## What is MAL-2026-12697?

MAL-2026-12697 is a malicious package in devplatform-api-v2-resources-metadata, published on 5 Aug 2026. 

### Official description

Package presents itself as a REST API client wrapper, but requiring it loads _platform.js which detects the host OS/architecture, fetches a platform-matched native binary from three string-concatenation-obfuscated Cloudflare Workers mirrors (oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev) with a DNS-TXT chunked base64 fallback under sdk/ext/pkg/net.dl.wel1.ru, writes it to /var/tmp or %TEMP% under disguised names (.cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmods 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start /b. An mtime lockfile at /tmp/.analytics_state gates re-triggering. Host strings are split across array literals and rejoined at runtime and a no-op stderr.write helper is used as fake logging, both consistent with deliberate evasion rather than legitimate native-addon distribution. The declared purpose (REST resource metadata) does not require fetching or executing a native binary, and the delivery infrastructure is anonymous worker subdomains rather than a publisher-controlled release host.

## What should I do about MAL-2026-12697?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
