Citadel is a sophisticated form of malicious software or “malware” known as a “banking Trojan” designed to steal online banking credentials, credit card information, and ultimately funds through unauthorized electronic transfers. It electronically infects the computers of unsuspecting individuals and financial institutions, creating “bots”, which cyber criminals remotely control through command and control servers. Once the victim computers are infected and under control, cybercriminals remotely access the infected computers, without authorization, and steal the victims’ personal and financial information. Used by a global syndicate of cybercriminals, Citadel is believed to have infected approximately 11 million computers worldwide and be responsible for over $500 million dollars in losses.
