A powerful resource covering modern attack scenarios like AI-enhanced phishing, ransomware, zero-days, deepfakes, and more. This playbook provides in-depth insights into emerging cyber threats and mitigation techniques.
You Should Know: Essential Cybersecurity Commands & Practices
1. Detecting Phishing Attempts
Use `grep` to scan suspicious emails:
grep -iE "urgent|password|verify|account" email.txt
Check URLs with `curl` before clicking:
curl -I "https://example.com" | grep -iE "location|server"
2. Ransomware Prevention (Linux)
Monitor file changes in critical directories:
sudo auditctl -w /etc/ -p wa -k etc_changes
Check for unusual processes:
ps aux | grep -iE "crypt|lock|ransom"
3. Zero-Day Exploit Mitigation
Update systems immediately:
sudo apt update && sudo apt upgrade -y Debian/Ubuntu sudo yum update -y RHEL/CentOS
Check kernel logs for anomalies:
dmesg | grep -i "error|warning"
4. Deepfake Detection
Analyze media metadata with `exiftool`:
exiftool suspicious_video.mp4
Verify file integrity via hashing:
sha256sum file_to_check.mp4
5. Network Threat Hunting
Scan for open ports:
nmap -sV target_ip
Monitor live traffic:
sudo tcpdump -i eth0 -n "port 80 or port 443"
What Undercode Say
Cybersecurity is a continuous battle requiring proactive measures. Regular system audits, real-time monitoring, and strict access controls are critical. AI-driven attacks demand AI-powered defenses—automate threat detection with tools like Snort, Suricata, and Wazuh. Always verify sources, enforce MFA, and segment networks to minimize breach impacts.
Expected Output:
- Phishing email flagged via `grep`
- Ransomware process terminated
- Zero-day patch applied
- Deepfake media identified
- Suspicious network traffic logged
