New pro-Ukraine hacker group targets Russian companies with custom ransomware
VantaCore, a pro-Ukraine hacker group, has targeted at least seven Russian companies with custom ransomware, according to a report from cybersecurity firm F6. The group's operations underscore the expansion of politically motivated cyber activity targeting Russian entities.
Why it matters: Organizations operating in or connected to Russia face direct targeting by state-aligned threat actors; practitioners should assess exposure to this group's custom malware and monitor for indicators of compromise from recent victims.
