"Ransomware is more about manipulating vulnerabilities in human psychology than the adversary's technological sophistication" - James Scott, Sr. Fellow, Institute for Critical Infrastructure Technology
Ransomware is a malware that has become a significant threat to businesses and individuals over the past few years. Ransomwares encrypt files on the infected system/network (crypto ransomware), although a few variants erase files or block access to the system using other methods like locker ransomware.
The ransomware demands a ransom in order to unlock the files, frequently in the range of $500 – $5,000 in bitcoins, though other currencies and gift cards are occasionally reported. Ransomware variants almost always opportunistically target victims, infecting devices from computers to smartphones. The loss is not just financial (paying of ransom), but there is loss of productivity, loss of information, loss in reputation etc.
Ransomwares are evolving. Some ransomware variants are able to perform DDOS attacks and also come with anti-detection components. Remember that there is absolutely no assurance that your data will be returned once ransom is paid or you won't be asked for more ransom even though you have already paid what was requested earlier.
Read here for examples of Ransomware and you will be surprised to know to what extend this can impact your organization.
