Case Study: Jericho Banking Trojan

• Passwords and Credentials for Websites– Username/Login Pairs– Website Cookies– Keystrokes

• Targets Credentials for 100+ Websites– Vast majority of targeted sites are banking

and financial sites– Hiring and employment sites also targeted– Small number of technology sites targeted

Injects Into Common Applications

• Injects malicious code into common application processes– Browsers – Heavy focus on Firefox,

but also targets, IE, Chrome and Opera

– Email Clients – Outlook and WinMail– Other Apps – Skype, Java, and

Reader_sl.exe

• Allows the malware to make use of functions in those target applications– No need for the malware to import

networking libraries, it can simply use the ones already imported by the target app.
