Businesses should be far more concerned about Eastern European hackers for hire than Asian cyber snoops, according to security firm Trend Micro.
Trend Micro warned that European mercenary hackers are currently mounting far more sophisticated campaigns and attacks that their East Asian counterparts in a report entitled: Peter the Great vs Sun Tzu.
The report highlighted a significant disparity in the two regions hacker methodologies.
"The Eastern European custom-written, carefully crafted tools are designed for very specific attacks," Trend Micro security director Rik Ferguson told V3.
"Asian teams use more off the shelf stuff, things like Spyeye, Zeus, exploit kits. They go after targets that aren't bulletproof and are more widespread."
Ferguson highlighted the importance of reputation among Eastern bloc hackers as a key reason for the difference.
"You're only as good as your last hack. If a known gang gets defaced or hacked it translates into brand damage and could put the crew out of business," said Ferguson.
"Asian teams are backed, they have sponsors. This means they're larger and if things go wrong its the project not the team that is damaged."
The news follows widespread warnings within the security industry that hackers are developing new and more dangerous attacks.
FireEye issued its own report suggesting the majority of UK firms' networks have already been breached by hackers.
