Troj/ZbotMem-B is one of the many versions that exist of the infamous banking Trojan ZeuS. Troj/ZbotMem-B is designed to sit silently on the victim's computer until they detect that the computer user has accessed a website or application related to online banking or credit card transactions. Then, Troj/ZbotMem-B tracks the computer user's keystrokes and activity and relays this information to a remote server. Using Troj/ZbotMem-B, hackers can take over their victims' bank accounts or clone their victim's credit cards. Because of this, Zbot Trojans like Troj/ZbotMem-B pose a serious threat not only to the victim's computer's integrity, but also to the victim's financial security. ESG security researchers strongly advise that you keep your security software fully updated in order to prevent Troj/ZbotMem-B attacks. It is also essential to avoid opening unsolicited email attachments and embedded links, since these are, by far, the most common pathways towards a Troj/ZbotMem-B infection.

How Troj/ZbotMem-B Enters a Computer System
While there are many variants on the way criminals manage to invade a computer system with Troj/ZbotMem-B, this malware infection has been particularly linked to a common email scam. Criminals spoof email addresses corresponding to popular banking institutions and other companies that may involve heavy use of credit cards or online bank accounts (such as courier services or airlines) and then send out spam email claiming to contain an invoice or report of sorts. This invoice will often be disguised as a DOC (Microsoft Word) file, but is actually an executable file that, when opened, downloads Troj/ZbotMem-B from a remote server and installs Troj/ZbotMem-B on the victim's computer system. These scam emails will often contain some content so that the infection process occurs in the background without the victim's knowledge.
Unlike some kinds of malware like rogue security programs, Trojans like Troj/ZbotMem-B need to remain hidden without raising suspicions. That way, they can actively spy on the victim's online activity without alerting the computer user of their presence. If you have opened any unsolicited email messages containing a suspicious attachment or link, it is essential that you run a full scan of your computer system, so you can be sure that Troj/ZbotMem-B is not hidden within your hard drive.
