How Trojan.Powelik Enters Protected Computer?

As a Trojan horse, Trojan.Powelik is capable of packaging itself as a computer/browser friendly program featuring powerful functions. It then was put onto some phishing websites or advertising platforms to trick people into downloading. Or, the Trojan horse simply piggybacks on other types of computer threats for dissemination. There are cases when Powelik Trojan attacks loosely programmed website or applications to spread itself.

But there’s one way that Powelik Trojan lands onto a machine without tricks. That is Powelik Trojan hacks the backdoor of some installed program it uses for real-time improvement or rectification or capitalizes the bug/loopholes found on a compromised machine for infection. Therefore, it is kindly suggested not to download and install loosely programmed, freeware or shareware and to check computer security regularly for timely fix.

  1. Powelik Trojan attacks kernel mode device drivers that directly tell how a program works.
  2. The cunning Trojan horse covers up its traces by confusing the man-made security tools with similar or the same file names as the system ones’.
  3. In need of more backup and cover ups, Powelik Trojan access them through gateway; so it inserts its codes into Dllhost.exe.

Even the security utilities are so intelligent that they have removed and exterminated many computer threats, they are not able to differentiate the real system files from the fake ones based on names instead of content. When the fake ones are inserted into Windows Protected Folders, the background processes and drivers concerned will turn to work for Trojan.Powelik.
