Data Theft Repackaged: A Case Study in Malicious Wrapper Packages on npm
The Socket Research Team breaks down a malicious wrapper package that uses obfuscation to harvest credentials and exfiltrate sensitive data.
TypeScript port of PureScript's purescript-aff-retry package which in turn is a porting of Haskell's retry package

const result = retrying(policy, (status) => pipe(logDelay(status), TE.apSecond(fakeAPI)), E.isLeft)
result().then((e) => console.log(e))
