Detection & response playbook

Malicious package

  1. Find it

    Search your lockfiles and build artifacts for @twork-data-services/proxy-ips-account-account-number-prepaid-card-limits (2 malicious versions).

  2. If you installed it — respond

    Remove @twork-data-services/proxy-ips-account-account-number-prepaid-card-limits 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 @twork-data-services/proxy-ips-account-account-number-prepaid-card-limits 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.
