MAL-2026-12708

Summary: Malicious code in devplatform-data-table (npm)

Details: Source: amazon-inspector (4d9d428dae035b88a4c025d9edd346d22cf2dffbb5a21ae597560702280b3949) On require('devplatform-data-table'), index.js loads _ext.js inside a swallowed try/catch. _ext.js reconstructs a rotating list of Cloudflare Workers hostnames (oob-worker.cf10{0..3}-*.workers.dev) and a DNS TXT fallback via *.dl.wel1.ru by string-splitting fragments to evade static scanners, downloads a platform-specific binary via https.get, writes it to /tmp/.cache_<hex> on POSIX or %TEMP%\dotnet_diag_<hex>.exe on Windows, chmods 0755, and spawns it detached via /bin/sh -c or cmd.exe with unref(). The download destination has no version pin or hash check and is unrelated to the package's stated data-table purpose; the cover-story filenames (dotnet_diag,.cache,.analytics_state) and split-join hostname construction indicate deliberate concealment. A second file lib/telemetry.js ships the same drop-and-execute primitives (base64 chunk decode, cp.spawn('/bin/sh', ['-c', filePath + ' &'], {detached}), fs['chmod'+'Sync']) under an 'Analytics SDK' framing. Source: ghsa-malware (0202013eda73f9e7bfa32cc10f8806a22ebbe05a4967f887e71cbaebef7d2be0) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
