ZeuS / Zbot

Zeus, also known as Zbot, is a notorious banking Trojan which infects Windows users and tries to retrieve confidential information from the infected computers. Once installed, it also tries to download configuration files and updates from the Internet. Its purpose is to steal private data from the victims, such as system information, passwords, banking credentials or other financial details. Zeus could be customized to gather banking details in specific countries and by using a vast array of methods. Using the retrieved information, cyber criminals could log into banking accounts and make unauthorized money transfers through a complex network of computers, thus leading to severe banking fraud. Operation Tovar, carried out in 2014, took down the ZeuS network of control and command servers, as it had done millions of dollars in damages and spread very quickly.
