Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation in the trustedCertPool function, which only parses the first PEM block from CA certificate files. An attacker can bypass certificate chain validation by providing a multi-certificate PEM bundle where only...

Researcher claims Claude Desktop installs “spyware” on macOS

Security researcher Alexander Hanff wrote an article titled Anthropic secretly installs spyware when you install Claude Desktop. Claims like that are bound to create two sides, so we searched for an official rebuttal by Anthropic. But we couldn’t find one. It would surprise me very much if they’d...
