'Speaking to AFP, military spokesman Mikael Abramsson said that a server in the Swedish defense system had a flaw which was exploited by hackers to carry out the attacks, confirming a report in the Swedish daily DN.
'"The hacking attack was a kind of wake-up call for us and forced us to take very specific security steps to prevent such a thing from happening again," he said.
'"We cannot be more specific about the new security measures we put in place, but such an attack could not happen again."
'The servers were used in a so-called DDoS attack (distributed denial of service) which pounded the websites of US financial institutions, among Citigroup, Capital One and HSBC with overwhelming requests for information.'
