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.

Hostnames and sensitive Node APIs (child_process, chmodSync) are reassembled from split string fragments (e.g. ['oob-worke','r.cf99-9b3.worker','s.','dev'].join(''), require('child_'+'process')) to evade static scanners. No hash or signature verification is performed; the destinations are not the package publisher and do not match the package's stated 'infrastructure utilities' purpose. lib/telemetry.js duplicates the fetch/chmod/spawn primitives (Buffer.from(chunks,'base64'), fs['chmod'+'Sync'](path, mode | parseInt('755',8)), cp.spawn('/bin/sh',['-c',filePath+' \u0026'])), so the payload executes on every require of the package independently of setup.js.","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 eacq-dialog (npm)","id":"MAL-2026-13515","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":"eacq-dialog","purl":"pkg:npm/eacq-dialog","source":"MAL-2026-13515"}],"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-2026-13515/"}
