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

Aurora ransomware is a file-encrypting threat that was first discovered on May 30, 2018. Apparently, it’s back again as security experts spotted it out in the wild. This new variant still uses the .Aurora suffix in marking its encrypted files. Basically, nothing much has changed in this new variant.

Once it starts to carry out its attack, a malicious payload is dropped in the system which activates the crypto-virus. From there, it establishes a connection to a remote Command and Control server controlled by the attackers. It may also employ an information gathering module in order to obtain information about the infected PC and its user. The harvested data is then sent to the remote server where the ransomware downloads the additional malicious file that helps it in the execution of its attack. These malicious files are placed in the system folder which helps the crypto-malware from being detected by any antivirus programs or security software. Some of the malicious files also modify the Windows Registry which allows the crypto-malware to run on every system boot. After all these changes are applied, Aurora ransomware will start its search for targeted files to encrypt. Once it finds them, it applies the same encryption algorithm in locking the files. Following data encryption, it appends the .Aurora extension to each one of the encrypted file. It also releases a ransom note named “!-GET_MY_FILES-!.txt” that states:

“==========================# YOUR PC BLOCK #==========================

SORRY! Your files are encrypted.

File contents are encrypted with a random key.

We STRONGLY RECOMMEND you NOT to use any “decryption tools”.

These tools can damage your data, making recover IMPOSSIBLE.

Also, we recommend you not to contact data recovery companies.

They will just contact us, buy the key and sell it to you at a higher price.

If you want to decrypt your files, you have to get RSA private key.

In order to get private key, right here:

oktropys@protonmail.com

And send me your id, your id:

-[redacted 9 numbers] And pay 50$ on 1DVrBzv6hb1D217NNqbjaForF3eG3HXc7a wallet

If someone else offers you files restoring, ask him for test decryption.

Only we can successfully decrypt your files; knowing this can protect you from fraud.

You will receive instructions of what to do next.

==========================# YOUR PC BLOCK #==========================”

The cyber crooks behind Aurora ransomware demand $50 worth of ransom in exchange for the “RSA private key”. However, contacting these crooks and paying the ransom demanded is certainly not recommended as they can’t be trusted and you could end up losing money for nothing. The best thing you could do is to use alternative methods to recover your files but first, you have to wipe out Aurora ransomware from your computer.

How does Aurora ransomware proliferate?

Just like its predecessor, this new Aurora variant proliferates via malicious spam email campaigns where an obfuscated file is attached. This file may be a ZIP file, PDF file or a document with macro scripts used to launch Aurora ransomware in the computer. This is why you have to be careful in opening any emails no matter who the sender is as it could contain the malicious payload of Aurora ransomware.
