Organized cybercriminals are targeting Eastern Bloc politicians and embassies, and it's still unknown who is behind the attacks, according to security firm Symantec. The attack began with a former Soviet Union country infected, which led to 60 other computers being compromised - and the infections spread throughout the rest of the year and into 2013.
"Because of the targets chosen and the advanced nature of the malware used, Symantec believes that a state-sponsored group was behind these attacks," according to Symantec. "The current campaign is the work of a well-resourced and technically competent attack group that is capable of penetrating many network defenses. It is focused on targets that would be of interest to a nation state, with spying and theft of sensitive data among its objectives."
There is growing concern of state-sponsored attacks against political rivals, with China and Russia typically blamed - but groups stemming from Iran and other foreign governments have stepped up their cyber initiatives to conduct cyberespionage.
