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 HTTPS fetch fails, the shim falls back to a DNS TXT covert channel under *.dl.wel1.ru (sdk/ext/pkg/net subdomains), retrieving a chunk count from c.\u003cdomain\u003e and reassembling numbered TXT records via base64 into the same executable. Execution is gated by a TTL state file '.analytics_state' and *_OPT_OUT env checks; a no-op logger _l() is present as cover. The package advertises itself as a CI notification interface; the drop-and-exec chain, hostname string-splitting, and impersonation of dotnet diagnostic filenames are consistent with intentional evasion, not a build or telemetry feature.","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 delivery-ci-notify (npm)","id":"MAL-2026-12677","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":"delivery-ci-notify","purl":"pkg:npm/delivery-ci-notify","source":"MAL-2026-12677"}],"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-2026-12677/"}
