What is IS ransomware?

IS (also known as Ordinypt) ransomware was discovered by dnwls0719. IS is a malicious program which prevents victims from accessing their files, it does this by encrypting them with a strong encryption algorithm. As a rule, to recover their files victims must pay cyber criminals a ransom. IS adds the same random extension to the filenames of all encrypted files, for example, it renames "1.jpg" file to "1.jpg.KRk5p", and so on. Instructions on how to pay a ransom are provided in the text "KRk5p_how_to_decrypt.txt" text file. Its name depends on the extension of encrypted files.

To purchase a decryption software victims must to use Tor browser and open the link which is provided in the ransom note. In the Tor website victims must enter an access code that can be found in the ransom note too. After that Tor website opens another page which displays a countdown timer, it shows the amount of time that victims have to pay a ransom. When the timer runs out, decryption keys will be deleted and victims will not be able to decrypt their files/purchase a decryption key anymore. The price of decryption software and keys is $1,500, it must be paid in cryptocurrency (Bitcoins). Cyber criminals assure victims that they will send them decryption tools after payment and that there is no one else who can provide those tools. Unfortunately, the second part is true: most ransomware-type programs lock files using strong encryption algorithms and it is impossible to decrypt encrypted files without the right tools that only cyber criminals who designed ransomware have. However, quite often cyber criminals do not send those tools even after a payment, people who trust them often get scammed. Typically, the only way to recover files for free (and without having to contact or/and pay ransomware developers) is to restore them from a backup.

IS decrypt instructions

IS ransomware is similar to other programs of this type, some examples are Hermes837, Guarded and NextPharma. In most cases these programs encrypt files using cryptographic algorithms (symmetric or asymmetric) and create ransom notes that contain instructions on how to pay a ransom. Typically, the main and most common differences are algorithms used for encryption and size of a ransom. Either way, most of the times it is impossible to decrypt files without interference of cyber criminals, unless ransomware is not finished (has bugs, flaws, etc.). That is why it is always a good idea to have data backed up and store in on a remote server (like Cloud) or/and unplugged storage device.

How did ransomware infect my computer?

Typically, cyber criminals spread ransomware (and other malware) through spam campaigns, unreliable download channels/tools, Trojans, unofficial software updating and/or activation tools. Quite often they send emails that contain attached files (or links) and hope that at least some of the recipients will open them. If opened, these files usually install one or another malware. Typically, they send Microsoft Office documents, PDF documents, executable files (like .exe), JavaScript files, archives like ZIP, RAR, etc. Another way to spread malware is to use untrustworthy file or software download channels. Examples of such channels/tools are Peer-to-Peer networks (torrent clients, eMule and so on), unofficial pages, third party downloaders, freeware and free file hosting pages. People who download files using them risk to download malicious files that, if opened (executed), install high-risk malware. Typically, cyber criminals disguise these files as harmless and legitimate. Trojan is a type of malicious software that usually is designed to cause chain infections. In other words, if a computer is infected with a Trojan, then it gets infected with additional malware. Unofficial (third party) updaters are often designed to install malicious software instead of updating installed one, or exploit bugs, flaws of outdated software that is installed on the system. Unofficial software activation ('cracking') tools are used by people who seek to avoid paying for a licensed software. However, these tools are often designed to spread malware and people who use them install malicious programs by themselves.

How to protect yourself from ransomware infections?

We recommend to avoid opening files that are attached to irrelevant emails, especially when they are sent from unknown, suspicious addresses. Typically, cyber criminals disguise such emails as official, important, legitimate, and so on. All installed software should be downloaded from official websites and using direct download links. None of the other tools/sources that we mentioned in the previous paragraph are safe to use. Software 'cracking' tools and unofficial, fake software updaters often download and install malicious programs instead of activating of updating installed software or operating systems. Besides, unofficial activation tools are not legal. One more important thing is to have a reputable anti-virus or anti-spyware tool installed and scan the system with it regularly. If your computer is already infected with IS, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining IS ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of IS are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by IS, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.
