ecto-cargo-wk1tm59anpm
Advisory published Updated
ecto-cargo-wk1tm59a is a confirmed malicious npm package (MAL-2026-10893) that steals credentials and exfiltrates sensitive data (malicious version 99.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in ecto-cargo-wk1tm59a (npm)
What this malware does
Package [email protected] exhibits several contextual red flags worth human review: a randomized-suffix name pattern (-wk1tm59a) typical of disposable/throwaway publishes, an inflated 99.0.0 version typical of dependency-confusion / proof-of-concept publishes, and only 3 files in the tarball. Automated content inspection of the package's code did not produce a usable trace, but the content was non-trivial enough that an automated description could not be produced. No specific attacker domain, exfiltration endpoint, or install-time fetch-and-execute behavior has been concretely identified from the available evidence, so a public block verdict is not justified, but the combination of disposable-name shape, 99.0.0 version inflation, and untraced contents warrants human inspection before this package is trusted.

Credential / info stealerFind it
Search your lockfiles and build artifacts for ecto-cargo-wk1tm59a (version 99.0.0).
If you installed it — respond
ecto-cargo-wk1tm59a 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 ecto-cargo-wk1tm59a 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 ecto-cargo-wk1tm59a-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
