What is Oled ransomware virus?

Oled ransomware encrypts your files to have a reason for demanding a ransom

Oled ransomware

Oled virus is a ransomware program that cripples personal files stored on the system and marks each of them with [black.mirror@qq.com].oled extensions. Following a successful data encryption, the virus drops a text file called DECRYPTION.txt on the desktop. This file is a ransom note[1] that contains information on how to restore files encrypted by the ransomware.

It holds victim’s ID number, criminals’ email address – black.mirror@qq.com, and a link to LocalBitcoins for those willing to pay a ransom. The criminals suggest that the sooner the victim writes to them, the lower the ransom price will be. The attackers also suggest providing proof for those who do not believe that data decryption is within criminals’ discretion – the victim is invited to send up to 3 files for free decryption; however, their total size must not exceed 5 Mb.

The more recent version of the threat also revealed the relation with additional threats and new features that indicate the Oled ransomware virus attack. readme-warning.txt is the ransom note file that is the same for other versions of the same family, like KJHslgjkjdfg ransomware. New releases also include oled@airmail.cc as a primary email for the developers. It is possible that 2020 may present more advanced attacks of this ransomware family. Recent detection[2] rates show that anti-malware tools can possibly help with such infections, there is no reason to consider paying the ransom.

Currently, victims whose computers were compromised by this ransomware can only restore files using data backups since there are no third-party tools capable of decrypting .oled files. We also advise removing the virus as soon as possible because it is an extremely dangerous computer program that poses a threat to the computer and your privacy. Having it on the system increases the risk of attracting even more malware to the system. For Oled ransomware removal, we suggest using proper anti-malware software.

Do not rename or move encrypted files – this may compromise the integrity of the decryption process
Do not try to decrypt your data using third party software, it may cause permanent data loss.

Oled ransomware can damage your files permanently, and it might no longer be possible to open them ever again. It uses a sophisticated encryption method that allows changing files on a structural level. Such modification can be reversed only with the help of a decryption key, which is also known as a private key[3].

The private key is required to restore corrupted files; however, criminals keep it on their servers and suggest victims buy it for a particular price in order to recover files. Sadly, ransomware crooks are not the people that can be trusted, so we highly recommend you remove Oled virus without any doubts and not pay the ransom.

You have already lost your files – do not take the risk of losing your data as well. If you have a data backup of simply copies of your files on an external data storage device such as USB, hard drive or in online data storage services such as DropBox, kill the Oled ransomware virus and then import intact file copies to the computer system. Fix virus damage using FortectIntego, for example. Oled virusOled virus encrypts files and appends [black.mirror@qq.com].oled file extension to each of them. To restore corrupted data, the virus suggests paying a ransom to its developers.

Distribution of ransomware includes shady infiltration and malicious files

Ransomware viruses are typically installed on the victim’s computer using various fraudulent means. In most cases, criminals add malicious files to emails they send to thousands of victims with subject lines related to well-known companies and services. Nowadays, ransomware no longer travels in the form of .exe files, and in fact, the majority of email services do not allow sending such file format anymore. Now they either inject the virus into Word or Excel files or spread it in the form of a JavaScript file.

Launching such files makes the malicious script connect to a particular web page and download the ransomware from there. If you want to prevent ransomware from encrypting your files, consider installing a good anti-malware software and bypassing suspicious emails that fall into your Inbox folder.

It is also advisable to never visit Internet pages that seem to be untrustworthy or deceptive. If you follow these easy rules, you shouldn’t lose your files due to a ransomware attack. For extra protection, create yourself a data backup, so you can recover from ransomware attacks quickly.

Remove Oled ransomware fully from the system without leaving anything behind

Ransomware is a fearsome computer infection that should be removed from the system as soon as possible. To remove Oled ransomware virus, restart your PC and run it in Safe Mode with Networking. Once you do so, install a good anti-malware software and run a complete system scan with it. Security tools like SpyHunter 5Combo Cleaner or Malwarebytes an help you clean the system.

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.
