ESG malware analysts have been receiving reports of a malware attack involving various components, which is designed to target computers running different operating systems. Mal/Krap-D is the actual backdoor component of this malware attack. Mal/Krap-D in particular targets computers with the Windows operating system. Its two variants, OSX/Dloadr-DPG and Linux/Dldr-GV, target computers with the Mac OSX operating system and different Linux distributions respectively. Mal/Krap-D is installed a result of a malicious JavaScript applet that is located on hacked websites. This malicious applet was detected recently on the website for a Colombian transport business. Due to the fact that this malware attack targets different operating systems, it is strongly recommended that Linux and Mac OSX computer users use a reliable anti-malware program to secure their computers. They are especially vulnerable due to the fact that Windows users are more accustomed to the need for anti-virus protection.

How Mal/Krap-D Enters Your Computer

Recent malware attacks targeting multiple platforms are based on exploiting vulnerabilities in third-party software. ESG malware researchers have received numerous reports of recent malware attacks exploiting vulnerabilities in Adobe products, such as Adobe Flash and Adobe Reader, and in Java, all of which are used across different operating systems. A Mal/Krap-D infection will be the result of an infection with a dangerous JavaScript applet designed to do two things:

  1. Detect the infected computer's operating system and
  2. Communicate with a remote server to download the appropriate backdoor Trojan for the targeted computer's operating system. Mal/Krap-D is the version of this backdoor Trojan used to infected computers with the Windows operating system.

Consequences of a Mal/Krap-D Infection

Mal/Krap-D is a backdoor Trojan. This means that Mal/Krap-D makes an exploitable opening in the infected computer's security. Using this security hole, criminals can access the victim's computer much in the same way as a robber can enter a building through an unguarded back door. Mal/Krap-D allows criminals to gather sensitive data from the infected computer as well as installing other malware on the infected computer. Using the backdoor established by the Mal/Krap-D Trojan, criminals can install a ransomware Trojan, a remote access tool or a keylogger Trojan to carry out any number of malicious activities on the victim's computer. Because of this, ESG security researchers consider that Mal/Krap-D is a severe threat to your computer, which should be dealt with immediately.
