2fasecretkeynpm
2fasecretkey is a confirmed malicious npm package (MAL-2026-15548) that executes malicious code on install (malicious versions 1.1.2, 1.1.3, 1.1.4). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in 2fasecretkey (npm)
What this malware does
On npm install, the package's postinstall script performs an HTTP GET to http://185.14.92.233:7777/p.js, writes the response to a temp file, and launches it through a detached wscript.exe invocation of a VBS stager that runs the installer's Node executable against the downloaded payload with the window hidden (WScript.Shell.Run flag 0, detached, stdio ignored). The fetch uses plain HTTP against a hardcoded bare IP with no version pinning, hash check, or signature verification, and the executed code is not shipped in the tarball. The package's advertised purpose is a TOTP helper, which has no functional need to fetch or execute remote code at install time. The hidden-window VBS launcher conceals execution from the installing user.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for 2fasecretkey (3 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging 2fasecretkey across your stack and pipelines.
If you installed it — respond
Remove 2fasecretkey 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.
Did it already run?
If 2fasecretkey 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.
How O3 protects you
O3 blocks 2fasecretkey 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.

O3 blocks 2fasecretkey-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.
