It has now been revealed that ransomware is one of the fastest growing malware that can harm computers today. Ransomware is a type of program that spreads to a computer and takes control of the computer. What makes it special is that the hacker who created the ransomware program demanded a ransom to restore the computer.
The Australian government recently released a report showing just how fast this ransomware is spreading around the world. It found that about 71% of businesses surveyed in 2015 were victims of ransomware attacks. The rate of spread is 13% in 2013. A ransomware program is stored on a computer like a normal virus program. It then disguises itself as a normal file on the computer so that it cannot be identified as normal. Like a Trojan program. Since then, the computer has been shut down and ransom demanded. Those methods are different.
The simplest way is to send fake but realistic warning messages. Sending messages that seem to be sent by the security forces that there is something wrong with the computer. It can also be seen sending messages that there is unauthorized software on the computer. Gives a date here. The hacker says that if the ransom demanded before that date is not paid, the computer will be deactivated. Then first lock or restrict the computer. Now extortion is demanded to restore it. The worst part is that the ransomware program encrypts the essential files on the computer. Especially cryptoviral extraction of system files on the hard disk. No expert can restore this. All you have to do is get the encryption key that only the creator of the ransomware program knows. The ransom must be paid there. Last year, a server in Tewkesbury, USA, was hit by a ransomware. The police also rescued their server by paying the ransom to the hacker.
The ransom money collected by ransomware makers is not insignificant. According to a survey conducted by Palo Alto Networks, the creators of the ransomware program Crypto Wall, which is now spreading, have earned $ 355 million as of June 2015. But this does not mean that the operators of a ransomware program have no choice but to pay a ransom and escape. That ransoms should not be paid. Experts say that computer systems should be backed up to avoid accidents.
