How to remove Skynet ransomware

Skynet ransomware is a malicious program that locks all data on a Windows system and then demands a ransom for its return

Skynet is a ransomware-type virus that infiltrates users' PCs and encrypts all their personal files using a sophisticated encryption algorithm,^[1] making all photos, videos, documents, databases, and other important data unusable (each of the files is appended with a random string of characters, for example, “.br84”). This damage can be really significant to those who had no backups and held important files on their systems.

Cybercriminals behind the attack are well aware of this, that's why they ask users to pay a ransom so that the data can be recovered. They are not willing to giveaway the decryptor for free and are asking to pay in bitcoin, promising a discount of 50% if contacted within 24 hours of the infection.

For communication purposes, hackers provide a contact email ransom.data@gmail.com within a ransom note SkynetData.txt. We strongly recommend avoiding any contact with Skynet virus authors and instead choosing alternative methods of file recovery we cover below.

Skynet virus and how to approach it

Skynet ransomware stems from a rather established malware family known as Chaos – we have already covered numerous of its previous versions, including Ritzer, BlackToxic, Odaku, and a few others. It was originally derived from the infamous Ryuk, and some of its versions are known to work as wipers, resulting in permanent data corruption.

This particular version came out in mid-July 2022 and did not differ much from its predecessors, although this time, malware appends a randomly-generated extension, which is appended to each of the personal files on the system. Suchlike modified files also lose the original icon – these two are the main symptoms of a ransomware infection.

Other signs include a changed desktop wallpaper, which shows a red triangle on the black background and says “Skynet Cyberdyne Systems.” Unsurprisingly, the malware drops a ransom note on the desktop and other locations and then opens it up automatically. The message inside reads as follows:

———————— ALL YOUR FILES ARE ENCRYPTED ————————

Don't worry, you can return all your files!
All your files documents, photos, databases and other important are encrypted with strongest encryption and unique key.
The only method of recovering files is to purchase decrypt tool and unique key for you.

Discount 50% available if you contact us first 24 hours.

To get this software you need write on our e-mail:
ransom.data@gmail.com

As per usual, crooks attempt to convince victims that paying the ransom is the best way out of this. However, you should keep in mind that ransomware creators are not your friends, and they don't care whether or not you receive your files, even after the asked bitcoins are sent to them. Trusting them is not recommended. Instead, we advise proceeding with Skynet ransomware removal and alternative ways of data recovery.

Malware removal

Most users who get hit by ransomware are first-timers, meaning that they usually know little about the infection and how it works. Ransomware is a rather unique malware, as its component of data encryption does not go away after the virus is eliminated. There are also many peculiarities that many users don't know about, thus, making incorrect moves might result in permanent data corruption.

Therefore, it is vital to perform malware removal in a correct manner. Your first task is to ensure that the virus can not communicate with a remote Command & Control^[2] server, which the attackers commonly use to send commands for execution. In some cases, additional payloads could be sent to your machine, resulting in further compromise.

• Type in Control Panel in Windows search and press Enter
• Go to Network and Internet
• Click Network and Sharing Center
• On the left, pick Change adapter settings
• Right-click on your connection (for example, Ethernet), and select Disable
• Confirm with Yes.

Once you are sure that the system is not connected to the network, you should use sophisticated anti-malware software and perform a full system scan with it. Security software, such as SpyHunterCombo Cleaner or MalwarebytesMalwarebytes, can find and remove all the malicious components from the system at once and any secondary payloads that might be present.

Data recovery and system fix

Despite popular belief, the encrypted data would not be reverted to its previous state after malware is eliminated from the system and its affected network. This is because the deciphering process requires a unique key, which is the possession of ransomware creators.

While restoring files successfully without it is quite unlikely, we recommend trying a third-party recovery tool that might work in some cases or restore at least some of the lost data:

• Download Data Recovery Pro.
• Double-click the installer to launch it.
  
• Follow on-screen instructions to install the software.
• As soon as you press Finish, you can use the app.
• Select Everything or pick individual folders where you want the files to be recovered from.
• Press Next.
• At the bottom, enable Deep scan and pick which Disks you want to be scanned.
• Press Scan and wait till it is complete.
• You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
• Press Recover to retrieve your files.

Some ransomware is simply programmed much worse than others and contains several bugs.^[1] By finding them, cybersecurity researchers can sometimes create a working decryptor that victims can use for free. Keep in mind that this might or might not happen at all, or it might take a while. We recommend checking the following links for the decryptors regularly:

• No More Ransom Project
• Free Ransomware Decryptors by Kaspersky
• Free Ransomware Decryption Tools from Emsisoft
• Avast decryptors

Ransomware is one of the most devastating infections out there, which means that its impact on the operating system can be significant. Not only do these types of malware spread in bulk with other infections, but they might also inject code or damage existing Windows components.

Once malware is eradicated with security software, some of the system files might be damaged or get corrupted. As a result, users might start experiencing system crashes, application errors, slowdowns, and other stability issues. To remediate this, you can employ a PC repair tool that can easily solve all these problems for you automatically.

• Download FortectIntego
• Click on the ReimageRepair.exe
  
  
• If User Account Control (UAC) shows up, select Yes
• Press Install and wait till the program finishes the installation process
• The analysis of your machine will begin immediately
• Once complete, check the results – they will be listed in the Summary
• You can now click on each of the issues and fix them manually
• If you see many problems that you find difficult to fix, we recommend you purchase the license and fix them automatically.

After all these steps are completed, you should ensure to prepare backups of your personal files to avoid devastating ransomware attack consequences. Likewise, reporting the incident to the authorities can help it to tackle cybercrime and increase the probability of cybercriminals' server seizures.
