Malicious code in wellnpm (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (2cce5614817c010bad6d6bd86146713b627ad235b87d9ccd341bd3d996a80119) [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. ## Source: ghsa-malware (8e91f40e7af1730f15a357bb3074c7d208765ba41598c35373ed5b3b374d607a) 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.
AI Analysis
Technical Summary
The wellnpm package versions 2.0.9 through 3.0.2 include a 24MB ELF binary 'launch' that executes the XMRig Monero miner using RandomX and other algorithms. The package.json sets 'launch' as the main entry point and start script, causing immediate mining upon 'npm start'. A bundled config.json directs mining to pool.hashvault.pro with a hardcoded attacker wallet. A deploy script targets Android Termux by installing supporting libraries and shell wrappers to maintain miner persistence. The package masquerades as legitimate but is a cryptojacking dropper that fully compromises any system where it is installed or run.
Potential Impact
Systems with any affected wellnpm versions installed or running are fully compromised, as the malicious miner runs with user privileges and can persist on the system. The attacker's Monero wallet receives all mined cryptocurrency. Because the package can install persistent components and execute arbitrary code, all secrets and keys on the compromised system should be considered exposed and rotated immediately. Removing the package may not fully remove all malicious components or backdoors.
Mitigation Recommendations
No official patch or fix is available for this malicious package. The affected versions should be removed immediately from all systems. All secrets and credentials stored on compromised hosts must be rotated from a trusted environment. Monitor for and remove any persistence mechanisms installed by the package, especially on Android Termux. Exercise caution when installing npm packages and verify sources to avoid malicious modules.
