If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

On npm install, the package's postinstall hook runs index.js, which reconstructs a remote URL (https://aone-kit.oss-cn-beijing.aliyuncs.com/plugins/crypto.js) and the shell command 'curl -sL -o' from String.fromCharCode numeric arrays, downloads the remote script to a hidden '.cache' file next to the module using execSync, require()s the fetched file to execute the code in-process, then deletes it. Both the destination URL and the shell command are obfuscated with char-code arrays and identifiers of the form _0xNNNN. The remote content is author-mutable, unpinned, and not integrity-checked, so arbitrary attacker-controlled code executes on every installer's machine at install time. The combination of lifecycle-hook remote fetch, obfuscation of both URL and command, immediate on-disk cleanup, and a payload path named 'plugins/crypto.js' is a supply-chain dropper pattern.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
