A high-severity security flaw in the TrueConf client video conferencing software has been exploited in the wild as a zero-day as part of a campaign targeting government entities in Southeast Asia dubbed TrueChaos. The vulnerability in question is CVE-2026-3502 (CVSS score: 7.8), a lack of integrity check when fetching application update code, allowing an attacker to distribute a tampered update,

Cybersecurity researchers have disclosed a security "blind spot" in Google Cloud's Vertex AI platform that could allow artificial intelligence (AI) agents to be weaponized by an attacker to gain unauthorized access to sensitive data and compromise an organization's cloud environment. According to Palo Alto Networks Unit 42, the issue relates to how the Vertex AI permission model can be misused

Chinese-speaking users are the target of an active campaign that uses typosquatted domains impersonating trusted software brands to deliver a previously undocumented remote access trojan named AtlasCross RAT.

Some weeks are loud. This one was quieter but not in a good way. Long-running operations are finally hitting courtrooms, old attack methods are showing up in new places, and research that stopped being theoretical right around the time defenders stopped paying attention. There's a bit of everything this week. Persistence plays, legal wins, influence ops, and at least one thing that looks boring
