Description

The npm package @wagni_bot/opensea-sdk is a malicious package impersonating the OpenSea SDK namespace. It contains no legitimate SDK functionality but includes a postinstall script that automatically executes upon installation. This script searches the installer's home directory and crypto-wallet paths for files containing private keys, seed phrases, and other sensitive credentials. It also reads SSH private keys and filters environment variables for secrets. All collected data, including system hostname and username, is exfiltrated via plain HTTP to a hardcoded IP address. Installing this package results in the compromise of SSH keys, crypto wallet credentials, and secret environment variables.

Impact

Successful installation of this package leads to the theft of sensitive cryptographic wallet keys, SSH private keys, and secret environment variables from the developer's machine. This exposure can result in unauthorized access to cryptocurrency wallets, SSH accounts, cloud services, and other systems relying on the compromised credentials. The data exfiltration occurs silently and over unencrypted HTTP, increasing the risk of interception but primarily enabling the attacker to gain full control over the victim's sensitive assets.

Defensive guidance

The primary mitigation is to avoid installing the @wagni_bot/opensea-sdk package entirely. Developers should verify package authenticity before installation, prefer official SDKs from trusted sources, and audit their environment for any signs of compromise if this package was installed. Rotate any exposed credentials, including crypto wallets, SSH keys, and secret environment variables, immediately upon detection.

Summary

The @wagni_bot/opensea-sdk npm package is a malicious dropper that activates during post-installation. It scans the user's filesystem and environment for sensitive cryptographic keys and credentials related to Ethereum, Bitcoin, Solana wallets, SSH private keys, and secret environment variables. The harvested data is sent unencrypted to a remote attacker-controlled server at IP 107.161.90.180 on port 7777. This package impersonates the legitimate OpenSea SDK namespace but provides no actual SDK functionality, serving solely as a credential stealer. Affected versions include 1.0.0, 1.1.0 through 1.1.5, and 1.2.0.
