Is Lock93 ransomware related to Locky?

Lock93 virus belongs to the group of recently discovered file-encrypting malware. It is associated with the same hackers who released suppteam01@yandex.ru threat.

File-encrypting viruses are no novelty to any Internet users. Cerber and Locky keep sweeping their way throughout the world, so few are not aware of what ransomware does. In recent years, the activity of such viruses has boosted significantly. Speaking of Lock93, it does not stand out much. While using a trojan, it sneaks into the system and locks all the data. You might notice strange Windows messages warning you of suspicious programs running in your background. While executing its commands, the threat locks all the data and adds .lock93 extension file. Though .Locky and .locked extensions are popular among many ransomware creators; it is suspected that the virus might be generated by the same hackers who disguise under new versions of CrytoLocker.

.Lock93 file extension virus displays bilingual text for English and Russian speakers. It is called as ИНСТРУКЦИЯ INSTRUCTION.txt file. The threat demands 1000 rubles in exchange for the files. The victims should contact the hackers using oplaticydadeng@mail.ru to recover the files. There is additional mail provided: zaplatiddeng@yandex. ru. As usual, it threatens the victims not to meddle with the files as any action might irreversibly damage them. Certainly, it is a common habit among ransomware creators. You should proceed to the elimination process of Lock93 malware.

How does the virus spread?

It has been detected that the threat spreads in two ways. It targets users via spam messages. To convince victims to open the message, the cyber criminals make up fake police notifications or tax reports. After a user clicks on the supposed attachment containing invoice or another official report, he or she activates the threat. In some cases of Lock93 ransomware, its executable lies in the explorer.exe file. By using Trojan-Ransom.Win32.Crypmodadv.xda, the ransomware infiltrates the system. If you do not own a proper security application or the software is outdated, then there are more than enough chances for Lock93 hijack to occur.

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
