Viruses and Digital Signatures

Very interesting stuff: http://www.symantec.com/connect/blogs/viruses-and-digital-signatures Although the files are signed, they are signed using an unauthenticated CA (Certificate Authority) which is masquerading as Verisign. A CA is a trusted third party that issues and signs the certificate and vouches for the authenticity of the file. Each CA should be registered and therefore recognized globally as a trusted signer. The signature on the certificate is verified by the signer’s public key.
