ProposalCrypt Ransomware – Technical Analysis

The ProposalCrypt is a ransomware cryptovirus. It seems to feature a screenlocker, as well. It will encrypt files on your computer system with one and the same extension.

ProposalCrypt ransomware could make entries in the Windows Registry to achieve persistence. Those registry entries are usually designed in a way that will start the virus automatically with each launch of the Windows Operating System. That can allow for the lockscreen to stay up, thus deeming your computer locked. The lockscreen might be bypassed easily.

The ransom note will appear inside a window. The message includes what the demands of the cybercriminals for the ransom price is, along with the other instructions and demands for decrypting your files. You can view the ransom message in the screenshot below:

The ransom note reads the following:

The cyber crooks have explicitly written inside the ransom message, that the demanded sum of money to be paid for decryption is one Bitcoin. That amount equals to 860 US dollars. However, you should NOT in any circumstances pay these cybercriminals. Your data may not be restored and nobody can give you an actual guarantee of that. Plus, giving money to the criminals can result only in supporting them financially and boosting their faith in the making of ransomware as a business model. Besides, according to malware researchers, the ransomware seems to be decryptable.
