Source code leaked for pricey ZeuS crimeware kit
Advanced trojan development comes to the unwashed masses

Source code for the latest version of the ZeuS crimeware kit has been leaked on the internet, giving anyone who knows where to look free access to a potent set of malware-generation tools that normally sell for as much as $10,000.
Complete source code is available in at least three different locations, ensuring that it is now permanently available to the masses, Peter Kruse, a researcher with Danish firm CSIS Security, told The Reg. While the release could erode the paid market for the DIY malware kit, it could also spawn entire new kits that clone the existing code and build new features or services on top of it.
“The source code has until now been shared in very closed communities or bought by criminals with significant funds,” Kruse wrote in an email. “With the release of the entire code it's obvious we will see new versions/rebrands or improvements in general. If this grows outside of the established underground ecosystem it could have a significant impact.”
Selling in the criminal underground for anywhere from $2,000 to $10,000, ZeuS is best known as a tool for developing customized trojans that send victims' banking credentials to servers under control of the attacker. Premium versions include technical support and advanced features, such as the ability to bypass two-factor authentication offered by some financial institutions. Although there are rival crimekits such as one dubbed Eleonore, ZeuS is considered one of the most powerful and widely used of them.
But over the past year, ZeuS has undergone a fair amount of upheaval. In September, security researcher Billy Rios disclosed a serious vulnerability in ZeuS that allows whitehats and blackhats alike to seize control of botnets built using the crimekit. Around the same time, authorities in the UK, US and Eastern Europe accused dozens of individuals of laundering millions of dollars siphoned out of ZeuS-compromised bank accounts.
More recently, researchers have found evidence that the ZeuS code base has been merged with a separate crimekit known as SpyEye. And in March, CSIS's Kruse discovered ZeuS source code for sale in underground forums.
The general release of the ZeuS source code makes it all but certain that no one will pay money for the standalone version of the program, at least until its creators add must-have features to it that aren't available now. It's not clear who released the code or why.
ZeuS's growing pains resemble in many ways the challenges legitimate software packages experience as they grow in popularity.
“I do like the fact that as these crimeware softwares become more mature, the developers and maintainer will start to face the same challenges as traditional software – security patches, piracy, protecting IP, feature requests, even PR,” said Rios, who is a former security researcher for Microsoft. “I find this funny having spent some of my life worrying about the same issues as a proper security/software engineer.” ®

Re:Uhmm
I kinda don't. He certainly didn't feel bad for all those people whose money were stolen with it.
Piracy of malware lol
Honour among thieves and all that, you know.
Um...
Maybe El Reg is being responsible ?
It is their duty to report the news, but is it their duty to make malware suits even more available than they already are ?
If this was a report about a cache of Anthrax, do you really think it would be a good idea to tell everyone where it is ?
Really, common sense has not survived the millenium.
