What is LockOn ransomware virus?

LockOn is another HiddenTear inspired virus

Ransom note by LockOn ransomware virus

LockOn is a ransomware virus that was discovered at the beginning of October 2017. The virus is based on HiddenTear project[1] and uses AES encryption algorithm to lock files on the targeted computer. Following data encryption, crypto-virus shows a program window with a ransom-demanding message.

The virus is written on Lockon Ransomware.exe file. However, it spreads as a [HOT][+18] CHECKER PORN.exe. It seems that people who are interested in adult-themed content might install malicious payload from torrents, file-sharing sites or P2P networks. However, other distribution methods might be used as well.

LockOn ransomware only aims at files that are located in C:\Users\Exploits\Desktop\test directory. When targeted documents, audio, video, image and other data are taken to the hostage, cyber-criminals inform users about the encryption. Judging from the ransom note, the virus aims at English and French[2] computer users.

The ransom-demanding window shows the status of encrypted files and provides instructions how to buy and transfer Bitcoins. Victims are warned that other attempts to remove LockOn or try to restore data will end up with a complete destruction of the device. However, these talks are just a psychologic terror used for threatening people to follow the instructions.

However, doing that is not recommended. Nevertheless, criminals promise to provide decryption key which is supposed to unlock an infected computer; it may not be true. The LockOn virus is based on HiddenTear which is a decryptable ransomware.[3] Therefore, its decryptor might help to restore files as well.

Therefore, after the attack, you should concentrate on LockOn removal and do not believe in threatening hackers’ warnings. For ransomware elimination, you will need to obtain a professional malware removal program, such as FortectIntego. Though, ransomware might modify Registry and affect various system processes in order to boot with system startup and prevent from elimination.

However, you can reboot the device to Safe Mode with Networking as shown in the instructions below and perform automatic elimination without any worries. Please, do not try to locate and remove malicious components from the system manually. It might be dangerous!

However, downloading illegal movies, videos or similar entries is one of the biggest risks to install malware instead. Thus, rule number one – stay away from the illegal content.

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.
