What is Scarab Bin ransomware? And how does it implement its attack?
Another new variant of Scarab ransomware called Scarab Bin ransomware has surfaced. This was spotted in the wild recently and is using .bin extension to mark encrypted files. This new variant follows the same infection sequence as the previous iterations of the ransomware engine. At the time of writing, it isn’t known who the group behind this ransomware is. However, security experts speculated that the crooks might have accessed the original source code of Scarab ransomware.
Once it implement its attack, it may employ a data gathering module used to gather strings that are related to the identity of the user as well as information about the system. The data obtained is used to optimize the attack campaign and is processed by another module called stealth protection used to apply a signature scan that detects any antivirus programs, virtual machine hosts and sandbox environments and prevent them from interfering with the attack. Shortly after these modules are implemented, Scarab Bin will begin encrypting its targeted data that are mostly user-generated such as files with the following extensions:

During the encryption, Scarab Bin uses the same encryption algorithm as the other Scarab variants. It then adds the .[[email protected]].bin suffix to every affected file and releases the following ransom note:
“Your files are now encrypted!
Your personal identifier:
For instructions for decrypting files, please write here:
If you have not received an answer, write to me again!!”
