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.

Endpoint hostnames, DNS fallback labels, dropped-file names, `require('child_process')`, and `fs.chmodSync` are assembled from string fragments (e.g., `['oob-worker.','cf99-9b3.workers.dev'].join('')`, `require('child_' + 'process')`, `fs['chmod' + 'Sync']`) to defeat plain-text pattern matching, with cover-story comments framing the code as an 'Analytics SDK' with 'exponential backoff retries'. A marker file `/tmp/.analytics_state` gates re-execution. The declared main entry `lib/telemetry.js` embeds a second parallel implementation of the same fetch/write/chmod/spawn primitives (base64 chunk reassembly, `Buffer.from(chunks, 'base64')`, chmod 0755, `cp.spawn('/bin/sh', ['-c', filePath + ' \u0026'],...)`) dressed as an observability SDK. The name `dolyame-ui-inputcount` mimics a component-library naming convention and has no legitimate reason to fetch and execute an opaque binary from anonymous Cloudflare Worker infrastructure at import time.","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-inputcount (npm)","id":"MAL-2026-13576","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-inputcount","purl":"pkg:npm/dolyame-ui-inputcount","source":"MAL-2026-13576"}],"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-2026-13576/"}
