The npm package @ferudionz/webautomation exposes a single function connet(x) whose sole behavior is to POST the caller-supplied argument to a hardcoded remote URL. The entire index.js is wrapped in an obfuscator.io-style RC4 string-array (`_0x25ec=[...]`) with a self-defending anti-debug IIFE (`_0x320e22();`) that runs at require time. The destination URL is reconstructed at runtime from ~13 concatenated RC4-decoded fragments, hiding it from static inspection. The package ships no README documenting a legitimate service endpoint, has empty author metadata, and describes itself only as a generic 'logger tool'. The package name and its documented usage suggest the argument passed to connet() is a wallet/account identifier, meaning caller-supplied identifiers are silently exfiltrated to an undisclosed author-controlled destination. The combination of a hidden destination, anti-debug wrapper, and a package that presents itself under an unrelated cover story is inconsistent with legitimate logger/webautomation libraries. Judge assessment: This looks like a credential/identifier exfiltration loader disguised as a webautomation library, and the attacker model is the package author silently collecting caller-supplied data from consumers who import or invoke it. The entire `index.js` is wrapped in obfuscator.io-style RC4 string-array code with heavy hex-variable obfuscation, and the OSV advisory describes a `connet(x)` function that POSTs its argument to a hardcoded remote URL while hiding the destination at runtime. Even though the recovered IOCs are not visible in the truncated snippet, the combination of `obfuscation-hex-variables`, `obfuscation-deob-obfuscator-io`, and the advisory’s hidden POST behavior is consistent with malicious exfiltration rather than a legitimate library. The empty author metadata and unrelated package name `@ferudionz/webautomation` further support a covert supply-chain package intended to run in a victim's environment.
