Concretly, how often do security breaches happen due to timing attack? I can't grasp how severe this things are.

- otabdeveloper4 5y agoProbably 0.00001% of the cases. The other 99.9999% is when somebody forgot to change a password after an employee left.
- extrapickles 5y agoThe current record[0] in exploiting a timing difference is on the order of 100ns over the Internet. You can do much better if you can get your attack to execute on the same CPU as the victim (eg: the cheaper cloud servers you typically share the cpu with others). I don’t think it’s a popular way in as there are easier and less noisy vulnerabilities to exploit (misconfigurations, protocol errors, etc).
