FBI Warns Active Hive Ransomware Gang Of $100 Million Extortion And Counting

Two weeks in the past, the Biden administration convened the Second Worldwide Anti-Ransomware Summit, warning that ransomware assaults outweigh efforts to mitigate them. Now, the FBI, the Cybersecurity and Infrastructure Safety Company (CISA), and the Division of Well being and Human Companies (HHS) have launched a joint cybersecurity advisory alerting community advocates and organizations to the hazard posed by hive gang ransomware. In response to the advisory, the gang hit greater than 1,300 companies and picked up about $100 million in ransom charges from their victims.

The advisory additionally notes that the Hive doesn’t use a single methodology for preliminary intrusion, as totally different actors within the gang use totally different techniques, methods, and procedures (TTPs). Thus, organizations that handle to handle one or two vulnerabilities identified to be exploited by Hive associates should still be susceptible to assaults by different associates. Hive associates have been discovered to make use of quite a lot of totally different methods to achieve unauthorized entry to victims’ networks, usually beginning with phishing emails that escalate to unauthorized Distant Desktop Protocol (RDP) or digital non-public community (VPN) entry.

The memo additionally warns victims to not contact regulation enforcement or rent ransomware restoration providers, stating that regulation enforcement is not going to permit victims to pay to get better their information and that restoration firms often fail of their negotiations.

The cybersecurity advisor recommends various measures that organizations can implement to cut back the chance of turning into the subsequent Hive Ransomware sufferer. These suggestions embrace making use of safety patches as quickly as potential, and implementing them MFA anti-phishingsustaining offline encrypted backups, and monitoring logs for indicators of compromise (IOCs.) The marketing consultant stresses the significance for healthcare and public well being (HPH) organizations specifically to implement such measures, given the sensitivity of buyer information saved of their techniques.

The Advisor It additionally highlights the next vulnerabilities, which Hive associates have been identified to reap the benefits of, though patches can be found:
