Hi @SecurityTube how do you feel about ppl posting walk through of attackdefense lab? There are solutions on the site but I ended up doing a lot of research I'd like to share.


I ended up not having the time to do #metsploitctf this past weekend. I only got root on the ubuntu server via the libssh vuln. Still enjoyed it. Thanks @rapid7 great job on the set up


Started #metasploitctf tonight! Found the apache struts on the ubuntu box. No flags yet... already falling behind let's see how far I get this weekend


Me: Was going to cancel @lifelock News: #Marriottbreach Me: never mind
