Cyber Digest
A daily roundup of key cybersecurity developments across sectors
Executive Summary
A major joint international advisory warns that Russia's FSB Center 16 continues to exploit poorly configured routers globally, co-signed by 15 Five Eyes and European intelligence agencies — the broadest such coalition in recent memory. In a related geopolitical cyber escalation, the UK and EU imposed their first-ever joint cyber sanctions against Russia following attribution of the Poland power grid attack to the FSB. On the supply-chain front, the jscrambler npm package was compromised in a covert Rust infostealer campaign, and Google and Microsoft jointly pulled the ModHeader browser extension (1.6M installs) after a dormant data collector was discovered in its official store code. CISA published a postmortem on a contractor-exposed GitHub leak that left AWS GovCloud keys exposed for six months, revealing systemic reporting-channel failures. The European Commission referred four member states to the CJEU over NIS2 transposition delays and unveiled a new Cybersecurity and AI Action Plan.
