The FortiGuard Labs Incident Response (FGIR) team recently investigated a long-term cyber intrusion targeting critical national infrastructure in the Middle East, attributed to a state-sponsored threat group. The attack involved extensive espionage operations and suspected network prepositioning—a tactic often used to maintain persistent access for future strategic advantage.
Key Findings:
- Novel malware deployed throughout the intrusion
- Detailed breakdown of adversary TTPs across different attack stages
- Indicators of Compromise (IOCs) for defenders
- Attribution insights

You Should Know: Detecting & Mitigating Similar Attacks
1. Identifying Network Prepositioning
State-sponsored attackers often use:
- Living-off-the-land binaries (LOLBins) – Legitimate system tools abused for malicious purposes.
- Persistence mechanisms – Scheduled tasks, registry modifications, or hidden services.
Commands to Check for Persistence:
Check scheduled tasks (Windows) schtasks /query /fo LIST /v Check registry autoruns (Windows) reg query HKLM\Software\Microsoft\Windows\CurrentVersion\Run Linux cron jobs for hidden tasks crontab -l ls -la /etc/cron.
- Detecting Malware with YARA & Log Analysis
Use YARA rules to scan for malware signatures:
yara -r /path/to/malware_rules.yar /var/log/
Analyzing Suspicious Logs:
Check for unusual SSH access grep "Failed password" /var/log/auth.log Monitor network connections netstat -tulnp ss -tulnp
3. Hunting for IOCs
Extract hashes, IPs, and domains from the report and scan your systems:
Search for known malicious hashes
find / -type f -exec md5sum {} + | grep "MALICIOUS_HASH"
Check active connections against threat intel feeds
sudo tcpdump -i eth0 -w capture.pcap
4. Hardening Critical Systems
- Disable unnecessary services:
systemctl disable unnecessary_service
- Enforce strict firewall rules:
ufw deny from SUSPICIOUS_IP
- Enable logging & monitoring:
auditctl -a always,exit -F arch=b64 -S execve
What Undercode Say
State-sponsored cyber intrusions are becoming more sophisticated, leveraging legitimate tools to evade detection. Defenders must:
– Monitor for unusual process execution (ps aux | grep -i "suspicious_process")
– Analyze network traffic (tcpdump -i eth0 'port 80 or port 443')
– Implement strict access controls (chmod 700 sensitive_files)
– Use threat intelligence feeds (abuse.ch, AlienVault OTX)
Key Commands for Incident Response:
Memory dump analysis volatility -f memory_dump.raw pslist Check for rootkits rkhunter --check Extract suspicious files from disk foremost -t all -i disk_image.img
Expected Output:
- Detection of persistence mechanisms
- Identification of IOCs in network logs
- Enhanced monitoring for LOLBin abuse
- Improved defensive measures against APTs
Prediction
State-sponsored attacks on critical infrastructure will increase, with adversaries using AI-driven evasion techniques. Organizations must adopt zero-trust architectures and automated threat hunting to stay ahead.
