Cisco has patched a bug in Unified Communications Manager that lets an unauthenticated attacker on the network write files to the box and, from there, climb to root. It is tracked as CVE-2026-20230, and proof-of-concept exploit code is already public. Cisco's PSIRT says it has not seen the flaw used in attacks yet. The PoC shortens that runway. The flaw is a server-side request forgery.

A security researcher found a flaw in Anthropic's Claude Code GitHub Action that let an attacker take over vulnerable public repositories running it, with nothing more than a single opened GitHub issue. Because Anthropic's own action repo used the same workflow, a working attack could have pushed malicious code into the action itself and onto the projects downstream that pull it. RyotaK of GMO

Over the past several weeks, the cybersecurity community has been reminded how quickly frontier and agentic AI in defense networks can challenge our assumptions. When Anthropic's Claude Mythos model was made available to a limited set of organizations as a technical preview, it was reported that an unauthorized group claimed that it had gained access within hours. The incident, if true, was

Cybersecurity researchers have flagged a large-scale operation that impersonates open-source and freeware projects to funnel unsuspecting users through a Traffic Distribution System (TDS) and deliver malware families like Remus Stealer, AnimateClipper, and the SessionGate framework. "The sites are well-designed and often look like legitimate project portals at a glance, sometimes referencing

Unknown attackers spent at least five months inside the Outlook mailbox of a senior executive at a major global stock exchange, copying the inbox out in small, repeated batches and routing it through Dropbox and OneDrive so the traffic blended into normal cloud activity. Symantec and Carbon Black's Threat Hunter Team reported the campaign this week. This points to espionage, not a money grab:
