On September 6th, a joint cybersecurity advisory was issued by the Cybersecurity and Infrastructure Security Agency (CISA) and the Multi-State Information Sharing and Analysis Center (MS-ISAC) on Vice Society ransomware group that has been active since the middle of 2021 and targets multiple industry sectors including education, healthcare, and government. The threat actor uses double extortion tactics, which victims are threatened for permanently losing encrypted files and leaking stolen data to the public should ransom payment is not made.Why is this Significant?This is significant because alleged Vice Society victims listed on the data leak site includes organizations in education, healthcare, and government sector, which are often exempted by other major ransomware groups. Of the last ten victims (as of September 7, 2022), more than half of them are in education and healthcare sectors.Once the threat actor sets foot into the victim’s network, it laterally moves around the network, exfiltrates valuable information, and deploys ransomware which encrypts files on the compromised machine. The stolen data will be made available to the public, which may cause damage to the reputation of the affected companies.What is Vice Society Ransomware Group?Vice Society is a ransomware group that has been active since at least the middle of 2021 and targets both Windows and Linux systems. What’s unique about this ransomware group is that it deploys third-party ransomware to its victims instead of developing its own ransomware. Such ransomware reportedly includes HelloKitty, FiveHands and Zeppelin ransomware.Below is a typical ransom note left behind by the Vice Society threat actor:As the ransom note states, deployed ransomware encrypts files on the compromised machines. Before the ransomware was pushed by the threat actor, it propagates through the victim’s network using tools such as SystemBC, PowerShell Empire, and Cobalt Strike, and exfiltrate confidential information. The ransom note also provides a few contact email addresses. The threat actor puts additional pressure onto the victim by stating that stolen information will be released to the public if the victim does not email the attacker within seven days. The threat actor operates its own leak site where the threat actor lists victims and releases stolen data. The alleged victims are in many countries around the globe that include but not restricted to Argentina, Australia, Australia, Beirut, Brazil, Canada, Columbia, France, French Guiana, Germany, Greece, Indonesia, India, Italy, Kuwait, Malaysia, Netherland, New Zealand, Poland, Saudi Arabia, Singapore, Spain Sweden, Switzerland Thailand, and United Kingdom, United States.Top page of Vice Society leak siteA reported infection vector used by the Vice Society ransomware group is exploitation of vulnerabilities (CVE-2021-1675 and CVE-2021-34527) that affect Microsoft Windows Print Spooler.
