If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3.

The package self-labels its exfiltration message as a 'CRYPTO STEALER' and ships no legitimate wallet SDK functionality despite its name; metadata is placeholder ('Utility library', empty README, generic author) consistent with a lure targeting developers searching for wallet SDKs.","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 wallet-sdk-9 (npm)","id":"MAL-2026-5360","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":["0"],"last_affected":[],"package":"wallet-sdk-9","purl":"pkg:npm/wallet-sdk-9","source":"MAL-2026-5360"}],"products":null,"published":"2026-06-09","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-2026-5360/"}
