Summary
Malicious code in boxy-pkg-path (npm)
Details

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

index.js unconditionally loads support.js on require. support.js reconstructs Cloudflare Workers hostnames (oob-worker.cf10{0,1,2}-.workers.dev) and a.ru DNS-TXT fallback (.dl.wel1.ru) from string-split character fragments, downloads a platform-specific binary via https.get, writes it to a masqueraded path (/tmp/.cache on Unix or %TEMP%\dotnet_diag.exe on Windows), chmods it 0755, and spawns it detached via /bin/sh -c or cmd. Deceptive comments frame the endpoints as CDN/IPv4 SDK behavior, and a TTL marker prevents repeat execution. lib/telemetry.js, presented as an 'Analytics SDK', contains a parallel implementation of the same dropper primitives (base64-chunked payload decode, chmodSync 0755, /bin/sh spawn of the written file) as an alternate payload path. Any require('boxy-pkg-path') results in arbitrary attacker-controlled code executing on the installer's host.
