A rival group of hacktivists have embarrassed hacker group Anonymous by infiltrating their Twitter account for three hours.
The intrusion follows hacks into the Twitter accounts of Burger King and Jeep in recent days and was claimed to be the work of the Rustle League.
Anonymous, a hacker collective which regularly targets governments and has successfully breached US government systems, has 160,000 followers of its @Anon_Central account.
Graham Cluley, a Senior Consultant at security firm Sophos, told the BBC: “The reason Anonymous fell victim is probably human weakness.
“Chances are that they followed poor password practices, like using the same password in multiple places or choosing a password that was easy to crack.
“Everyone should learn better password security from incidents like this – if it can happen to an account run by Anonymous supporters, it could happen to you.”
A tweet from the anonymous account yesterday afternoon said “We’re back in business!” and the collective have seemingly began a discussion with @RustleLeague on Twitter concerning cyber security since.
