[BabbleLoader] A Deep Dive into EDR and Machine Learning-Based Endpoint Protection Evasion

Every now and then, some group innovates the Malware market, and it seems that the BabbleLoader developers are willing to do this, but not by discovering new evasion techniques, but rather by knowing how to use them to evade detection products that contain Machine Learning (AI). This research will cover the following topics: Below is […]

[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
