The widespread availability of the Zeus Trojan source code is a challenge and an opportunity that security resellers need to take advantage of.
Earlier this month the source code for one of the worst pieces of malware was leaked, the jury is still out over if it was accidental or deliberate, handing a large number of e-criminals access to inspiration from Zeus.
With blended threats on the rise the prospect of more criminals getting access to malware code will make the problem worse and should be seized as an opportunity for resellers to talk to customers about the need for greater protection.
"More criminals are going to have access to the Zeus toolkit and that is going to make them think and that's not going to be a good thing," said Tim Warner, vice president of UK Sales at M86Security.
"Zeus has been consistently nasty and the most talked about malware over the last two years," he added.
One of the fears that many in the security industry have, including Warner, is that not only will more criminals use Zeus but those behind the malware will establish an unofficial app store type system selling updates and patches to the code.
