Symantec has found an advanced malicious software application that appears to have been used for spying and collecting data across the globe. Named Backdoor.Regin, or simply Regin, the software is essentially a very powerful Trojan Horse that appears to have been circulating since 2008. It has been hitting government agencies, internet providers, telecom companies, airlines, industrial entities, research institutes, energy companies, and individual systems with impunity, using sophisticated encryption and targeting systems to spy on targets. It is speculated that most infections came from computers visiting "spoofed versions of well-known websites," says Symantec, though one case confirms Yahoo! Messenger was also involved.
