APTs utilize methods and technologies differently than other threats. APTs stand for Advanced Persistent Threats, and they are sophisticated and stealthy attacks that target specific organizations or networks over a long period of time, often with political or financial motives. APTs utilize methods and technologies differently than other threats, such as using custom-made malware, exploiting zero-day vulnerabilities, leveraging social engineering techniques, or employing multiple vectors of attack. APTs can also evade detection by existing security tools or controls, by using encryption, obfuscation, proxy servers, or other techniques to hide their activities or communications.
