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.

Above the cover code, a top-level IIFE joins a ~140-element base64 string array, atob()-decodes it, and eval()s the result. The decoded loader queries public Ethereum RPC/Blockscout endpoints for the most recent transaction sent by hardcoded address 0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a, parses two IPv4 addresses out of the transaction recipient field, downloads an XOR-encoded JavaScript payload from staging URLs of the form http://\u003cip\u003e:443/0x/cls and http://\u003cip\u003e:443/0x/ls, and executes it via eval and a detached spawn('node', ['-e',...]) child process. Because the IIFE runs at module load, any consumer that performs require('tailwindcss-forms-styles') triggers remote code execution on the installer, with the command-and-control endpoint resolved dynamically from the blockchain so the C2 can be rotated without changing the package.","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 tailwindcss-forms-styles (npm)","id":"MAL-2026-17524","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":"tailwindcss-forms-styles","purl":"pkg:npm/tailwindcss-forms-styles","source":"MAL-2026-17524"}],"products":null,"published":"2026-10-04","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-2026-17524/"}
