Iotr Ransomware is a data locker malware and a variant of Stop/Djvu group. It encrypts files on the targeted PC by adding “.iotr” file virus extension to all files. For example, the file “monthlyreport.xls” will get changed after the ransomware attack into “monthlyreport.xls.iotr”. It will be an encrypted version of the original file and cannot be opened without the decryption key.
After the encryption of files, it leaves a note “_readme.txt” in all compromised folders. This note contains a ransom demand and instructions to unlock the files. Attackers demand $980 as ransom money to provide decryption tools. This guide can help you delete this virus and restore your files without paying the ransom money.
What is Iotr Ransomware?
Iotr Ransomware is another recently found ransomware-type malware infection that belongs to STOP/DJVU family. This dubious threat is a new variant of a long-lasting file-encrypting virus that uses a powerful algorithm to encode files on the infected computer. The primary motive of the creators of this virus is to extort money from users in return for the decryption tool.
Iotr File Virus is able to attack all versions of Windows computers without users’ permission. Upon infiltration, it runs a powerful encryption algorithm to lock all the personal files of the victim. After encoding files, it also leaves a ransom note “_Readme.txt” on the infected system to ask for the ransom money. This dubious virus scares users by saying that their files can only be unlocked by the decryption tool. All the files on the targeted PC will become useless and a copy of the ransom note can be found in every folder.
Encryption of Data on infected PC
Iotr Ransomware basically performs asymmetric encryption on a compromised PC using powerful military-grade encryption software that generates a unique decryption key for every computer. These unique keys are stored on a remote server and are vital for the restoration of encrypted files. There is no way to access files encrypted by Iotr file virus without that key. Needless to say that every PC needs its own key to unlock files. This nasty virus can encrypt all types of files like videos, images, audio, documents, database, or almost every file typically stored on a personal computer.
If you store important and sensitive documents on your PC then you must keep a backup of your files on any external USB drive or cloud drive. Because once your system is infected by a threat like this, then it could be a very serious problem. Most of the time, encryption like this is unbreakable or sometimes files also get corrupted. To avoid losing any important documents it is highly recommended to make backup copies.
Iotr File Virus and decryption of files
The decryption of files encrypted by Iotr File Virus completely depends on obtaining the decryption key. Although attackers are offering the decryption tool for a price which might be the easiest way to restore your data. But you can’t trust cyber criminals to keep their word once they get paid. They will have no motivation whatsoever to decrypt your files. It completely depends on their morals if they want to give you a decryptor or not, once you pay the price. However, we strongly advise victims to not pay ransom money to avoid any scam.
In fact, we have got many reports where victims did not get the decryption tool after paying the money. Your computer is already infected by Iotr file virus, all your files are encrypted and you should not risk your money too. Cybercriminals are only interested in financial benefits and they might re-encrypt your files by releasing new variants. If they once get money from you, they can also attack your system again to make more money.
Ransom Note “_readme.txt” is left on PC
As we have already mentioned, after encrypting your files, Iotr Ransomware will leave a ransom note on your computer. It is the standard practice of all file-encrypting malware to extort money from victims. You can also find that ransom note in all the compromised folders. This note contains a text message claiming that there is no other way of restoring files. Attackers will also offer free decryption of 1 file as proof and ask users to pay the price to decrypt all files.
The base price of the decryptor for .Iotr Ransomware is set at $980. Makers of this virus are offering a 50% discount if victims will pay the ransom money within 72 hours. They suggest users take the deal and pay $490 USD through Bitcoin. Victims are said to contact virus creators through emails provided in the ransom note to get the decryption tool.
Ransom note (_Readme.txt) contains the following text message :
