Найдено: 15 HTTP Basic auth attempts

   Источники: 3 different IP addresses

   Время: Концентрация между 02:00-04:00 UTC

   Credentials: admin/admin, root/password, user/123456

5. Correlation с sessions:
- Найдите соответствующие TCP sessions
- Проверьте successful authentication
- Определите compromised accounts

6. Evidence collection:

public class CustomProtocolParser : Parser

{

    public override bool CanParse(Session session)

    {

        return session.ServerPort == 9999;

    }

    

    public override void Parse(Session session)

    {

        // Extract custom artifacts

        var customArtifact = new CustomArtifact

        {

            SourceIP = session.ClientIP,

            DestinationIP = session.ServerIP,

            Protocol = "Custom",

Workflow анализа PCAP

Структурированный workflow критически важен для consistent и thorough PCAP analysis. В 2026 году forensic teams используют standardized approaches.

Phase 1: Preparation и triage (10-15 минут)

1.1 PCAP validation:

bash

<h2 id="check-pcap-integrity">Check PCAP integrity</h2>

capinfos capture.pcap



<h2 id="basic-statistics">Basic statistics</h2>

tcpdump -r capture.pcap -q | wc -l  # Packet count

tcpdump -r capture.pcap -tttt | head -5  # Time range

1.2 Scope definition:
- Timeframe of capture
- Network segments included
- Expected traffic types
- Analysis objectives

1.3 Resource assessment:
- PCAP size и processing requirements
- Available tools и licenses
- Team expertise level
- Timeline constraints

Phase 2: Initial analysis (30-45 минут)

2.1 NetworkMiner setup:

bash

NetworkMinerCLI.exe -r capture.pcap -o initial_analysis -v

2.2 High-level overview:
- Total hosts discovered
- Protocol distribution
- Time range coverage
- Unusual traffic patterns

2.3 Quick wins identification:

bash

<h2 id="check-for-obvious-issues">Check for obvious issues</h2>

grep -i "password\|credential" initial_analysis/Credentials.csv

grep -E "\.(exe|dll|bat|ps1)$" initial_analysis/Files.csv

Phase 3: Deep artifact extraction (1-2 часа)

3.1 Credential analysis:
- Review all credential types
- Prioritize cleartext credentials
- Correlate с session data
- Check password quality

3.2 File extraction:
- Identify sensitive file types
- Check file sizes for exfiltration
- Verify file integrity
- Extract embedded content

3.3 Session reconstruction:
- Rebuild TCP conversations
- Identify C2 communications
- Analyze protocol usage
- Detect anomalous patterns

Phase 4: Correlation и context (1-2 часа)

4.1 Timeline creation:

bash

<h2 id="combine-all-temporal-data">Combine all temporal data</h2>

python create_timeline.py initial_analysis/ > timeline.txt

sort timeline.txt > sorted_timeline.txt

4.2 Threat intelligence correlation:

bash

<h2 id="check-extracted-iocs">Check extracted IOCs</h2>

python ti_correlation.py extracted_iocs.txt threat_feeds/

4.3 Cross-source validation:
- Compare с SIEM logs
- Correlate с endpoint data
- Validate с network device logs

Phase 5: Reporting и documentation (1-2 часа)

5.1 Evidence organization:

bash

<h2 id="structure-findings">Structure findings</h2>

cp initial_analysis/Files/*.extracted report/files/

5.2 Report generation:

bash

<h2 id="generate-comprehensive-report">Generate comprehensive report</h2>

python generate_report.py initial_analysis/ report/

5.3 Chain of custody:

bash

<h2 id="document-analysis-process">Document analysis process</h2>

echo "Analysis completed on $(date)" >> chain_of_custody.txt

echo "Analyst: $(whoami)" >> chain_of_custody.txt

echo "Tools used: NetworkMiner 2.8, tcpdump 4.99" >> chain_of_custody.txt

md5sum capture.pcap >> chain_of_custody.txt

Phase 6: Quality assurance (30-45 минут)

6.1 Peer review:

FAQ и практические советы

Что такое NetworkMiner и чем он отличается от Wireshark?
NetworkMiner — это network forensics tool, специализирующийся на automated extraction и analysis of artifacts из PCAP files. Он автоматически identifies и extracts files, credentials, certificates, images и другие data. Wireshark — packet analyzer для manual protocol dissection и debugging. NetworkMiner лучше для high-level artifact discovery, Wireshark — для detailed packet inspection.

Как установить NetworkMiner на Linux?
Используйте Mono framework. Скачайте portable ZIP с netresec.com, установите mono-complete, запустите через `mono NetworkMiner.exe`. Для лучшей производительности рассмотрите Wine или виртуальную машину с Windows.

Почему NetworkMiner не показывает некоторые файлы?
Возможные причины: файл fragmented, encrypted traffic (HTTPS), unsupported protocol, или файл не полностью captured. Проверьте PCAP integrity с capinfos, попробуйте tcpdump для verification.

Можно ли анализировать live traffic с NetworkMiner?
Нет, NetworkMiner работает только с PCAP files. Для live capture используйте tcpdump или Wireshark, затем анализируйте PCAP в NetworkMiner.

Как извлечь файлы из HTTPS трафика?
NetworkMiner не декодирует SSL/TLS. Для HTTPS analysis: 1) Получите SSLKEYLOGFILE от browser/server, 2) Используйте Wireshark с decryption keys, 3) Export decrypted traffic как PCAP, 4) Analyze в NetworkMiner.

Поддерживает ли NetworkMiner Wi-Fi captures?
Да, но требует radiotap headers в PCAP. Захватывайте с Wireshark или tcpdump с `-I` flag для monitor mode. NetworkMiner извлекает data link layer information.

Как оптимизировать анализ больших PCAP файлов?
1. Pre-filter с tcpdump: `tcpdump -r large.pcap -w filtered.pcap 'port 80 or port 443'`
2. Increase memory buffer в NetworkMiner settings
3. Use CLI version для batch processing
4. Split large PCAPs на chunks
5. Use SSD storage

Безопасно ли использовать NetworkMiner?
Да, если следовать best practices: run в isolated environment, не открывать suspicious files, keep updated, use antivirus scanning. NetworkMiner не executes code, только analyzes packets.

Как интегрировать NetworkMiner с SIEM?
Export results в CSV/JSON format, use API или log shipping. Для Splunk: configure input для NetworkMiner CSV files. Для ELK: use Filebeat для ingestion.

Почему некоторые credentials показаны как hashed?
NetworkMiner extracts как есть. NTLM hashes выглядят как base64 strings, Kerberos tickets — binary. Для cracking используйте Hashcat или John the Ripper.

Можно ли анализировать traffic от mobile устройств?
Да, если capture содержит mobile protocols. NetworkMiner распознает iOS backup traffic, Android ADB, mobile app communications. Для decryption mobile traffic нужны специальные инструменты.

Как обновить NetworkMiner?
Portable version: скачайте новый ZIP, replace files. Installed version: используйте built-in updater или uninstall/install. Проверяйте compatibility с вашей Windows/.NET version.

Что делать если NetworkMiner crashes на больших PCAPs?
Increase virtual memory, close other applications, use CLI version, split PCAP на smaller files, check для corrupted packets, ensure sufficient disk space.

Поддерживает ли NetworkMiner IPv6?
Да, полностью. IPv6 traffic анализируется аналогично IPv4, с proper address resolution и protocol detection.

Как извлечь custom artifacts?
Develop custom parsers с .NET/C#. Implement Parser interface, override CanParse() и Parse() methods. Register parser в NetworkMiner configuration.

Безопасно ли отправлять PCAP файлы в поддержку?
Нет, PCAPs содержат sensitive data. Sanitize перед отправкой: remove sensitive IPs, anonymize data, focus на specific issue. Или опишите проблему без sharing PCAP.

Как использовать NetworkMiner в enterprise среде?
Deploy portable version на analyst workstations, use CLI для automated processing, integrate с case management systems, implement approval workflows для sensitive captures.

Что такое "anomaly detection" в NetworkMiner?
AI-powered feature (NetworkMiner 2.8+) для identification unusual traffic patterns, potential security incidents, или suspicious behavior based на machine learning models.

Поддерживает ли NetworkMiner 5G traffic analysis?
Да, распознает 5G core protocols, но требует specific capture methods. 5G traffic encrypted, так что analysis limited без decryption keys.

Как экспортировать данные для отчетов?
Use built-in export: CSV для credentials/files, HTML reports, XML для structured data. Customize exports через Tools → Export options.
