Detection & response playbook

Malicious package
  1. Find it

    Search your lockfiles and build artifacts for sq-samsa (version 12.3.1).

  2. If you installed it — respond

    Remove sq-samsa 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.

  3. Did it already run?

    If sq-samsa 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.

Frequently asked questions

No. sq-samsa on RubyGems has been identified as a malicious package (version 12.3.1 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks sq-samsa-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.
