Malicious package

@assetshop/verify-clinpm

@assetshop/verify-cli is a confirmed malicious npm package (MAL-2026-13881) that opens a backdoor for remote access (malicious versions 99.0.0, 99.0.1). Do not install it — remove it immediately and rotate any exposed credentials.

Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @assetshop/verify-cli

What this malware does

On npm install, the package's preinstall hook executes index.js, which collects installer identity and host information — whoami (via execSync), os.hostname(), os.platform(), os.arch(), process.cwd(), os.homedir(), and Node version — and transmits them to a hardcoded Interactsh/OAST callback subdomain at 5f8a1ed70fb7761d678agw9bapayyyyyb.oast.site via an HTTPS GET (with the collected values placed in the URL path) and a DNS lookup of ${user}.${hostname}.assetshop-verify-cli.<oast-host>. The package name in the @assetshop scope combined with the OAST beacon shape is the standard dependency-confusion reconnaissance pattern used to prove internal-name resolution against a private registry.

Detection & response playbook

Backdoor / remote access
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @assetshop/verify-cli (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @assetshop/verify-cli across your stack and pipelines.

  2. If you installed it — respond

    @assetshop/verify-cli establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

  3. Did it already run?

    If @assetshop/verify-cli 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 @assetshop/verify-cli 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
