Reverse Engineering in practice. Configuring Cisco, IPTables and other firewalls with a sweet graphical utility. A little nostalgia with the Hak5 BBS and cracking open the Pineapple, a demo of Jasager.
[ MP4 | XviD | WMV ]

Production Note

With this episode and onwards we fixed the issue that was mudding up the sad standard-def video signals from our cameras. We’re still working on going HD and hope to be there by the end of the year. More details.

Show Notes

Chris Gerling shows us how to do a little reverse engineering with an educational tool called a CrackMe. These aptly named CrackMe files are great for practicing reverse engineering skills. Chris walks us through the steps involved in unlocking the Crackme’s code using .NET Reflector, some Python code, and a little a hex calculator. More detail in Chris’ blog post and more Crackmes at LearnSecurityOnline.com.

Matt demonstrates a killer app for anyone who manages firewalls. Firewall Builder creates, validates and deploys configurations to popular firewalls from your standard Linksys WRT54G using Sveasoft, to iptables, to Cisco using an intuitive graphical interface. Can we say access-list inside_access_out permit tcp any eq www host hak5.org eq www? Check out Matt’s full review at MattLestock.com

Remember the good ol’ days before the Internet? Ever access a BBS? How about 1200 baud bliss with an xmodem transfer of the latest leet ezine from across the country via a toll-free PBX or some magical tones? If not that’s cool too, we’ve got just the thing for you. How about a multiplayer text adventure, the predecessor to modern day MMORPGs? That’s right, the Hak5 BBS is up and running so telnet on over to bbs.hak5.org, port 23 of course, and check out the door games. We’re running an active game of Legend of the Red Dragon as well as dopewars, pimpwars, food fight, and more.

Darren cracks open the pineapple and demos Jasager. He even pronounces it correctly this episode. In our controlled environment we go into how the system works, the interface, setting it up, and the future of the project. We’ll be building one from scratch on 405, then stay tuned for an interview with developer Robin Wood from this years Toorcon in San Diego. You can read up on Jasager and get yourself a fresh tarball at Robin’s site.

Speaking of Toorcon, if you’re going and wanna meetup for a drink or say hi and grab some stickers be sure to follow one of us on Twitter. You can find us all at @hak5

    I thought the blurry issue was taken care of as of episode 4×3 :(

  • Forest 6 years ago

    btw FIRST! and.. despite the blurryess, good show ;)

  • great show, been watching for long time , just wondering what ever happened to the other cast members or others who participated in the earlier shows, just wondering. Anyways glad to see show back on , nice addition with Shannon, she’s pretty hot. once again great show and many thanks for all the cool knowledge you kick down to those like me wanting to learn.

  • Good show, however why use Python, you were hacking .net, why not use PowerShell ;)

  • Great show! Stay away from Becks Light, might as well be drinking your own urine! Good tech segment Chris, way to represent SecuraBit.com! Looking forward to more shows….that is all….

  • miljenko 6 years ago

    uh, so soon the ep comes. yeeah
    gona dl it.
    cant wait for pineapple :D

  • a little blurry. but other then that another great episode.

  • Sorry about the blurryness. It’s still a big improvement over 401/402 but I know it’s not up to broadcast standards yet. We’re getting close to our HD goals so a big thanks to all that have donated for stickers. I’ll throw a sharpening filter on 404 and onward. Not a solution, more of a band-aid.

    Show Idea:
    As a follow-up to the BBS/Lord segment, how did you guys install a bbs server? I would love to run one of these… .ah the good ol days!

  • timmay313 6 years ago

    Setting up a BBS would make a great segment… reminds me of getting in trouble for being on the BBSs and IRCs during keyboarding in highschool. Love the beer stine! where can i get one? not really a becks fan but guiness is my beer!

  • like the new bbs system already really great been trying it out

  • This season is turning out to be the best yet! Keep up the great work!

    Technically what you guys are doing is not reverse engineering it is decompiling. (reverse engineering is classified as fair use and can be used to create and distribute competing software, but decompiling can not)

  • goarilla 5 years ago

    a little offtopic

    just an idea, i don’t know if this would be the right place
    but wouldn’t it be nice if there was a file-size indicator next to the download
    buttons you know something like:
    mp4 [320 mb] xvid [240 mb ] …

    a lot of people in first and especially 2nd or 3rd world countries still
    have to deal with monthly download volumes.

    and well if i see mp4 i usually think mp4 avc aka x264 which can be like 40% of the size of the xvid file without noticeable quality degradation

  • dingo420 5 years ago

    you should normalize your volume. love the show!

  • Just let everyone know, telnet bbs.hak5.org doesn’t work anymore they have must took it down. Yes, telnet still works in windows 7 you just have to enable it by going to (Start > Control Panel > Programs And Features > Turn Windows features on or off > Check Telnet Client > click OK)
