Exploits are a quick technique to begin a fileless malware assault since malware may be injected straight into memory without writing anything to the disk. Exploit kits (EKs) are web-based programs hosted by cybercriminals. Exploits are bits of code, command sequences or data collections, and EKs are compilations of exploits. Cybercriminals can use EKs to scale up early compromises. Hackers employ these tools to exploit known vulnerabilities in an operating system or an installed application.
EK operators typically purchase site traffic from botnet operators or malvertising campaigns. Traffic from malicious advertising or compromised websites is sent to an EK’s “gate” where the EK operator chooses only visitors with particular browsers or Adobe Flash versions and redirects targets to a “landing page.”
