Zeus , ZeuS or Zbot is a Trojan that performs a function in the background without the knowledge of the user. It is mainly used to spy out financial and private data, for example by logging keyboard entries in the browser, but it can also install other malicious programs . The number of computers infected with Zeus was sometimes in the tens of millions. Zeus was involved in the theft of hundreds of millions of dollars .
Zeus attacks computers that use Windows as their operating system. The majority of the infection occurs through drive-by download , i. H. through unconscious and unintentional downloading of software onto a user's computer, or through spam campaigns. Zeus contacts a control server, via which he receives instructions for further actions.
Zeus was first discovered in July 2007 in an attack on the US Department of Transportation . In early 2009 it was announced that Zeus access to over 74,000 FTP - user accounts had, including such well-known companies such as Bank of America , NASA , Monster.com , ABC , Oracle , Cisco , Amazon and Business Week .
