Yyto ransomware developers dream of cutters?

Yyto virus happens to be a file-encrypting threat. Though the malware is still under investigation, it is likely to use AES-256 algorithm to encode users’ personal files and attach .YYTO file extension.[1] The cyber criminals did not spend too much time on developing this virus: it does not open its GUI, it only opens up its help_to_decrypt.txt file where further instructions are provided.

Unlike other crypto-malware, it refers to an .onion link which leads to TorBox. According to the information provided on its homepage, it is a secret email domain designed for communication and separated from the public net. It should ensure the anonymous connection between a perpetrator and a victim.

Furthermore, users should contact the cyber criminals via cutterswish@torbox3uiot6wchz.onion. They warn netizens to use only the specified tool. Otherwise, the hackers will not respond nor transfer the decryption key. It does not indicate how much victims should transfer to recover the files. In any case, there are too many unanswered questions whether the perpetrators return the files, thus, proceed to Yyto removal. For that purpose, you may use Reimage or Malwarebytes Anti Malware.

The picture illustrating Yyto ransom note

Even though the majority of crypto-malware function the same and possess the same technical specifications, there are slight differences among them. Thus, Yyto malware contains minor peculiarities.

Usually, perpetrators provide Tor or Bitcoin wallet address for collecting ransoms. In this case, the authors behave differently. Instead, they opt for Torbox. IT specialists warn not to remit payments.[2] Naturally, we can assume that technical difficulties may occur when victims transfer the transactions to the authors of the latter malware. Instead of considering to comply with the demands, make another choice – remove Yyto virus.

Transmitting the malware

Despite dozens of written articles about Yyto ransomware and their distribution ways, spam emails remain the most popular method for transmission. Ransomware executable are wrapped into .zip folder and presented as supposed invoice or package delivery information.

Speaking of which, the virus also disguises its executable in 2.exe file. Note that the trojan which may be identified as TR/Crypmodadv.tuglz, Win32.Trojan.WisdomEyes.16070401.9500.9945, or Spyware (004c76c01) delivers Yyto hijack payload as well. Thus, mere vigilance is not sufficient in securing your computer and personal data from virtual threats. Install an anti-virus and anti-spyware tools to fortify the protection.

Yyto ransomware termination procedure

The problem with this malware is that you may not spot it right away as it disguises its processes and does not launch its specific GUI. It is understandable if you may follow the proposed scenario by the hackers in the pursuit of retrieving the files. On the other hand, if you have backup copies, there is no need to comply with the demands.
