Tenhle týden se vůbec na podobných twitterových účtech urodila Spousta Dobrých Rad™️. V odpovědích na tohle vlákno xitter.cf/sijsu/status/164015773… jedna organizace obhajuje (mj. stylem "ale správci hesel mají taky zranitelnosti") jakýsi systém karet, že se prý tak dá vytvořit silné heslo

The idea behind my latest XSS challenge was to bypass a strict CSP to execute arbitrary XSS without using parentheses. I explained the solution in detail, with mini-research alongside, in this article medium.com/@terjanq/arbitrar…. Check it out!😃 #javascript #xss #bugbountytips
