PCAP investigation summary
What happened
Windows host 10.20.30.227 (DESKTOP-4C02EMG, Kerberos principal alejandrina.hogue) downloaded a PE executable over cleartext HTTP from http://gengrasjeepram.com/sv.exe (server 49.51.133.162).
The same host sent repeated HTTP POST requests to twereptale.com (81.177.6.156) at /4/forum.php and /mlu/forum.php with unusual user-agent strings, a pattern suitable for beaconing review.
No packet evidence establishes execution of the downloaded PE or any successful exfiltration; endpoint payloads were not decrypted and no actor attribution is supported.
Who was involved
- 10.20.30.227 is the internal host that downloaded the PE and generated the suspicious POST traffic.
- Kerberos client principal alejandrina.hogue is bound to host 10.20.30.227.
What remains uncertain
- Whether the downloaded PE executed or established persistence is unestablished; encrypted payloads were not decrypted and no endpoint execution was observed.
- Reputation of the download and POST destinations is inconclusive: VirusTotal was rate-limited and ThreatFox/MalwareBazaar returned not_found or not-applicable, which does not mean clean.
Next check
- Submit the recovered PE (SHA-256 995cbbb422634d497d65e12454cd5832cf1b4422189d9ec06efa88ed56891cda) for sandbox detonation and reputation lookup to determine maliciousness.
Analyst-review draft. Exact evidence references and provider provenance are retained in the structured record.
