Transformations in cybersecurity

Hackers in the early 2000s began experimenting with many security evasion tactics to beat the existing security tools. They had already come up with techniques to evade security tools on networks. They had also come up with a new attack method called a buffer overflow. A buffer overflow is conducted mostly on client/server apps, where payloads are delivered with data specifically aimed to fill and write outside memory buffers. For instance, hackers would supply scripts to log in input fields in a client app, which would cause the server to import files. Since the server would be expecting just a few characters in the input field, the excess data would cause a buffer overflow, causing it to fail or function erroneously. Exploit toolkits were also being modified to include security evasion tactics.
