office metadata and forensics

A post over at SecurityFocus went over Microsoft Office forensics and some things to do to enhance security, most notably privacy. Because Office is so universally used, I’ve found that many people, techie and non-techie both, want to put their heads in the sand about issues with Office. They just don’t want to hear about the issues, even as malicious persons have begun poking at the apps and more and more data is disclosed on the web and search engines.

I’ve long wanted a concise and listed set of items to check on and change when dealing with metadata in MS Office Word documents. Now I have it!

Update: Here is another link dealing with pesky lingering Office data that shouldn’t be there.

I certainly cannot condone evading firewalls and other protections in the workplace or otherwise, since I’m one of those guys trying to stop these people, but these techniques can be useful not only for times when you want it, but also for knowing what people might be doing so that I can stop it. In addition, some of these techniques have the side benefit of being more secure, such as when I am at a hotspot and wanting to make connections privately to public sites.

vnc auth vulnerability

This is an awesome tutorial for examining and finding and exploiting the latest RealVNC Auth Vulnerability. I have a link to a scan tool that scans for this, and I have to find it. I suppose Metasploit will have this packaged already or soon. The fun thing about this is that I imagine most IT shops do not upgrade all their old VNC instances very much and either just use the same executable stored locally or always download a new one. I would bet many admins are still blissfully ignorant of this issue, and thus still have many vulnerable installs still sitting around. I consider this a must-have scan for any VNC instances found on a target network.

php security tools and tips

PHP has its share of issues and vulnerabilities. Honestly, it is the weak point of the LAMP architecture because of the potential for misconfigurations and insecure issues. The follow links go into an entry in the SANS Top 20 and the top 5 PHP security settings.

Since I use PHP I wanted to post this site with some PHP security tips from SANS.

And this is another nice list of php security issues and configurations.

Spike is a php auditing tool that I totally have to try out sometime soon.

rain forest puppy

Every now and then I go on a stream-of-linkage romp through blogs and security sites. Check out a site, head to the links, start spidering out and repeat. Well, today I brushed through the Nomad Mobile Research Center where I found a lot of 404 links to various people who were big in the security industry years ago. I then came across Rain Forest Puppy’s site and memorandum.

I’ve just finished reading The Cuckoo’s Egg by Cliff Stoll. The book details some of the early hacking attempts in a very new network of computers and systems and open sharing of information back in the mid-to-late 1980s, a time when I was just discovering Atari and Nintendo and Arcade gaming. In looking at the landscape of the time, of computing, networking, and security itself, things have much changed…I mean, DRASTICALLY changed since then. And I can see how people take values from back then and futiley fight the good fight for years and years, even when the time of those networks and openness are gone. The openness and phreaking got replaced with coding and open source and free tools and grassroots hacking…and today, we have commercialization of security.

I read RFP’s memo on his site and realized that this is one of the things I look for in my web romps through security links and blogs and personal sites (sites made back before “blog” was even a thought); the people who have been here already and where they are now, sometimes the dusty relics of long-forgotten websites or stories of how people have moved on, grown up, lost faith, or become part of the commercialization. The Internet and computing are still changing so much, and security even more. In 5 years from now, I could be like them or perhaps just part of the commercialization. Either way, I feel that this sort of web-trotting into the lives of other security persons from the present and past gets back to where the real security happens (or happened), where the real culture of hacking and security lies…not in the Symantecs and Microsofts of the world, but rather in the continued traditions of Black Hat and Defcon and the smaller underground groups of hackers (although slightly less underground than 5-10 years ago).

To anyone that feels like RFP, I just have to say that that kinda just happens, especially when you have a youth-fueled culture in the midst of a brand new, rapidly changing frontier like the Internet and networking. Things change so rapidly, people grow up and out of their hacking 24/7 mindsets, get married, move on in life, and into more conservative affairs. This happens, but it does not take away from the grassroots, “pure” hacking and security that has come before and still happens now.

I will say it is interesting running over sites of people whose names I know as part of the hacker scene, but their sites are outdated. Sometimes you see a resume or a post about where they’ve gone or what they were doing when their site got dusty. Then I realize just how weird the net is. Some sites disappear in moments, others, stick around on servers for years, decades. Just sitting there, waiting, listening, maybe logins have long been since forgotten and the servers just whirr away diligently maintaining their uptime. I’ve seen this in the early gaming scenes in Quake where clan pages are still sitting in cyberspace, waiting for really nothing. Links, images break over time, and they look like those old rusting cars you can find in overgrown pastures…

Some site designs I liked (for future reference): jexe and guninski. I would love a throwback design even if that throws back to a time before I was into computers, but there is something nearly romantic and appealing to the idea of a nighttime black world with the only light the soft greenish glow of a computer terminal illuminating the outline of a determined hacker…

the noc water cooler topics

It is interesting to see the trend of what is hot in security and networking and sysadminness. The turn of the millenium brought in virtualization, and a few years ago Metasploit broke onto the scene in a big way. Wireless and mobility have been amazingly hot in the last 6 years as well. And now that web apps are being developed by everyone, web app testing and security is catching up. In all of this, I thought it would be nice to keep track, for my own purposes, the hot topics at periodic times of the years just to see where things are moving and shaking.

1. web application / layer 7 security / fuzzing – driven by a huge focus in the past 8 months on MS Office vulnerabilities and browser exploits.

2. mobility – driven by laptops being used and lost in the field, prompting a huge number of disclosures of lost information that questionably should not have been outside the corporate/gov’t environments anyway.

3. disclosure and identity theft – Just about everyone has been joining the disclosure bandwagon whether they like it or not, from the VA, Deloitte and Touche, and many universities (poor edu’s will always have a tough open vs secure battle). This will only get worse and hopefully soon the media stops waving each one that happens.

5. botnets and ddos – Blue Security wanted to beat spammers by spamming them. Instead, Blue Security got DDoSed so hard, they are now out of business and have thrown in the towel. Botnets have been widely reported in the past couple years, but they still seem to grow and remain huge and potent.

4. wireless – wireless is just waiting to blow up, with hotspots getting more common and big companies with secret plans on widespread wireless for the masses. Since wireless is still hugely exploitable and fun to mess with, this is just waiting for a huge lashback and a huge outbreak in personal systems being exploited over wireless. Home users haven’t been this vulnerable to being rooted since NAT was hardly used on broadband connections. This is an area that is also just waiting to explode with use and companies and wirespread access.

Mentions and tools: Metasploit is still hot and HD Moore is one of the biggest names in security right now; virtualization is still hot; Office and IE are getting hammered with exploits which is keeping Microsoft very busy; LiveCDs are all over the place now, joining the awesome Knoppix (BackTrack owns).

tunnel vnc over ssh

This article explains how to tunnel VNC traffic over SSH to create a secure means to connect back to your home computer from anywhere. I’ve always wanted to do this and have yet to do it. Basically this is just about poking a hole in your home firewall, setting up an SSH server, and doing a port forware on that SSH server to the internal VNC-equipped system. Nothing rocket-science here, and the technique can be used for pretty much anything. We actually used a similar technique in my old job before we moved to a full VPN solution.
