Scarab-Bin Virus – In-Depth Analysis

The Scarab-Bin virus follows the same set infection sequence as previous iterations of the ransomware engine. At the moment there is no information about the hacker or group behind it, however it is speculated that they have accessed the original Scarab source code from one of the hacker underground markets and have used it to create their own versions. The other possible explanation behind the new virus’s creation is a buy order to malware developers requesting a customized Scarab instance in return for a payment.

Depending on the included set of modules and the attack campaign the actual infection may begin with a data harvesting command. It instructs the virus engine to start gathering strings that are related to the user’s identity. The other type of harvested information is related to various data that can be used to optimize the attack campaigns. A sample list of the targeted information includes the following:

This data can then be processed by the stealth protection module which can be made part of the Scarab-Bin virus engine. Such components apply a signature scan that detects installations of anti-virus software, virtual machine hosts or sandbox environments. Their real-time engines will be disabled as part of the infection process.

Following the ransomware’s installation it can also launch various system modification commands that will make it possile to modify the target systems in various ways. One of the major modifications are done to the Windows Registry wherein entries belonging both to the operating system and any user-installed entries can be made.

Scarab-Bin Virus — Encryption

The ransomware engine is started after all other components have finished running. In a similar way to previous versions it uses a built-in list to determine the target files that are to be encrypted with a strong cipher. An example list can include the following data types:

  • Archives
  • Backups
  • Images
  • Music
  • Videos
  • Documents

The victim files are renamed with the .bin extension which includes a string in brackets containing the hacker’s contact email address. The collected samples in the ongoing attack are labeled with the .[[email protected]].bin extension. They are accompanied by the following ransom note:
