One of the oldest active malware families, Pushdo, is again making its way onto the Internet and has recently infected more than 11,000 computers in just 24 hours. Pushdo, a multipurpose Trojan, is primarily known for delivering financial malware such as ZeuS and SpyEye onto infected computers or to deliver spam campaigns through a commonly associated components called Cutwail that are frequently installed on compromised PCs. Pushdo was first seen over 7 years ago and was a very prolific virus in 2007. Now, a new variant of the malware is being updated to leverage a new domain-generation algorithm (DGA) as a fallback mechanism to its normal command-and-control (C&C) communication methods. DGAs are used to dynamically generating a list of domain names based on an algorithm and only making one live at a time, blocking on ‘seen’ Command & Control domain names becomes nearly impossible. With the help of a DGA, cyber criminals could have a series of advantages

The year begins with the number of new variants of malware that were discovered by various security researchers. The new variants are more complex, sophisticated and mostly undetectable. Two years back in 2012, the FBI warned us about the ‘ GameOver ’ banking Trojan, a variant of Zeus financial malware that spreads via phishing emails. GameOver makes fraudulent transactions from your bank once installed in your system with the capability to conduct Distributed Denial of Service, or DDoS, attack using a botnet, which involves multiple computers flooding the financial institution’s server with traffic in an effort to deny legitimate users access to the site. But that wasn't the end; a new variant of the same family of banking Trojan has been discovered by researchers that are being delivered by cyber criminals to users’ machines, making it easier for the banking malware to evade detection and steal victim’s banking credentials.
