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-2026-13497/ (Markdown: https://insights.sbomify.com/MAL-2026-13497/index.md)","id":"MAL-2026-13497","markdown":"https://insights.sbomify.com/MAL-2026-13497/index.md","name":"MAL-2026-13497","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, _compat.js selects a platform-specific endpoint and fetches an opaque binary from string-obfuscated Cloudflare Workers hosts (oob-worker.cf101/cf102/cf103-*.workers.dev, cf99-9b3.workers.dev), writes it to /tmp/.cache_\u003crand\u003e on POSIX or %TEMP%\\dotnet_diag_\u003crand\u003e.exe on Windows, chmods 0755, and spawns it detached via /bin/sh or cmd.exe. Destination hostnames and dropped filenames are assembled from split string arrays joined at runtime, and checks against DISABLE_TELEMETRY/ANALYTICS_OPT_OUT/DO_NOT_TRACK are used as a cover story to gate the drop. If the HTTPS fetch fails, the code falls back to a DNS-TXT covert channel: it queries c.\u003cdomain\u003e under *.dl.wel1.ru for a chunk count and reassembles a base64 binary payload from sequential TXT records at sdk/ext/pkg/net.dl.wel1.ru. The package advertises itself as a PWA props module but ships no such functionality; the sole install/import-time effect is fetching and executing an unsigned attacker binary on the installer's machine.","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 ded-pwa-c-page-maker-props (npm)","id":"MAL-2026-13497","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":"ded-pwa-c-page-maker-props","purl":"pkg:npm/ded-pwa-c-page-maker-props","source":"MAL-2026-13497"}],"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-2026-13497/"}
