what is ransomware


Security definition Ransomware is a type of malicious software that infects your computer and displays a message asking you to pay to make the system run again. This type of malware is a criminal money-making solution that can be installed via email, instant message or deceptive links in a website. It has the function of locking the computer screen or using a password to encrypt important predetermined files. Examples of ransomware Scareware is the simplest type of ransomware. It uses intimidation or intimidation to trick victims into repaying debts. It may appear in the form of fake antivirus software, in which a message suddenly appears, claiming that your computer has various problems and requires online payment to fix them!

The level of this type of attack varies. Sometimes, users may be bombarded by endless alerts and pop-up messages. Sometimes, the computer will not work at all. However, another type of ransomware can pretend to be a law enforcement agency by opening a page that appears to be from a local law enforcement agency and claiming that the computer user has been found to be engaged in illegal activities on the Internet. The file is then locked in an encrypted file that is difficult to crack, and unless a ransom is paid, it is difficult for users to recover. A typical attack usually requires US$100 to US$200. Other attacks have a wider search range, especially if the attacker knows that holding data hostage will cause significant direct financial losses to the company. As a result, cybercriminals who carry out these scams can make a lot of money.

In either case, even if the ransom is paid, there is no guarantee that computer users will be able to fully access their systems again. Although some hackers instruct victims to pay via Bitcoin, MoneyPak, or other online methods, the attacker may also request credit card data, thereby adding another type of financial loss.

The history of ransomware In 2005, Russia reported the first case. However, since then, these scams have spread all over the world, and new types of scams still successfully target victims. In September 2013, CryptoLocker surfaced and targeted all versions of Windows! It has successfully infected thousands of personal computers and business systems. The victim unknowingly opened an email that simulated the customer support services of FedEx, UPS, DHS and other companies. After activation, the malware’s screen timer requires an average payment of $300 within 72 hours. Some versions affect local files and removable media. The United States Computer Emergency Response Team warned that the malware has the ability to jump from one computer to another, and advised users of the infected computer to immediately delete the infected computer from their network.
