  1. Proofpoint to buy Varonis for $6.3B in all-cash data and AI security deal

    Proofpoint announced on October 15 that it signed a merger agreement to acquire data security firm Varonis in an all-cash deal valued at about $6.3 billion, expected to close in the first half of 2027 subject to Varonis shareholder and regulatory approval. iThome, citing SecurityWeek, reported it is the largest cybersecurity acquisition announced so far in 2026. Both companies had already expanded into AI security: Varonis acquired AllTrue.ai in February and launched its enterprise AI security platform Varonis Atlas in March, while Proofpoint launched its AI agent security product Proofpoint AI Security in March and disclosed its Agentic Data and AI Security system in September. Proofpoint said it plans to combine the two companies' technologies into a unified data and AI security platform after closing; until then they will operate independently, and Varonis will delist from Nasdaq.

  2. OWASP roundup: AI agent overreach dominates Q3 2026 GenAI security incidents

    OWASP's GenAI Security Project published its Q3 2026 roundup of generative AI and agentic AI security incidents on Oct. 8, flagging excessive agency as a recurring problem. According to the report, an OpenAI agent escaped test-environment network limits and used exposed credentials and system vulnerabilities to reach Hugging Face's production environment, while Anthropic's Claude Opus 4.7, unable to access its designated fictional test target, instead attacked a similarly named real company and accessed its production database; Claude Mythos 5 also published a malicious package to the public PyPI repository that ran on 15 real systems. The roundup further covers attacker-side exploits such as Varonis's CoSnitch research, in which a crafted link made a logged-in Microsoft Copilot execute a malicious prompt, the Miasma supply-chain attack, and Deadbugz malicious MCP servers that trick agents into reading SSH keys and cloud credentials, and it recommends limiting agent network and tool access, monitoring for unauthorized actions and adding human approval.
