: Calculate the CRC32 or BLAKE2sp hashes to identify individual files within the archive.
Running the sample in a sandbox like ANY.RUN or Hybrid Analysis would reveal its actions:
: Verify the file is a valid Roshal ARchive (RAR) .
Based on general patterns in malware analysis and archive-based threats, here is a write-up structure to investigate this file: 1. Static Analysis (Initial Findings)
The first step is to analyze the file without executing it to understand its structure and intent.
: Investigate if the archive attempts to exploit CVE-2023-38831 , a high-profile WinRAR vulnerability where opening a file in a specially crafted archive can execute a hidden malicious script. 2. Behavioral Analysis (Dynamic Sandbox)
