MAL-2026-6690 Malicious code in log-taker1 (npm)

Malicious npm package published as part of a coordinated DeFi-themed infostealer campaign. log-taker1 embeds a full infostealer (~2800 lines) directly in index.js, executed at install time via postinstall: node test.js. The payload harvests cryptocurrency wallet vaults (MetaMask, Phantom, Solflare, OKX, Coinbase, TrustWallet, Backpack, TronLink), browser cookies and credentials, SSH keys, AWS credentials, .npmrc tokens, Docker config, shell history, and password manager databases, exfiltrating all data to the C2 domain log-taker.store. The C2 is shared with the rohmat2527 maintainer account.

[email protected] ships an index.js that requires child_process and invokes execSync('bash…') and execSync('zsh…') to shell out at load time. The package name ('log-taker') combined with direct execSync calls against both bash and zsh is consistent with shell-history collection — reading.bash_history /.zsh_history (or piping history / fc -l through the shell) — for off-host exfiltration. Shell history routinely contains credentials, tokens, connection strings, and hostnames, so harvesting it is credential theft regardless of any 'logging'/'backup' framing implied by the package name. The traced content also tripped the provider's malware-output safety filter, which corroborates that the code reads as operational credential-harvest logic rather than benign shell invocation.

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.
