|
| Data Window | [Start] to [End] |
|
|
| Status | [ ] In Progress / [ ] Complete |

## Hypothesis
|
|
> Compromised endpoints are beaconing to adversary C2 infrastructure using periodic HTTP/HTTPS/DNS connections with detectable frequency patterns.
|
|
|
|
## Data Sources
|
|
- [ ] Proxy logs
|
|
- [ ] Firewall logs
|
|
- [ ] Zeek conn.log
|
|
- [ ] Zeek dns.log
|
|
- [ ] Zeek ssl.log
|
|
- [ ] Sysmon Event ID 3 (Network Connection)

## Recommendations
|
|
1. **Block**: [Domains/IPs to block at firewall and proxy]
|
|
2. **Isolate**: [Endpoints to contain via EDR]
|
|
3. **Detect**: [New detection rules to deploy]
|
|
4. **Hunt**: [Additional IOCs to sweep for across the environment]
