Today, we are going to talk about the scale of the harm that Ransomware is doing.
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. 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. Once these files are identified, the malware will encrypt them using a key known only by the attackers. In order to acquire this key to decrypt these files, the victim must pay a ransom to the attackers, often in the form of electronic currency, such as bitcoin.
CryptoWall is one of many prominent ransomware malware families, which include TorrentLocker, TeslaCrypt, and CTB-Locker, among others. The security community first discovered CryptoWall in June 2014. Since then, a number of variations of CryptoWall have surfaced. The third variant (version 3) began infecting machines in January 2015.
