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-2026-13598/ (Markdown: https://insights.sbomify.com/MAL-2026-13598/index.md)","id":"MAL-2026-13598","markdown":"https://insights.sbomify.com/MAL-2026-13598/index.md","name":"MAL-2026-13598","record":{"aliases":[],"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, index.js loads _bootstrap.js and the main-exported lib/telemetry.js, both of which implement the same download-and-execute dropper. The code selects a platform-tagged asset path (/pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe) and fetches it from string-split, obfuscated hostnames of the form oob-worker.cf1XX-XXX.workers.dev, with a DNS-TXT chunked-base64 fallback over sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru. The fetched bytes are written to /var/tmp or the Windows TEMP directory under disguised names (.cache_\u003crand\u003e or dotnet_diag_\u003crand\u003e.exe), chmodded to 0755 via fs[\"chmod\"+\"Sync\"], and spawned detached with stdio ignored via cp.spawn(\"/bin/sh\", [\"-c\", filePath + \" \u0026\"], { detached: true, stdio: \"ignore\" }).unref() or cmd.exe /c start /b. Dangerous API names are assembled at runtime by string concatenation (require(\"child_\" + \"process\")) and the destination hostnames are reconstructed with Array.join to hide the C2 from static inspection. The 'Analytics SDK' / 'telemetry' framing does not correspond to the code's actual behavior, which is unconditional retrieval and execution of an attacker-controlled native binary on the installer's host at import time. No integrity check, pinning, or signature verification is performed on the downloaded payload.","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 dolyame-ui-selectaccount (npm)","id":"MAL-2026-13598","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":"dolyame-ui-selectaccount","purl":"pkg:npm/dolyame-ui-selectaccount","source":"MAL-2026-13598"}],"products":null,"published":"2026-08-07","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-2026-13598/"}
