Researchers at Damballa have seen the number of Kovter infections double over the last month. Kovter is Ransomware that primarily targets users of adult websites. The malware scans your browser history searching for adult websites and associated cached content. If no adult website browsing history is found, the malware will manufacture ‘evidence’ by redirecting your browser to a randomized adult website where it logs the history and retrieves content to display. While the malware can be removed, the files on the system are forever lost.”]
