It’s baaack: The bot code used in the infamous, massive Storm botnet that was taken down nearly two years ago is being used to build another spamming botnet. Researchers have reverse-engineered the tweaked version of the original Storm code, which so far has spread somewhere between 10,000 to 20,000 machines. This is according to a post by DarkReading.
The article continues to state that researchers don’t know for sure whether it’s the same botnet gang that drove the original Storm and then its predecessor, Waledac — both of which are no more — but they have identified two-thirds of the same elements in this latest version as in the original Storm code version. Noticeably missing is Storm’s trademark peer-to-peer component: This version is all HTTP-based rather than the hybrid P2P/HTTP approach in the old botnet, which at one point swelled to a half-million bots. Storm began to fade away in the fall of 2008 after researchers were able to successfully disrupt its operations on more than one occasion.
