In the month since activist hacking group Anonymous pledged to target banks across the world, senior officials have said the public websites of the central banks of both Indonesia and South Korea have been hit by cyber attacks. In response to the attempted hacks, Bank Indonesia has blocked 149 regions that do not usually access its website, including several small African countries, deputy governor Ronald Waas told Reuters. Waas said several central banks were hit by similar attacks and were sharing the IP addresses used by the perpetrators. According to officials, no money was lost in the attacks on Bank Indonesia and the Bank of Korea, which were mainly distributed denial of service (DDoS) attempts. They also said there is no word on who is responsible for the attacks.
