[Case Study: Latrodectus] Analyzing and Implementing String Decryption Algorithms

This article has a slightly different objective than the last ones I published, it is not about an analysis of specific malware. Today’s article is about a case study of the Latrodectus string decryption algorithm (analyzed in the previous research). The objective is to study how to identify a string decryption algorithm when reverse engineering

Latrodectus [IceNova] – Technical Analysis of the… New IcedID… Its Continuation… Or its Replacement?

My first public malware research was for a strain of IcedID. A few months later, in my nighttime activities, I was working on technical analysis research for Sodinokibi (REvil), a Ransomware that is no longer seen, however, is part of the evolutionary history of the business model that we now know as RaaS. But, I

IcedID – Technical Analysis of an IcedID Lightweight x64 DLL

My first public malware research was regarding an x32 PE stager (exe) from the IcedID family. In this research I analyzed three samples from different years, with the aim of identifying code reuse, and developing a Yara signature capable of detecting any IcedID sample, based on fixed code patterns persistent over the years. So you
