Since the older version of DMA Unlocker, which was detected at the beginning of February encrypted files that were eventually able to be decrypted, expectedly enough we now see a newer version written by cyber-crooks which uses even more advanced encryption methods. The newer version also has other changes in how it works and users who have seen its red screen illustrated further in this arStellar Phoenix Data Recovery Technicians License(Pro version with more features)ticle, should not pay the 4 BTC ransom asked to decrypt their files and seek alternative methods for file restoration.

Since the previous version of DMA Locker had flaws in it and the files encrypted by the malware were decryptable, most likely the malware writers behind it decided to update it, fixing such flaws and using even more sophisticated encryption.
At the start, the ransomware has been reported by Malwarebytes researchers to check for the following Windows processes:
- rstrui.exe
- ShadowExplorer.exe
- sesvc.exe
- cbengine.exe
If any of the processes is detected, the malware begins to close them, and it may delete your Shadow backups, in case you have any.
The DMA Ransomware also may create several different executable files in the computer upon infection. The files are differently named executables, and they may be located in the following file folders:
There are also two text files that are located in the %ProgramData% folder, named as the following:
- Cryptinfo.txt
- Date_1.txt
Besides those files, DMA Locker may create the following registry subkey, to make its malicious executable run every time upon system startup:
- In “HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run”, the REG_SZ subkey, named “{malicious exe name}”
DMA Locker 3.0 – File Encryption
To encrypt the user’s files, the ransomware uses a special module to which it executes a call type of command which sets it to action. Malware researchers report that the AES-256 encryption algorithm and after careful analysis, they believe it uses specific strategy for encrypting a file. One element may be the larger header and also, the encryptor may encrypt portions of the code of the file, not the whole code.
However, unlike the previous version, this version of DMA Locker may use a different RSA key for every file it encrypts, similar to CryptoWall 3.0. And not only this, but the ransomware also provides the user with a custom decryptor allowing him to pay the ransom money which is double now (4 BTC instead of 2 for the previous version) and decrypt the files himself.
DMA Locker 3.0 – Distribution
To be spread out into the open, DMA locker uses several different techniques. For, starters this ransomware is not focused much on hiding. In fact, its malicious executable may be distributed directly via malicious URL’s that directly download it or via email attachments. Not only this, but the malware does not delete itself after such situations leaving it open for malware researchers like the specialists in Malwarebytes to analyze it thoroughly.
