The Facts
-
During a month up to 68,000 computers can be infected: the equivalent of 5,700 every day
-
Ransomware typically charges between $100 to $400 to unlock the computer
-
Ransomware is predominantly found on suspicious websites, and arrives either via a “drive-by download”, stealth download or through a user clicking on an infected advertisement. Some distribution via email has also been seen.
-
Early variants used a locked screen containing pornographic images to shame users into paying the fine, and are now using law enforcement logos.
-
Techniques have become more and more sophisticated with code built into ransomware programs to tailor messages to the right language and local law enforcement logo for example.
-
Even if a person does pay the ransom, the cybercriminals often do not restore functionality. The only reliable way to restore functionality is to remove the malware.
