Several organizations that were impacted by the recently disclosed breach at enterprise firewall company Accellion had their data stolen and subsequently used as leverage in extortion attempts.
New analysis of the incident by Mandiant found that data belonging to multiple companies in the United States, Canada, the Netherlands, and Singapore has so far been released via a Dark Web site associated with a known Russia-based threat actor called FIN1 that has recently been observed operating a ransomware strain called CLOP. Victims include organizations in a wide range of sectors, Mandiant said.
Accellion on January 12 briefly disclosed that attackers had exploited a zero-day vulnerability in its File Transfer Appliance (FTA), a near-obsolete 20-year-old technology that enterprise organizations around the world have been using for years to transfer large files. The vendor said it had learned of the breach in mid-December and issued a patch for it in less than 72-hours. A subsequent—and similarly brief—update on Feb 1, suggested that the attackers had exploited not one, but several vulnerabilities in FTA, all of which the company said it had closed. Accellion urged FTA customers to switch to the company's newer Kiteworks technology as soon as possible.
Accellion itself has downplayed the scope of the incident and initially had described the breach as impacting less than 50 customers worldwide. However, a quickly growing list of breach disclosures by customers of FTA around the world suggests the actual number of victims could be higher.
