This .TCYO File Virus is able to infect any version of Windows PC easily and it can sneak past your antivirus protection without detection. Earlier you won’t even recognize what struck your PC and then suddenly all your files are locked with an undecipherable key.
.TCYO Virus is one of the many variants released by the creators of Dharma Ransomware virus. This dubious malware intrudes on your computer and then executes its malicious encryption software.
All your files get locked with new “.TCYO” extension, following the unique ID assigned to the victim and Email ID of the cyber criminals. For example, if a file on your PC has the name “myphoto.jpg” then it will convert into “myphoto.jpg.id-1E857D00.[firstname.lastname@example.org].TCYO” which cannot be opened without a decryption tool.
After the successful encryption of all the files, A ransom emanding pop-up window is placed on the desktop and a ransom note named as “FILES ENCRYPTED.txt” as text file is dropped in all compromised folders.

What happens to your files
As you know, .TCYO File Virus uses a powerful RSA military-grade encryption algorithm to encode your files. All your files will still be there on your computer, but you will not be able to access them. This kind of encryption algorithm is mainly used to protect files, transmit information without having the tension of anyone intercepting the message. This practice was first used for military and intelligence purposes but now many social media companies like WhatsApp, Viber, Telegram, and others are using end-to-end encryption. This technology keeps all the communication safe from sender to receiver and no one can read the messages.
Such end-to-end encryption, military-grade cipher are good for privacy but in hackers’ hands, it is a weapon of mass destruction. There is no way to break the encryption without a decoder and thus cybercrooks behind .TCYO Virus Ransomware gets away by cheating innocent users. All these files encrypted by this malware can only be decoded by a private decryption tool and key which is unique for every computer. Brute forcing to restore files to the original version might corrupt the whole and even the decryption tool won’t even recover .TCYO encrypted files.
However, there are some ways to recover files infected by this virus. It will not be easy but it could be possible to recover most (if not all) of the files without paying money to hackers. Sometimes ransomware creators also leave some flaws which could be exploited to create a decrpytor. Unfortunately, there is no free decryptor yet found for .TCYO Virus Ransomware. But it does not mean it’s not going to happen, however, it may take time. You can also recover your files through backup or use data recovery software to recover previous versions of your encrypted files.
TCYO Ransomware: Threat Analysis
Do not pay money hackers
Paying ransom money to hackers to get the decryption is not a good idea. Many people might think they cannot risk their valuable information and paying money is the easy way out but it can be dangerous. As you know, .TCYO File Virus is a variant of Dharma Ransomware. There are hundreds of more variants just like this. So if you once pay, your system can get infected again by some other version of the malware.

Firstly, the main thing is you cannot trust cybercriminals to keep their words once they get paid, and secondly, you cannot force them to. So in our expert opinion, you must refrain from paying any money to .TCYO Virus because it will only motivate them to expand their blackmailing business.
