strapi-plugin-yesccresh-meebnpm
Advisory published Updated
strapi-plugin-yesccresh-meeb is a confirmed malicious npm package (MAL-2026-16194) that executes malicious code on install (malicious version 3.6.8). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in strapi-plugin-yesccresh-meeb (npm)
What this malware does
package.json declares postinstall: node postinstall.js, which unconditionally spawns bash with stdio redirected to /dev/tcp/14.225.210.85/443, giving the remote endpoint interactive command execution as the installing user on every npm install. The script includes a reconnect loop that re-establishes the shell on disconnect, providing persistence for the duration of the process. No user action, configuration, or runtime invocation is required for the callback to fire.

Search your lockfiles and build artifacts for strapi-plugin-yesccresh-meeb (version 3.6.8).
If you installed it — respond
Remove strapi-plugin-yesccresh-meeb from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If strapi-plugin-yesccresh-meeb 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 strapi-plugin-yesccresh-meeb-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
