Deep Dive into Threat Actor Behavior: An EDR-Based Case Study
This report details the analysis of a threat actor's cyber activities, leveraging EDR data to track their behavior. The actor employed automated workflows, utilizing AI tools for data generation and writing, and attempted to exploit tools like Evilginx for man-in-the-middle attacks. Their research targeted various sectors, from banking to real estate, using multiple tools for information gathering and target identification, including Censys and BuiltWith. Furthermore, the actor used residential proxy services to obscure malicious activity and employed Google Translate for message translation. Ultimately, the actor was observed attempting an attack using a project called Voltage_Office356bot, leveraging a script obtained from a well-known security researcher, Dirk-Jan Mollema's blog. This case demonstrates the sophistication of modern threat actors and their proficiency with various tools and techniques, offering valuable insights for security defense.
