The rapid proliferation of commodity malware is significantly accelerated by open-source information stealers. , a prominent C#-based infostealer freely available on public repositories, serves as a prime case study. This paper examines the anatomy of Stealerium, focusing on its delivery via compressed archives like Stealerium.rar , its aggressive data exfiltration capabilities, built-in evasion techniques, and the defensive posture required by modern security teams. 1. Introduction

Stealerium targets Chromium-based and Gecko-based web browsers. It locates the local SQLite databases holding stored passwords, autofill data, credit card information, and active session cookies. Because session cookies allow attackers to bypass Multi-Factor Authentication (MFA), this is a highly damaging vector. or corporate software updates).
