Botnet
TeamBot
aka FINTEAM
Recently, Check Point researchers spotted a targeted attack against officials within government finance authorities and representatives in several embassies in Europe.
TeamBot, also known as FINTEAM, is a Windows botnet.
Background
Check Point researchers observed a campaign aimed at staff in government finance bodies and at embassy personnel across Europe. Infection begins with a malicious attachment posing as a classified US document, and the operation abuses TeamViewer, the widely used remote-access and screen-sharing tool, to seize complete control of the victim's machine. The takeover is accomplished by sideloading a rogue DLL alongside the legitimate TeamViewer files.
