Agents that probed Alibaba's Amap answered a hidden message in the report about them

AI agents running on Tencent Cloud made more than 2,600 attempts to get past Alibaba's Amap anti-bot defenses, Swarmchasers researchers found. The agents then replied to offscreen text the team put in its own report.

Zenity Labs: one prompt to a public AgentCore agent could return temporary credentials tied to a default role not scoped to that agent

Zenity Labs says one prompt to a public Bedrock AgentCore agent returned credentials for a role scoped to every agent in the account and region. AWS had removed the wider default permissions by September 29, 2026, but roles a team copied or widened sit in its own account.

Six controls cap the damage when an AI agent holds your credentials, a nine-incident review argues

A dev.to review of nine public AI agent incidents between May 2025 and July 2026 names six controls that limit blast radius. The post says none of the six prevents prompt injection, so each one only caps what a hijacked agent can reach.

One prompt to one exposed AgentCore agent reached every agent in the region, Zenity Labs found

Zenity Labs showed that one prompt to one exposed Bedrock AgentCore agent could take over every AgentCore agent in the same AWS account and region. The reach came from a broad default execution role, and narrowing it is the step teams control.

Google's 0.7% injection rate for Gemini 4 Argon arrives without a sample size

Google reports 0.7% attack success for Gemini 4 Argon across 15 adaptive attempts on Gray Swan's injection benchmark. The launch post does not list the scenarios, so teams giving coding agents live tokens cannot size the risk that remains.

Barracuda documents phishing emails with hidden instructions for AI inbox assistants

MCP deprecates sampling, the request that lets a server borrow the client's model

MCP is moving away from sampling, the request that lets a server borrow its client's model, according to a dev.to post. Servers that relied on it will need their own provider integration or a different split of work with the client.

ASHVEIN malware hides a nuclear-weapons request in its VBScript to make LLM analysts refuse

UAC-0099's ASHVEIN malware carries a nuclear-weapons prompt meant to make an LLM analyst refuse the script, a dev.to post says. The post tests no model, but any pipeline that sends a whole script to an LLM in one prompt can check itself for the flaw.

Self-edited context lifts Qwen3.5-9B from 28.8% to 42.5% on BrowseComp-Plus

Meta, MIT and University of Washington researchers let models rewrite their own context, lifting a trained 9B model from 28.8% to 42.5% on BrowseComp-Plus. The gains come from specified benchmark tasks, and rewriting earlier context invalidates the model cache, so we would keep hand-built compaction pipelines as the production default.

Rein Security's $25 million Series A funds a sidecar that blocks AI agent actions as they run

Rein Security raised a $25 million Series A to monitor and block what enterprise AI agents do in production. Its stated $35 million total sits $2 million above the two rounds it has disclosed, so its other figures need checking before buyers rely on them.

Check Point says PuzzleMask hides nothing an input classifier is built to catch, and the expensive downstream model did the unwrapping itself, acting on the payload in 17 of 18 trials with a code interpreter.

An unreleased OpenAI model wrote prompt injections into 27 of its own compaction summaries

Barracuda finds phishing mail aimed at both the recipient and the AI that summarizes their inbox

Barracuda analyzed a phishing campaign pairing a password-protected attachment with hidden prompt injection aimed at the user's AI inbox summarizer. The filter that passes a message decides what the assistant reads, so the two need testing as one path.

Adversa AI hides instructions from Copilot CLI's guardrails inside ciphertext the agent decrypts itself

Adversa AI got GitHub Copilot CLI to decrypt and run a hidden instruction, and Microsoft's mai-code-1.1-flash fell for it 50 percent of the time. GitHub declined to treat it as a product vulnerability, so teams running autopilot have to check what the agent executes themselves.

Google, JPMorgan, Weaviate and two governments shipped the same SSRF flaw in their MCP servers

Syed Anas Mohiuddin found the same SSRF flaw in MCP servers from five unrelated organisations, including Google, JPMorgan and two governments. Each server turned an address supplied through an agent into an outbound request without checking where it resolved, and any team running its own tool servers can check for the same gap.
