Plan CISA KEV: TrueConf Server flaws under active exploitation
2026-08-22 · BleepingComputer · source ↗ #cisa-kev#video-conferencing#patch
  • Engineer — Plan: TrueConf Server is niche self-hosted comms software, so most teams won’t be exposed, but CISA KEV confirms active exploitation — audit your inventory and if you run TrueConf Server, elevate to Act and apply vendor patches immediately.
  • SOC/IR — Learn: CISA KEV confirms active exploitation but the item provides no IOCs, TTPs, or attack patterns to hunt or detect against; monitor for follow-on threat intel with TrueConf-specific indicators before building detections.

Plan Head Mare hacktivists trojanize TrueConf installers with backdoors
2026-08-09 · BleepingComputer · source ↗ #supply-chain#backdoor#video-conferencing
  • Engineer — Plan: TrueConf is niche in US/global enterprise (primarily Russia/CIS), but if deployed, verify installer hashes against known-good versions and audit endpoints for signs of backdoor execution before using any previously downloaded client packages.
  • SOC/IR — Learn: Head Mare’s installer-replacement supply chain tactic is worth cataloguing for actor awareness, but no IOCs or ATT&CK-mapped behaviors are published yet, leaving no immediate hunt to run.
  • Leader — Learn: This breach illustrates supply chain risk via trojanized software distribution; TrueConf is unlikely to be in most enterprise stacks, but the pattern reinforces vendor software-integrity questions in any video conferencing procurement review.
