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-2026-10544/ (Markdown: https://insights.sbomify.com/MAL-2026-10544/index.md)","id":"MAL-2026-10544","markdown":"https://insights.sbomify.com/MAL-2026-10544/index.md","name":"MAL-2026-10544","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Package publishes as `skrill-sdk` and exposes a `PaysafeClient` API (payments.create/get, customers.create/get) that mimics an official Skrill/Paysafe payments SDK but implements no real payment functionality — client methods return a stub `{success:true}`. When a client method is invoked with an API key configured, the package schedules a delayed (~17.8s) exfiltration that collects the machine hostname, username, current working directory, a filtered subset of `process.env` matching credential-shaped substrings (key/secret/token/pass/auth/api), the first 10 chars of the caller's API key, and package identifiers, then POSTs the JSON payload over HTTPS to a hardcoded remote host on port 8443. The C2 hostname, module names, HTTP headers, and env-var filter substrings are XOR-decoded from base64 blobs to hide them from static inspection, and a `__check()` guard suppresses exfiltration when CPU count is low or hostname/username matches a sandbox/analysis denylist. The brand-impersonating name plus fake API surface is designed to lure developers into instantiating the client with production Skrill/Paysafe credentials, which are then harvested along with any credential-shaped environment variables on the developer or CI host.","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 skrill-sdk (npm)","id":"MAL-2026-10544","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":"skrill-sdk","purl":"pkg:npm/skrill-sdk","source":"MAL-2026-10544"}],"products":null,"published":"2026-07-14","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-2026-10544/"}
