A supply chain attack compromised the Awesome Motive CDN, injecting malicious JavaScript into files served by popular WordPress plugins OptinMonster, TrustPulse, and PushEngage. The injected code targeted logged-in WordPress administrators to create backdoor accounts and install a stealthy backdoor plugin that hides from the admin UI and allows remote code execution. The attack affected sites loading the compromised CDN scripts, exposing potentially millions of WordPress installations. The malicious activity was active briefly in June 2026 before cleanup, but the backdoor presence requires manual detection and remediation.
This is a discussion post on Reddit about a policy model designed to block or alert on access to local sensitive files based on multiple signals such as executable identity, parent process, launch path, access bursts, and cross-store behavior. The post links to an open-source implementation called stealerxhunter, which targets Linux and Windows systems. The author seeks feedback on which signals are strong enough to justify blocking access versus alerting only. There is no direct report of a vulnerability or exploit, but rather a conceptual approach to improving local secret protection.

PromptSnatcher is a malicious data collection operation involving two Chrome browser extensions masquerading as ad blockers with approximately 90,000 combined installs. These extensions intercept full conversation histories, model usage, and subscription tier information from eight major AI platforms, including ChatGPT, Claude, Gemini, and others. The exfiltrated data is sent to operator-controlled servers without clear user notification beyond a vague "Enhanced Protection" consent. The extensions dynamically update their parsing logic from remote command-and-control servers, enabling ongoing targeting without extension updates. Firefox variants falsely declare no data collection permissions while performing equivalent data interception. The operation uses distinct infrastructure for each extension and employs sophisticated API hooking to capture and transmit sensitive AI chat data.
