What is IS ransomware?

IS (also known as Ordinypt) ransomware was discovered by dnwls0719 and is a malicious program that prevents victims from accessing their files by encoding them with a strong encryption algorithm. To recover their files, victims are encouraged to pay a ransom to the cyber criminals. IS adds a random extension to the filenames of all encrypted files. For example, "1.jpg" might become "1.jpg.KRk5p". Instructions about how to pay the ransom are provided in the "KRk5p_how_to_decrypt.txt" text file. The name of this file is associated with the extension of encrypted files.

To purchase decryption software, victims must to use the Tor browser and open the link, which is provided in the ransom message. On the Tor website, victims must enter an access code that can also be found in the ransom message. The Tor website then opens another page, which displays a countdown timer giving the time remaining within which victims must pay the ransom. When this time elapses, decryption keys are deleted and victims will no longer be able to decrypt their files or purchase a decryption key. The cost of decryption software and keys is $1,500 and must be paid in a cryptocurrency (Bitcoins). Cyber criminals assure victims that they will send decryption tools after payment is made, and that no other party can provide these tools. Unfortunately, the second part is accurate: most ransomware-type programs lock files using strong encryption algorithms and it is impossible to decrypt encrypted files without specific tools held only by the cyber criminals who designed the ransomware. Note, however, that cyber criminals often do not send these tools even after payment, and people who trust them are scammed. Typically, the only way to recover files free of charge (and without having to contact and/or pay ransomware developers) is to restore them from a backup.

IS decrypt instructions

IS ransomware is similar to other programs of this type. Other examples are Hermes837, Guarded, and NextPharma. In most cases, these programs encrypt files using cryptographic algorithms (symmetric or asymmetric) and create ransom messages that contain instructions about how to pay the ransom. Common differences are algorithms used for encryption and size of ransom. In any case, it is often impossible to decrypt files without the involvement of cyber criminals, unless ransomware is not finished (has bugs, flaws, etc.). Therefore, have your data backed up and store it on a remote server (Cloud) and/or unplugged storage device.

How did ransomware infect my computer?

Typically, cyber criminals proliferate ransomware (and other malware) through spam campaigns, dubious download channels/tools, Trojans, unofficial software updating and/or activation tools. They often send emails that contain attached files (or links) and hope that at least some of the recipients open them. If opened, these files then install malware. Typically, they send Microsoft Office documents, PDF documents, executable files (.exe), JavaScript files, and archives such as ZIP, RAR, etc. Malware is also spread using 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 downloading malicious files. If opened (executed), these install high-risk malware. Typically, cyber criminals disguise these files as harmless and legitimate. A Trojan is malicious software that usually causes chain infections. Therefore, if a computer is infected with a Trojan, it becomes infected with additional malware. Unofficial (third party) updaters are often designed to install malicious software rather than updating legitimate installed software, or they exploit bugs, flaws of outdated software installed on the system. Unofficial software activation ('cracking') tools are used by people who seek to avoid paying for licensed software, however, they are often designed to proliferate malware - people who use them end up installing malicious programs.

How to protect yourself from ransomware infections?

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 mentioned above are safe to use. Software 'cracking' tools and unofficial, fake software updaters often download and install malicious programs rather than activating or updating installed software or operating systems. Furthermore, unofficial activation tools are illegal. 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.

Update September 17, 2019 - A new spam email campaign currently targeting German-speaking users and spreading IS (Ordinypt) ransomware has recently been discovered. The spam emails are presented as job applications from a woman who claims to be Eva Ritcher. Emails consist of German text and two attachments: Eva's picture (actually, a random stock photo of a woman) and an archive, which contains a malicious executable presented as Eva's resume in PDF format. At time of research, attachments were named "Eva Ritcher Bewerbungsfoto.jpg" and "Eva Richert Bewerbung and" (the executable within is named "Eva Richter Bewerbung und Lebenslauf.pdf.exe"), however, these filenames might vary.

6. In the opened window, click "Yes".

run system restore

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.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as IS ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
