It's bad enough that one hacker group has been wreaking havoc on banking systems worldwide, but it's apparently getting worse. Security firm Symantec reports that a second group, Odinaff, has infected 10 to 20 of its customers with malware that can cover up bogus money transfer requests sent through the ubiquitous SWIFT (Society for Worldwide Interbank Financial Telecommunication) messaging system. Most of the attacks targeted Australia, Hong Kong, the UK, the Ukraine and the US. And unlike the initial attackers, Odinaff appears to be a criminal organization (possibly linked to the infamous Carbanak team) rather than a state-sponsored outfit.
