The Limbo Trojan: Is There an App For That?

September 19, 2009

(ChattahBox)—According to CNET, cyber criminals are now transitioning their malware and viruses to open source code, making the fraudulent programs more accessible to hackers. The cyber criminals’ new business model, so to speak, would allow hackers and virus developers to sell apps and add ons to the open source viruses, opening up a new market in the cyber fraud business.

The change to open source code allows fraudsters to benefit from the sale of more advanced versions of the viruses and opens up a whole new market for virus and trojan apps.

Uri Rivner, head of new technologies at RSA said, “It is a move to the same business model as that behind any open source project–to give away a basic version and sell more advanced versions, professional services or customizations.”

The Limbo Trojan kit previously sold for $350, before it was given away in open source code recently. However, the popular Zeus Trojan is still in high demand and sells for between $1,000 to $3,000.

The downside of making the source code for viruses publicly available, is that security experts can create programs to combat it.

Meanwhile, security experts warn computer users to be vigilant, before downloading programs or updates from Web sites and to avoid suspicious sites altogether.

According to Rivner, most computers are now infected by “drive-by downloads,” of malware that is automatically downloaded while browsing a Web site.
