What is .2xx9 file extension virus?

.2xx9 file extension virus attack can corrupt your files without possibility to recover them

.2xx9 file extension virus is just another name of Dev-Nightmare ransomware virus. This ransomware project is based on Hidden Tear ransomware source code, and it is yet another tool used to carry out cyber criminal activity. This malicious virus wants money, so it encrypts victim’s files stored on the computer and also on all plugged-in devices. After encrypting the file, it appends .2xx9 file extension to it, making it clear which files are encrypted and which ones are not. Sadly, most likely you will not find many healthy files on the system after Dev-Nightmare .2xx9 ransomware attack. When the virus finishes corrupting the data, it starts another command – creates a ransom note and saves it on the desktop. The ransom note is hidden behind a basic text filename – READ_ME.TXT, and contains the following message:

Your Sysytem is inficated with Dev-Nightmare 2xx9 Ransomware
You All Files and database are encrypted.
If you want your files back contact me at devnighmare2xx9@gmail.com

Send me some money or bitcoins

And I hate fake peoples.

We assume that hacker wants to say that he or she is not ready to read heart-grabbing email messages from victims asking for the decryption key for free. Unfortunately, the criminal is not going to treat victims with compassion, so there is no need to waste time trying to convince him/her to give away the decryption key for free. Files can be recovered either from backups or using HiddenTear decryptor, which might help to decrypt locked data. However, victims of this nasty ransomware should remove .2xx9 file extension virus before taking any actions to restore data. .2xx9 file extension ransomware removal can be completed using a powerful anti-malware tool, for example, FortectIntego or SpyHunter 5Combo Cleaner.

How does one get infected with ransomware?

Ransomware is a severe virus, and it is programmed to deceive the computer user and convince him or her to install it unknowingly. For that, ransomware threats behave like Trojan horses. They can arrive at victim’s email box in the form of mail attachment that looks like a safe file, for instance, Word document or PDF file. Once launched, it downloads malware from the Internet and executes it. Another way to be infected with .2xx9 file extension malware is to download software updates from untrustworthy third-party sites carelessly. Remember that bogus software updates often travel together with malicious files bundled to them. Therefore, to keep your computer virus-free, install software updates ONLY from legitimate websites. Your computer might be infected with ransomware by using exploit kits, so please keep all your software up-to-date to prevent hackers from exploiting security vulnerabilities.

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.
