Turkish HiddenTear-based Executioner continues causing trouble
Executioner virus (alternatively known as Cellat malware) functions as ransomware created on the basis of HiddenTear[1]. Interestingly, the malware is of Turkish origin. However, there is no need to understand the language to grasp the basic meaning: the ransom note informs that all files photos, documents, and other important documents are encrypted.
Furthermore, the original version of the threat appended random file extensions to the affected files. Nonetheless, the latest version attaches the extension indicating a random set of 6 characters and numbers. No specific information about the used encryption method is presented. Besides its main ransom text, the malware also leaves the HTML link, Sifre_Cos_Talimat.html, on a local folder.
It contains the text in English informing victims that their files have been encoded. In order to purchase the decryption software, Executioner Decrypter, affected users should contact the perpetrator via executioner.ransom@protonmail.com or executioner.ransom@bk.ru.
They should purchase the amount of bitcoins even to 150 dollars. For that purpose, the malware indicates the bitcoin address. Let us remind you that HiddenTear free decryption tool is available on the web, so it would be wiser to proceed to Executioner removal. FortectIntego or MalwarebytesMalwarebytes makes this process much faster. Luckily, IT specialist has found a way how to decrypt files. The tool also works with the latest edition.
Many might question why HiddenTear pattern has not been still removed from the web. Its availability enables crooks of various ilk to engage in the illegal activities of ransomware programming. On the other hand, programming the malware according to this pattern also increases the chances of decryption. Executioner malware manifests that the developer has higher than the basic programming skills.
The virus is set to attach different file extensions which trouble the detection of the malware on time. Furthermore, unlike the majority of HiddenTear based threats, the threat does not display a .txt file with instruction but rather Sifre_Cos_Talimat.html website link. It asks you to visit two onion website links for supposed instructions.
After entering them, you are redirected to the domain called “Executioner” in both, Turkish and English, with the USA and Turkish flags. It also contains transparent video icon and below link suggesting to have some fun. Naturally, these links may contain another portion of the ransomware. Further sections will explain how to remove Executioner.
New versions come out, the virus is still decryptable
After the original version made its way through the virtual space, the author has not given up. A new version has been roaming on the wild. However, the developer did not introduce any significant changes. Instead of previous email address, now the malware employs executioner.update@protonmail.com.
Furthermore, the threat generates a random crypto key. In other words, data recovery might be futile. In contrast to the original threat, the infection also appends a file extension comprised of 6 random characters and numbers. Luckily, victims of this EDA2 threat can decode their files for free regardless of which version they are infected with.[2]
Distribution techniques
Before proceeding further, it is crucial to be aware of its distribution channels in order to prevent Executioner hijack in the future. The virus is apt in spreading via spam emails. Its executioner.exe file may be wrapped in a fake delivery email or tax report alert. Do not rush opening any of suspicious links before verifying the sender.
Moreover, it is likely that the virus may have lurked in corrupted video links or torrent files. Note that some hackers even distribute malware in corrupted subtitle files[3]. Thus, keep an attentive look to your Inbox and visited websites and update computer security tool for it to fortify cyber protection as well. Fortunately, numerous cyber security tools can already detect the trojan – Gen:Heur.Ransom.HiddenTears.1.

You may remove Executioner virus with the assistance of an anti-spyware tool. However, it is not surprising if you may encounter system errors. They are likely to be counterfeited by the malware to prevent you from deleting.
In that case, reboot the PC in a Safe Mode and launch a cyber security tool. After that, you will be able to finish Executioner removal. Below instructions, you may find some useful programs which may benefit for data recovery. Try HiddenTear Decrypter as well. Besides Turkish netizens, nearest countries, such as Bulgaria[4], might encounter the threat. Be vigilant and employ different prevention measures.
