If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The fetched bytes are written to /var/tmp or %TEMP% under names mimicking legitimate tooling (.cache_\u003chex\u003e, dotnet_diag_\u003chex\u003e.exe), chmod 755'd, and spawned detached via /bin/sh -c or cmd.exe. Every network destination, the `child_process` require, and `chmodSync` are assembled from split-string arrays joined at runtime to defeat static analysis. A second, structurally identical dropper is shipped in lib/telemetry.js (~81 KB, disguised as an analytics SDK): base64-assembled bytes, chmod 755, `cp.spawn('/bin/sh', ['-c', filePath + ' \u0026'],...)`; it is not reachable from index.js in this version but is present in the tarball. The package name resembles the legitimate `cra-template` family, consistent with a typosquat lure delivering remote code to any consumer that requires it.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in devplatform-cra-template (npm)","id":"MAL-2026-12706","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"devplatform-cra-template","purl":"pkg:npm/devplatform-cra-template","source":"MAL-2026-12706"}],"products":null,"published":"2026-08-05","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-12706/"}
