How Vigilant Researchers Can Uncover APT Attacks

In this presentation at the DEF CON 29 Recon Village, senior security consultant and malware analyst Ladislav Baco explores how independent researchers can proactively hunt and uncover Advanced Persistent Threat (APT) campaigns without enterprise-scale resources. He begins at 05:00 by advocating for a proactive hunting mindset that prioritizes behavioral anomaly tracking over reliance on static, signature-based intrusion detection systems.

Ladislav examines host-level behavioral indicators at 10:00, illustrating how nation-state actors frequently deploy Living-off-the-Land Binaries (LOLBins) such as PowerShell and WMI to blend in with normal administrative traffic. He explores techniques for detecting low-and-slow lateral movement and off-hours credential misuse at 15:00, explaining how adversaries establish footholds while avoiding endpoint detection thresholds.

At 20:00, Ladislav details network telemetry analysis, explaining how to identify subtle periodic beaconing patterns and anomalous data exfiltration channels communicating with external servers. He concludes at 25:00 by demonstrating how to correlate disparate technical artifacts using the Diamond Model and map adversary techniques against the MITRE ATT&CK framework to publish actionable threat intelligence.
