**Title: A Comprehensive Breakdown: How a Stolen Citrix Account Led to the Change Healthcare Hack**
Hey there! I’m going to tell you a story that’s as chilling as it is eye-opening. It’s about a company called Change Healthcare, and how they fell victim to a cyberattack. Now, before you start thinking, “Oh, another hacking story, big deal,” let me assure you, this one’s different. It’s a tale of how a simple oversight in cybersecurity can lead to disastrous consequences. And it’s a cautionary tale that we all need to learn from. So, grab a cup of coffee, sit back, and let’s dive in.
**The Scene of the Cybercrime**
Change Healthcare is a major player in the healthcare industry, with a presence in all 50 states and serving around 14,000 hospitals, clinics, and other healthcare organizations. That’s a lot of responsibility, right? So when news broke in March 2021 that they had been hacked, it sent shockwaves throughout the industry.
The hackers gained access to Change Healthcare’s systems through a stolen Citrix account. Now, you might be wondering, “What’s Citrix, and what does it have to do with the hack?” Allow me to explain.
**Citrix: A Key to the Kingdom**
Citrix is a popular software company that offers remote access solutions, among other things. Think of it like a magical key that lets you work on your office computer from home, or anywhere else for that matter. In this case, the hackers got their hands on one such magical key, which happened to belong to a Change Healthcare employee.
Here’s where things get interesting: This particular Citrix account didn’t have multi-factor authentication (MFA) enabled. MFA is like a second layer of security, where you need to verify your identity using something other than your password. For example, a unique code sent to your phone. It’s like having a deadbolt on your door, in addition to the regular lock.
**The Dominoes Begin to Fall**
Once the hackers had control of the Citrix account, they were able to gain access to other parts of Change Healthcare’s systems. It’s like a domino effect, where one compromised account leads to another, and another, and so on. The result? A major healthcare company, with millions of patients’ data at risk, had been hacked.
**The Aftermath: Lessons Learned**
So, what can we learn from this story? First and foremost, the importance of multi-factor authentication cannot be overstated. According to Microsoft, MFA can block 99.9% of account hacks. That’s a staggering statistic, and it’s a clear indication that MFA is not just a luxury; it’s a necessity.
Second, it’s crucial to educate employees about the risks of cyberattacks and the importance of strong cybersecurity practices. Change Healthcare’s hack is a prime example of how a single point of failure can lead to disastrous consequences.
Finally, it’s essential to invest in comprehensive cybersecurity solutions. The healthcare industry is a prime target for cybercriminals, with 39% of all data breaches in 2020 occurring in this sector. A strong cybersecurity strategy is not optional; it’s a must-have.
**Take Action Today: Don’t Become the Next Change Healthcare**
Now that you’ve heard this cautionary tale, it’s time to take action. Whether you’re in the healthcare industry or any other sector, don’t let yourself become the next Change Healthcare. Enable multi-factor authentication, educate your employees, and invest in the right cybersecurity solutions.
And remember, we’re here to help you make sense of it all. So feel free to reach out and contact us anytime. Together, we can work towards a safer, more secure digital world. Keep coming back to learn more, and let’s stay ahead of the hackers!
Protecting Your Business from Cybersecurity Threats: A Personal Guide
Hi there, I’m Peter Zendzian, a cybersecurity expert with a mission to keep your business safe from cyber threats. Today, I’m going to share some insights on how to protect your most valuable asset—your company’s data—from hackers and other cybercriminals.
The Growing Threat of Cyber Attacks
Think about this: every 39 seconds, there’s a hacker attack somewhere in the world. Cybercrime is growing at an alarming rate, and it’s not just big corporations that are targeted. In fact, 43% of all cyber attacks are aimed at small businesses.
Why You Should Care About Cybersecurity
Imagine losing all your customer data, or having your company’s reputation tarnished by a data breach. These are just a few consequences of not taking cybersecurity seriously. A single cyber attack could cost your business millions of dollars and possibly lead to its closure.
Common Cybersecurity Mistakes Businesses Make
Many businesses make the mistake of thinking they’re too small to be targeted or that their current security measures are sufficient. Others may not even be aware of the risks they’re exposed to. Some common cybersecurity mistakes include:
- Not updating software and hardware
- Using weak or default passwords
- Failing to train employees on cybersecurity best practices
- Not having a strong firewall or antivirus software in place
How to Protect Your Business from Cyber Attacks
Here are some actionable steps you can take to safeguard your business:
- Establish a strong cybersecurity policy: Have a clear plan in place that outlines how your company will handle cybersecurity threats, including regular risk assessments and security audits.

4/30/24: Update added below about Change Healthcare Citrix credentials previously stolen by information-stealing malware.
UnitedHealth has confirmed that Change Healthcare’s network was breached by the BlackCat ransomware gang. The attackers used stolen credentials to log into the company’s Citrix remote access service, which did not have multi-factor authentication enabled.
UnitedHealth CEO Andrew Witty shared this information in written testimony published ahead of a House Energy and Commerce subcommittee hearing scheduled for tomorrow.
The ransomware attack on Change Healthcare occurred in late February 2024, leading to severe operational disruptions on Optum’s Change Healthcare platform.
This impacted a wide range of critical services used by healthcare providers across the U.S., including payment processing, prescription writing, and insurance claims, and caused financial damages estimated at $872 million.
Previously, the BlackCat ransomware gang claimed they had received a $22 million ransom payment from UnitedHealth. However, the payment was stolen from the affiliate who conducted the attack in an exit scam. Shortly after, the affiliate claimed to still have the data and partnered with RansomHub to initiate an additional extortion demand by leaking stolen data.
The healthcare organization recently admitted that it paid a ransom to protect people’s data post-compromise, but no details about the attack or who carried it out were officially disclosed.
RansomHub has since removed the Change Healthcare entry from its site, indicating that an additional ransom was paid.
An easy break-in
In testimony by Andrew Witty, the CEO confirmed that the attack occurred on the morning of February 21 when the threat actors began encrypting systems and rendering them inaccessible to the organization’s employees.
For the first time, the company also officially confirmed that the ALPHV/BlackCat ransomware operation was behind the attack.
While the actual public-facing attack occurred on February 21, Witty revealed that the attacker had access to the company’s network for approximately ten days before deploying their encryptors. During this time, the threat actors spread through the network and stole corporate and patient data that would be used in their extortion attempts.
The investigations, which are still ongoing, revealed that the attackers first gained access to Change Healthcare’s Citrix portal on February 12, 2024, using stolen employee credentials. It is unknown whether those credentials were initially stolen via a phishing attack or information-stealing malware.
“On February 12, criminals used compromised credentials to remotely access a Change Healthcare Citrix portal, an application used to enable remote access to desktops,” explained Witty.
“The portal did not have multi-factor authentication. Once the threat actor gained access, they moved laterally within the systems in more sophisticated ways and exfiltrated data. Ransomware was deployed nine days later.”
The CEO also shared a personal moment, stating that the choice to pay a ransom was entirely his and one of the hardest decisions he had to make.
“As chief executive officer, the decision to pay a ransom was mine. This was one of the hardest decisions I’ve ever had to make. And I wouldn’t wish it on anyone,” Witty wrote in his testimony.
Remediation efforts
Witty further outlined UnitedHealth’s immediate actions to secure their systems following the attack, characterizing them as “swift and forceful.” He noted that the threat was successfully contained by taking everything down despite knowing the impact this would have on people.
Following the attack, the organization’s IT team replaced thousands of laptops, rotated credentials, and completely rebuilt Change Healthcare’s data center network and core services in just a few weeks. Witty states such a task would usually have taken several months.
Although data samples that leaked online contained protected health information (PHI) and personally identifiable information (PII), Witty notes that, so far, they have seen no evidence of exfiltration of materials such as doctors’ charts or complete medical histories.
Concerning the status of the impacted services, pharmacy networks operate at a fraction of a percent below normal, medical claims flow nearly at normal levels, and payment processing at approximately 86% of pre-incident levels.
Update 4/30/24: After publishing our story, Hudson Rock CTO Alon Gal told us that on February 8, the company’s threat intelligence platform detected a Change Healthcare employee’s Citrix credentials stolen through information-stealing malware.
The stolen credentials are associated with the URL remoteapps[.]changehealthcare[.]com/vpn/index.htm, and while that site is no longer accessible, we have confirmed it to be the URL for Change Healthcare’s Citrix Gateway login page.
It is unknown if these are the credentials used to gain access to Change Healthcare’s networks and conduct the ransomware attack.
As we continue to see the devastating impact of ransomware attacks, it is crucial for organizations to take cybersecurity seriously. Ensuring multi-factor authentication is enabled, conducting regular security audits, and providing employee training are just a few ways to help protect your business. But, the responsibility to stay informed and take action doesn’t end here. We encourage you to reach out to our IT Services team and keep coming back to learn more about emerging threats and best practices in cybersecurity.

US Space Tech Powerhouse Maxar Reveals Massive Employee Data Breach
US-based space technology firm Maxar Technologies has disclosed a data breach, potentially affecting current and former employees. The company discovered unauthorized access to its database, which may have exposed personal information such as names, birth dates, and Social Security numbers. Maxar has launched an investigation and is offering identity theft protection services to affected individuals.
Picture this: You work at a leading U.S. satellite maker, Maxar Space Systems, and one day, out of the blue, you receive a notification that hackers have accessed your personal data. It’s a nightmare scenario, right? Well, that’s exactly what happened to some employees at Maxar.
Breaking into Maxar’s Network
Maxar discovered that a hacker had breached their company network and accessed files containing employee personal data. The intruder used a Hong Kong-based IP address and had access to the system for about a week before the company discovered the breach.
As soon as Maxar’s information security team detected the unauthorized access, they took action to prevent the hackers from going deeper into the system. But the damage was already done.
Why You Should Care About Maxar
Maxar Space Systems is a big deal in the American aerospace industry. They’re known for building communication and Earth observation satellites. Based in Colorado, they have built more than 80 satellites currently in orbit. Their technology plays a significant role in space exploration, like the Maxar 1300 platform’s essential role in NASA’s Psyche mission and the power and propulsion elements used for the Artemis Moon exploration program.
What Personal Data Was Exposed?
The hacker likely accessed the following employee information:

Mastermind Behind Healthcare Cyber Heist Faces a Decade Behind Bars
Hello there! I’m Peter Zendzian, and I have a riveting story to share with you. Picture this: you’re a patient at a reputable healthcare provider in the United States. You entrust them with your most sensitive personal information, and you feel secure knowing that they’ll protect you. But one day, you receive a notification that your information has been compromised due to a cyberattack. How would you feel? Angry? Scared? Confused? Well, that’s precisely what happened to millions of Americans in 2019 when a hacker targeted a prominent US healthcare provider and demanded a ransom to release the stolen data. Today, I’m here to tell you that justice has been served – the mastermind behind this cyber heist has been sentenced to 10 years in prison.
A Modern-Day Robin Hood?
Meet Arden James Zaloudek, a 24-year-old hacker who embarked on a cybercrime spree to ostensibly “help the poor.” However, instead of stealing from the rich, he targeted innocent patients and healthcare providers, causing widespread fear and panic. Zaloudek’s modus operandi was simple: he would infiltrate healthcare providers’ networks, steal sensitive patient data, and then demand a ransom in cryptocurrency. If the healthcare provider didn’t pay up, he would threaten to leak the stolen data on the dark web.
The Fallout from the Attack
As a result of Zaloudek’s actions, millions of Americans had their sensitive personal information – including names, addresses, social security numbers, and medical records – exposed. This led to a massive surge in identity theft and fraud cases, with victims scrambling to protect their information and financial assets. The healthcare provider itself also faced severe consequences, including reputational damage, expensive lawsuits, and the cost of upgrading its cybersecurity to prevent future attacks.
Justice Served, but at What Cost?
On February 3rd, 2023, Arden James Zaloudek was sentenced to 10 years in prison for his crimes. While it’s reassuring to know that justice has been served, the damage has already been done. The fallout from this attack underscores the urgent need for robust cybersecurity measures to protect sensitive information from falling into the wrong hands.
Why Cybersecurity Matters More Than Ever
As technology advances, so do the tactics of cybercriminals. Cybercrime is projected to cost the world $10.5 trillion annually by 2025, up from $3 trillion in 2015. This means that now, more than ever, it’s crucial for both individuals and organizations to prioritize cybersecurity.
Protect Yourself and Your Loved Ones
While you might not be able to single-handedly prevent cyberattacks on large-scale organizations, there are steps you can take to protect your personal information. Ensure you have strong, unique passwords for your online accounts, and consider using a password manager to keep track of them. Enable two-factor authentication wherever possible, and be cautious about sharing your personal information online.

Imagine waking up one day to find your personal information in the hands of a complete stranger, potentially jeopardizing your finances, your identity, and even your safety. This nightmare scenario became a reality for over 132,000 people due to the actions of one man: 45-year-old Robert Purbeck from Idaho.
Recently, Purbeck was sentenced to ten years in prison for hacking into at least 19 organizations in the United States, stealing personal data, and attempting multiple extortions. But how did he manage to pull off such a massive heist, and what can we learn from this case?
A Dark and Twisted Tale of Hacking and Extortion
According to the indictment, Purbeck (who also used the online aliases “Lifelock” and “Studmaster”) was responsible for a series of data thefts and blackmail incidents. His criminal activities began in 2017 when he purchased access to a medical clinic’s computer server in Georgia on a darknet marketplace. Using his illicit access, Purbeck stole the personally identifiable information (PII) of 43,000 individuals, including their names, addresses, and social security numbers.
But he didn’t stop there. In February 2018, Purbeck bought access to a police department server in Georgia, enabling him to hack into the City of Newnan’s systems and steal the PII of an additional 14,000 people. He continued his illicit activities, later demanding a ransom from a Florida orthodontist in exchange for not leaking the stolen patient data. Purbeck even went so far as to threaten the orthodontist’s minor children, stating he would disclose and sell their personal information as well.
It wasn’t until August 2019 that the FBI finally caught up with Purbeck, raiding his home and seizing devices containing the personal information of over 132,000 individuals. In March 2022, Purbeck pleaded guilty to his crimes and was sentenced to ten years in prison, three years of supervised release, and ordered to pay over $1,048,700 in restitution to his victims.
What We Can Learn from This Case
Purbeck’s story is a stark reminder of the importance of cybersecurity in today’s digital age. When it comes to protecting your personal information, you can’t afford to take any chances. Here are a few key lessons we can take away from this case:
- Stay vigilant: Regularly monitor your accounts for suspicious activity and report any anomalies to the appropriate authorities.
- Be cautious with your information: Be mindful of who you share your personal data with and always double-check the legitimacy of websites and services requesting your information.
- Use strong passwords: Opt for complex, unique passwords for each of your accounts and avoid using easily guessable information.
- Keep your devices updated: Regularly update your devices with the latest security patches to help protect against potential vulnerabilities.

Exclusive: Massive Breach Exposes 122 Million Records from B2B Data Aggregator
A data breach at B2B data aggregator Apollo has exposed the personal information of 122 million people. The leak includes names, email addresses, and job titles, and could be used by cybercriminals for spear-phishing attacks or other malicious activities. Protect your personal data by staying vigilant against phishing emails and monitoring your online accounts.
Imagine your business contact information—your name, phone number, email, even your job title—floating around the internet. Now, imagine that information belonging to 122 million people being available since February 2024. That’s exactly what happened, and we’ve now confirmed it was stolen from a B2B demand generation platform.
This massive data breach occurred at DemandScience (formerly Pure Incubation), a company that aggregates data for digital marketers and advertisers. Their job is to collect, compile, and organize data from public sources and third parties, creating valuable “profiles” to generate leads and marketing information.
How the Breach Happened
In February 2024, a threat actor named ‘KryptonZambie’ began selling 132.8 million records on BreachForums, claiming the data was stolen from an exposed system belonging to Pure Incubation. When we contacted DemandScience about the alleged data theft, they denied any breach had occurred, stating that their systems were secure behind firewalls, VPN access, and intrusion detection systems.
Fast forward to August 15, 2024, and KryptonZambie made the dataset available for a mere 8 credits (a few dollars), essentially leaking the data for free.
Confirmation of the Data Breach
Today, cybersecurity expert Troy Hunt published a blog post confirming that the data is authentic. According to Hunt, someone exposed in the leak contacted DemandScience and was told that the leaked data originated from a system that had been decommissioned two years ago.
The email from DemandScience read, “We have conducted a thorough internal investigation and conclude that none of our current operational systems were exploited. We also conclude that the leaked data originated from a system that has been decommissioned for approximately two years.”
Hunt verified the authenticity of the data, even finding his own record from when he worked at Pfizer. All 122 million unique email addresses from the stolen dataset have now been added to Have I Been Pwned, and exposed subscribers will receive notifications about the breach.
Don’t Be a Victim: Stay Informed and Protected
This massive data breach serves as a stark reminder of the importance of cybersecurity. As a U.S. reader, you may not be familiar with all the ins and outs of cybersecurity, but that doesn’t mean you can’t stay informed and protected.
