Great write up by @sans_isc on how you can use #ossec to contain a compromised host on your network. They leverage the active response #feature to quarantine an infected host and get it out of rotation while you investigate. #serversecurity isc.sans.edu/forums/diary/S…

And it looks like it is fixed already. If you are wondering what happened, they pushed an old DNSSEC key live by mistake. In portuguese: eng.registro.br/pipermail/caiu… Thanks @spookerlabs for the link ^

Multiple Brazilian sites (eg uol.com.br, amazon.com.br) are down due to what looks like a DNSSEC issue on .com.br: dnsviz.net/d/www.uol.com.… dnsblacklist.org/?domain=www.uo… If you can't reach your favorite Brazilian sites, that's probably why.

The centralization of the web is showing its face. When Google, Facebook and Twitter control what you can and can not say online - censorship & political bias will happen. It started by removing security videos, now even videos from doctors that had expressed their opinions.

Extremely frustrated at what tech giants like @YouTube and @Facebook are doing these days with the removal of information from their platforms with no choice. @sundarpichai @SusanWojcicki @finkd even more shocked at how quiet other technologists appear to be about this. 😞
