FAQ

===



What?

-----



I'm wondering how many of the "famous" security vulnerabilities have actually been used in attacks that

have been documented, so I made a list.



Couldn't there be unknown attacks?

----------------------------------



Obviously this list can only cover attacks that have been publicly documented, particularly targetted

attacks or attacks within communities with low transparency.



Still if attacks have been widely used it's reasonable to assume that someone will have documented them.



The table is wrong! Attack X has been used!

-------------------------------------------



Please open an issue or a pull request. I created this repo to learn whether my assumptions are correct.



What counts as a real world attack?

-----------------------------------



I realize the distinction can be blurry, but it should be an attack that has been carried out without

the consent of the owner of the affected system and it should've successfully compromised some security

expectation.



Also there should be at least one publicly available description with sufficient detail to make the attack

plausible, not just vague rumors.



There's an important attack missing!

------------------------------------



Open an issue or a pull request, but I may close it if I believe the attack hasn't received sufficient

attention or is a pure marketing stunt.



There's a logo missing!

-----------------------
