The incident that flagged it

Critical4 Aug 2026

keyv / cacheable family hijacked in Shai-Hulud "Here We Go Again" worm

On 2026-08-04 a compromised maintainer account pushed a preinstall credential stealer into the keyv / cacheable family and the worm spread via stolen npm tokens across ~2B monthly installs. Releases were cut from main, so npm signed them with valid provenance. Verified count as of the Wiz IOC feed: 443 npm packages across 2,235 versions; SafeDep's registry-backed telemetry puts the total at 1,684 versions across 420 names tied to nine orgs.

Versions named here: 6.2.1, 6.2.2, 6.2.3, 6.2.4, 6.2.5, 6.2.6, 6.2.7

What to do if you installed one of these

Treat the machine as compromised rather than simply upgrading. Packages in these incidents typically execute at install time, so the payload has already run with whatever credentials were in the environment.

1.Rotate every credential that machine or CI job could reach - registry tokens, cloud keys, SSH keys, CI secrets - from a different machine.
2.Pin to a version not listed above, then reinstall from a clean lockfile.
3.Clear caches and private mirrors. Artifactory, Nexus, Verdaccio, and devpi routinely keep serving a tarball after the public registry has pulled it.
4.Read the incident write-up above - recommended actions differ per incident, and some have specific indicators of compromise worth grepping your logs for.

Check your whole project

@servicetitan/tanstack-query-mobx is one of many packages in these incidents, and it is usually pulled in as a transitive dependency rather than one you installed directly. Paste your package-lock.json to check every dependency at once - it runs in your browser and nothing is uploaded.
