Police themed ransomware is  a devastating computer virus, which often infiltrates targeted computer system with the help of Trojans and once take the system, it will lock up the entire computer system and display a crafted  notification in name of local authority, mostly local police, to make up various excuses for a “fine’ to be paid via prepaid codes. Using social engineering tactics, the scam message of Police themed ransomware are very tricky, which often stated that the infected computer is involved in illicit activities online like the victim has been using the computer to distribute malware, porn graphical materials, or visit some porn websites, or illegally use copyrighted content, etc.

No wonder that ransomware tricks have been in the wild for so long although the security industry and the real Police authorities related have been making efforts to warn people and arrest those cyber crooks.

Such threat is distributed through several means. Malicious websites, or legitimate websites that have been compromised, may drop ransomware Trojan onto a compromised computer. This drive-by-download often happens surreptitiously. Another method used to propagate this type of malware is spam email containing infected attachments or links to malicious websites. The threat may also be downloaded manually by tricking the user into thinking they are installing a useful piece of software.
Ransomware are also prevalent on peer-to-peer file sharing websites and is often packaged with pirated or illegally acquired software.

Ransomware is not new

 

A paper entitled “Cryptovirology: Extortion-Based Security Threats and Countermeasures,” written by security experts at Columbia University and IBM, clearly outlined the concept back in 1996. In the past, though, data kidnappers targeted businesses rather than individuals. In March 2006, ransomware known as Crypzip or Zippo circulated to private users on the Internet. Recipients of the Trojan horse program also received an e-mail ransom note demanding $300, to be paid by electronic transfer, for the key required to unlock all their files.
