What are runtime Atacks?

• atacks launched during program runtime
• affects programm after it is loaded | not program's binary
  • -> hard to detect
• vulnerability: flaw in system, that enables atacker to utilize system in manner other than intended
• exploit: taking advantage of a vulnerability to cause unintended behavior of a system
• 0-day exploits: unknown exploit not publicly disclosed

Some Atacks

• denial of service: make service unavailable
• remote code execution: ability to trigger arbitrary remote code execution
  • atacker executes his code in order to gain control of the victim machine
• privilege escalation: optain certain priviliges
• shell: user interface for access to services on a system

buffer-overflow-vulnerability

• atacker can execute arbitrary code by injecting it at memory address where program runs out of bounds
