Class Trojan-Spy
Platform Win32

These malicious programs are used to steal the user’s credentials for accessing various services, such as online banking. This malware can also allow a cybercriminal to remotely control the infected computer. The first malware of this type appeared in 2006–2007. Since then, many modifications and updates have been made to Trojan-Spy.Win32.Zbot. The source code was leaked in 2011. Trojan-Spy.Win32.Zbot used the BlackHole exploit kit and Cutwail and Pushdo botnets to spread.

Malware of this family has many features, including: data interception, DNS spoofing, screenshot capture, retrieval of passwords stored in Windows, downloading and execution of files on the user’s computer, and attacks on other computers via the Internet.

Several widespread modifications of this malware family exist, such as the following:

  • ZeuS Citadel
    ZeuS Citadel has several unique features: active technical support for clients and regular updates until the end of 2012 on a special forum, protection from emulation and debugging (which complicates attempts to detect and analyze the malware), and use of the AES encryption algorithm for generating an RC4 key.
  • KINS (also known as: PowerZeus, ZeusVM)
    This malware first appeared in 2011. A newer version was released two years later, in 2013. The program was used to attack German and Dutch banks.
    To resist anti-virus analysis, KINS uses steganography (hiding malicious code inside of innocent code) for storing parameters, as well as virtualization.
  • P2P Zeus (also known as: Gameover, Murofet)
    First discovered in 2011, this malware was used to create a botnet of one million infected computers. The program used peer-to-peer networking to send data to cybercriminals’ servers, as well as digital signatures for data verification. P2P Zeus was also used to spread CryptoLocker ransomware.
