Ransomware-A Growing Menace

Ransomware attacks grow as one of main profitable cyber scams for malware authors.  Ransomware that locks a computer and uses law enforcement imagery to intimidate victims has spread from Eastern Europe to Western Europe, the United States, and Canada over the past year. The scam has been copied and professionalized from initial early attacks, with established online criminal gangs now branching out into the scheme. Each gang has separately developed or bought their own different version of the ransomware. This malware is highly profitable, with as many as 2.9 percent of compromised users paying out. An investigation into one of the smaller players in this scam identified 68,000 compromised computers in just one month, which could have resulted in victims being defrauded of up to $400,000 USD. A larger gang, using malware called Reveton, was detected attempting to infect 500,000 computers over a period of 18 days. Given the number of different gangs operating ransomware scams, a conservative estimate is that over $5 million dollars a year is being extorted from victims. The real number is, however, likely much higher.

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.
How Does Ransomware Infect Computers? 

A ranomware program can be installed from an e-mail attachment, an infected program, or a compromised or malicious websites. Besides, the newer type of ransomware uses Trojans to spread out as well.
