AgentBaiting: How Fake AI Skills Deliver Malware at Scale
Island security researchers uncovered the FakeGit campaign, which used roughly 7,600 malicious GitHub repositories—over 800 posing as AI Skills or MCP servers—to deliver SmartLoader malware that installs the StealC information stealer. The campaign introduces a technique called AgentBaiting, in which AI agents such as Claude Code, Gemini, and ChatGPT autonomously discover the attacker repositories, treat the malicious README as legitimate documentation, and pass installation instructions to users; the operation recorded over 14 million downloads.supply-chain · tool-abuse · malware-delivery · agentbaiting

The Week of Sandbox Escapes
Pillar Security researchers demonstrated seven sandbox-escape techniques against four AI coding agents — Cursor, OpenAI's Codex, Google's Gemini CLI and Antigravity — where a sandboxed agent writes workspace files that trusted tools running outside the sandbox (Python extensions, Git integrations, hook engines, Docker daemons) later execute. Prompt injection planted in a README, issue, dependency, or diff triggers local command execution on the developer's machine; one Cursor flaw is tracked as CVE-2026-48124 and fixed in version 3.0.0, with most issues patched and vendor-acknowledged.

Fake Bug Report Hijacks AI Coding Agents at Scale
Tenet Security demonstrated "agentjacking," an indirect prompt-injection technique in which an attacker plants a single fake error report in a public bug-tracking service (Sentry) that hijacks AI coding agents into running attacker-controlled code on a developer's machine. In controlled testing, widely used assistants including Claude Code, Cursor, and Codex retrieved the poisoned error data and, in many cases, executed the code, opening a path to theft of cloud credentials, AWS keys, GitHub tokens, SSH keys, and CI/CD secrets.

State of MCP Security 2026 v2
Canopii's "State of MCP Security 2026" report scanned more than 11,000 published Model Context Protocol servers and found 830 graded D or F, 232 with confirmed dangerous code sinks (eval, shell injection, unsafe deserialization) that can turn prompt injection into host code execution, 184 versions that silently altered tool definitions after publication ("rug pulls"), 1,617 servers shipping dependencies with known vulnerabilities, 260 running install-time scripts, and 7 confirmed typosquats. Popular servers with 1,000+ GitHub stars were over 5x more likely to be high-risk. Details →First reported wiz.io
Amazon Q VS Extension Flaw Leads to Cloud Credential Theft
A vulnerability in the Amazon Q Visual Studio extension could let adversaries plant a malicious repository that executes arbitrary code and steals cloud credentials, highlighting growing MCP-related risk. Details →How the wire is made
