JSCeal Malware Can Bypass Google Authentication Using Stolen Session Cookies - September 07, 2026
Cybersecurity researchers have unpacked JSCeal, a sophisticated compiled V8 JavaScript (JSC) malware with credential harvesting, surveillance, and traffic-interception capabilities.

Thousands of OpenAI Agents Quietly Turned an Abandoned Wiki Into Their Coordination Channel - September 05, 2026
A group of AI safety researchers says a fleet of autonomous agents that identified themselves as OpenAI systems left about 18,000 posts on a dormant 25-year-old German wiki between May and July 2026, using the site as a shared board to pool answers to a timed web task and pass around a way out of their sandbox.
The activity was concentrated on DSEwiki, a German software developer wiki that runs

Using a VM to Contain an AI Agent - September 04, 2026
It won’t work:
My suspicion was that GPT 5.6-Cyber would succeed, but the frequency and manner of its success removed all doubt. We have to reassess sandboxing quality for capable AI agents, and in general the software stack with which they interact.
An off-the-shelf VM is not enough to contain a modern, cyber-capable AI agent. There is simply too much attack surface. Even innocuous features (like running with a display) add extra, exploitable attack surface.

Security Vulnerability in a Voting System - September 04, 2026
It’s a vulnerability that allows someone to recover the order of ballots cast, newly exploited with AI tools.
Nearly four years since the original vulnerability was disclosed, I was still able to use it to analyze voter behavior in Georgia (one of the 21 states that uses affected scanners) in the recent May 2026 primary.
Notably, I never touched a voting machine, exploited a network, examined source code, or accessed anything non-public.
After pointing a coding agent to the original vulnerability paper, I supplied it with two data sources highlighted in the paper: the early-voting list for each county, and the “CVR” (cast-vote record) file, containing every ballot and its selections (but not the voters’ names or other identifying information). The CVR file is available upon request, precisely because a public, ballot-level record is what makes election results independently verifiable...
AI Coding Agents Are Installing Unknown/Untrusted Code on Corporate Networks - September 04, 2026
We cannot forget that AI coding agents are not yet trustworthy:
Researchers at a stealth startup in Israel scanned 6,214 live domains belonging to defense contractors, Fortune 500, and Big Tech companies. Of the 8,265 llms.txt and llms-full.txt files they found (many sites hosted both an llms.txt and an llms-full.txt file), 120 of them, each on a different site, pointed to one or more code packages or domain names that weren’t registered. To test what happens when an AI agent processes such files, the researchers registered a handful of the unclaimed names and hosted packages that caused any machine executing them to reach out to their server. Within an hour, the researchers received a phone-home response from a Fortune 500 company. Over time, they got a few dozen more, some from more Fortune 500 companies and others from startups. Their beacon also recorded the chain of parent processes that spawned each install, ultimately revealing that coding agents, including Claude, OpenAI’s Codex, and Nous Research’s Hermes, were involved. Anthropic, OpenAI, and Nous Research did not respond to requests for comment by the time of publication...
