BragJack is a security research discovery demonstrating how a single browser extension can hijack internal browser agents across five Chromium-based browsers: Chrome, Comet, Edge, Opera Neon, and Claude in Chrome. The attack leverages the declarativeNetRequest (DNR) API to weaken security headers and redirect JavaScript resources, enabling code execution within privileged browser contexts. This allows access to sensitive capabilities such as local file access, browsing history, camera and microphone, and screenshots without user interaction. The research resulted in two CVEs and $20,000 in bounty rewards from major vendors. The vulnerabilities primarily exploit weaknesses in how these browsers handle network requests and security policies within embedded web views. No patch or remediation status is provided in the source data.
The KREMLIN toolkit is a Brazilian banking malware operation active since May 2025, targeting Brazilian financial institutions via malicious Chrome browser extensions. It manipulates Chromium's integrity checks by forging Secure Preferences and HMACs to evade detection. The malware intercepts credentials, session tokens, and sensitive banking data through keylogging and request interception. The operation uses Ethereum smart contracts for dynamic command and control configuration and has evolved through multiple campaigns delivering different remote access trojans. Over 1,500 infections have been temporarily disrupted, with the vast majority of victims located in Brazil.
