What is MAL-2026-6501?

MAL-2026-6501 is a malicious package in wellnpm, published on 26 Jun 2026.

Official description

[email protected] ships a 24MB ELF binary named launch which is the XMRig Monero miner (RandomX, cn/upx2, ghostrider algorithm strings, libuv/OpenSSL linkage, hashvault pool references). package.json declares "main": "launch" and "scripts.start": "./launch", so running npm start on this package immediately launches the miner. A bundled config.json is pre-configured against pool.hashvault.pro:80 with the hardcoded recipient wallet 4AUTfJGTvT8A98PSE99EunfrnUbkWe9vU3FN3qsABQLP5aPKQuvWS5sCaD9WaXFQUqNtDLb9dcxiBgJiWCfjvDXp5ptWDYG, so all hashrate from victim machines is credited to the author. A second scripts.deploy script targets Android Termux: it moves libuv.so into /data/data/com.termux/files/usr/lib, chmod+x's the xmr and edit shell wrappers, and copies them into /data/data/com.termux/files/usr/bin so the miner becomes a persistent, PATH-resolvable command in the user's Termux environment. The wrappers themselves are one-liners that cd node_modules/wellnpm && npm start. README does not mention mining; metadata is placeholder (author: Your Name <wellenterprise81.gmail.com>, description: A brief description of your package). This is a cryptojacking dropper masquerading as an npm module.

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.

What should I do about MAL-2026-6501?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
