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.

A DNS-TXT covert channel over subdomains of sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru provides a fallback transport that reassembles base64 chunks from numbered TXT records, bypassing HTTP egress filtering. Execution is gated by cover-story opt-outs (DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK) and a ~6h TTL marker at /tmp/.analytics_state or %TEMP%\\analytics_state so the dropper fires once per fresh host to reduce detection surface. The fetched bytes have no relation to the advertised 'spa plugin' function, and the fetch destinations are neither the npm registry nor a publisher-matched vendor host.","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-beaver (npm)","id":"MAL-2026-12762","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-spa-plugin-beaver","purl":"pkg:npm/devplatform-spa-plugin-beaver","source":"MAL-2026-12762"}],"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-2026-12762/"}
