What this malware does

The package @quick-start-soft/quick-markdown-print was found to contain malicious code.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

This package was compromised by the Sha1-Hulud: The Second Coming NPM worm. The malicious payload steals tokens and credentials and publishes them to GitHub. The worm will propogate itself to NPM packages the user owns and establish persistence is a GitHub action. The package may also destroy the user's home directory.

The OpenSSF Package Analysis project identified '@quick-start-soft/quick-markdown-print' @ 1.4.2511142126 (npm) as malicious.

It is considered malicious because:

  • The package executes one or more commands associated with malicious behavior.

Detection & response playbook

Credential / info stealer

  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @quick-start-soft/quick-markdown-print (version 1.4.2511142126). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @quick-start-soft/quick-markdown-print across your stack and pipelines.

  2. If you installed it — respond

    @quick-start-soft/quick-markdown-print 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.

  3. Did it already run?

    If @quick-start-soft/quick-markdown-print was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks @quick-start-soft/quick-markdown-print before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions

No. @quick-start-soft/quick-markdown-print on npm has been identified as a malicious package (version 1.4.2511142126 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
