TROJ_MDROP.EVL

TROJ_MDROP.EVL is a dropper Trojan disguised as a DOC file which has been associated with a malware attack that uses a known vulnerability in Adobe Flash Player. This vulnerability, referred to as the CVE-2012-1535 exploit, is a known issue with outdated versions of Adobe Flash Player that allows criminals to execute unauthorized code on the attacked machine. Unfortunately, ESG security analysts have observed a rise in malware attacks using this vulnerability to install dangerous back doors on targeted computers. This attack will typically have two stages, involving first a Trojan dropper and then the actual backdoor Trojan. TROJ_MDROP.EVL itself is the Trojan dropper in this multi-component malware attack. In order to protect yourself from the TROJ_MDROP.EVL Trojan and similar attacks, ESG security analysts advise updating to the newest version of Adobe Flash Player. It is also crucial to be certain that your computer is protected with a reliable anti-malware program. Since TROJ_MDROP.EVL will typically be distributed through malicious spam email attachments, using a strong spam filter for your email accounts may also add a layer of protection.

How the TROJ_MDROP.EVL Attack Works

The goal of TROJ_MDROP.EVL is to use the CVE-2012-1535 vulnerability in Adobe Flash Player in order to install a backdoor on the victim's computer. When speaking about malware, PC security researchers use the term 'backdoor' to refer to an unauthorized breach in the computer's security. By using this digital backdoor, criminals can steal sensitive data or install malicious programs on the infected computer. Most dangerous malware attacks initiate with unauthorized backdoor access to a computer, which can then be used to install banking Trojans, rogue security programs, bot kits or numerous other malware threats.

How Criminals Attack Your Computer Using TROJ_MDROP.EVL

TROJ_MDROP.EVL will usually be disguised as a Microsoft Word document with the DOC extension. The most common way in which this file enters a computer is as an email attachment, commonly distributed using spam email messages. These email messages will typically try to arouse the curiosity of victims, often claiming that the attached DOC file contains important information pertaining to an online transaction or a particularly important article on current news events. However, opening this DOC file allows the TROJ_MDROP.EVL executable to run. This malware threat exploits the vulnerability mentioned above to drop malicious files belonging to a backdoor Trojan known as BKDR_BRIBA.EVL. This backdoor Trojan can then connect to a malicious URL in order to download configuration instructions, relay information on the infected computer, and install other malware on the infected computer.
