DMA Locker 4.0 virus: how does it act and why is it dangerous?

DMA Locker 4.0 ransomware is the fourth edition of DMA Locker virus, a hazardous computer threat that encrypts files and urges the computer user to buy a decryption software. The authors of DMA Locker project have released DMA-Locker and DMA Locker 3.0, which were also created with purpose to swindle money from inattentive computer users. Once DMA Locker 4.0 ransomware drops its files on the compromised PC, it launches its executive file and starts the data encryption process. The fourth DMA-Locker edition does not append any file extensions to the encrypted data, therefore, it becomes harder to identify what kind of virus it is. However, DMA Locker 4.0 virus leaves some other traces which allows understanding that computer is infected with this particular virus.

DMA Locker 4.0 virus encrypts all important files on the compromised system, and then such files become inaccessible. When this malicious virus finishes the encryption procedure, it creates and saves a .txt file with instructions how to recover the encrypted data. This “ransom note” is called cryptinfo.txt and it can be found in ProgramData folder, but also in every single folder that holds at least a few encrypted files. Then this malware opens a pop-up window on the computer screen, which claims that the computer is infected with DMA Locker 4.0. This ransom note does not differ much from the one that DMA Locker 3.0 displayed: it is just a message from cyber criminals on a red background with white lock sign on the left.

DMA Locker 4.0 ransomware leaves a ransom note

The message from scammers says that all user’s files were locked and that the user has to pay up if he/she wants to access these files ever again. Just like the previous versions of this virus, the fourth version suggests to buy an exceedingly high-priced decryption key, or in other words, pay a ransom for the cyber criminals. However, it seems that cyber criminals have decided to reduce the ransom that they have used to demand. The first version of this virus asked for 15 BTC (approximately 6647 USD), and the following version asked for 4 BTC (approximately 1772 USD); meanwhile DMA Locker 4.0 malware demands 3 BTC (approximately 1329 USD).
