Summary
Malicious code in statist-browser-typed-client-jumptaxi.feature.contacts (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (534768cd8d709ca1a5701f182e4e509713821923b6995a2bb868d79b0fdded62)

On require of the package (index.js loads./vendor at import), vendor.js selects a platform-specific staging path, downloads a binary from a rotated list of Cloudflare workers.dev origins whose hostnames are reconstructed at runtime from split-string arrays joined together, with a DNS TXT covert-channel fallback that reassembles base64 chunks from numbered subdomains under dl.well1.site. The fetched bytes are written to /var/tmp or %TEMP% under cover-story filenames (.cache<rand>, dotnetdiag<rand>.exe,.analyticsstate), chmod 0755, and spawned detached via /bin/sh -c or cmd.exe /c start. No hash or signature verification is performed and destinations are not first-party publisher infrastructure. Any consumer that imports this package auto-executes an attacker-controlled native payload on the installer's host.
