Not only did hacktivist group Anonymous take credit for launching a cyberattack against Greece’s central bank, but they also warned that more attacks are on the way.
A Bank of Greece official told Reuters on Wednesday (May 4) that Anonymous was responsible for the disruption of its website.
"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 website," the official confirmed.
The group’s attack on the central bank also came at the same time an ominous message was posted on You Tube, saying, “Olympus will fall.”
“A few days ago we declared the revival of operation Icarus. Today we have continuously taken down the website of the Bank of Greece," the video message continued. "This marks the start of a 30-day campaign against central bank sites across the world."
Last summer, the group set its sights on the U.S. Census Bureau.
The hackers leaked bureau employee data in what was deemed to be a protest against the TTIP agreement (or the Transatlantic Trade and Investment Partnership).
The hacker group claimed responsibility for the attack, in which data compromised included several thousand employee names, phone numbers, addresses and also their positions within the government. The information was published online and included password hashes.
