Fezmm – Ransomware
The Fezmm stands for a ransomware-type infection. Fezmm was elaborated specifically to encrypt all major file types. When the file is encrypted people are not able to use them. Fezmm adds the “.fezmm” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Fezmm, will be renamed into “myphoto.jpg.fezmm“. As quickly as the encryption is completed, Fezmm places a special text file into every folder containing the encrypted data.The message given by Fezmm text file requesting for the ransom is definitely the same as the statements given by other ransomware representatives. It literally points out that the information is encrypted and that the only way to restore it is to use a a distinct decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism applied by Fezmm is still not appropriately examined. Still, it is definitely particular that each victim may be given the specific decryption key, which is absolutely distinct. It is difficult to restore the files without the key available.
Another trick of Fezmm is that the victims cannot gain access to the key. The key is kept on a particular server run by the frauds associated with Fezmm ransomware. To get the key and recover the important information people have to pay the ransom.
Fezmm encrypted your documents, but that might not be the only damage done to you. The ransomware might still be hidingon your computer. To identify whether this holds true, we suggest downloading GridinSoft Anti-Malware.

Nonetheless, irrespective of the asked for amount, people should keep away from paying the virus. Cyber frauds are unfair, so they tend to totally ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom generally does not provide any positive result and people just waste their money for nothing.
We highly advise that you do not contact these crooks and certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Fezmm ransomware and to recover the data data totally free. Hence, the only best decision is to recover the lost data from the available backup.

Keep in mind that the internet is now overwhelmed with threats that look comparable to Fezmm ransomware. Harmful programs of such kind are usually elaborated to encrypt important information and to set forth the demand prior to the user to pay the ransom. The peculiarity of all such ransomware threats is that all apply a comparable algorithm to generate the unique decryption key for files decryption.
Hence, as long as the ransomware is still being developed or has some hidden bugs, by hand recovering the information is merely not feasible. The only way to avoid the loss of your crucial information is to regularly create backups of your important information.
Bear in mind that even if you create such backups, they need to be put into a special storage utility not connect to your main PC. You may use the USB Memory Stick or external hard drive for this purpose, or refer to the help of the cloud storage. If you keep your backup files on your common system they may be encrypted in addition to other files, so it’s definitely not a good storage location.
How did ransomware infect my system?
There are numerous ways used by online frauds to distribute Fezmm ransomware. Even though it is uncertain how exactly Fezmm injects your system, there are some leaks through which it may infiltrate the system:
- integration with third-party software, especially freeware;
- spam emails from unidentified senders;
- websites rendering free hosting services;
- pirated peer-to-peer (P2P) downloads.
Often Fezmm ransomware may exist as some genuine software, for example, in the pop-ups instructing users to implement some crucial software application updates. This is the common technique used by online scams to persuade people into downloading and installing Fezmm infection manually, by means of their direct participation in the installation process.
Furthermore, the criminals might describe various email spam methods to inject destructive codes into Windows PC. So, they may refer to to sending unsolicited spam emails with tricky notices promoting users to download the attachments or click on certain download links, for example, the ones motivating users to open some video, documents, tax reports or invoices.
Needless to mention, opening such files or clicking on such dangerous links may severely damage the PC. Fictitious Adobe Flash Player update notifies may result in Fezmm virus injection. As for the cracked applications, these illegally downloaded programs may also contain destructive codes resulting in Fezmm secret installation. Finally, injection of Fezmm may take place by ways of Trojans that privately get injected into the system and install destructive utilities without the user’s consent.
