What is Udacha Ransomware

Udacha is a ransomware virus that encrypts data with AES+RSA algorithms and demands payment of 490$ (0.013 BTC) in order to return it. This information is visible inside of the ReadMe_Instruction.mht file, which is created after encryption puts its finishing touches onto the data. Prior to this, however, users will see their files changed with the .udacha extension. To illustrate, a file like 1.pdf will change to 1.pdf.udacha and reset its shortcut icon. Below, you can see the full information that is written within the ransom note.

Cybercriminals say buying decryption software is the only way to recover your files as they are the only figures able to share unique keys that will access your data. Therefore, victims are requested to send 490$ in BTC to the crypto wallet of malware developers and notify about completed payment via e-mail (udacha123yes@mail2tor.com) or Telegram channel (@udacha123yes). Unless this request is met during the first day of infection, the price will be doubled immediately. Before buying the proposed software, victims can send 1 file to the extortionists to have it decrypted for free. Such a promotion is meant to uplift the trust of swindlers in the eyes of desperate victims. In addition to this, Udacha developers also inform you against manipulating files with third-party tools or manual actions as it may damage their configuration forever. This is true, especially when ransomware uses advanced algorithms and stores the assigned keys on online servers. For this reason, the best and most secure way to recover your data is via backup copies.

It is important to perform the removal procedure to prevent further encryption of data. Below, you will find all the necessary information regarding virus deletion and restoration of data.

How Udacha Ransomware infected your computer

Ransomware infections may crawl into your systems in multiple ways. For instance, the majority of malware developers like to use malicious attachments within e-mail spam letters. They do it by disguising such messages as part of legitimate firms like DHL, DPD, FedEx, and other popular names. Unfortunately, many users do not suspect that something is wrong with the message they received in their inbox. It tells you some fabricated story to push into downloading and executing the attached files. As a rule, people are likely to be infected after opening files from MS Office like Word or Excel. This is because cybercriminals can substitute their configuration with scripts that install malicious software. The same technique can also be done with links promoted in similar letters. They oftentimes lead to download pages asking to install some piece of software. Apparently, this is a trap meant to inject a virus into your system. To avoid this and many other channels like trojans, backdoors, keyloggers, fake updates or software, hacks via unprotected RDP configuration, botnets, web-injects, and malicious ads, – it is important to run careful and safe activity around the web.
