This lab focuses on the detailed analysis of a malicious campaign involving a file associated with the Stealc malware family. The scenario begins with a suspicious email containing a seemingly urgent attachment, which later triggers a security alert due to a potentially malicious download. By examining the provided artifacts and leveraging tools like VirusTotal and Any.Run, the investigation uncovers the behavior, tactics, and techniques employed by the malware.
Through the analysis, we delve into various aspects of the malware, including its family identification, creation time, communication with a command-and-control (C2) server, initial post-infection activities, configuration settings, and evasion techniques. Key insights are revealed, such as its use of the RC4 encryption key, its focus on credential theft from browser password stores, and its self-deletion behavior to avoid detection. Each discovery aligns with specific MITRE ATT&CK techniques, providing a clear picture of the adversary's methods and operational flow.
This lab provides an excellent opportunity to enhance understanding of real-world malware analysis, from identifying its behavior to mitigating its impact. By dissecting the malware’s actions step by step, participants will gain valuable skills in leveraging threat intelligence, analyzing malware configurations, and applying defensive strategies to combat similar threats effectively.
