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.

The payload is written to /tmp under a hidden dot-file name (or to Windows Temp as dotnet_diag_*.exe), chmod'd 0755 via fs['chmod'+'Sync'], and spawned detached with cp.spawn('/bin/sh', ['-c', filePath+' \u0026'], {detached:true}) or the cmd.exe equivalent. A secondary delivery path resolves DNS TXT records under *.dl.wel1.ru (c.\u003cdomain\u003e for chunk count, N.\u003cdomain\u003e for each chunk), concatenates the base64 payload, and executes it the same way. Sensitive API names (child_process, chmodSync) and destination hostnames are split-string-obfuscated to evade static analysis. The 'Analytics SDK' framing in lib/telemetry.js duplicates the same fetch-write-chmod-exec chain. Installing and importing the package fetches and runs opaque attacker-controlled native code on the developer's machine with no pinning or signature verification.","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-scrollblock (npm)","id":"MAL-2026-13597","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-scrollblock","purl":"pkg:npm/dolyame-ui-scrollblock","source":"MAL-2026-13597"}],"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-2026-13597/"}
