Which file types do common ransomwares target?

 

Do they target executables and their libraries too?

Crypto malware will scan and encrypt just about any type of data file it finds but some target more than others. Some types like DMA Locker, Gomasom, CryptoFortress, UmbreCrypt utilize a white list of folders and extensions that they will not encrypt. By using a white list, the malware will encrypt almost all non-system and non-executable related files that it finds. Targeting critical system files and executables which could render a system unbootable serves no purpose. Since the malware developers are in business for financial gain, they need their victims to pay the ransom in order to decrypt valuable data files. A repository listing of all Bleeping Computer Crypto malware Information and ransomware topics and the files they encrypt can be found in this index.These are a few examples provided in some of the Information Guides and FAQs.
