Lucrative Ransomware Attacks: Analysis of the Cryptowall Version 3 Threat

CryptoWall is one of the most lucrative and broad-reaching ransomware campaigns being witnessed by Internet users today. Ransomware is a type of malware that encrypts a victim’s files and subsequently demands payment in return for the key that can decrypt said files. When ransomware is first installed on a victim’s machine, it will target sensitive files on said machine. These files may contain various types of information, such as important financial data, business records, databases, and personal files that may hold sentimental value to the victim, such as photos and home movies.
