• Malicious domains registered in proximity to target locations (e.g., Tunisia)
• Anomalies in network traffic indicative of C2 communication
• Presence of custom malware on compromised systems
• High-speed data transfers from sensitive servers

Recommended Actions

• Implement multi-layered email security solutions, including SPF, DKIM, and DMARC.
• Conduct regular vulnerability scans and penetration testing focusing on critical sectors.
• Monitor for unusual network traffic patterns indicative of exfiltration activity.
• Deploy endpoint detection and response (EDR) solutions to track potential APT indicators.
• Partner with threat intelligence feeds to remain updated on Corsair Jackal's TTPs.
