What is the Zeus Malware?

Rogue Software

Zeus, also known as Zbot, is a Trojan horse malware that runs on different versions of the Windows OS. Creators of Zeus intended to use it to steal banking information through keystroke logging and form grabbing, but the malware has now come to be increasingly associated with the CryptoLocker malware.

The primary means through which Zeus is used to infect computers is through phishing campaigns and drive-by downloads.

Zeus Malware History

Early in its history, the malware was used to steal sensitive information from the US Department of Transportation before it become a widely distributed malware across the internet. This was in 2007 and it was not until 2009 that cybersecurity researchers realized the full-scale of infestation by which time, the malware had already infected an estimated 74,000 computers in organizations, such as NASA, Oracle, Play.com, Cisco, Amazon, Bank of America, BusinessWeek, and ABC.

In 2010, the FBI led an international crackdown of the Eastern European hackers that were believed to be behind the Zeus malware attack. The campaign led to the arrests of more than a 100 cybercriminals, 90 in the US, and the rest in the UK and Ukraine. Before their arrests, members of the cybercrime ring behind the malware had managed to steal some $70 million.

Three years after the initial arrests, a notorious hacker by the name Hamza Bendelladj was arrested in Bangkok. It is believed that he was the original creator of the Zeus malware.

Some cybersecurity teams believe that prior to his arrest, Hamza had sold all the rights, including the Zeus source code, to his primary competitor, the creator of the SpyEye Trojan.

What Does Zeus Malware do to Computers?

Once it has infected a computer, Zeus can do a number of things. It can steal information, recruit computers to further its malicious activities, or become a malware loader.

Its primary purpose, however, is to create a botnet or a network of infected computers that act as a group under the command of the malware creators. Such infected computers can then be used to launch attacks on other networks. They can also be used to gather information on organizations or to commit corporate espionage.

Although Zbot has evolved from its origins as a banking Trojan, it is still used to gather sensitive financial information about its victims. When a person visits a banking site, for instance, the malware will record the keystrokes that are used to login.
