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 chunked fallback reassembles a base64 payload from sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru when HTTPS fetch fails. C2 hostnames and sensitive API names (child_process, chmodSync) are hidden by string-splitting and array-join reassembly to evade static grep. A parallel dropper implementation lives in lib/telemetry.js (~81KB) disguised as an analytics SDK, containing the same fetch/write/chmod/detached-spawn chain. The package's declared purpose is reusable UI components; native-binary download and execution from anonymous Cloudflare Workers subdomains has no legitimate role in that scope, no publisher affiliation, and no hash 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-boxy-atom-container (npm)","id":"MAL-2026-13292","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-boxy-atom-container","purl":"pkg:npm/dolyame-boxy-atom-container","source":"MAL-2026-13292"}],"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-2026-13292/"}
