Phishing-resistant MFA could have stopped a Chinese state-sponsored threat actor from spending over a year inside North American academic and medical research networks — and we're going to tell you exactly how it happened and what you need to do about it.

A group called UNC5608, tracked by Google's Threat Intelligence Group (GTIG), exploited a vulnerability unique to REDCap — a research data platform that allows multiple software versions to run simultaneously. They got in via stolen admin credentials, planted custom malware called Infinite.red directly into REDCap's upgrade process, harvested credentials for over a year, then used those credentials to log into Google Workspace as a domain admin and create fake compliance rules to silently forward sensitive research emails — military strategy, geostrategic policy, advanced tech, specific pathogens — straight to Gmail accounts they controlled. And nobody noticed for a very long time.

Prasanna and I break down the full attack chain, then walk through every prevention layer that could have stopped it: inventory management, patching, password hygiene, SSO, phishing-resistant MFA, passkeys, DBSC, context-aware access, compliance rule monitoring, credential separation across security domains, and logging. We also get into what backups can and can't do for you in a long-dwell-time attack like this — and why infrastructure-as-code and truly immutable golden images matter more than you might think.

If you're running any kind of research platform, academic institution, or medical network — or honestly any organization that uses Google Workspace — this one's for you.
