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

AI browser guardrail bypass exposes a new data theft path
LayerX Security describes a "BioShocking" attack that games an AI browser into violating its guardrails by establishing a false reality, enabling data theft, code copying, and system command execution. The attack exploits the browser-mediated trust boundary, using indirect or staged instructions embedded in webpage context that pass prompt filters yet still steer the model into malicious enterprise actions inside an authenticated session.

EchoGram and guardrail bypass: are AI defenses keeping up?
HiddenLayer research dubbed EchoGram demonstrates that carefully chosen token sequences can flip verdicts in LLM guardrail models, causing harmful prompts to be marked safe or benign prompts to trigger false alarms. The NHIMG editorial summarizes the finding and its implications for organizations relying on probabilistic AI safety layers to protect deployed LLMs and agents. Details →First reported huntress.com
New BioShocking attack manipulates AI browser into data theft
A new prompt injection attack dubbed 'BioShocking' reportedly tricks AI-powered browsers into treating risky real-world actions as part of a fictional scenario, bypassing safety guardrails and enabling data theft. Details →First reported · updated · 2 reports adversa.ai
GuardFall: a universal shell injection vulnerability in open-source AI agents
Adversa AI research describes GuardFall, a bypass of AI coding agents' safety filters using decades-old shell injection tricks to execute dangerous commands. The bypass reportedly worked against 10 of 11 tested popular open-source coding and computer-use agents, with only 'Continue' being resistant. Details →First reported thehackernews.com
New BioShocking Attack Tricks AI Browsers Into Leaking User Credentials
LayerX disclosed a technique called BioShocking that convinces AI browsers they are playing a game, tricking them into copying a user's credentials and sending them to an attacker. Six AI browsers and assistants were affected, including OpenAI's ChatGPT Atlas, Perplexity's Comet, and Anthropic's Claude browser extension. Details →How the wire is made
