Fake FDIC bank deposit insurance coverage notification leading to ZBot

This week’s malware distribution campaign, relying on a
medium size spam wave, features the abusive use of the governmental independent

Trojan.Zbot.DLO, which is, in effect, another version of the infamous ZBot.

This long-lasting Trojan is still very prolific, as proven

. This breed also has rootkit components that facilitate its
hidden installation onto the compromised machines, either in the Windows or
Program Files directory. ZBot injects code into several processes and adds
