The image of Nulltica GUI

Nulltica virus happens to be just another file-encrypting threat based on the infamous HiddenTear ransomware.[1] As common for this type of ransomware, it attaches .lock file extension and launches its GUI called as “Information.”

The ransom note instructs you to create a bitcoin wallet, pay 50 USD, and copy the code of the wallet in the indicated decryption box. Interestingly, after the supposed payment, the files will not revert to its original form but acquire another extension – .unlock.

However, there is no certainty that after this procedure, the data will be fully decoded. Therefore, this crypto-virus has hints to the malware released last year – Polski ransomware.[2]. The source code also refers that the malware aims to steal Facebook login data. While, there is no specific information about this malware detected on the social network, it would be better to stay vigilant.

The malware also tends to disguise under important.exe, though it is possible that it might disguise under alternative name. If you noticed its files, it would be better to reboot the system and remove Nulltica as soon as possible. FortectIntego or Malwarebytes might be of assistance in this situation.

Facebook targeted again?

It seems that along with a new academic year, the season for spam season in Facebook has begun as well. Recently, it has suffered a several consecutive series of Facebook Message[3] and video virus assaults. Unfortunately, users still fall for the same trick by clicking on a video message containing their profile picture.

The ability to acquire Facebook login data makes sense as hijacked accounts are expected to be the main catalyst factor in conducting a malspam campaign. Therefore, it is another reason to perform Nulltica removal as soon as possible. The picture illustrating Nulltica virusAt the moment, Nulltica ransomware demands $50 in ransom

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.
