emerged in late 2022 as an educational tool on GitHub , but was quickly adopted and weaponized by threat actors. When packaged as Stealerium.rar , the malware relies on social engineering and compressed archive delivery chains to bypass perimeter defenses and land on victim machines. 2. Delivery Mechanism: The Role of Stealerium.rar
