Ransomware has become very frequent this year, and our malware researchers encounter more and more cases of cryptographic file-locking attacks. Easiness of deploying, the wide range of targets and clear business model are probably the main reasons for such popularity of this kind of malware among cyber criminals. Any company or organization is a potential target as it has been proven earlier this year when U.S. hospital computers and cancer treatment equipment were shut down due to ransomware. The malware infiltrated hospital network on early Feb 2016, and Medical Center forced to pay hackers 17K$
ransom for the decryption key. Some predict the cost of attacks to reach 1 billion$ by the end of 2016
. This article describes the execution flow, from the website infection to fully encrypted computer file system which later results either in paying the decryption fees or computer re-installation unless you have proper website anti-malware tools in place.
