Cyber threats continue to evolve, making it essential to understand the various attack vectors used by malicious actors. Below is an in-depth analysis of common cyber attacks, along with practical commands and steps to defend against them.
You Should Know:
1. Phishing Attacks
Phishing remains the top cyber threat, where attackers impersonate legitimate entities to steal sensitive data.
Detection & Prevention:
- Use email filtering tools like SpamAssassin:
sudo apt-get install spamassassin sudo systemctl enable spamassassin
- Verify suspicious links with URL scanners:
curl -I "https://example.com"
2. AI-Powered Attacks (Deepfake & AI Phishing)
AI-driven attacks use machine learning to create convincing fake content.
Mitigation:
- Detect deepfake videos using Forensic Tools:
git clone https://github.com/ondyari/FaceForensics
- Monitor network traffic for anomalies:
tcpdump -i eth0 -w traffic.pcap
3. Supply Chain Attacks
Attackers compromise third-party vendors to infiltrate target organizations.
Defense:
- Scan dependencies for vulnerabilities:
npm audit pip-audit
4. API Attacks
Exploiting insecure APIs to steal data or disrupt services.
Protection:
- Test API security with OWASP ZAP:
docker run -v $(pwd):/zap/wrk -t owasp/zap2docker zap-api-scan.py -t https://api.example.com -f openapi
5. Fileless Malware
Malware that runs in memory, evading traditional detection.
Detection:
- Monitor process memory with Volatility:
volatility -f memory.dump pslist
6. Evil Twin Attacks (Fake Wi-Fi Networks)
Attackers create rogue Wi-Fi hotspots to intercept data.
Prevention:
- Verify Wi-Fi networks using Airodump-ng:
sudo airodump-ng wlan0
7. DNS Tunneling
Exfiltrating data via DNS queries.
Detection:
- Analyze DNS logs for anomalies:
cat /var/log/dnsqueries.log | grep "unusual.domain"
8. Zero-Day Exploits
Attacks targeting undisclosed vulnerabilities.
Mitigation:
- Apply patches immediately:
sudo apt update && sudo apt upgrade -y
