Sage ransomware. Another virus with a well-designed ransom payment page
Sage virus is another professional ransomware that can compete with viruses like Cerber. Just like any other illegal program, Sage malware sneaks into the computer system after making the victim believe that it is a legitimate file. As soon as it gets into the system, it executes itself and encrypts files stored on the system with a RSA-4096 cipher. During this process, the virus also decorates each corrupted file with a .sage file extension. Following a successful encryption, Sage ransomware replaces current computer background with [6 random chars].bmp, which holds information about the cyber attack and says that the victim must open !Recovery_[6 random chars].txt or !Recovery_[6 random chars].html file and learn how to get the encrypted files back. These files contain commands that tell the victim to go to a particular website. First of all, the victim needs to confirm that one is not a robot and enter a combination of symbols shown in a picture. Then, one shall proceed to an individual ransom-payment website, which has five different pages – Home, Payment, Test decryption, Instructions, and Support.

The payment website contains a lot of text regarding the encryption procedure. The virus seeks to convince the victim that there is no way to decrypt files except paying the ransom. Samples of Sage that we have encountered asked for 0.2 – 0.7 Bitcoins, which means that cyber criminals are testing different ransom prices to see how willingly victims pay it. Sadly, ransomware is a powerful virus, and unless the developer is a complete fool, there is no way to restore files without a private key that is created during the encryption process – it is also known as the decryption key, which can be used for data recovery. However, we usually do not advise paying the ransom because cyber criminals rarely show any interest to interact with victims after infecting their computers. They just seek to collect payments; therefore, if you have been infected with such malware, better start Sage removal process instead of buying Bitcoins for cyber criminals and willing to get Sage_Decryptor.exe. To remove Sage virus, we highly recommend using anti-malware program like Reimage Reimage Cleaner Intego or SpyHunter 5Combo Cleaner.
Update. At the beginning of 2017, the second version of this virus emerged. Sage 2.0 virus reportedly spreads via .ZIP archives that contain another .ZIP archive inside. The final .ZIP archive has either a malicious Word or JS file, which, once executed, downloads and installs Sage 2.0 ransomware on the system. The updated variant of Sage has excluded the “Test Decryption” page from the ransom payment page, and this time it demands for a much larger ransom – about 2 Bitcoins. The virus also adds .sage file extensions to target files that it encrypts and drops !Recovery_[3 random chars].html ransom note on desktop. More information about Sage v2.0 malware can be found here.
How could I allow ransomware to infect my computer?
Unfortunately, ransomware authors are very sneaky. They craft professional-looking email messages and send them out to thousands of recipients. Such emails usually contain one malicious file attachment that executes the ransomware virus on the system. Additionally, scammers might send out letters with malicious URLs or images that contain URLs to websites that host exploit kits. Exploit kits can be used for ransomware distribution. Finally, it is possible (and very likely) to download malware alongside pirated software. If you want to stay away from shady content online, better not click on anything that raises at least a bit of suspicion to you. Of course, it is highly recommended to install trustworthy anti-malware program for your safety.
