RDP Bitmap Cache Analysis Aids Cyber Attack Investigations

/ 1 min read

🖼️ RDP Bitmap Cache Analysis Reveals Insights into Cyber Attacks. A recent incident response project highlighted the potential of analyzing Remote Desktop Protocol (RDP) bitmap caches to uncover attacker activities. By examining cached screen fragments, investigators gained a first-person view of the threat actor’s actions, including commands executed and applications accessed. The analysis utilized tools developed by the French and German cybersecurity agencies to reconstruct RDP session images, revealing critical information such as file downloads and browser activity. While the bitmap cache has limitations, such as incomplete data capture and dependency on the initiating machine’s availability, it can significantly enhance investigations by providing context that traditional logs may miss. This approach underscores the importance of correlating various evidence sources in cybersecurity investigations.
