The .aes256 Ransomware – More Information

This type of ransomware virus is from the file encryption kind, meaning that it alters the structure of the files within the victim’s PC.

How Did I Get Infected by .aes256 Virus

In order to infected victims, there may be many methods used by this virus. It may use a distribution malware, like Trojan.Downloaders or even botnet type of malware, to cause infections, it really depends on the resources, the cyber-criminals behind it have.

Another way of infecting victims is via performing multiple different attacks via social media and other platforms that have online chat. The cyber-crooks may send out web links that download and execute by force the malicious executable of the .aes256 virus.

The most common method, responsible for over 80% of ransomware infections is the e-mail spam. What cyber-criminals do is they use so-called kits that include pre-generated convincing e-mail messages as well as disposable e-mail accounts and the required software to spam these messages with malicious attachments from those accounts. This may result in fake e-mails, pretending to be from services such as FedEx, Amazon or other organizations that ask the user to open the attachment, for example deceiving him or her that a purchase has been made and the invoice (which is the attachment) has to be opened.

After the attachment is open, infection may take place and multiple malicious files may be downloaded onto the victim’s computer. These files are usually located in critical Windows folders, such as the following:

  • %Roaming%
  • %AppData%
  • %Local%
  • %LocalRow%
  • %SystemDrive%

The files may usually have randomly generated names or names that resemble legitimate Windows programs (like “notepad.exe”, to fool that their activity is original when they are running as a process in Windows Task Manager.

After Infection By .aes256 Ransomware

  • Videos.
  • Photos.

  • Files belonging to often used programs.

After the encryption takes place, the files assume the .aes256 file extension after their original one. They may look like the image below displays:

The ransomware virus, known as the AES virus also displays it’s ransom note named “!!!Read This_Important!!!.txt” to make sure the victim knows of it’s presence. The ransom note also mention that the RSA-2048 cipher has been used to encrypt the decryption key. The message in it is the following:

“<<<<<<<<<<<<<<<<<<<< YOUR FILES ARE ENCRYPTED! >>>>>>>>>>>>>>>>>>>>
SORRY! All personal files on your computer are encrypted.
File contents are encrypted with random key (AES-256; ECB mode).
Random key is encrypted with RSA public key (2048 bit).
We STRONGLY RECOMMEND you NOT to use any “decryption tools”.
These tools can damage your data, making recover IMPOSSIBLE.
If you want to decrypt your files, you have to get RSA private key.
In order to get private key, write here:
[email protected]
[email protected]
Also you can write to BitMsg (https://bitmsg.me) address
if you did not receive any answer on e-mail:
You will receive instructions of what to do next.
You MUST refer this ID in your message:
{VICTIM ID here}
<<<<<<<<<<<<<<<<<<<< YOUR FILES ARE ENCRYPTED! >>>>>>>>>>>>>>>>>>>>”
