Larson to use their Lab facilities.http://www.estrellamountain.eduJoey Prestia (joey at linuxamd.com) will be supporting the PLUG FEST, as we delve into the exciting area of Linux Security.Saturday November 15th, 2008 - Noon Until 3:30We will bring targets for your practical exploits and scanning - and go over the original presentation materials for each lab - depending on the time available.Presentation Materials are available for review (if you just found us) at: http://www.scribd.com/doc/6680231/Hack-FestIt's suggested that people plan:1) Develop and bring a machine with a good distribution or LiveCD's tested to work.  [THIS MONTH We will have the Estrella Mountain Network and LAB Machines to use!]2) Social Engineer team members and choose one or two areas to concentrate on.  TEAMS usually always succeed most quickly -  as one person reviews the materials while the other does the lab.Again this is a practical lab - not a hacking/cracking demonstration.This format is presented for computer professionals, linux security professionals and linux users and is in no way an advocation of cracking, disrespect for private property or illegal activities.A disclaimer signature and email address will be required at the door.See you all there!Obnosis.com |  http://en.wiktionary.org/wiki/Citations:obnosis |http://www.urbandictionary.com/define.php?term=obnosis (503)754-4452________________________________________________________________From: lisakachold at obnosis.comTo: plug-discuss at lists.plug.phoenix.az.usSubject: RE: HackFest Series: "Is it safe yet" or SSH Buffer Overflows and You - CHECK YOUR VERSIONSDate: Thu, 30 Oct 2008 15:38:46 +0000SSH Exploits are currently available in various forms:1) General Stack Based exploits.  Also called Boundary Protection BOE's.  Check your version.Most older versions have been fixed:http://secunia.com/advisories/search/?search=ssh+buffer+overflow2) Protocol 1 exploits. (Check your Version) configure /etc/ssh/sshd_config to use Protocol 2.3) Kerberos exploits - authentication when compiled against various insecure Kerberos. Check your version; these affect older versions of SSH or unpatched systems.Description of exploit: http://kerneltrap.org/node/1604) Random PRNG entropy SSL/SSH - announced in 2006 by a team of university students, this problem with random number generation allows the attacker to guess the key generation and affected nearly all versions of SSL/SSH - including routers/switches/firewalls and custom mail applictions.Debian/Ubuntu descriptions from CERT:http://www.debian.org/security/2008/dsa-1571" http://www.debian.org/security/2008/dsa-1576" http://www.ubuntu.com/usn/usn-612-1 http://www.ubuntu.com/usn/usn-612-2 http://www.ubuntu.com/usn/usn-612-3 http://www.ubuntu.com/usn/usn-612-4 http://www.ubuntu.com/usn/usn-612-5http://www.ubuntu.com/usn/usn-612-6 http://www.kb.cert.org/vuls/id/9252115) Challenge and Response - allows escalated privileges upon overflow of the buffer:Description and versions affected:http://www.juniper.net/security/auto/vulnerabilities/vuln5093.htmlExample Script that exploits SSH challenge response [see no die there then the overflow payload?]:http://www.milw0rm.org/exploits/6804BlackHat Training:http://www.blackhat.com/html/bh-europe-07/train-bh-eu-07-ss-el.htmlMetasploit (comes setup on BackTrack) includes a few examples for SSH exploit training:http://www.metasploit.com/NOTE: This information has been intentionally obfuscated using intellectualism to filter out the less evolved crackers in favor of providing security tools to responsible professionals systems hackers [ builders troubleshooters and ethical users].http://wapedia.mobi/en/Obnosis |  http://en.wiktionary.org/wiki/Citations:obnosis | Obnosis.com (503)754-4452________________________________> Date: Thu, 30 Oct 2008 00:49:53 -0700> From: PLUGd at LuftHans.com> To: plug-discuss at lists.plug.phoenix.az.us> Subject: Re: HackFest Series: "Is it safe yet" or SSH Buffer Overflows and You>> Am 30.
