From the Wireshark capture:

A (iraniansk.com): This domain is not a known legitimate resource and is hosting a suspicious file named “Fy.exe,” strongly indicative of a malware distribution domain.

D (Fy.exe): The Content-Disposition: attachment; filename="Fy.exe" header explicitly signals a binary executable download, a key indicator in Emotet campaigns.

While Content-Type: application/octet-stream (E) is typical of binary data transfers, it is not unique to malware and cannot by itself serve as a strong IoC. The nginx server (B) and cookie/hash string (C) similarly do not uniquely indicate compromise.
