Rezm is a file-encrypting computer virus that obstruct users from opening their personal files and demands a ransom fee in order to retrieve access. Ransomware operators mostly order to settle the payment through crypto-currency or credit card, as much as possible.
Developers have several ways to infect computers with ransomware. One of the most efficient and common methods nowadays is via malicious spam emails, which is used to distribute ransomware like Rezm. Such emails may consist of deceptive attachments, or any subjects that might be of interest for target victims.
For Rezm ransomware, developers ought to trick people into opening attachments from their email. They present their victims with legitimate-looking correspondence acting that they are from a trusted institution or well-known companies. However, opening the attachment will automatically activate Rezm ransomware on the operating system.
Another effective technique of Rezm is through malicious advertisements. The use of online advertising in spreading Rezm ransomware is very convenient for developers. While web users browse on the internet, many ads can appear on computer screen. Some clicked advertisements can redirect to criminal servers that may inject Rezm ransomware on the operating system to begin its operations.
Rezm ransomware will scan through victim’s computer to locate valuable files. Developers will corrupt target files and encrypt it using a complex algorithm. The file extension .rezm will then be added on every infected file. For example, myimage.jpg will become myimage.jpg.rezm after the encryption. A ransom note _readme.txt will drop on every affected folders containing instructions and ransom demand of developers to recover the corrupted files.
This Rezm ransomware is really a threat to victims because once cyber criminals get hold of the important files, no security programs or system can restore the data. Since it is a ransomware, victims should pay a ransom fee in order to bring back the files. Unluckily, only Rezm developers can provide the decryption tool or solution. For some worst instances, even victims pays up the ransom fee, there is no assurance that Rezm operators will deliver those snatched files back.
