Google Password Manager Attacks Could Let Malware Hijack Passkey
Unit 42 details three attack paths letting Windows malware silently sign into passkey-protected accounts via Chrome's Google Password Manager without user verification.
Palo Alto Networks Unit 42 described three post-compromise attack paths—Pass-ta-key, Silver Pass-ta-key and Golden Pass-ta-key—against Chrome's Google Password Manager cloud authenticator on TPM-equipped Windows systems. The attacks can silently obtain valid authentication assertions, install attacker-controlled user-verification keys, or extract the 32-byte Security Domain Secret used to decrypt synced passkey private keys, enabling reusable access from the attacker's own environment. No CVE was assigned and no exploitation in the wild was reported; demonstrations were validated against Chrome 142 and parts of the architecture are corroborated by Chromium source. GitHub enforced the User Verified flag check, while eBay accepted a test assertion lacking it before fixing its validation gap after disclosure.

Chrome DevTools Technique Enables Authenticated Session Hijacking in Live Windows Browsers
SpecterOps released CDP-Enable-BOF, a Beacon Object File that enables Chrome DevTools Protocol in live Chrome or Edge processes on Windows for session hijacking.
SpecterOps released CDP-Enable-BOF, an x64 Beacon Object File that activates Chrome DevTools Protocol inside running chrome.exe or msedge.exe processes on Windows, exposing cookies, history, saved passwords, and authenticated sessions without administrator rights. It calls Chromium's StartRemoteDebuggingServer on the browser UI thread to stay reliable under CFG, TLS, and CET, and was tested on Chrome 147 and Edge 147. The technique builds on work by DeathFlamingo and Cedric Van Bockhaven; Google had hardened remote debugging in Chrome 136 after attackers used it to steal cookies post-App-Bound Encryption. Defenders can watch Sysmon Event IDs 8 and 10 for injection into browser processes.

Risky Bulletin: Academics find source code overlaps between Geedge and China's Great Firewall
Academics linked Chinese vendor Geedge Networks' Tiangou Secure Gateway source code to one of the Great Firewall's three traffic filtering capabilities.
US researchers presenting at USENIX Security reconstructed Geedge Networks' Tiangou Secure Gateway firmware from over 100,000 leaked files, including Git repositories with commit history, and matched its filtering behavior to sections of China's Great Firewall. They found only 1 of 3 characterized DNS injectors matched Geedge code, noted the system relies on memory-unsafe C components and copied third-party code, and said its bugs could aid future circumvention tools. Geedge also exports censorship tools to Kazakhstan, Ethiopia, Pakistan, and Myanmar. The newsletter additionally rounds up multiple breaches.
