SNAKE virus Removal Guide
What is SNAKE ransomware?
SNAKE ransomware – file locking malware that targets organizations and businesses worldwide
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 and encrypting valuable files on servers and networks. First discovered by MalwareHunterTeam 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. 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 firstname.lastname@example.org email address.

Find out about ransomware distribution
Security experts from Virusai.lt 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.
