What is Erenahen ransomware? And how does it carry out its attack?

Erenahen ransomware is a new ransomware threat that targets important files in a computer. It is designed to encrypt them using a sophisticated encryption algorithm and demand ransom from users in exchange for the recovery of the encrypted files. It adds a “.erenahen” extension to every file it encrypts. At the time of writing, there is only a handful of information about this threat but according to security experts, it may be a variant of GlobeImposter 2.0 ransomware.

As soon as its malicious payload is dropped on a targeted machine, Erenahen ransomware will start to carry out its attack. It connects the computer to a remote Command and Control server where it downloads other files that will be used for its attack. These files are placed on system folders. It then begins employing an information-gathering module to obtain data in the system. The obtained information will be used for the other module called stealth protection which is used to keep the crypto-malware undetected. Erenahen ransomware also makes modifications in the Windows Registry to achieve persistence in its attack. After the system modification, it begins encrypting files and following the encryption, it adds the .erenahen extension to each one of them and then opens a file named “How_to_open_files.html” which has the following content:

“Your files are encrypted!
What happened?
Your files are encrypted, and currently unavailable.
You can check it: all files on you computer has new expansion.
By the way, everything is possible to recover (restore), but you need to buy a unique decryptor.

Even though this ransomware is capable of encrypting files it doesn’t mean that you will pay the demanded ransom. Paying the ransom is too risky as there is no way of knowing whether the crooks behind this ransomware will really give the decryption key. Instead of worrying much you can simply get rid of Erenahen ransomware. And besides, there are other ways to recover files without having to pay the ransom demanded by the crooks.

How does Erenahen ransomware proliferate?

The same with the previous variants, the malicious payload of Erenahen ransomware is disseminated through malicious spam email campaign. The authors of Erenahen ransomware often attached seemingly safe files just like with the previous variant, the crooks added an attachment which they disguise as photos – and it may the same thing with the new variant although they might be using other file types such as documents or ZIP files so you have to be careful in downloading any email attachment no matter how harmless it may look.
