Cybercrooks have developed regionally-targeted banking Trojans that are more likely to slip under the radar of anti-virus defences. Detection rates for regional malware vary between zero and 20 per cent, according to a study by transaction security firm Trusteer. This company markets browser security add-ons to banks, which offer them to consumers as a way of reducing the risk of malware on PCs resulting in banking fraud.
Trusteer cites two pieces of regional malware targeted at UK banking consumers. Silon.var2, crops up on one in every 500 computers in the UK compared to one in 20,000 in the US. Another strain of malware, dubbed Agent-DBJP, was found on one in 5,000 computers in the UK compared to one in 60,000 in the US. Source
