MAL-2026-10037: Malicious code in @wagni_bot/web3-toolkit (npm)
The npm package @wagni_bot/web3-toolkit versions 1.0.0 and 1.2.0 contains malicious code that executes automatically during installation. It scans the user's home directory and OS-specific paths for files related to cryptocurrency wallets, keystores, seed phrases, and credentials. The malicious payload exfiltrates sensitive data such as wallet keys, seed phrases, and credentials over unencrypted HTTP to a hardcoded remote server. The package provides no legitimate functionality and is designed to lure crypto developers.
AI Analysis
Technical Summary
The @wagni_bot/web3-toolkit npm package versions 1.0.0 and 1.2.0 includes a postinstall.js script triggered on npm install lifecycle hooks. This script searches for files matching wallet, keystore, seed, mnemonic, and credential patterns across various common locations including environment files, AWS credentials, SSH keys, Git credentials, and browser wallet extension storage for MetaMask and Phantom. It also scans text-based files for BIP-39 seed phrases. Collected data along with host and user identifiers are sent via plain HTTP to a hardcoded IP address (http://107.161.90.180:7777). The package lacks legitimate functionality and is a malicious lure targeting cryptocurrency developers.
Potential Impact
Sensitive cryptocurrency wallet information, seed phrases, credentials, and configuration files can be stolen from affected systems, potentially leading to unauthorized access to users' crypto assets and accounts. The data exfiltration occurs over unencrypted HTTP, exposing the data to interception. The malicious package compromises user security and privacy by harvesting critical secrets silently during installation.
Mitigation Recommendations
No official patch or remediation is currently available. Users should avoid installing the @wagni_bot/web3-toolkit package versions 1.0.0 and 1.2.0. Remove any installations of this package immediately. Monitor for suspicious network traffic to the indicated IP address and investigate any signs of compromise. Use trusted sources and verify package authenticity before installation.
