MadLocker/DMA Ransomware – How Did I Get Infected

In case, you have become a victim of this nasty cyber-threat it may have happened via several different ways.
The most common method of infection by ransomware is by malicious e-mail attachments or spam links shared via such messages. The user may encounter messages that may look as if they were sent by a reputable organization, such as PayPal, eBay, BestBuy, Amazon, etc. The message topics may look like there is something urgent, for example:

  • Your account was suspended due to inactivity.
  • Click here to accept incoming payment.
  • Incoming file transfer.
  • The documents for your gift card.

Such emails may contain attachments either of commonly used file extensions such as .docx, .xml, .pdf, .jpg. or such files compressed in archives (.zip, .rar, etc.)

MadLocker/DMA Ransomware – How Does It Work

Once it has been activated on your computer, the malicious threat may drop its payload in important windows folders. Most commonly used locations are:

  • %Application Data%
  • %User%
  • %System%
  • %Temp%
  • %Windows%

After dropping its payload, it may consist of one or more modules of the following file extensions:

→.tmp; .dll; .sys; .exe; .vbs;

Each module is typically configured to perform different activities. One of those activities is that the ransomware drops a fraudulent warning message to victim computers that resembles your typical police ransom message. It claims the user has committed some kind of online crime such as downloading licensed software or worse.

Similar to other FBI Ransomware, MadLocker has also been reported by ESG researchers to use a ransomlock module to restrict affected users from accessing their computers. The ransom note aims to convince the user to pay 5 Bit coins that at the time of writing this are around 6500 US dollars. The instructions contain steps to assist the user to pay the “fine” using services like Ukash and Paysafecard.

Cyber-security researchers strongly advise users not to pay the ransom money because there have been reports that paying them will not grant access to the locked PC. The locker Trojan will not deliver as promised and will keep locking the screen until its removed by force.
