Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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-2026-13264/ (Markdown: https://insights.sbomify.com/MAL-2026-13264/index.md)","id":"MAL-2026-13264","markdown":"https://insights.sbomify.com/MAL-2026-13264/index.md","name":"MAL-2026-13264","record":{"aliases":["GHSA-jrqw-cq63-whp7"],"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 this package, index.js loads _helpers.js which selects an OS/arch-specific path and downloads a native binary from one of three Cloudflare Workers hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev) whose hostnames are reconstructed at runtime via array.join(\"\") to evade static analysis. The binary is written to /tmp or the Windows Temp directory under disguised names (dotnet_diag_\u003chex\u003e.exe,.cache_\u003chex\u003e), chmod 0755'd, and spawn-detached via /bin/sh -c \"\u003cpath\u003e \u0026\" or cmd.exe /c start /b. A DNS-TXT covert-channel fallback under *.dl.wel1.ru (sdk./ext./pkg./net.dl.wel1.ru) reassembles the payload from base64-encoded TXT records (count record c.\u003cdomain\u003e, chunk records i.\u003cdomain\u003e) when HTTPS delivery fails, then writes and executes the same way. A lockfile named.analytics_state and dotnet_diag-style filenames provide the cover story. This grants full remote code execution to whoever controls those endpoints on any machine that installs or imports the package.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. 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-sre-devplatform-sre-core (npm)","id":"MAL-2026-13264","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-sre-devplatform-sre-core","purl":"pkg:npm/devplatform-sre-devplatform-sre-core","source":"MAL-2026-13264"}],"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-2026-13264/"}
