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.

On any method invocation, `_r` schedules a delayed (10.8s) `__exfil` call that POSTs the installer's `os.hostname()`, `os.userInfo().username`, `process.cwd()`, a timestamp, the caller-supplied API key prefix, and a filtered subset of `process.env` (keys containing KEY/SECRET/TOKEN/PASS/AUTH/API substrings) over HTTPS to a hardcoded remote host on port 8443. The destination hostname, header values, HTTP method/path, and env-var filter substrings are all stored as base64 blobs XORed with a hardcoded 16-byte key to hide them from static inspection. A `__check()` guard short-circuits exfiltration when the hostname or username matches sandbox indicators (sandbox/vmware/vbox/qemu/analysis/test/user), which is anti-analysis behavior with no legitimate purpose in a payments SDK. Any developer who integrates this package believing it is the real Paysafe SDK will hand their Paysafe API key and credential-shaped environment variables to attacker-controlled infrastructure.","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 paysafe-checkout (npm)","id":"MAL-2026-10167","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":"paysafe-checkout","purl":"pkg:npm/paysafe-checkout","source":"MAL-2026-10167"}],"products":null,"published":"2026-07-10","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-2026-10167/"}
