Deploy and query Arkime (formerly Moloch) for full packet capture network
|
|
traffic analysis. Uses the Arkime API v3 to search sessions, download PCAPs,
|
|
analyze connection patterns, detect beaconing behavior, and identify suspicious
|
|
network flows. Monitors DNS queries, HTTP traffic, and TLS certificate anomalies
|
|
across captured traffic.

# Implementing Network Traffic Analysis with Arkime
|
|
|
|
## Instructions
|
|
|
|
1. Install dependencies: `pip install requests`
|
|
2. Configure Arkime viewer URL and credentials.
|
|
3. Run the agent to query Arkime sessions and analyze traffic:
|
|
- Search sessions by IP, port, protocol, or expression
|
|
- Download PCAP data for forensic analysis
|
|
- Detect C2 beaconing via connection interval analysis
|
|
- Identify DNS tunneling through query length statistics
|
|
- Flag connections to known-bad TLS certificate issuers
|
|
|
|
```bash
|
|
python scripts/agent.py --arkime-url https://arkime.local:8005 --user admin --password secret --output arkime_report.json
|
|
```
|
|
|
|
## Examples
|
|
|
|
### Beaconing Detection
|
|
```
|
|
Source: 10.1.2.50 -> 185.220.101.34:443
|
|
Sessions: 288 over 24 hours
|
|
Avg interval: 300s, Jitter: 4.2%
|
|
Verdict: HIGH confidence C2 beaconing (jitter < 5%)
|
|
```
