Software solutions provider Young Consulting has informed over 950,000 individuals that their personal information was compromised in a significant data breach earlier this year. The breach, which occurred in April, exposed sensitive data belonging to clients, including the health insurer Blue Shield of California, among other covered entities.
The incident came to light on April 13, when Young Consulting detected "technical difficulties" within its network environment. In response, the company promptly took several systems offline to contain the issue and initiated an investigation with the help of a cybersecurity forensics firm.
"We immediately took certain systems offline to contain the incident and launched an investigation, with the assistance of a cybersecurity forensics firm, to determine the nature and scope of the event," Young Consulting explained in a notification on its website.
The investigation revealed that attackers had accessed Young Consulting's network between April 10 and April 13, during which they copied files containing personal information. The stolen data includes names, dates of birth, Social Security numbers, insurance policy and claim information, prescriptions, and provider names. The breach specifically affected health plan members’ information from Blue Shield of California, which publicly disclosed the incident after being notified by Young Consulting.
Young Consulting has begun notifying 954,177 affected individuals and is offering one year of free credit monitoring services to those impacted. The company has not disclosed additional details about the affected entities or the specific nature of the cyberattack.
However, in early May, the BlackSuit ransomware group claimed responsibility for the attack by listing Young Consulting on its Tor-based leaks site. The group alleged the theft of various types of data, including business, employee, and financial information, which they have since made available for download. This suggests that Young Consulting did not meet the group's demands, leading to the public release of the stolen data.
Expert Insights on the Evolving Threat Landscape
Andrew Costis, Engineering Manager of the Adversary Research Team at AttackIQ, commented on the breach: "Nearly 1 million individuals were notified by Young Consulting that their personal information was compromised during an April cyberattack. Young Consulting, a software solutions provider for 'stop loss' insurance, was subsequently listed on the BlackSuit ransomware group’s leak site in May. The breached data includes personally identifiable information such as Social Security numbers, names, dates of birth, and insurance policy/claim details."
Costis also highlighted the evolving nature of ransomware threats, noting, "Yesterday, the FBI and CISA issued an update to the joint Cybersecurity advisory on BlackSuit ransomware. BlackSuit is the evolution of ransomware previously known as Royal ransomware. While there are coding similarities between Royal and BlackSuit, BlackSuit has exhibited improved capabilities."
He emphasized the importance of proactive cybersecurity measures in light of these developments: "While we continue to see an increase in threats not only from BlackSuit but on third-party providers, it's important for organizations to test their systems against these threats and adopt more of a proactive security stance. Reactive cybersecurity is no longer sufficient. By testing against the known tactics, techniques, and procedures (TTPs) of BlackSuit, and emulating these attacks, organizations can gain valuable insights into their systems' responses, maximizing efficiency and pinpointing any vulnerabilities."
A Call for Heightened Vigilance
The breach at Young Consulting underscores the growing threat posed by sophisticated ransomware groups like BlackSuit, which have evolved from previous variants such as Royal ransomware. As cyberattacks become increasingly targeted and damaging, organizations are being urged to adopt more proactive security measures and to regularly test their defenses against known threats.
For those affected by the breach, the incident serves as a stark reminder of the importance of safeguarding personal information and the potential risks associated with third-party data handlers. With cybercrime showing no signs of slowing down, companies and individuals alike must remain vigilant and prepared to respond to evolving digital threats.
