commandor-clinpm
commandor-cli is a confirmed malicious npm package (MAL-2026-14172) that opens a backdoor for remote access (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in commandor-cli (npm)
What this malware does
The postinstall script in [email protected] (scripts/postinstall.js) XOR-decodes a hardcoded URL using key 'stf2026' that resolves to https://github.com/bebraz1/qPzM50V1AKG0rVlH/releases/download/null/main.exe, writes the fetched bytes to %TEMP%\main.exe, and spawns the binary detached. On WSL a companion XOR-encoded blob decodes to a powershell.exe command that pipes the same URL through to execute the binary on the Windows host, extending reach to non-Linux installers. Alongside the dropper, the script assembles a bare IPv4 address from a split array ['193','70','34','101'] and POSTs a JSON install beacon carrying the resolved platform label to http://193.70.34.101:20099/vote over plain HTTP. The download source is a personal GitHub repository unrelated to any documented publisher, the binary is opaque with no hash or signature verification, and both the payload URL and the PowerShell bridge command are stored as XOR-encoded byte arrays rather than plaintext.

Detection & response playbook
Backdoor / remote accessFind it
Search your lockfiles and build artifacts for commandor-cli (version 1.0.0).
If you installed it — respond
commandor-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.
Did it already run?
If commandor-cli 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 commandor-cli-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
