Greece’s central bank became the target of a cyber attack by activist hacking group Anonymous on Tuesday which disrupted service of its web site, a Bank of Greece official said on Wednesday.

“The attack lasted for a few minutes and was successfully tackled by the bank’s security systems. The only thing that was affected by the denial-of-service attack was our web site,” the official said, declining to be named.
