What is Estemani ransomware?

Estemani ransomware – a file-locking threat that adds no extension to encrypted data

Estemani ransomwareEstemani ransomware - a ransom-demanding malware that urges 0.75 BTC for the decryption software

Estemani ransomware is a ransom-demanding malware that emerged at the second have of August and appears to encrypt data by adding no appendix to the file names. However, criminals focus on English-speaking users and aim to launch an English-based ransom message that comes in a text document named HOW_DECRYPT_FILES.txt. The spreaders of Estemani virus announce that various files have been locked with the mixture of RSA 2048 and Salsa20[1] algorithms and the only way to reverse them back to their previous states is by purchasing the decryption software straightly from the hackers for a price of 0.75 BTC. Additionally, the email address is provided as the way to contact the crooks.

Removal Use FortectIntego to discover all malware-laden objects on your computer system. Continuously, use only automatical software to remove the ransomware virus

Estemani ransomware might carry a more complex module than we might think. For example, some ransom-demanding threats are capable of erasing Shadow Volume Copies and making the decryption process harder to carry out so that the victims will end up buying the crooks' offered decryption software instead.

In addition, some malware such as Estemani ransomware can carry other malware attached to themselves. This way you can end up with a notorious Trojan horse or cryptocurrency miner on your computer system. Avoid such dangerous possibility by terminating the ransomware virus immediately.

Besides, do not fall for believing in the claims that are provided by Estemani ransomware as you cannot be guaranteed that by paying the demanded ransom price you will truly receive the decryption tool. Here is how the message looks like:

We are pleased to announce successful encryption of your machine.
All the hosts in your network have been encrypted with FUD and powerful encryption algorithm(s) – RSA-2048 + Salsa20.
Any attempt to decrypt data by yourself is futile.

The cost for decryption begins from 0.75 Bitcoins (BTC) and depends on your business size.
Email address:

Note: The Host ID and Email addresses are unique and private. Any leak of information will result in direct ban to our services.
We won’t be responding to any communications about free decryption. We follow simple business policy – No Money! No Decryption.

Estemani ransomware removal can be carried out with the help of automatical software. However, first, you have to reboot in Safe Mode with Networking to ensure that no malicious processes are running on your computer system. Continuously, perform a full machine scan with FortectIntego to locate all malware-laden objects.

Estemani ransomware is not the type of program to play with as the longer you keep it on your computer, the bigger the damage might be. Besides, keep in mind that you might find malicious processes left by this malware in the Windows Task Manager and Windows Registry[2] sections in the form of entries, keys, files, tasks, etc.

After you remove Estemani ransomware, you can take a look at the data recovery software that we have provided at the end of this article. Furthermore, note that precautionary measures for avoiding similar incidents in the future are necessary to take. Keep on reading and figure out what kind of steps you can take to move towards full machine safety.

Email spam – the most liked place by ransomware spreaders

Experts from[3] claim that email spam campaigns are the ones that spread ransomware viruses and other malware forms very often. Due to this fact, it is very important to manage all of your received emails. This means, identifying the sender, checking the message for possible grammar mistakes, scanning all attached files with antivirus software.

In addition, the malicious payload can be delivered through unsecured domains of gambling, online-dating, gaming, and porn-watching websites. Here you need to be careful of questionable-looking hyperlinks and adverts. However, the best thing to do would be not to visit such directories ever at all.

Continuously, installing reliable security software into your computer system is also a necessary step to take. Choose a reputable tool and ensure that you update it regularly, otherwise, the program might start failing.

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.
