Cyber threats are evolving rapidly, and staying informed is critical for defense. Below are the top 8 cyber attacks expected in 2025, along with detection and mitigation techniques.

1. Phishing Attacks

Attackers impersonate trusted entities to steal credentials.

Detection:

grep -r "urgent action required" /var/mail

Mitigation:

sudo apt install spamassassin 
sudo systemctl enable spamassassin

2. Ransomware

Malware encrypts files, demanding payment for decryption.

Prevention:

sudo chmod -R 700 /sensitive_data

Recovery:

restic restore --target /recovery latest

3. DNS Spoofing

Redirects traffic to malicious sites.

Detection:

dig +trace example.com

Mitigation:

sudo apt install dnscrypt-proxy

4. Zero-Day Exploits

Unknown vulnerabilities exploited before patches.

Detection (Linux):

sudo apt-get update && sudo apt-get upgrade --dry-run

5. Man-in-the-Middle (MITM) Attacks

Intercepts communication.

Prevention:

sudo arpon -i eth0 -d

6. SQL Injection

Exploits database vulnerabilities.

Detection:

sudo grep -r "SELECT.FROM.WHERE" /var/www

7. DDoS Attacks

Overwhelms servers with traffic.

Mitigation:

sudo iptables -A INPUT -p tcp --dport 80 -m limit --limit 25/minute --limit-burst 100 -j ACCEPT

8. IoT-Based Attacks

Compromises smart devices.

Prevention:

sudo nmap -sV --script vuln 192.168.1.0/24

You Should Know:

  • Network Monitoring:
    sudo tcpdump -i eth0 -w capture.pcap
  • Log Analysis:
    journalctl -u ssh --no-pager | grep "Failed password"
  • Windows Command (Detecting Suspicious Processes):
    tasklist /v | findstr "unknown"

What Undercode Say:

Cyber threats in 2025 will leverage AI and automation, making defenses like behavioral analysis and zero-trust models essential.

Prediction: AI-driven phishing will bypass traditional filters, requiring adaptive ML-based defenses.

Expected Output:

Phishing attempts logged: 12 
Ransomware attempts blocked: 5 
DDoS mitigated: 3
