LOLBins, short for 'Living Off the Land Binaries,' are legitimate system tools and programs - especially those built into Windows - that cybercriminals misuse to carry out malicious actions. Instead of using obvious malware, attackers exploit these trusted applications to avoid detection by security software. Common examples include PowerShell, CertUtil, and WMIC. By leveraging LOLBins, attackers can download files, execute commands, or move laterally within a network, all while blending in with normal system activity and evading security monitoring.
