The fetched bytes are written to /var/tmp/.cache_<hex> or %TEMP%/dotnet_diag_<hex>.exe under cover names, chmod'd 0755, and spawned detached via cp.spawn('/bin/sh', ['-c', fp+' &'], {detached:true}).unref() or spawn('cmd',...). A second dropper is shipped in lib/telemetry.js (~81KB, disguised as an 'Analytics SDK') containing the same primitives (base64 chunk decode, chmodSync 0755 on 'extensionPath', cp.spawn('/bin/sh', ['-c', filePath+' &'])), with child_process required via the computed string require('child_'+'process').

The npm package streak-math-kit version 1.0.0 contains malicious code that targets Windows Subsystem for Linux (WSL) developer environments. When imported, it drops a hidden Windows executable named vite-native-helper.exe into the Windows startup folder of a detected user profile, causing persistent execution on every Windows logon. The malicious behavior is obfuscated by hex-encoding path segments and the executable binary. This results in a persistent backdoor on Windows systems accessed via WSL.

The downloaded bytes are written to `/var/tmp` or `%TEMP%` under disguised names mimicking system utilities (`.cache_<rand>` on Unix, `dotnet_diag_<rand>.exe` on Windows), chmod'd 0755, and detach-spawned via `/bin/sh -c '<path> &'` or `cmd.exe`. A freshness marker is stored as `.analytics_state` and stderr is silenced by a no-op logger. A second, larger copy of the same dropper is shipped as `lib/telemetry.js` under an 'analytics SDK' cover story, using additional string-concatenation obfuscation (`require("child_" + "process")`, `fs["chmod"+"Sync"]`); it is not referenced by the current index.js but is bundled at the tarball root. The package is advertised as a 'lightweight images wrapper' — the dropper behavior is unrelated to that purpose, the destinations are author-controlled and obfuscated to defeat scanners, and the delivered bytes are an opaque native executable with no publisher provenance, integrity check, or version pinning. ## Source: ghsa-malware (c1380a3b63e9f71c1a3d2d58040216fe5ffc0a0b27291d8d4596224f1ee6aa64) 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.

Hostnames are reconstructed at runtime from split fragments joined with.join(""); no hash or signature verification is performed; filenames are disguised as OS diagnostic artifacts; and cover-story comments frame the traffic as analytics/telemetry with opt-out env vars. The tarball additionally ships an unreferenced lib/telemetry.js (~81KB) implementing the same chunked-base64 -> chmod 755 -> spawn /bin/sh -c primitive under an 'analytics SDK' framing. ## Source: ghsa-malware (8afab21233c95b25115b15ecca1c2db5f3d03aaac132d89443c4836cc4d68093) Any computer that has this package installed or running should be considered fully compromised.

The downloaded bytes are written to /tmp or the Windows Temp directory under disguised names (.analytics_state, dotnet_diag_*.exe,.cache_*), chmodded to 0755, and spawned detached via /bin/sh -c '<path> &' or cmd.exe /c start. A DNS-TXT covert-channel fallback under subdomains of dl.well1.site (tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site) reassembles a base64-encoded binary from TXT record chunks when HTTPS fetch fails, feeding the same write+chmod+spawn chain. The child_process module name is constructed as require('child_' + 'process') and chmodSync is accessed as fs['chmod'+'Sync'] to further evade pattern matching. Environment variables DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, and DO_NOT_TRACK are checked to give the behavior a telemetry cover story. lib/telemetry.js contains a parallel dropper implementation with the same primitives, wrapped in 'Analytics SDK' comments. The package name resembles a legitimate Keycloak client but the shipped code performs installer-side arbitrary code execution rather than any Keycloak functionality. ## Source: ghsa-malware (d96ef446f7a474a7855c2746501c889834693353fd5d40db11171180af0ead0a) Any computer that has this package installed or running should be considered fully compromised.

Environment variables DISABLE_TELEMETRY/ANALYTICS_OPT_OUT/DO_NOT_TRACK gate activity and a /tmp/.analytics_state stamp file rate-limits re-execution.
