What is Mogera ransomware?

Mogera ransomware – a complex malware form that might be capable of several malicious activities

Mogera ransomware virusMogera ransomware is a version of the Djvu and STOP families

Mogera ransomware is a sibling of Djvu and STOP viruses which includes a complex structure. The main working principle of this ransomware is to stealthily infiltrate the targeted system, drop the malicious payload and start performing the encryption process after which files end up with the .mogera appendix attached. Later on, Mogera virus launches a ransom note named _readme.txt which presents all important information about receiving the decryption tool for locked files. Crooks state that contact needs to be made in a three day time period and the ransom price will drop from $980 to $490. All the victim needs to do is text these hackers by emails bufalo@firemail.cc, gorentos@bitmessage.cc, or by telegram @datarestore.

Mogera ransomware will drop its malicious payload in the form of an executable file which is located in the %AppData% or %LocalAppData% folder. Once this happens, the malware can launch its malicious code and start using unique algorithms such as AES or RSA[1] for data encrypting purposes.

These cyber threats are known for their ability to collect various sensitive information about the user and his/her used machine. Later on, these types of details might be misused for illegitimate actions, for example, identity theft.[2]

If some particular data about the computer's system is gathered, Mogera ransomware virus might also misuse this information for security bypassing purposes. Some malware uses fake but legitimate-looking computer security certificates so that they could easily install on the system and plant their malicious components in it.

Mogera ransomware can leave all types of damaging content in locations such as the Windows Task Manager or even modify the Windows Registry to create and inject its own malware-based registry keys. These entries might cause various system changes also they might let the ransomware to activate itself after every machine reboot.

What is more, Mogera ransomware might also end up planting other forms of malware on the infected computer system. Usually, these types of threats let in malicious programs such as spyware, trojans, cryptocurrency miners, and similar. These infections might also relate to slow computing work, severe software damage, data theft, and so on.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
