Utilizing collaborative security to collect data on attacks we were able to detect Log4J in a quite unusual but effective manner. We'll show you how CrowdSec enables the entire infosec community to stand together by detecting attempts to exploit a critical 0day, reporting them centrally thereby enabling anyone to protect themselves shortly after the vulnerability was made public. The unusual part is that this is done using FOSS software and by analyzing logs of real production systems but in a way that doesn't compromise the anonymity of anyone (except the attacker, of course) and doing so with a reliable result where poisoning and false positives are almost impossible. Too good to be true? Come by and judge for yourself!
