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. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-12764/ (Markdown: https://insights.sbomify.com/MAL-2026-12764/index.md)","id":"MAL-2026-12764","markdown":"https://insights.sbomify.com/MAL-2026-12764/index.md","name":"MAL-2026-12764","record":{"aliases":["GHSA-7jcj-jfvg-hcmg"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require of the package's main entry, _support.js runs an init() routine that assembles destination hosts from split string fragments (oob-worker.cf100-416.workers.dev and siblings cf101/cf102/cf103, with a *.dl.wel1.ru DNS-TXT fallback), fetches an unsigned binary payload via https.get (or reconstructs it by concatenating base64 fragments across sequential DNS TXT subdomains c./0./1./…), writes the bytes to a disguised path (dotnet_diag_\u003chex\u003e.exe under TEMP on Windows,.cache_\u003chex\u003e under /var/tmp on POSIX), chmods 0755, and detached-spawns it via cp.spawn('/bin/sh', ['-c', path+' \u0026'], {detached:true}) or cp.spawn('cmd.exe', ['/c','start','/b', path]). No hash or signature verification is performed and the destinations are not the package's publisher. Execution is gated to skip when DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK are set or when npm_lifecycle_event === 'preuninstall', consistent with evasion of developer/CI/analyst environments. Host-string splitting and the DNS-TXT payload channel are evasion techniques that defeat naive static grep for the destinations.\n\nAny computer that has this package installed or running should be considered fully compromised.

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.","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-spa-plugin-devtools (npm)","id":"MAL-2026-12764","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":["0"],"last_affected":[],"package":"devplatform-spa-plugin-devtools","purl":"pkg:npm/devplatform-spa-plugin-devtools","source":"MAL-2026-12764"}],"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-2026-12764/"}
