ROGER ransomware removal instructions

What is ROGER?

Discovered by Jakub Kroustek, ROGER is a malicious program, belonging to the Crysis/Dharma ransomware family. It operates by encrypting data and demanding payment (ransom) for decryption tools/software. During the encryption process all affected files are renamed with victim's unique ID, developers' email address and the ".ROGER" extension. For example, a file - "1.jpg" would appear as something similar to "1.jpg.id-1E857D00.[backdata.company@aol.com].ROGER". Once this process is finished, a text file titled "FILES ENCRYPTED.txt" is created on the desktop and a pop-up window is displayed. Updated variants of this ransomware use ".[admin@datastex.club].ROGER" extension for encrypted files.

The message in the text file states that all of the victim's data has been encrypted. In order to return it to its original condition, users are told to contact the cyber criminals behind this infection - via the email address listed. The text presented in the pop-up window is a more detailed ransom note. It informs users that they must try reach ROGER's developers through the web-link given. This link can only be opened with the Tor browser. Should their attempts at establishing communication yield no results within twelve hours, victims must contact the developers using the email address. The note ends with warnings, which instruct users not to rename the compromised files and/or try decrypting them with third party software - as that can lead to permanent data loss. In most cases of ransomware infections, manual decryption (i.e. without the involvement of the criminals behind the malware) is impossible. Typically, only the program used for the encryption is capable of breaking it. However, it is expressly advised against contacting and/or meeting the demands of cyber criminals. Often, despite paying, users do not receive the necessary tools and their data remains encrypted, which makes it essentially worthless.To prevent ROGER from further encryptions, it must be removed. Unfortunately, removal will not restore already encrypted data. It can be recovered from a backup, provided if one was made prior to the infection and stored in a separate location.

ROGER decrypt instructions

All ransomware is designed to encrypt files and demand a ransom to be paid. These infections differ form one another by the cryptographic algorithm (symmetric or asymmetric) used for the encryption and by the payment size. Usually, ransoms vary between three and four digit sums (in USD). Common currencies include various cryptocurrencies, pre-paid vouchers and other digital currencies, they are chosen due to transactions of such being difficult/impossible to trace. Unless a ransomware is still in development and/or has certain flaws/bugs - decryption with third party software is not a viable option. SaveTheQueenCalumSpartCryptMarioLocker are a few examples of other malware, under the same classification as ROGER. To ensure data safety, it is recommended to keep backups in unplugged storage devices and/or remote servers. Preferably, multiple backup copies should be stored in several different locations.

How did ransomware infect my computer?

Trojans, spam campaigns, untrustworthy download channels, software "cracking" (activation) tools and fake updaters - are the primary proliferation methods of ransomware and other malware. Trojans are malicious programs, capable of causing chain infections (i.e. they download/install additional malware). Large scale spam campaigns are used to send deceptive emails, containing infectious files (or links leading to them). These letters are rarely suspicious, they are frequently disguised as "official", "important", "urgent" and similar priority mail. The attachments come in a variety of formats (e.g. archive and executable files, PDF and Microsoft Office documents, JavaScript, etc.), once they are opened - it triggers them to start infecting the system. Untrustworthy download channels, such as: P2P sharing networks (BitTorrent, eMule, Gnutella, etc.), unofficial and free file-hosting sites, third party downloaders and the like - are more likely to offer malicious content disguised as regular programs and/or ordinary software bundled with it. Instead of activating licensed products, "cracking" tools can cause infections. Fake updaters exploit weaknesses in outdated programs and/or simply install malware, rather than the promised updates.

How to protect yourself from ransomware infections?

Users are advised against opening dubious and/or irrelevant emails. All attachments (and links) found in suspect mail must never be opened, as they are the source of a potential infection. It is recommended to only use official and verified download channels, as opposed to sharing networks and other third party downloaders. Programs should be activated and updated with tools/functions provided by legitimate developers. Illegal activation tools ("cracks") and third updaters should not be used, due to risk of malware installation. It is paramount to have a dependable anti-virus/anti-spyware suite installed and kept updated. Furthermore, this software should be used to perform regular system scans and removal of detected threats/issues. If your computer is already infected with ROGER, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Text presented in ROGER ransomware's pop-up window:

YOUR FILES ARE ENCRYPTED
Don't worry,you can return all your files!
If you want to restore them, follow this link:zombietry4o3nzeh.onion/?ticket=Rt31ws32vJLxvwudeH_1E857D00
Use Tor Browser to access this address.
If you have not been answered via the link within 12 hours, write to us by e-mail:backdata.company@aol.com
Attention!
Do not rename encrypted files.

Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.

4. In the opened window, click "Next".

restore system files and settings

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the ROGER ransomware virus infiltrating your PC).

select a restore point

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 ROGER 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 ROGER 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 ROGER, 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 ROGER 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, and 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.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
