Summary
Malicious code in devplatform-jscodeshift-plugin (npm)
Details

Source: amazon-inspector (92dcd946aaaf9b57795f9a94877df34a69ac39828620c58e2cf4b72cd7a9c253)

On require(), index.js loads loader.js, which reconstructs Cloudflare Workers hostnames from split string fragments (e.g. ['oob-worke','r.cf101-a','df.workers.d','ev'].join('')) and a DNS-TXT fallback channel via fragmented 'sdk.dl.wel1.ru' resolvers, downloads a platform-specific binary, writes it to /var/tmp/.cache<hex> on Unix or %TEMP%\dotnetdiag<hex>.exe on Windows, chmods it 0o755, and spawns it detached via cp.spawn('/bin/sh',['-c', fp+' &']) or spawn('cmd',...). The dropped artifacts use names impersonating telemetry / dotnet diagnostics, and environment variables like DISABLETELEMETRY/ANALYTICSOPTOUT/DONOT_TRACK are honored to provide a cover story. The package has no jscodeshift-plugin functionality and appears to be a name-squat lure whose only purpose is dropping and executing this remote payload.
