@umschool/analyticsnpm
Advisory published Updated
@umschool/analytics is a confirmed malicious npm package (MAL-2026-16051) that steals credentials and exfiltrates sensitive data (malicious versions 999.0.0, 999.0.1, 999.0.2…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @umschool/analytics (npm)
What this malware does
@umschool/[email protected] targets the internal @umschool npm scope with an implausibly high version number to force resolution over any private package of the same name. Its postinstall.js runs on npm install and collects host identity (os.hostname, os.userInfo, process.cwd), reads /etc/hostname, /etc/hosts, /etc/resolv.conf, and /proc/version, filters process.env for credential-shaped keys matching a broad regex (token/secret/key/pass/aws/db/jwt/auth/etc.), and walks parent directories to read.env and config.* files. Each payload is base64-encoded and transmitted via three HTTPS GET beacons to akko.requestcatcher.com, with an additional hex-encoded DNS beacon of hostname+user to the same domain. A README/comment self-labeling the code as a 'HARMLESS PoC' does not change the observed behavior: credential-shaped environment variables, dotenv files, and internal network configuration leave the installer's build host to a third-party request-catcher.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for @umschool/analytics (5 malicious versions).
If you installed it — respond
@umschool/analytics is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If @umschool/analytics was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks @umschool/analytics-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
