PaulDotCom Security Weekly - Episode 254 for Thursday August 11th, 2011.

Guest Tech Segment Mini-Marathon: A Special Night with Trustwave's SpiderLabs!

Amazingly True Stories of Real Penetration Tests with Rob Havelt & Wendel Henrique

7:30 PM EDT / 6:30 PM CST

Rob Havelt, director of penetration testing, and Wendel Henrique, security consultant, will present Earth vs. The Giant Spider: Amazingly True Stories of Real Penetration Tests.

Rob is Director of SpiderLabs' Penetration Testing Practice, where he oversees all aspects of network and infrastructure security testing and wireless network testing. Formerly a bourbon-fueled absurdist, raconteur, and man about town, Rob is currently a sardonic workaholic occasionally seeking meaning in the finer things in life — Rob is, and will always be, a career hacker.

Wendel is a consultant for pen testing at Trustwave, where he has discovered vulnerabilities across a diverse set of technologies including webmail systems, wireless access points, remote access systems, web application firewalls, IP cameras, and IP telephony applications.

  1. The unique opportunity to see real, interesting, uncommon and some non- trivial attacks that can't be found by automated tools.
  2. Culled from the more than 2300 penetration tests delivered last year by SpiderLabs - only the coolest and freakiest were selected to present at DEFCON 19.
  3. By the end of this presentation, they hope to have the you thinking about systems and applications that organizations use every day, and how they may be used against them.

The attacks are:

  • Do you want Fries with that Hack?
  • One PBX Will Rule Them All Hack.
  • The Inside-Out VPN Hack.
  • The Island Nation and Port 0 Hack.
  • The Caucasian-Asian Love Hack.
  • In Soviet Russia Hackers Monitor You Hack.
  • Oracle and The New Tool Hack

Traps of Gold by Andrew Wilson & Michael Brooks

8:00 PM EDT / 7:00 PM CST

Traps of Gold is a study which examines the offenses and defenses of web application security and introduces "maneuverability" - a new strategy for fighting back.

Andrew specializes in application security assessment, penetration testing, threat modeling and secure development life cycle. Andrew is active as a leader of the Phoenix OWASP and is a Microsoft MVP in Windows Azure. He is not a Cabal member.

Michael works for SiteWatch, where he composes exploit code, which he considers a challenging and privileged art form. Michael is on PaulDotCom because he believes secure software is a luxury that should be shared. He's also in the April - June 2011 edition of the Google Security Hall of Fame.

Speaking with Cryptographic Oracles by Dan Crowley

8:30 PM EDT / 7:30 PM CST

Speaking with Cryptographic Oracles is a discussion of methods for finding and exploiting encryption, decryption, and padding oracles from a black box perspective.

Dan is an Application Security Consultant for Trustwave's SpiderLabs and is particularly focused on vulnerabilities caused by a failure to account for little known or even undocumented properties of the platforms on which applications run. He especially enjoys playing around with Web based technologies and rock climbing, has been known to be a unicorn Furnace, and makes a mean chili quite worthy of a PaulDotCom post-exploitation towel.

  1. What is an Oracle?
  2. How can people really bad at math translate cihpertext into plaintext?
  3. How can this help us evade detection and prevention of web app attacks?

Stories For Discussion

Steve Holden, DefCon Talks Summary

Steve is a senior systems engineer for a U.S. Navy R&D organization in San Diego. His key research focus areas include: information technology systems, enterprise computing, computer network security, and project management. Steve is on to give us an overview of the talks he attended at DefCon 19.

Larry's Stories

Government disruptors carry pink pagers - [Larry] - Thanks to Travis Goodspeed (and others) how have hacked the GRRLtech IM-ME pink pager to do all sorts of things, now can use it to DoS government/federal law enforcement communications. First off, the communications is secured with a protocol known as Project 25 (P25), which they were able to monitor using parts from radio shack. What they were able to determine is that P25 does not use spread spectrum (and I'm guessing frequency hopping), but instead relies on metadata encoded in the transmission in order to decipher the encoded transmission. So, what happens if that metadata is interrupted? the communications cannot be decoded. In fact, it only takes a "jamming" pulse of 1/100th of a second during portions of the metadata transmission to DoS the transmission. This might be a nice thing to deploy at your home during a SHTF situation, as P25 radios are allegedly in use by every major law enforcement agency. After just reading the whitepaper, Travis was involved, as was Sandy Clark (sending hugs your way) who's talk I missed at DEFCON.

CDMA and 4G MitM'ed at DEFCON? - [Larry] - Who knows. This post claims yes, and that attacks were launched against PCs and Android devices. no mention of iPhone attacks. Honestly it makes sense, as all the moving parts exist. I did notice my phone getting dumbed down to GPRS, clicks on my calls, and some seriously delayed SMS messages. Sure it is possible, but I won;t believe it until I see proof…

…and GPRS cracked - [Larry] - Karsten Nohl will be releasing some tools (but not the keys) in order to decrypt GPRS data communications. During his research, he was able to determine that various carriers us different varieties of the A5 algorithm used with GSM networks, and some had no encryption at all. The hardware needed? Just some older, cheap, readily available phones.
