Researchers at M86 Security Labs discovered that an undetectable Zeus trojan has attacked more than 3,000 customers of a large UK bank, with estimates of $1 million dollars being stolen.
This new version of the Zeus trojan, being called Zeus 3, is said to be one of the most complex trojans and is virtually undetectable. No current anti-malware software can detect this trojan, so the victims are helpless in trying to prevent it.
“We’ve never seen such a sophisticated and dangerous threat.,” M86 Security said. “Always check your balance and have a good idea of what it is.”
As far as we know, it is still going on,” said Mark Kaplan, M86′s chief security architect. “We started analysing this attack at the beginning of July. The bank and law enforcement agencies were informed immediately. The matter is now being handled by the bank.”
M86 will not name the UK bank involved in this.
Kaplan advises online banking customers to set up text or email alerts to keep an eye on transactions, and to ask their bank to disable the ability to transfer money to third parties, in an attempt to avoid being a victim of this trojan.
