As Dizzy is reporting, UK Uncut are proudly boasting that they hacked into Vodafone’s website for about twenty minutes. Well done them.
The Police Central E-Crime Unit is a highly skilled team dealing with computer and cyber crime committed under the Computer Misuse Act 1990, primarily the offences of hacking. The sort of offences they look at are illegally hacking websites and then press releasing how and why you did it. Incidentally you can give them a call on 0300 123 1212 to report a non-emergency crime.
