What is Scarab crab ransomware? And how does it implement its attack?
Scarab crab ransomware is the latest addition to the Scarab ransomware family. This new Scarab variant seems to imitate GandCrab ransomware as it uses the .crab extension in marking its encrypted files. However, aside from the identical extension, it does not have other similarities with GandCrab ransomware. 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.
When it comes to its attack, Scarab crab ransomware still uses the same pattern as other Scarab ransomware variants. Once its malicious payload is dropped in the system, it starts to implement its attack by using a data gathering module used to obtain information about the system and its user. The harvested data is then used for another module called stealth protection which is 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 crab ransomware will begin encrypting its targeted data that are mostly user-generated such as files with the following extensions:

Following data encryption, Scarab crab ransomware opens a file named “HOW TO RECOVER ENCRYPTED FILES.txt” which contains the following message:
“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!”
