Syrk ransomware removal instructions
What is Syrk?
Syrk is another ransomware that was discovered by Leo. It encrypts user's data, creates a text file named "Readme_now.txt" and displays a pop-up window with a ransom note in it. This ransomware renames encrypted files by adding ".Syrk" extension to their filenames. For instance, it renames a file named "1.jpg" to "1.jpg.Syrk" and so on. It also disables Task Manager, in other words, it prevents user's from stopping its malicious process.
As stated in the ransom note (pop-up window), Syrk encrypts photos, videos, documents and other files. The only way to recover them is to contact cyber criminals using the firstname.lastname@example.org and send them the appointed ID number. This ID can be viewed by clicking the "Show My ID" button at the bottom of the pop-up window. When contacted, cyber criminals should send further instructions on how to make a payment (purchase a decryption key). Victims are encouraged to buy it as soon as possible because Syrk will start deleting various files (files in the Photos folder, files placed on a Desktop, files in the Documents folder and so on). According to the ransom note, files will be deleted each time the displayed timer runs out. Research shows that these cyber criminals are not bluffing, Syrk really starts to deleting files that are placed in the aforementioned folders. The price of a decryption key is unknown, however, we do not recommend to trust Syrk developers and pay them for it. There are many cases where people who paid cyber criminals got scammed (did not get the promised decryption tools or keys). In this case the only free and reliable way to recover files is to restore them from a backup. Most ransomware-type programs perform encryptions that are impossible to 'crack' or decrypt without the tools (in this case decryption keys) that only cyber criminals who designed the ransomware have.

There are many different ransomware-type programs (for example, Mogranos, Nqix and .infected), however, most of them are designed to prevent people from accessing their files (encrypt their data) and create or display ransom notes. As a rule, most common (and main) differences are two: price of a decryption and encryption algorithm (symmetric or asymmetric) that is used to block the access to files. That is the biggest problem with most programs of this type is that it is impossible (or almost impossible) to decrypt files without interference of their developers. In other words, cyber criminals usually are the only ones who can help their victims with that. In some cases it can be avoided, but only if the program is not fully developed, has bugs, flaws, etc. Typically, people can avoid data and financial loss if they have their data backed up. For this reason we recommend to create backups regularly and store them on remote server or unplugged storage device.

How to protect yourself from ransomware infections?
Be careful with various attachments or website links that are presented in emails sent from unknown, suspicious email addresses. If you suspect that a received email is irrelevant, then do not open the included attachment or click the presented link. Download software using only direct links and trustworthy, official sources. It means avoid using various third party downloaders, installers, unofficial websites or other untrustworthy, questionable tools for that. It is known that these sources can be (and often are) used to promote/distribute rogue applications that are capable of causing computer infections or some other problems. Update installed software (or operating system) using tools or implemented functions that are provided by official software developers only. Software cracking tools should not be used. To use them is a cyber crime, besides, these tools often install malicious programs instead of the expected software updates. To have a reputable anti-virus or anti-spyware suite installed and keep it enabled at all times is also important. Tools of this type usually detect computer infections before they can do any damage to the system. If your computer is already infected with Syrk, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Update August 22, 2019 - After a number of analysis performed by various malware researchers there's a number of notes that must be made:
- Cyber criminals are distributing Syrk ransomware by disguising it as a hacking tool for Fortnite PC game. The tool supposedly provides aimbot functionality and allows to see where the enemies are. Now the Fortnite PC game is a very popular and has over 250 million active players. Therefore, disguising malware as a hacking tool is very effective, as a lot of players aren't honest and use various illegal/third party tools to ease the gameplay, and improve their score. One of the known malicious executables is named "SydneyFortniteHacks.exe".
- This ransomware is designed to change disable User Account Control (UAC) and Windows Defender by modifying Windows Registry.
- Syrk is based on another high-risk ransomware called Hidden-Cry.
- Syrk is an open-source ransomware.
- This malware is designed to inject itself into existing USB drives (to achieve this, Syrk employs LimeUSB_Csharp.exe tool).
- Syrk ransomware targets the following file formats:
.avi, .bmp, .doc, .docx, .gif, .ico, .jpg, .mov, .mp3, .mp4, .pdf, .php, .png, .ppt, .pptx, .psd, .rar, .sln, .txt, .wav, .xls, .xlsx, .zip
- Syrk ransomware deletes files only from the following folders (in the listed order):
- This ransomware is decryptable! Syrk stores the decryption key locally, in the infected machine. This means that users can easily access it and restore everything without paying. The necessary files are listed below (note that these files are generated only after clicking "Show My ID" button in the pop-up window and they are hidden, therefore, you have to enable hidden file view setting):
- \Users\Default\AppData\Local\Microsoft\-i+.txt (file containing victim's ID)
- \Users\Default\AppData\Local\Microsoft\-pw+.txt (file containing the decryption key a.k.a. password)
- \Users\Default\AppData\Local\Microsoft\+dp-.txt (file containing both ID and password, which is sent to developers' email address)
- This ransomware is designed to perform a "cleanup" operation once a decryption key is entered. After infiltrating the system Syrk generates "Delete.exe" file and executes it once password is entered. This executable deletes the following files:
