filing with the Securities and Exchange Commission (SEC). The company detected the compromise on May 20, 2021.

With the data involved, the company could not be affected by paralysis by analysis, and immediately went into action to contain the breach, and work towards mitigating the effects from this. After these steps, Navistar began investigating the attack. This was done with security and forensic subject matter experts. They also contacted law enforcement.

As a result, from this, the organization took steps with its infrastructure to strengthen its structure and protect the data from unauthorized parties. Through the attack, the systems continued to be operational. While they aggressively worked to minimize any damage, on May 31 they did receive a communication that data had been exfiltrated during the attack. Considering the updated information, they continue dot investigate the issue and determine the scope of the data involved.

This is another example of what could happen. While you continuously work towards securing the enterprise, there is always a vector available. Arriving at this may be difficult, but it is still there.

Tesla; still targeted

 

Over the years since that fateful day in 2015, there have been many people who have made their name with vehicle hacks. The attacks can be mundane or affect critical systems. Disabling the A/C is by far different than the engine or braking system.

Any vehicle system will have vulnerabilities. The researcher just must find them. One auto manufacturer targeted in the last approximately three years has been Tesla. The vulnerabilities found have required physical access and others have not. In this instance, the vulnerability was found by a Canadian software developer from Quebec (Shankar Gomare). Normally the vulnerabilities are found by cybersecurity researchers. In this case, he was working on his “Voice for Tesla” iOS app early in 2021 and noted the significant vulnerability with Tesla’s Bluetooth key technology. The developer’s app functions much like Amazon’s Alexa providing reminders via voice. The difference with this is the application would not require a specific word or phrase, as Alexa does.

Through developing the application, the developer noted Tesla uses two different forms of Bluetooth sensors in the vehicle. These are Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR). This is used generally for streaming music. The other is Bluetooth Low Energy (BLE). The phone key uses this method. You would use this as a convenience as this use allows the keyholder to unlock the vehicle by being proximate to the vehicle with the connected mobile device (e.g., phone).

As you can figure, the exploit involves Bluetooth. The vehicle’s sensors are coded to detect the strongest Bluetooth signal for connected devices within its range prior to the execute unlock function. This occurs generally with the owner’s mobile device. Here is the issue. The researcher noted the BLE connection did not require authentication to connect to the vehicle. This ends up allowing the researcher to unlock any Tesla by acting as the phone key by forcing the vehicle the request the key from the actual mobile device-by pulling on the door handle.

For this to work, the actual owner’s mobile device would still need to be within 200m-400m for the BLE range. This may seem a bit risky if the owner were walking to their vehicle at the end of the day and saw the person. Where this would work much better would be if the Tesla were parked in the driveway in the evening. Yes, this was patched with an over-the-air (OTA) update.

This is another example of the importance of allowing legitimate cybersecurity researchers to act. The researcher conducted himself appropriately and worked with Tesla for a responsible disclosure. Think through what could have happened if the bad actor had this method and went another route.

Still(water) another medical facility breached

 

As of late, I have been tracking more closely the published breaches and their respective industries. The one industry that appears to be in the lead for breaches now are the medical facilities. Generally being in the lead is a good thing, but not in this instance. One of the latest incidences involved the Stillwater Medical Center. One June 13, 2021, they detected the unusual behavior and incident. This was not script kiddie testing out new software just purchased but affected a few systems. Naturally, as a hospital is attacked, the incident response team immediately took to action and began securing the issue. In addition, after the attack was controlled, they began in earnest to work on the forensic review with the help of a firm specializing in forensic work. Law enforcement was also notified. As this was an active attack, certain systems were placed on an off-line status until the immediate issue was resolved.

This reinforces the complete need for cybersecurity, adequate FTE, and budget. While an organization will not be able to defend against every single type of attack now or in the future, and adequate defense in depth is the best course of action.

Police Departments Continue to be Targeted

 

Police departments are interesting. In business operations, you have business data, customer data, and other points to secure. Police departments do have their operational information but these places also hold a treasure trove of data on the crimes in their area (i.e. evidence). This can be on the persons arrested, the crime, crime scene, and associated data. In addition, the police provide critical service for the area they serve.

Due to these factors, police departments have and continue to be targeted. If simply breaking in isn’t enough of an effort, encrypting or exfiltrating their data can be costly to the department. The Azusa police department recently felt the ransomware sting as the department fell victim to this.

The department announced on May 28, 2021 the issue as being compromised by the ransomware attack. The attackers gained access to the data located in the department’s systems. The department did not pay any ransom or fee. The details have not been provided. From the published information, the ransom was based on releasing information versus encrypting the systems.

The data accessed does appear to be PII, unfortunately. In this case, the attackers appear to have access the social security numbers, driver license numbers, California identification numbers on financial accounts or health insurance. The police department recommended to the parties effected to monitor their credit reports, statements for their accounts, and other information for any unusual or suspicious activity.

This is another example of the far-reaching effects of ransomware. Granted the police department was not affected much, however, the persons permanent and long-term information was. If the data was used for unauthorized purposes, correcting this can be difficult and time consuming, not to mention frustrating.

Here we go again; another ransomware pwnage

 

I remember the days of cameras, purchasing color film or if you wanted to be artsy, using the black & white film. There were several different manufacturers to choose from for the film. With time and technology, there has been a shift from the physical medium to digital. One firm still in the industry is FujiFilm. FujiFilm is probably the best known for its photography equipment. Curiously the company also manufactures a range of medical products. As a large firm, there is ample data gathered everyday from customer interactions, business operations, and other aspects of the business cycle. This provides for a substantial target.

It appears that FujiFilm was targeted and successfully attacked. This was evidenced by the company shutting down a portion of the network and disconnecting this from any external contact. It appears this was de to a ransomware attack.

This continues to be an issue across many industries. With the ease of use for ransomware tools and simply using encryption to accomplish the successful attack, this will likely continue and grow.

 

 

Now I have seen it all

 


There are several companies offering cybersecurity in operation, with yet more popping up. This will probably not slow down with the need for cybersecurity persons increasing daily. Seemingly, the nation has noticed over-night with the pipeline attack that cybersecurity is actually important. These companies have various clients in their respective industries.

One of these recently in the news for all the wrong reasons is located in Atlanta. Vikas Singla, COO of Securolytics, was accused of and indicted on June 8 for attacking the Gwinnett Medical Center. The attack itself took place in 2018 and disrupted the hospital’s phone service, obtaining information from a digitizing device, and disrupting network printing services.

Singla has pleaded not guilty to the 18 charges. There were 17 counts of intentional damage to a protected computer and one count of obtaining information from a protected computer. He was released on a $20k unsecured bond. He is to return to court on June 23, 2021.

The thought is this was done for financial gain. The reason for the attack has not been published, other than this was for financial gain. While this is unknown, this does showcase the need for the review of any insider threat. This is not something people want to act on, as we want to trust our employees, however, this and other instances showcase our need to review this periodically.

Hospitals under attack!

 

One industry that continues to be attacked, and with growing numbers successfully, are hospitals and the medical field. Their data continues to be valuable with the immediate uses and to be dissed and sold several times across the dark web. A method commonly used includes with these attacks is ransomware. The attackers are able to encrypt files, folders, and entire systems and demand a fee, or in addition exfiltrate the data and demand a fee for not publishing this in the public forums. The Sky Lakes Medical Center recently had the opportunity to deal with this issue, arising from their successful attack. Sky Lakes Medical Center is located in Klamath Falls, Oregon.

Data Security Incident

As with any breach, the operations get pretty exciting after one is detected. After all, an unauthorized party is in your system doing who knows what for an indeterminant amount of time. This is especially the case with a healthcare facility due also to a few federal statutes focused on ensuring patient’s data remains private and confidential. In this case, several computer systems were encrypted as part of the attack. The issue was discovered on 10/27/2020. As an initial step, the organization contracted with a cybersecurity firm to investigate the breach.

Data

There was a limited amount of data involved with the breach. The attackers were able to access a limited number of older medical images. Due to the age of these, the effect may be moot. It is fortunate the attackers were not able to access the other areas holding much more current patient data.

Post-Breach

The systems were brought online to continue the facility’s operations. There, also, fortunately, was no evidence any of the accessed data had been misused. To improve the security stance, the organization has taken additional safeguards and added technical security features. At this point, the information published was lacking. For example, the breached systems were not named, if the hospital used recent back-ups or paid the ransom, or if this was accomplished from a phishing email. Regardless of the method, this still shows the importance of employee training and checking your back-ups regularly.

Even Hunger-Relief Groups are not Off-Limits

 

With the economy not doing exceptionally well, people’s wages for the year generally decreasing significantly, and the pandemic continuing at least for the short-term, not-for-profit budgets can be stretched rather thin. As these provide services based on their mission, these may need to be re-evaluated. One form of service desperately needed is food relief and pantries. One of these organizations is Philabundance. Of all the targets available across the vast expanse of the internet, the attackers chose this one.

 

Philabundance is a food relief organization located in the Philadelphia area. This is the region’s largest hunger-relief group. The organization feeds over 100k people per week in the areas it has a presence. With the economic downturn, it shouldn’t be a big surprise this number of people served is almost double last year’s.

 

The attack itself took a widely used, yet simple, attack method. The attackers used phishing as a tool in the summer of 2020 to execute the attack. The organization is constructing a new building. The budget for this is $12M. This new building will house the Philabundance Community Kitchen. The attackers tied into this for the attack. They infiltrated the target system through a phishing campaign. Once in, a rule in the email system was set to block legitimate emails. The attackers were able to then spoof the construction company’s email with a fake invoice for $923,533. The organization paid the fake invoice on July 6, 2020. They discovered the problem when the construction company called for their money on July 24, 2020. After detecting the issue, the investigation began with full force. The effort indicated this was a one-time event. There was no staff information or data accessed. One area the organization specifically noted as not being affected was the online donation platform. There needed to be confidence in the system, so people would continue to donate.

 

Fortunately, the organization was able to cover the debt with its reserves. The hope is the insurance company will assist the organization in replenishing the lost funds. The FBI was contacted and is investigating. The organization hired a cybersecurity subject matter expert to review the incident. Internally, they have begun to update their security system with increased controls and more employee training.

 

Phishing can be tough to defend against. Yes, there are easy instances to detect. These include emails with the misspelled words, grammar not quite making sense, and 85 people being emailed for a late arrival package, all with the same tracking number. More often, the emails encountered have become so much more sophisticated. To maintain the pace with these phishing email advances, the training needs to be updated. With how fast the industry continues to advance, this cannot be overlooked. Of course, the appropriate systems in place to monitor for these.

UK flooring firm pwned

 


Attackers are always looking for new targets to attack. With the vast expanse of the internet, the field is ripe with people and businesses with data or operations to leverage for a fee. A company acknowledged its issue in late November 2020. Headlam Group, a UK flooring group distributor based in Birmingham, experienced a successful attack, acknowledged on November 24. The attackers were able to exfiltrate data as part of the attack. The attackers were able to access the system’s back end, including their email system. The company was able to restore its email system for usage. Fortunately, the company’s customer and supplier information was accessed. The company did not disclose the method the attackers used, however, this was effective. We can learn from their unfortunate issue. All the attackers need is one vulnerability or user to click on one link or picture, while the blue defensive team has to work to patch everywhere possible, monitor the threat feeds for the latest attacks, think through various attacks that could occur, and secure the data at rest.

Of all targets, you chose Sophos

 


You know it’s not going to be a good day when a cybersecurity company is breached. Cybersecurity companies are supposed to be the top tier and subject matter experts of cybersecurity. Since they are selling and marketing their services to other companies, one would infer their stance and defensive posture is without reproach. A recent issue with Sophos recently shown light on this. Sophos is a cybersecurity company, selling many services, located in the UK. The company is well-known in the industry, for good reasons. In mid-November of this year, the company experienced an attack and subsequent breach. The attackers were able to exfiltrate data during the attack, including user names, emails, and contact numbers. Fortunately, per Sophos, only a small number of customers were affected by the issue. This is an example of why we need to maintain vigilance with cybersecurity. This field changes frequently and is not static. The lack of regular updates and monitoring provides for too many viable attacks points to try.

Spartans compromised: MSU breached


Michigan State University (MSU), located in East Lansing, Michigan, is one of the premier institutions in the Midwest. This is a 5,300-acre campus with 563 buildings, with nearly 20,000 cares throughout Michigan used for agricultural and natural resources research and education. In Fall 2019, there were 49,809 students. With such a large number of students, the amount of data generated by the students and administration staff is massive year after year. This data, including the confidential data from the students, provided a significant target for the attackers. This proved to draw these persons to the University’s servers and data.

Attack
Ransomware has been a nasty part of our environment from the last few years. This is a good attack tool due to its low operational overhead and potential large payoff. With this mode, it simply takes the right person in the right department to click on the malware or link. Unfortunately for MSU, the tool was used against the university successfully. The attackers were able to breach the network, access the targeted data, and exfiltrate this. The attackers have demanded a ransom to be paid within a week of the successful attack or they will publish the stolen files. If the university happens not to pay the ransom, the attackers are willing to leak the documents.

Data
The university believes, but is not certain, that the breach and subsequent intrusion was to one (1) isolated unit on the campus. While this is a good thing, the breach itself is still an issue. The files included student, e.g. passport scans, and other private, confidential data, along with university financial documents.

Attackers
The attackers apparently used Netwalker, sometimes referred to as Mailto, ransomware. The ransomware variant was coded to attack the enterprise, in comparison to individual user stations. With this ransomware variant, once the clock runs down to zero, the data and the decrypt key are automatically published.

Mitigation

This is a rather significant issue. There is a prominent university pwned, and their data is being held for ransom. After this was detected, the IT Department took offline the affected systems and servers. This was done to prevent further exposure. MSU’s IT Department notified law enforcement, including the MSU Police Department and Michigan State Police, of the successful attack and threats to begin the investigation.

The latest successful attack is yet another clear indication that we need more cybersecurity training that is relevant. Without this, these attacks will continue to be successful and cause an abundance of harm to the organization, staff, and other parties as part of the collateral damage.

Home Chef’s customer data for sale: Come and get it!



Home Chef, a US-based company, is a meal kit delivery service. If you don’t have time to go to the grocery store and am looking for healthy meals, you can contract with them for meal deliveries to your home. The ingredients show up in a box and you are ready to go! While not an overly complex process, this is still pertinent.

Data Breach
As part of the service, you would pay for the deliveries with your credit card. The company isn’t going to ship your food and hope you pay the bill. The organization does collect certain data from its clients to facilitate this, which is part of the standard operating procedure. Nearly all companies follow this model.  

In this case, there was a successful attack. The compromised customer information included the customer’s name, email address, phone number, and last four digits of the credit card numbers. This would be a much bigger issue; however, the Home Chef does not retain full credit card numbers. In addition, the encrypted passwords and certain account details (e.g. frequency of deliveries and mailing addresses) were also compromised.

Home Chef has not stated how many customers were affected. As a clue to the general number, the attackers responsible for this, Shiny Hunters, claim to be selling approximately 8M records. The price of this database was $2,500. Given the number of records and the data for each record, this is not that bad of a deal. To authenticate, Shiny Hunters also provided a sample.

The attack itself also is a bit of a mystery. The company is not stating this occurred, which is unfortunate. We could use this information as a learning tool. Curiously, Home Chef did not know this had occurred, which is a bit strange as the SIEM should have picked up a bit of unusual activity since, you know, a few records (8M) were compromised and exfiltrated. Home Chef learned of this after they discovered the records were being sold on the dark web. Oops. The InfoSec group probably should have picked up on this. It is also notable, in order to complete this compromise, there would need to be a bit of time involved. It is likely the attackers had access to the systems and data for an extended period as they completed their attack.

Mitigation
Naturally, when this occurs, there is a lot of activity very quickly. The company did state they were taking quick and aggressive actions to investigate the breach.

Follow-Up
Too frequently, companies are not overly aggressive in their timeline to contact law enforcement. Home Chef on the other hand handled this efficiently. And contacted them quickly. The company did email the affected customers, which was done quicker than other firms in like circumstances, which is a good thing. The company is also is recommending the customers change their passwords out of an abundance of caution. Remember, the passwords were encrypted, however, the company may have used weak encryption, which would be a problem.  If these were to be decrypted, there would be a big problem for the customers. This is a good idea also due to the potential for credential stuffing, or the attackers using your password to try access for other accounts. If the users did use the same password across several domains these also should be changed. The customers should also use MFA (multi-factor authentication) moving forward as an additional feature.

Canadian University Breached



Universities have been targeted for well over a decade. These institutions are the steward of their student’s data and information. As this is valuable for the persons attacking the institutions, the attacks tend to be rather frequent. Recently, York University, a university in Canada was successfully attacked.
Attack Timing
When you are planning an attack, you probably don’t want to begin this when the cybersecurity staff is there, monitoring the systems, and ready to address the attack right after it is detected. It would be much better to wait until there is not a full staff present to work to stop the attack.

The attackers took the page from the standardized attack playbook and began their attack on Friday evening. At this point, the staff was headed home for the weekend and not thinking about cybersecurity.

Attack
The attackers were focused on the areas which were holding the data, which they were seeking to exfiltrate. The target, in this case, were the servers and workstations at the University.

Mitigation
While the attack was timed well, the staff was able to detect this quickly. Without their work, the attack effects would have been much worse. The staff was able to directly address this to limit the successful aspects of the attack. The primary method to resolve this was to shut down the University’s computer systems, disconnecting these from the internet.

After the attack, they also contracted with external computer forensic professionals. Their role was to fully research the attack. The attack, per the University, was complex. Regardless of this, the research work will take a fair amount of time to fully complete.

Over the weekend the University was able to restore the Office 365, password change, on-campus student access to the internet, and the University website.

The University also worked on restoring the VPN for HR and Finance, central mail, and the remaining faculty websites.

The University is requiring everyone with the University to reset their passwords. This was directly due to the successful attack.

Additional Information?
At this stage, there has not been much information provided. The forensic examination would require the time needed to fully explore the attack. As much as possible, every facet needs to be detailed and correct.

While this is the standard operating procedure, the University has not provided much information regarding the attack. This should be released so that the industry can learn from this.
One aspect the students did not appreciate was the lack of communication from the attack. The University did not communicate this to the students. The students had to learn of this from statements posted online and on social media. With an attack of this nature, potentially having their data compromised to whoever did the attack, really should have had an official communication.

Lesson one: If you have a breach communicate


Universities are frequently targeted due to the amount of personal, confidential data being held. This is accumulated as part of the application process, along with on-going course attendance. One recent target has been the University of Warwick. The university is located in the Coventry in the UK, and is part of the Russell Group. While the details of the successful attack have not been published, this attack may have been invited in by one of the users. The issue may have all started with a user installing remote viewing software in 2019. At this point, the attackers were able to gain a foothold into the system and pivot into other areas, providing the data and information they sought.

Data
As to be expected, the attack had a focus. In this case, it was the usual data and information. The breach allowed the attackers access to student information. The attackers had also access to the staff and volunteer private information. This would provide the attackers the data needed for various unlawful acts, including taking over someone’s identity, getting credit in the other person’s name, and other fraudulent acts.

Multiple Breaches
In general, one breach is a bad operational defect. This can be devastating to the university, staff, and students in the short- and long-term. This can reach into the full network, or sections, based on the attack and target. If the attacker simply wants to exfiltrate data quickly that is marketable, they may breach the accounting or Human Resource networks. If they want to own the system and possibly extort funds, this is yet another avenue that may be best attacked with ransomware or other malware. In this case, the University was breached several times.

Problematic Factors
Simply stated, the university was breached. Granted, this is a rather unpleasant set of circumstances with potential legal consequences. There appears to be a systemic operational issue though with the breaches. First, there were multiple breaches within the university’s system in 2019. One is bad enough, with the damage that may be done. When you have multiple, the attackers know they are able to get in, get what they want, and exit with ease. If there were to have been an apprehension or concern on the part of the attackers, perhaps they would not have returned so brazenly. For them to return and enter unfettered is indicative of a larger issue.

With these multiple breaches, there is data, intellectual property, and other items possibly removed. There is also the opportunity for them to leave something behind, be it other back doors or malware, to make their life even easier if they would want to enter later. This has a clear impact on the staff and students. From the point in time for the breach, until the notification, the affected persons are blind to the attacker’s using their personal data and information, any researcher’s work product being in unauthorized hands, and generally being open to issues themselves. In this case, the university withheld this information.

One rationale for this was the university did not have the budget and resources to work on this. This, on its own, is an issue. Too many staff do not appreciate the cybersecurity role, and what this actually brings to the organization. Without a robust cybersecurity program in place, there will be issues and many unauthorized persons will have access to your private information. In other words, a reasonably prudent organization would have this in place to protect the data and information which has been given to it to manage and steward.

On another point, prior to the breach, the university was audited by the Information Commissioner’s Office, whose focus is data protection. The report, published in March, noted the chairperson of the university’s data protection privacy group (DPPG) should be replaced with an alternative with more experience. Upon receipt and review, the registrar completely agreed with their findings. Curiously, the registrar and Data Protection Officer are the same people. While the report is after the fact, the indicators had been present for some time and should have been acted on long ago. This report based on the audit was how the staff and students learned of the breaches and that their data had been compromised. Without this report, who knows when the university would have let anyone know of the circumstances. For some reason unbeknownst to many, the registrar joked about the audit, stating it was “tomato colored” and acting dismissive as to the possibility the data was at risk.  
In certain circles, not accomplishing this may be considered negligence.

Apparently, the lack of oversight and resources was to the extent the university may have known they were breached, however, had no idea of what data or systems had been impacted by the attack.

Mitigations
To overcome these problems, the university has created two additional committees to assist with the governance in this area and to provide advice. The university also put a new Chief Information and Digital Officer in place to better the cybersecurity stance.

Lessons
To fully fund the cybersecurity teams and the working group is still vital to operations, and any entity. If you are apathetic as to the network, operations, and any repercussions from a breach and being totally pwned by an unauthorized third party, there is an issue. In these times of budgetary constraints, allocating the resources can be a difficult task. The alternative though tends to be much more expensive financially in the short- and long-term, and provides the opportunity for the organization to be in the news, for all the wrong reasons. There needs to be some form of a balance with the operations. Without this in place, the organization is simply a target waiting to be breached and having to send out the breach notification letters.

There also needs to be the appropriate staff doing the appropriate tasks. There is room for staff with their specific expertise in any organization. When you someone in a role they do not have the experience for, you will have issues. At a senior management level in cybersecurity, there is not the time or the availability of resources to attempt to learn on the job. There will be areas that will be missed in tasks and functions as the person moves through the learning curve. This is not the first time someone has been placed in a management position in cybersecurity without the requisite experience, exemplary of the Peter Principle.

When you have a report publishing of record there are data breaches, as a member of management, you should not act apathetic and as if you are above the findings. The staff in charge of the cybersecurity for a university should take care of the data they are stewarding. They should care enough to ensure their staff and student’s information is not at risk. When an independent third party has to inform you of breaches, something should be done to protect the university, students, and staff other than commenting, as the registrar did, “If I tell you what, I ‘I must kill you.’”

This is a rather serious issue as the breach included personal data and access to the network, unfettered. There is in place during the breach of the GDPR. As time passes, it will be interesting to note if the government actually applies the GDPR or any of the like laws or statutes to the university for the significant error and indifference to the staff and students. The registrar’s response is one of the reasons why there are still numerous breaches.

Anyone affected by this should be wondering why the responsible staff are still present and working at the university, especially the registrar.
