What is Seon ransomware?

Seon ransomware – data locking malware that is using GreenFlash Sundown exploit kit for propagation

Seon ransomwareSeon ransomware is a computer virus which locks up important data and urges a ransom.

Seon ransomware is a typical crypto malware that uses the AES encryption algorithm to lock data and then demands a ransom to be paid for the decryptor. It was first spotted in November 2018 and appended .FIXT file extension to documents, pictures, videos, databases, and others, although it skips system files. Seon virus dropped YOUR_FILES_ARE_ENCRYPTED.txt ransom note that disclosed contact emails of crooks: and While the initial infection used phishing emails[1] and similar methods for distribution, hackers came up with the Seon ransomware 0.1 and 0.2 on January 1st, 2019, and started circulating the malicious payload with the help of GreenFlash Sundown exploit kit. The newest variants do not differ much from their predecessor, although victims are also presented with a readme.hta along with the text ransom note. Additionally, criminals provided as three new contact email addresses for the communication.

Seon ransomware was first distributed with the following ransom note:

As evident, cybercriminals are asking for Bitcoin or other cryptocurrencies[2] in exchange for the decryption tool. The usage of digital wallets is preferable by hackers, as it helps them to remain anonymous while illegally asking money from their victims. Seon ransomware authors should not be trusted, as, even after transferring the payment, they might simply ignore the victim and keep the money.

With the 0.1 and 0.2 versions, seems like criminals decided to develop the Seon ransomware even further, as it now started to be propagated with the help of GreenFlash Sundown EK, and included a more professionally-looking readme.hta ransom note. Additionally, while file extension remained the same, crooks provided five contact emails that, in addition to previous two emails, included,, and

If you carry out each step carefully, you will have a chance of recovering encrypted files such as photos, videos, audios, databases, text documents, and others.

Beware of spam emails and patch your system with security updates

Keeping your system up to date might save you from ransomware infections. Exploit kits are designed to abuse flaws in the code of software, which makes outdated machines vulnerable. All those users have to do is visit a malicious website or get redirected, and, in a matter of seconds, the infection spreads throughout the system. Thus, do not postpone any updates and immediately patch your apps and system.

Seon ransomware virusSeon ransomware - a cryptolocker which infiltrates the PC via spam messages and their rogue attachments

According to technology experts from[3], ransomware viruses are distributed via phishing emails – attachments or malicious links. Hackers employ bots that send out thousands of phishing emails to thousands of users. While spoofed emails can be easily recognized by most, there will always be those who will fall for the trick and open contaminated attachment or click on a malicious link. Therefore, experts advise being extremely careful when handling emails from unknown sources, especially if the attached document is asking to enable macro function.

Furthermore, rogue websites can also distribute ransomware. For example, P2P networks[4] sometimes might include virus-related components injected into links or somewhere else. This happens because such pages do not fit the security requirements and often lack protection. If you have accidentally overcome a questionable-looking website, make sure that you close it the same second and do not think of returning.

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
