In cybersecurity, 'Anti' refers to techniques or features used by malicious software (malware) to evade detection, analysis, or removal by security tools and researchers. Commonly, these methods include anti-debugging, anti-virtualization, and anti-forensics, which are designed to prevent analysts from studying the malware's behavior or code. By employing 'Anti' measures, cybercriminals make it harder for defenders to understand, detect, and mitigate threats, increasing the malware's effectiveness and longevity.
