.aes Files Virus – Update February 2019

February 2019 brings a new ransom note and variant to the .aes Files Virus. Researchers dubbed it the Australian AES ransomware. The ransom note’s message is wrapped up in a GUI interface with red color, which can be previewed from the below image:

The full text from the note reads:

– Why have my files been encrypted? –
You files have been encrypted. This includes many of your important documents and other types of files, database, system files and more. Upon inspecting these encrypted files you may discover that they are using an unbreakable encryption algorithm, which can only be unlocked and decrypted with a special key.
This key can only be obtained though a bitcoin payment listed below. This is a certain way to recover and safely decrypt all your important files to get them back. All files after the amount is paid in full will be decrypted. This offer only has a certain time limit though and it’s your choice whether you want the key permanently destroyed, so your files can not be decrypted at all.
For some background info, this is a simple, fund raiser attempt in the desperate, dark void of the internet. It’s a noble thought intended to be good, as it’s also been thought for years, but it’s job is by doing right by those bad. All funds collected are filtered, then giving to charities that matter, so that as a collective of victims, a bigger reward is given to those who need it. If a small amount, is multiplied by thousands, those small interuptions in those people’s lives, come at a greater cost for those who benifit from it more.
– How to pay for encrypted files? –
Bitcoin is a popular cryptocurrency nowdays, and therefore it’s easy to buy bitcoin. For Australian’s, bitcoin.com.au has a $50 BTC minimum limit.
Therefore, the amount is set at $60 AUD. Go to the bitcoin.com.au website and go through the steps to purchase the bitcoin. Next, use the bitcoin address provided below to send the bitcoins to that address. After that, simply wait for the time to expire and if the bitcoin’s have been paid, the decryption key will be released.

Send $60 worth of bitcoin to this BTC address: [Copy Address] 37XsqpzsJRu9pdi5KQmdZgAYPn3qhxbdDZ
Time left: 47:59:23
Decryption Key: *** [Copy Key] Enter Key: [ ] I have paid the BTC amount to the correct address above.
[Purchase Bitcoin] [Decrypt] —–

However, malware researchers have found a secret in the ransomware’s code. Pressing the combination of the Alt + M keys will display a set of other messages, in a small window box and provide the victim with a free decryption.

This is the content of the messages:

If you found this by accident, nice luck. The decryption key is released before the timer, you can now decrypt your files.
Your files are now being decrypted. DO NOT close the application or your files will be corrupted and unrecoverable. The program will alert upon completion of deletion.

Just wait and all files should get restored back to normal.

The decryption key was never going to be deleted, your files are now able to be unencrypted. To do so click the ‘I have purchased the BTC checkbox’ and using the decryption key, enter it into the textbox, and click decrypt. Watch as your files magically unencrypt. Thanks for the donation.

Times Up!!

The last message displayed above is actually hidden inside the code of the ransomware.
