The decoded payload queries public Ethereum JSON-RPC nodes and eth.blockscout.com/api to fetch the latest transaction sent by the hardcoded wallet 0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a, reconstructs an IPv4 address from the transaction's tx.to field (bytes 0-3 as octets), then HTTP GETs http://<ip>:443/0x/cls and http://<ip>:443/0x/ls. The response body is XOR-decoded using the x-payload-b64 header, eval()'d in-process, and additionally spawned as a detached `node -e <payload>` child process with stdio:ignore and windowsHide. All strings (module names http/https/zlib/child_process, URLs, RPC method names) are \uXXXX-escaped inside the base64 blob to defeat static string matching. The blockchain-anchored C2 (EtherHiding pattern) lets the operator rotate infrastructure by broadcasting a new on-chain transaction. This grants arbitrary remote code execution on any host that installs and loads the package. ## Source: ghsa-malware (0bbef705c23f606ecd8e4257d3de3818a1e460136c9c3aa8a5aafa1b93c0585b) 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.
