Summary

In this podcast, Prabh Nair interviews Shrutirupa Banerjiee, a senior malware researcher, about ransomware investigation. The discussion begins with Banerjiee’s career journey and the importance of practical skills. The core of the video is a detailed explanation of the ransomware attack chain, focusing on the role of batch loaders (batloaders) as an initial delivery mechanism. Banerjiee demonstrates a live investigation of a Malox ransomware attack, showing how an obfuscated batch file decodes base64 payloads and executes PowerShell scripts to deliver the final ransomware. She emphasizes the importance of understanding the entire infection chain, from initial delivery to final execution, and highlights common patterns such as obfuscation, gzip decompression, and base64 decoding. The video provides practical insights into malware analysis techniques, including deobfuscation and process monitoring, and concludes with lessons learned for defenders.
