On require(), the code harvests installer secrets — filtered process.env keys matching TOKEN/KEY/SECRET/PASS/SEED/MNEMONIC/WALLET/PRIVATE/CREDENTIAL/AWS/AZURE/GCP/STRIPE/SLACK/TWILIO/NPM/GITHUB, the output of `gh auth token` invoked via child_process.execSync, ~/.npmrc, ~/.aws/credentials, ~/.ssh/* private keys, and ~/.config/solana/id.json. The collected data is JSON-stringified, base64-encoded, and POSTed (HTTPS with TLS validation disabled, HTTP fallback) to a hardcoded endpoint at 127.0.0.1:8052/exfil that the source comments label as 'C2'. The package is published under @epsteinlovekids483/crossmint-wallets-sdk-pentest, declares the legitimate Crossmint repository and the 'Paella Labs Inc' author, and ships a copied Crossmint Wallets SDK README, while internal comments state the payload is 'Injected into @crossmint/wallets-sdk'. The loopback C2 in this published build limits immediate reach on a vanilla installer, but the harvest, encoding, and POST primitives execute on every require() and the destination is a one-line change for any future republish. Importing this package as the legitimate Crossmint SDK results in theft of AWS credentials, SSH private keys, npm auth tokens, Solana keypairs, and the GitHub CLI token. ## Source: ghsa-malware (1850618fdd57bee05073c1ad031b8551ea08b949bdd10c0e956b8db6f32a123e) 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
This malicious npm package, published under the name @epsteinlovekids483/crossmint-wallets-sdk-pentest, contains code that runs immediately when required. It collects sensitive secrets from environment variables and local credential files such as ~/.npmrc, ~/.aws/credentials, ~/.ssh private keys, and Solana keypairs. It also executes 'gh auth token' to capture GitHub CLI tokens. The collected data is JSON-stringified, base64-encoded, and exfiltrated via an HTTP POST to a hardcoded local endpoint (127.0.0.1:8052/exfil) labeled as a command-and-control server. The package falsely claims association with the legitimate Crossmint SDK and Paella Labs Inc, including copying the official README. While the exfiltration endpoint is local, the code runs on every require(), enabling easy modification of the destination for future malicious republishing. Importing this package results in theft of critical credentials and keys.
Potential Impact
Importing this malicious package leads to the theft of a wide range of sensitive credentials and secrets, including AWS credentials, SSH private keys, npm authentication tokens, GitHub CLI tokens, Solana keypairs, and other environment secrets. This can result in unauthorized access to cloud services, code repositories, package registries, and blockchain wallets. The local command-and-control endpoint limits immediate remote exfiltration but the payload is designed for easy modification to enable external data theft in future versions.
Mitigation Recommendations
No official patch or remediation is available for this malicious package. The threat arises from using this specific npm package published under @epsteinlovekids483/crossmint-wallets-sdk-pentest. Users should avoid installing or importing this package. Verify package authenticity by using official sources and repositories. Monitor dependencies for suspicious or untrusted packages. Since this is a malicious package impersonating a legitimate SDK, do not trust packages with similar names from unverified publishers.
