Postby Sophia » 2012-10-22 3:25


Computer is hold hostage for various tricky excuses? Wonder what exactly ransomware is and how to prevent? Read more.

Ransomware is a type of malware used for data kidnapping, an expoilt in which the attacker encrypts the victim’s data and demands payments for the decryption key. Technically, malware used for such purpose is sometimes called acryptovirus, cryptitrojan or cryotoworm as well.

However, the recent trend for ransomware tricks intends to be a more tricky way-pretending to be local authorities and displaying a fake message that attempts to scare and convince the victim users into paying a penalty fine, amounting to $100 -400 within a certain period, usually ranging from 36 hours to 72 hours, such as the recently notorious FBI moneypak virus.

Besides, the trend even gets further worse for users that the ransomware is somehow related to boot-sector virus now that even Mircosoft Help claims that the issue cannot be fixed directly if the computer is totally compromised and even the safe mode is forbidden because of the ransomware infection there.

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.
