What is Cyclone ransomware?

Cyclone ransomware is written using Python programming language

Cyclone ransomware illustration

Cyclone virus is a malicious program which is designed to prevent people from accessing their files by encrypting them. This crypto-malware is written in Python programming language, and it encodes data using the AES-256 cipher[1]. Afterward, it appends .cyclone suffix at the end of the filename and opens Cyclone Ransomware v2.40 window asking for ransom.

The pop-up window can be called as a ransom note since it provides information about the data encryption and how to decrypt the corrupted files. Victims of Cyclone are demanded to pay 0.005 Bitcoin to the specific account in order to regain access to their documents.

The fraction of Cyclone ransom note:

Your documents, videos, images and other forms of data are now inaccessible, and can not be unlocked without the decryption key. To acquire this key, transfer the Bitcoin Fee to the specified wallet address before the time runs out. If you fail to take action within this time window, the decryption key will be erased and access to your files will be permanently lost.

The authors of Cyclone indicate a specific time period during which the victim has to make the transaction, or the corrupted files will be permanently deleted. This is a standard way to gain illegal profits by intimidating people. However, paying the ransom might not solve the problem rather than make it even worse.

Note that cybercriminals are malevolent people seeking for money. Likewise, you might be tricked to pay the ransom and left without a decryption key. We advise you not even to consider obeying the rules of the crooks since there are alternative methods how you can regain access to your data. Thus, do not hesitate and remove Cyclone right away.

Experts from[2] say that employing FortectIntego or any other reliable antivirus tool is the best way to complete Cyclone removal safely. This security application is designed to eliminate ransomware without damaging the compromised data. Therefore, you will be able to try to recover it using the instructions below.

Hackers use multiple techniques to distribute ransomware

Typically, the criminals spread obfuscate files in the cyberspace which trick users into opening them and infiltrating malware. They might either be attached to the spam emails or distributed as fake software installers/updates.

Therefore, you should never download suspicious and unauthorized files from peer-to-peer (P2P) networks or deceptive pop-up ads[3]. Note that if you click on the malicious attachment or file, it will connect to the domain hosting the ransomware and download it to your computer.

Therefore, we recommend you to use a reputable security software to scan the files before downloading them. Additionally, keep it updated since it will increase malware detection rate and protect your system from new high-risk computer infections.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
