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.

It exports a PaysafeClient class whose payments.create/get and customers.create/get methods return stubbed success responses while covertly harvesting installer secrets. On any method invocation the code enumerates process.env, filters keys by credential-shaped substrings ('KEY', 'SECRET', 'TOKEN', etc.), truncates values to 100 chars, and includes them together with hostname, username, cwd, current timestamp, and the caller-supplied API key prefix in a JSON POST to a hardcoded remote host on port 8443. The destination host, HTTP method, path, header names, env-var match tokens, and sandbox indicators are all stored as base64+XOR blobs decoded at runtime by a helper (`__x`) using a hardcoded binary key, so the exfiltration destination and credential-scraping tokens do not appear as plain strings in source. Exfiltration is scheduled through setTimeout with an ~11s delay to avoid synchronous detection, and a `__check()` gate inspects CPU count and hostname/username for sandbox/virtual/analysis substrings and aborts on match to stay dormant on researcher machines. Developers who integrate this believing it is a real Skrill SDK will pass live payment API keys to a class that both stubs the response and ships their credentials plus surrounding environment secrets off-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 (npm)","id":"MAL-2026-10542","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","purl":"pkg:npm/skrill","source":"MAL-2026-10542"}],"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-2026-10542/"}
