: Generate MD5/SHA256 hashes of the zip and its contents.

To provide a useful write-up, I wouldg., malware analysis, digital forensics, or cryptography). If you can provide the or list the contents of the zip file, I can walk you through the analysis steps. Common Analysis Framework for Such Files

Execute files in a sandbox (like Any.run or Hybrid Analysis) to observe network callbacks or registry changes.

If this is a security-related zip, here is the standard procedure a write-up would follow:

: Use file or ExifTool to confirm if it is a standard ZIP or a disguised polyglot file. Static Analysis

: Run strings on the contents to look for hardcoded passwords, URLs, or API calls.

: Check for NTFS Alternate Data Streams (ADS) if the file originated from a Windows environment. Dynamic Analysis (If applicable)

: If it contains scripts (PowerShell, VBS, JS), look for base64 strings or XOR-encoded payloads. Forensic Investigation
