How to remove Tomas Ransomware and decrypt .tomas files

What is Tomas Ransomware

Tomas is a high-risk threat, classified as ransomware, that belongs to Oled-Makop family. Using special algorithms, infections of such type encrypt personal data and demand money from victims. Tomas is not an exception, it targets various kinds of data including images, videos, text files, and other valuable sorts. When Tomas appears on your system, it disables protectionary services and activates the encryption of data. During the process, the virus changes the stored files beyond recognition. For instance, a file like 1.mp4 will be changed using a long string of symbols like this 1.mp4.[E3CEFA3F].[tomasrich2020@aol.com].tomas. This model consists of the original filename, personal ID, cybercriminal’s email address, and the .tomas extension to finish. After the process is done, Tomas creates a note called readme-warning.txt that states how to decrypt your data.

Cybercriminals are trying to wind you down after such a big loss saying that your files can be decrypted. The only thing required to do is buying a decryption key that may cost you over a monthly salary – approximately 3000 dollars, which are accepted only in Bitcoin. In case you linger the payment, the amount will be doubled. One of the victims paid the required fee and got lucky to receive the keys. In reality, this is a huge risk to trust suspicious figures without significant proves. This is why we recommend you delete Tomas Ransomware and recover your data from a backup location if one was created before the attack. You can also try to use third-parties tools in our guide below, but they may not guarantee the result you want.

How Tomas Ransomware infected your computer

The victim we mentioned earlier also said that he was penetrated via RDP (Remote Desktop Connection), which is used to access computers remotely over a network connection. Extortionists tend to exploit unprotected RDP configuration to hack the server and spread malware like Tomas. This is only one way of how ransomware can be distributed over users, there are plenty of others that include e-mail spam with malicious attachments, keyloggers, backdoors, trojans, fake software cracking tools, and untrustworthy downloads. As you can see, distribution channels surrounding us on the web are abundant. Your own responsibility is to stay away from unfamiliar content imposed by third-parties figures.
