Interview: Marcus Ranum

You wrote The Six Dumbest Ideas in Computer Security in 2005. Now, some 3 years later, how many of your opinions still ring true? Is the security still a miserable failure?

I'm in agreement with the need to do things right the first time. Why do you think that this doesn't happen? Lazyness? Poor business decisions? Or, is it really jsut that hard to code properly to begin with!

Sure, design things right and secure from the beginning. How do you deal with situations where you don't have the ability to change/audit/secure required code, with something that is/will be essential to your business; say, for example, windows.

What are your feelings on penetration testing?

Stories For Discussion

Microsoft IE XML 0day exploit - [PaulDotCom] - I tested the one that Core released the other day, didn't work for me. This is pretty bad though, IE 0days are just a bad thing for everyone. There are so many ways to get someone to click on a link or load HTML/JavaScript, like social networking sites. I find it funny that someone I went to high school with, who, well, lets just say wasn't top of the class, clicks on stuff. Then those that are friends with her on Facebook get emails with links, that contain malware. Nice! Some things never change :)

Nmap Book! - [Larry] - Now shipping in time for Christmas. Awesome book that Fyodor has promised for years. It includes all of the information that he's learned in scanning networks over the last 10 years. Sample chapters are available on nmap.org... Paul, you have a copy, please tell us what you've found valuable

Penetration Testing is Dead! - [PaulDotCom] - Thats right, penetration testing is dead. Oh hell, why don't we just come out and claim that security is dead. One can pick on any one defensive/auditing tactic, claim it dead, and say that other layers are more effective. This is bull, you need to evaluate the risk for your organization and determine which layers to implement, and how you should implement them. More on this topic in a blog post I am working on, but thats the jist of it.

One line Bash web server - [PaulDotCom] - Command line Kung Fu is important if you are a pen tester, and here's is a good example. It allows you to serve files in a directory via web server, neat! Great way to share "tools" on a pen test.

Facebook: 100 friends in 4 days - [Larry] - An interesting, if somewhat repeated, experiment. but, it just goes to show that sometimes just asking for something, and acting like you belong is often one of the easiest methods of social engineering. To me, it also speaks to the dangers of what you share on social networking sites, and who you've given access to it.

DD-WRT XSRF - [Larry] - Remote command execution, password changes, modify forwarding rules, enable remote administration...This has been tested by the author on the latest version v24-sp1, and I winder if it works on older versions. I know lots of people use DD-WRT...

Linksys WVC54GC Camera Vulnerabilities - [PaulDotCom] - I thought this was great, check out this description: US-CERT say that by delivering a specially crafted packet to the cameras UDP port 916, an attacker can make it respond with a packet that contains the majority of its system configuration, including details such as username, password, wireless ssid, WEP key, WEP password, WPA key, and DNS server. Love it!

WordPad - [Larry] - On the heels of a recent round of patches, an exploit is now circulating toe a WordPad exploit. This affects Windows 200 SP4 to XP SP2 and Server 2003 SP1 and SP2. Micorosoft claims that it does require some user interaction to get them to open the malformed document. No patches exist currently, so how do we protect? Web filter, block attachments and AV with appropriate signatures? How about IPS with some rockin' rules?

Fone Fraud Follow-up - Apparently a few more details about the Nortel system that was owned earlier this year due to default passwords being in place.

Asterisk Vulnerability, FBI Style - [Larry] - The FBI released a notice that Asterisk had a vulerabiluty that allowed fo "vishing", without releasing a lot of info, or contacting the vendor, Digium. Come to find out, Digium found the bug in March in versions 1.2 and 1.4, and fixed it for 1.6. So, two things: why hold back the info, and not contact the vendor? Second, how to patch critical systems that are expected to be up 24/7?

Netscreen Of The Dead - Firmware Attacks! - [PaulDotCom] - Awesome presentation! They reversed the Juniper Netscreen firmware, hotness. However, I find it most interesting when they describe the attacks:

  • Hidden shadow configuration file, allowing all traffic from one IP through Netscreen, and network traffic tap
  • Persistent infection via boot loader on ScreenOS upgrade
  • Javascript code injection in web console...

Geek Christmas Gifts! Don't Forget! - [PaulDotCom] - Don't forget to add you favorite security geek or just plain geek Christmas gifts. Some of the suggestions so far

Christmas Hacking Challenge - [Larry] - Here's some fun for the holidays from our good friend Ed Skoudis. I bet some of the solution to this one is some tools we've talked about on the podcast!

Spam back on the rise - [Larry] Slowly but surely, just like we talked about last week with Andre, the McColo shutdown won;t stymie the bot-herders for long. Although the article brings up some interesting points, that some botnets aren't making resurgence as it apparently becomes a business decision to abandon your botnet and start fresh when something like this happens; turns out the longer it goes, there's some diminishing returns on trying to recover your zombies.
