Another interesting project from OWASP -> OWASP Wrong Secrets! It's a game that provides examples of how NOT to store secrets in software. Definitely worth playing Github Repo: github.com/OWASP/wrongsec… Demo: wrongsecrets.herokuapp.com
Zobaczcie jakie to proste: - zakłada się profil anglojęzyczny o mocnym tytule (World of Statistics) - publikują tylko światowe statystyki - niektóre są prawdziwe, większość zmanipulowana - podajemy to dalej bo to duży profil z niebieskim badgem - tak się sieje ruską dezinformację
