SNAKE ransomware is a dangerous infection that can delete files’ Shadow Volume Copies

SNAKE ransomware is data locking malware that has been infecting various enterprises^[1] and encrypting valuable files on servers and networks. First discovered by MalwareHunterTeam^[2] in January 2020, operations of malware seized for several months, until May, when researchers noticed a large spike of infections globally. Among the victims – Europe’s largest private hospital Fresenius.^[3] Threat actors also claim that they managed to copy valuable files and will most likely use it as another extortion point.

The malware is written in Golang and includes a complex activity module comparing with other infections of this kind. The malware disables tasks that are related to SCADA systems, remote software, virtual devices, etc. Afterward, SNAKE ransomware executes the encryption process by using the AES-256 and RSA-2048 algorithms and adding a random 5 symbol appendix to each filename. Additionally, every encrypted component acquires an EKANS file marker (which is “SNAKE” backward). Then, ransomware places the Fix-Your-Files.txt ransom message in the C:\Users\Public\Desktop directory and offers to purchase the decryption software by contacting the cybercriminals via [email protected] email address.

SNAKE ransomware is capable of deleting the Shadow Volume Copies^[4] of encrypted files by executing specific PowerShell commands. This way the developers seak to harden the recovery process of all locked files and documents. Another thing that the malware might do is permanently damage the Windows hosts file in order to prevent users from visiting security sources. So, once you are completing SNAKE ransomware removal, do not forget to eliminate the hosts file.

SNAKE ransomware does not include any particular ransom price via the text message it provides. However, the criminals are likely to urge for a cryptocurrency transfer such as Bitcoin in order to remain safe and untrackable. Take a look at how the entire Fix-Your-Files.txt ransom message looks like:

| How can you be certain we have the decryption tool?

—————

In your mail to us attach up to 3 files (up to 3MB, no databases or spreadsheets).

We will send them back to you decrypted.

SNAKE ransomware might also be capable of avoiding antimalware detection of some particular software. For this purpose, the malware might run specific tasks in the Task Manager location or insert particular keys in the Windows Registry section. However, according to VirusTotal information,^[5] the malicious update.exe file has been detected by 46 AV tools from the total 69. Some of the detection names include Gen:Win32.AV-Killer.ItW@aei5Gqj, Trojan.Win32.Antavmu.asdd, Trojan-Ransom.b, Ransom:Win32/Killpror!MSR, etc.

SNAKE ransomware stores both encryption and decryption tools on remote servers and keeps then unreachable for other people except the cybercriminals themselves. This malicious string aims to lock all types of files and documents that are found on the infected Windows computer system except folders such as windir, SystemDrive, :\$Recycle.Bin, :\ProgramData, :\Users\All Users, :\Program Files, :\Local Settings, :\Boot, :\System Volume Information, :\Recovery, \AppData\.

Continuously, SNAKE virus can bring numerous losses to big companies and businesses as it is known to be targetting various networks and their computers worldwide. However, this is not the only ransomware virus who gets involved in such types of activities. Other malware forms such as Ryuk ransomware, BitPaymer ransomware, Sodinokibi ransomware, Maze ransomware have also been infecting big companies and demanding inadequate ransom payments.

In addition, SNAKE ransomware might deliver other infectious strains to the Windows computer system such as Trojan viruses, worms, spyware, cryptocurrency miners, etc. These types of parasites might relate in the theft of personal information, credentials and money from your bank account, the installation of other malicious software, program and service corruption, system freezes and crashes, severe computer and file damage, CPU overusing.

You should remove SNAKE ransomware from the infected Windows computer to avoid these types of risks and be able to recover encrypted data. Download reliable automatic software and complete the entire process with it. Also, use a tool such as Reimage Reimage Cleaner Intego that might help you fix some malware-corrupted system settings/files. Afterward, go to the end of this article and try some data recovery steps that are definitely better than paying the demanded ransom price and risking to get scammed. 

Find out about ransomware distribution

Security experts from Virusai.lt^[6] claim that ransomware is spread by using stealth and deceptive techniques. The hackers often look for multiple sources available so that they could distribute their malware to a wider range of users. However, the most popular ransomware distribution places include:

• Email spam. Malware often is distributed through phishing email messages and their infectious attachments. The criminals often pretend to be a reliable shipping organization such as FedEx or DHL and deliver a notification including order confirmation in the attached file that is truly the malicious payload.
• Software cracks. The criminals often plant the malicious payload into cracked software that is placed on peer-to-peer networks such as The Pirate Bay, BitTorrent, and eMule.
• Unsecured RDP. If the RDP includes weak protection or has none at all, the hackers can easily manipulate the settings and remotely connect to the targeted Windows computer system.

What you have to do is always be careful while viewing your email messages. Do not enter any suspicious hyperlinks added and do not download any attachments without scanning them with antimalware software. Continuously, download all of your products and services only from reliable sources and their original developers.

In addition, you should always secure your RDP configuration with strong and reliable passwords that contain letters, numbers, and some symbols. Last but not least, ensure that you have trustworthy and strong antivirus protection running on your Windows computer. This tool will inform you if something malicious is trying to escape.
