On every require/import of the package, the decoded payload queries an Ethereum RPC/Blockscout endpoint for the latest transaction of the hardcoded EOA 0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a, interprets the 20-byte tx.to address as two encoded IPv4 addresses, and issues HTTP requests to http://<resolved-ip>:443/0x/cls and http://<resolved-ip>:443/0x/ls. The response carries a payload in the x-payload-b64 header that is XOR-decoded and then executed via spawn('node', ['-e', <decoded>], {detached: true, stdio: 'ignore', windowsHide: true}).unref(), launching a detached hidden Node process on the installer's machine. Module identifiers such as 'http', 'https', 'child_process', and 'spawn' are unicode-escaped (\\u00XX) to further hide the behavior. The combination of on-chain C2 resolution (resistant to DNS/domain takedown), multi-layer obfuscation, and hidden detached process execution on import is a remote-code-execution supply-chain attack against any project that installs this version.\n\n## Source: ghsa-malware (037f3ed4ca92b64733adaadc02c839d4fc180a4547c0a191cefb45a57e8833d5)\nAny computer that has this package installed or running should be considered fully compromised.
