At the end of August, a malspam message was caught in the quarantine of a mail gateway operated by one of my customers. The message was not especially remarkable – it asked the recipient to review some attached requirements and provide a price quotation for a fiber optic system and appeared to impersonate an employee of a legitimate company.
Dave Chismon, the NCSC’s chief technology officer for architecture, said in a blog post that the imbalance in AI means cyberattacks would likely grow as automated defenses struggle to keep pace.

Security teams have spent decades asking whether an identity has too much access. AI agents raise a harder question: how can we determine which paths an autonomous system can discover, given the access it already has? A person may try several ways to complete a task. A deterministic application follows the flow its developer wrote. But an AI agent is relentless in its pursuit of done. In May
Attackers are exploiting a new flaw in on-premises VeloCloud Orchestrator (VCO), the server that manages the Edge devices in a VeloCloud SD-WAN, Arista said on September 22. The flaw, tracked as CVE-2026-93952, may allow a remote attacker with no login access to privilege internal functions and affect the VCO host. Only orchestrators set up to authenticate their Edges with certificates are
