How to remove Aurora Ransomware and decrypt .Aurora files

What is Aurora ransomware

Aurora, or OneKeyLocker, is a new ransomware virus that may encode all the personal files on a victim’s computer. Business/work documents, personal photos and videos – all of it may be encrypted, so that no one can use these files until they pay ransom cost, which is usually a big sum of money. If your PC is infected with this dangerous virus, we should warn you that paying ransom cost would not help. Cyber criminals are not going to help or contact you even if you pay them. Still, you may remove Aurora ransomware and decrypt .Aurora files without paying anything.

Interesting fact – this ransomware may infect a PC through malicious websites. These sites belong to a intermediary-host ardis.ru, which itself hosts at hostland.ru, which controls a bunch of malicious and dangerous websites. Who runs this whole thing with Ardis.ru? The address in Kaliningrad, but there is a Swedish personal name in it, and the company representative is from the Netherlands. It is super strange, but the answerphone of technical support says that they work from 9am, but if you call later, they do not work at all. So, there is still no idea where these people operating from and why they do what they do.

The way this ransomware works is quite simple – first of all, Aurora breaks through your system, then starts encrypting procedure with DES encryption algorithm. Aurora ransomware adds .Aurora extension to the name of all the encrypted files, here’s an example: may18_raport.doc.Aurora. Once all the data is encrypted, the ransomware drops 6 same text files:

HOW_TO_DECRYPT_YOUR_FILES3.txt
HOW_TO_DECRYPT_YOUR_FILES4.txt
