First of all, it is stated your network has been hacked, which allowed extortionists to encrypt your data. Then, cybercriminals say they are the only figures able to perform secure and complete decryption of data. For this, victims are asked to establish communication using the Tor browser link and pay for decryption software. The price is kept secret and depends on how fast you contact developers. After completing the payment, developers promise to send a unique decryption tool to regain the data. In addition to that, ransomware developers say they can decrypt several files (that do not contain valuable information) prior to paying the ransom for free. This is a good offer indeed, but still insufficient to trust cyber criminals on an individual basis. There have been many cases when no decryption tools end up received by victims even after paying the ransom. Although this is by far a risk, cybercriminals remain to be the only figures able to unlock your data completely. There are no third-party tools that could guarantee 100% decryption of Tohnichi files just yet. At this moment, the best way to avoid paying the ransom is using backup copies. You can use them from external devices to restore data after deleting the virus. In case there are no such available, you can still give it a try via third-party tools, but note that it can damage your data. All the necessary information on virus removal as well recovery options can be found below.

How Tohnichi Ransomware infected your computer

Most often, ransomware infections distribute via malicious e-mail spam letters, trojans, unprotected RDP configuration, botnets, keyloggers, backdoors, malicious ads, untrustworthy downloads, fake updates, or programs, and so much more. Usually, users get caught after opening malicious files inside of spam letters. These files are often .DOCX, .PDF, .EXE, .XLSX, .ZIP, .RAR, or .JS formats concealing the virus. On the initial basis, these formats have nothing to do with malicious content, but yet they are exploited by frauds to cover various malware. As a result, users that open such files from fake messages risk getting infected with ransomware, for instance. To avoid this in the future, it is important to think twice before initiating some content from unknown figures. Even your friend could be hacked and abused to send malicious content. If you are unable to grant protection yourself, it would be worth taking advantage of special tools helping to do it for you.
