TeslaCrypt .micro Extension Ransomware – Distribution
The TeslaCrypt 3.0 version may be spread by Trojan horses, just like its previous version was spread through the Miuref.B Trojan. That normally happens when you visit suspicious sites and click on links with malicious code without knowing.
An effective distribution method for the ransomware remains spam emails with malicious file attachments. The attachments can be some archives or executable files. There are reports that some of the malicious files may infect computers by running compromised macro commands of Microsoft Office or Adobe programs.
The .micro Extension Ransomware – Details
When activated on your computer, the ransomware creates a randomly named executable file on the User profile in the following location:
After this file is executed, it creates an entry in the Windows Registry. The name of the entry is “meryHmas” and its location is:
That enables these files of the ransomware to be read and run with each start of the Windows operating system.
The .micro extension variant may also create more entries in the Windows Registry, as follows:
→HKCU\Software\[random name] HKCU\Software\xxxsys
Then TeslaCrypt 3.0 begins searching files to encrypt and lock them with the .micro extension. The known file formats it scans for are listed right down here, but it may not be a full list.

After successful encryption, the ransomware creates other files on your desktop and links to other locations that contain the ransom note with the payment instructions. The files are named as:
These instructions are nearly identical to another nasty ransomware, called CryptoWall 3.0. Researchers think that this message has been used to simplify and outsource the ransom payment using CryptoWall’s methods or to hide the real identity of the malware.
This ransom message has instructions on how to use the Tor network to reach the cyber-criminals via an anonymous connection and make the ransom payment. It is strongly advised NOT to pay the ransom money demanded by the TeslaCrypt 3.0 creators since it is no guarantee you will get a decryption key to restore your files. Also, if you pay the ransom, you are funding the cyber-criminals to further sophisticate their work, and they can use the money for many other ill deeds.
