Ambrosia Virus

Ambrosia virus is the name given to a data locker ransomware based on the code of the Scarab ransomware. The ransomware aims to trick people into starting malicious files on their operating systems so that it can corrupt essential system settings and encrypt personal files. The virus is designed to evade detection and reach valuable personal files stored on available drives. Target files get encoded with a sophisticated encryption algorithm. That’s why all encrypted files remain inaccessible. They could be recognized by the malicious extension .ambrosia as the ransomware appends it to their names. The original filenames will be changed to a string of random characters. For example, the image file trip.jpg will be renamed to 3g000000000p0Zw9VkBVGnK5dMRu2hI8.ambrosia. At last, the Ambrosia ransomware drops its ransom note file that is called HOW TO RECOVER ENCRYPTED FILES.TXT. The content of this text file aims to blackmail victims into paying a ransom for a decryption tool possessed by hackers.

Distribution and Impact of Ambrosia Ransomware

Security researchers reported that Ambrosia virus is a strain of the vicious ransomware family Scarab. For the distribution of Ambrosia ransomware virus may be used a few traditional propagation techniques – torrent files, malspam, fake software installers, hacked websites, URLs on social media posts, etc. The most popular is malspam. This technique is preferred by hackers as it enables them to distribute their malicious code on a large scale. Massive email spam campaigns are trying to deliver ransomware to target machines. They usually present file attachments that contain the malicious code or URLs that land on hacked websites.

Commonly used types of files such as documents, PDFs, images are likely to be misused for the spread of Ambrosia ransomware payload. As for the attachments, are often presented as:

  • Invoices coming from reputable sites, like PayPal, eBay, etc.
  • Documents from that appear to be sent from your bank.
  • An online order confirmation note.
  • Receipt for a purchase.
  • Others.

When the Ambrosia ransomware payload starts on your computer it triggers a long sequence of malicious activities. To complete the attack, Ambrosia virus needs to establish additional malicious files. It could drop and create these files in some of the following folders:

  • %AppData%
  • %Local%
  • %LocalLow%
  • %Roaming%
  • %Temp%

By executing malicious files, the ransomware misuses system processes and remains invisible. After the contamination of certain system settings, Ambrosia virus reaches the data encryption stage.

For the completion of this stage, the ransomware activates a built-in cipher module that scans predefined folders for target files. Then this module encrypts all target files by utilizing a sophisticated cipher algorithm. Like its predecessors, Ambrosia Scarab ransomware is likely to use the AES cipher algorithm to encrypt data. As a result, you may have all your valuable files inaccessible. Files encrypted by Ambrosia ransomware will be completely renamed. They will appear with strange names of random characters and the extension .ambrosia at the end.

You may not be able to use your:

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
  • Banking credentials, etc

At the end of the attack, Ambrosia virus drops the ransom message HOW TO RECOVER ENCRYPTED FILES.TXT

Here is what you can read when you open the message:

All your files have been encrypted

Your ID:

All your files have been encrypted
If you want to restore them, write us to the e-mail: ambrosiaa@protonmail.com or ambrosiaa@bigmir.net

You have to pay for decryption in Bitcoins. The price depends on how fast you write to us.
After payment we will send you the decryption tool that will decrypt all your files.

FREE DECRYPTION AS GUARANTEE
Before paying you can send to us up to 1 files for free decryption.
Please note that files must NOT contain valuable information
and their total size must be less than 1Mb

Attention!
Do not rename encrypted files
Do not try to decrypt your data using third party software, it may cause permanent data loss
If you not write on e-mail in 2 days – your key has been deleted and you cant decrypt your files

This message attempts to trick you into transferring a ransom fee to hackers. Although they promise to send an efficient decryption tool for .ambrosia files, we recommend that you avoid paying them the ransom. There is no guarantee that their tool will be able to decrypt encoded files.
