Sorry ransomware removal instructions

What is Sorry?

Sorry is a ransomware-type virus discovered by malware security researcher, Karsten Hahn. Research shows that Sorry is based on an open-source ransomware project called Hidden Tear. Immediately after infiltration, Sorry encrypts stored data using AES cryptography and appends filenames with the ".sorry" extension (e.g., "sample.jpg" is renamed to "sample.jpg.sorry"). Note that there is also another ransomware infection called Purge (Globe) that uses the same extension. Once files are encrypted, using them becomes impossible. Following successful encryption, Sorry creates a text file ("How Recovery Files.txt") and places a copy in every existing folder.

The new text file informs victims of the encryption and encourages them to contact Sorry's developers to restore their data. As mentioned above, Sorry uses AES - a symmetric encryption algorithm. Therefore, each victim has a personal key used to encrypt and decrypt files. Once files are encrypted, this key is sent to a remote server controlled by Sorry's developers. This gives cyber criminals an advantage - they can blackmail victims. After contacting these people, victims are asked to pay a ransom in exchange for release of their  keys. The cost is currently unknown, however, ransomware developers typically demand $500-$1500 in Bitcoins (or other cryptocurrencies). These people can never be trusted - research shows that cyber criminals often ignore victims once payments are submitted. Therefore, paying typically gives no positive result and users are scammed. As well as losing their money through this scam, victims will support cyber criminals' malicious businesses. For these reasons, we strongly advise you to ignore all requests to contact these people or submit any payments. Unfortunately, there are currently no tools capable of restoring files encrypted by Sorry free of charge. Therefore, the only solution is to restore everything from a backup.

Sorry is virtually identical to Rapid 2.0, L0cked, Stinger, Zenis, and dozens of other ransomware-type viruses. Note that, although these viruses are developed by different cyber criminals, their behavior is virtually identical - all encrypt data and make ransom demands. In most cases, these viruses have just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Research shows that, unfortunately, most employ algorithms that generate unique decryption keys. Therefore, unless the malware is not fully developed or has certain bugs/flaws (e.g., the key is hard-coded, stored locally or similar), decryption without involvement of the developers (not recommended) is impossible. Ransomware presents a strong case for maintaining regular data backups, however, it is very important to store backup files on a remote server (such as cloud) or an unplugged external storage device. If not, the malware will encrypt them as well.

How did ransomware infect my computer?

Ransomware-type viruses are proliferated in various ways, however, the most popular five are: 1) spam emails [malicious attachments]; 2) P2P [peer-to-peer] networks; 3) third party software download sources; 4) fake software update tools, and; 5) trojans. Infectious attachments typically come in the format of JavaScript files or MS Office documents. Once opened, these files execute scripts that stealthily download and install malware. P2P networks (eMule, torrents, etc.) and other unofficial download sources (free file hosting websites, freeware download websites, etc.) present malware as legitimate software. Therefore, users are tricked into downloading and installing malware, whilst fake software updaters infect the system by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than software updates. Trojans are the simplest of all - they merely open "backdoors" for other high-risk malware to infiltrate the system. In any case, the main reasons for computer infections are poor knowledge and careless behavior.

Threat Summary:
NameSorry virus
Threat TypeRansomware, Crypto Virus, Files locker
SymptomsCan't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.
Distribution methodsInfected email attachments (macros), torrent websites, malicious ads.
DamageAll files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.
Removal

To eliminate Sorry virus our malware researchers recommend scanning your computer with Spyhunter.

How to protect yourself from ransomware infections?

The key to computer safety is caution. Therefore, be very cautious when browsing the Internet. Think twice before opening email attachments. If emails are sent from suspicious/unrecognizable addresses and attachments seem irrelevant, immediately delete these emails and certainly do NOT open any attached file. Furthermore, we advise you to download your applications from official sources only, using direct download links. Third party download/installation tools are typically monetized by promoting rogue apps, and thus should never be used. Keep installed applications updated and have a legitimate anti-virus/anti-spyware installed and running at all times. Remember, however, that criminals proliferate malware via fake updaters and, therefore, apps should be updated using implemented functions or tools provided by the official developer only.

Step 2

Log in to the account infected with the Sorry virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.

If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.

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 Sorry 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 Sorry 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 Sorry 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 files encrypted by Sorry, 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 Sorry 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.

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