loadashjsnpm
loadashjs is a confirmed malicious npm package (MAL-2026-14179) that typosquats a legitimate package to trick installs (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in loadashjs (npm)
What this malware does
loadashjs is a lodash typosquat whose index.js exports an empty object; the only functional code is scripts/postinstall.js, which runs automatically on npm install. The postinstall script POSTs a JSON body containing a platform label (derived in part from reading /proc/version and /proc/sys/kernel/osrelease to detect WSL) to a hardcoded bare-IP endpoint at http://193.70.34.101:20099/vote, then XOR-decodes an obfuscated URL with key 'stf2026' to https://github.com/bebraz1/aPzM50V1AKG2rVlH/releases/download/null/main.exe, downloads that PE binary to %TEMP%\main.exe and launches it detached with windowsHide. On WSL/virtualized Linux hosts, additional XOR-obfuscated byte arrays (BRIDGE_LAUNCHER_ENC, BRIDGE_SCRIPT_PRE_ENC, BRIDGE_SCRIPT_POST_ENC) are decoded and concatenated into a shell command passed to child_process.exec to invoke the same asset via a Windows-side bridge. The downloaded binary is unrelated to any advertised lodash-like functionality, is hosted under an unrelated personal GitHub account, and is fetched from an unpinned 'null' release tag.

Detection & response playbook
TyposquatFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for loadashjs (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging loadashjs across your stack and pipelines.
If you installed it — respond
loadashjs is a typosquat — you almost certainly intended a legitimately-named package. Remove loadashjs, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If loadashjs 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 loadashjs 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.

Detect & block this
O3 blocks loadashjs-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.
