**Blackhat tactics** refer to the malicious and unauthorized methods used by hackers to exploit vulnerabilities in computer systems and networks for personal gain or to cause harm. These tactics include activities like unauthorized access, data theft, and system manipulation, often involving the use of malware and other cyber attacks to disrupt systems or steal sensitive information. Blackhat hackers employ these tactics clandestinely, using advanced knowledge of programming languages, network protocols, and software flaws to evade detection and achieve their malicious objectives[1][3][5].
