CYBERSECURITY ATTACKS PLAYBOOKS: Modern Threats & Defense Strategies

Listen to this Post

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
