That was until recently when I did some work with Chris Truncer who had us set it up as part of a red team test. That was the point I had to get down and understand the actual inner workings. Luckily Chris is a good teacher and the concept is fairly simple when it is broken down into pieces. https://digi.ninja/blog/domain_fronting.php https://digi.ninja/blog/cloudfront_example.php Sat, 02 Nov 2019 00:00:00 +0000 This post accompanies the post A 101 on Domain Fronting and in it we are going to setup both a site to use for domain fronting and then a fronted site. https://digi.ninja/blog/cloudfront_example.php https://digi.ninja/blog/hiding_bash_history.php Wed, 10 Jan 2018 00:00:00 +0000 Have you ever logged in to a box, started running commands, and then remembered the bash history will be logging everything you run.

I've mentioned it to a few Git loving developers who all claimed that it is obvious and that loads of people are already using it, but, as we regularly see keys in GitHub, I'd guess that its a case of what people know they should be doing verses what they are actually doing. The trick uses Git hooks to catch content pre-commit and block anything that it thinks is suspicious. https://digi.ninja/blog/git_hooks.php https://digi.ninja/blog/enable_right_click.php Tue, 18 Oct 2016 00:00:00 +0100 I've spent the day testing an app which disables the right click context menu, this makes testing tricky so I found a one liner which I could drop into the browser console to re-enable it for me. https://digi.ninja/blog/enable_right_click.php https://digi.ninja/blog/missing_a_vuln.php Wed, 13 Apr 2016 00:00:00 +0100 Asking the question, when it is acceptable to miss a vulnerability on a test. https://digi.ninja/blog/missing_a_vuln.php https://digi.ninja/blog/ee_no_password_change.php Tue, 05 Apr 2016 00:00:00 +0100 Trying to understand why the EE web portal doesn't have a password change feature. https://digi.ninja/blog/ee_no_password_change.php https://digi.ninja/blog/xss_through_csrf.php Sun, 04 Jun 2017 00:00:00 +0100 A short guide to exploiting POST based reflected XSS using CSRF and iframes. https://digi.ninja/blog/xss_through_csrf.php https://digi.ninja/blog/interactive_pentesting.php Sun, 04 Dec 2016 00:00:00 +0000 A write up of my recent experiences of getting clients involved during testing. https://digi.ninja/blog/interactive_pentesting.php https://digi.ninja/blog/hacking_nasl.php Sun, 03 Dec 2017 00:00:00 +0000 A short howto on removing the obfuscation added to non-default passwords by Nessus. https://digi.ninja/blog/hacking_nasl.php https://digi.ninja/projects/pipal.php#neofriends Mon, 02 Mar 2015 00:00:00 +0000 Pipal analysis of of a password dump from the Neofriends dating site. https://digi.ninja/projects/pipal.php#neofriends https://digi.ninja/projects/pipal.php#lizard Wed, 21 Jan 2015 00:00:00 +0000 Pipal analysis of 13,000 passwords from the Lizard Squad dump. https://digi.ninja/projects/pipal.php#lizard https://digi.ninja/projects/pipal.php#minecraft Wed, 21 Jan 2015 00:00:00 +0000 Pipal analysis of 1800 passwords dumped from Minecraft https://digi.ninja/projects/pipal.php#minecraft https://digi.ninja/projects/pipal.php#datingsite Sat, 27 Dec 2014 00:00:00 +0000 Pipal analysis of a password dump from a dating site. https://digi.ninja/projects/pipal.php#datingsite https://digi.ninja/blog/sony_hack.php Sony were hacked, it was bad.

Till now, each time I wanted to reuse an issue I've had to open a new browser and go back to find the old project where the issue was used then copy and paste it into the new project, that is a real pain to do. So I finally bit the bullet and created a MediaWiki VM. Rather than mess around with manually copying all my issues across I developed this little script to automate it. https://digi.ninja/projects/mediawiki_dradis_import.php https://digi.ninja/blog/reproduce_report.php Three times in the past few months I've been asked by clients to retest previous findings to see if they have been successfully fixed. One of the reports I was given was one I'd written, the other two were by other testers. For my report I couldn't remember anything about the test, reading the report gave me some clues but I was really lucky and found that I'd left myself a test harness in the client's folder fully set up to test the vulnerability. One of the other two was testing for a vulnerability I'd never heard of and couldn't find anything about on Google. I finally tracked down the original tester and it turns out there is a simple tool which tests for the issue and one command line script later the retest was over. The final issue was one that I knew about but had a really good write up that, even if I'd not heard of it, had a full walk through on how to reproduce the test. https://digi.ninja/blog/reproduce_report.php https://digi.ninja/blog/rip_v2.php In part one of this series, Exploiting RIP, we set up a GNS3 lab with RIPv1 and managed to exploit it by injecting a fake route into the network. As a way to protect against this, RIPv2 can use authentication to try to stop unauthorised routes being added to the system. From what I've read, authentication was not added to RIPv2 as a security mechanism but as a way to prevent routes from accidentally being added when incorrectly configured routers are added to the network. In this post I'll work through changing the lab from version 1 to version 2 and then enabling the different levels of authentication. At each stage I will show weaknesses in the system and ways to abuse them. https://digi.ninja/blog/rip_v2.php https://digi.ninja/projects/pipal.php#tesco A Pipal analysis of the recent Tesco password disclosure. https://digi.ninja/projects/pipal.php#tesco https://digi.ninja/blog/gmail_dos.php If anyone was watching my Twitter feed over the last few days you'll have seen me complaining about my Gmail account being down. It wasn't down completely, I could still access the web interface and read all old mails but hadn't had any new emails in since 4AM on Thursday. I have various other mail accounts, some Gmail, some not, so I tried sending myself mails from those account to see if things were broken or whether I had just become very unpopular. None of the mails got through. I also tested sending emails out and none of those worked either so there was definitely a problem. By Friday lunchtime I'd had a couple of mails but nothing much so I figured I'd better do some digging and get it fixed. https://digi.ninja/blog/gmail_dos.php https://digi.ninja/blog/rip_v1.php In this lab I'm going to look at RIPv1, probably the most basic routing protocol. As with the VLAN labs I'm building this one in GNS3 and linking it to a Virtual Box machine running Debian. The plan is to build a network with three routers all using RIP to sync their routing information. I'll then use the attacking box to inject a fake route into the network and so divert traffic away from its real target. If you are not familiar with RIP it is hop based system where each hop is a unit and traffic is routed across the shortest number of hops. https://digi.ninja/blog/rip_v1.php https://digi.ninja/blog/abusing_dtp.php In the first two parts of this dig into layer 2 I covered how to set up a lab using GNS3 and VirtualBox and then adding and interacting with VLANs. In this part I want to look at using Cisco's Dynamic Trunking Protocol - DTP - to change the state of a port from access mode to trunk mode to allow us to gain access all the VLANs on the network. The previous link gives a more thorough overview of DTP but in summary, it is a protocol developed by Cisco to allow devices connected to a switch negotiate whether they need their port to be in trunk or access mode. It is enabled by default on all ports so has to be deliberately disabled by an admin to turn it off. Ports default to access mode leaving devices such as switches, which need a trunk port, to request it. A port can be changed from one state to the other through a single DTP packet and there is no authentication, this makes it great as an attacker as you can easily switch your port to trunk mode on any switch which has DTP enabled. https://digi.ninja/blog/abusing_dtp.php https://digi.ninja/blog/gns_vbox_vlan_lab.php Adding VLANs to the GNS3/VirtualBox Lab - In this post I show how to add VLANs to the lab and how to move between them on the switch. I then show what can happen if you get on to a trunk port and get to control your own VLAN tagging. https://digi.ninja/blog/gns_vbox_vlan_lab.php https://digi.ninja/blog/gns_vbox_basic_lab.php Integrating GNS3 and VirtualBox - Having come from a development background rather than a sys-admin one, my knowledge of layer 2 is not as good as I'd like it to be so I've decided to do something about it. I've always been interested in VLANs and the idea of bypassing them so thought that would be a good place to start. This is the first part of a series building a lab to test out different layer 2 attacks. https://digi.ninja/blog/gns_vbox_basic_lab.php https://digi.ninja/projects/sitemap2proxy.php Sitemap2Proxy takes the sitemap published by a web app and requests each page through your specified proxy. This release adds response code stats to the output. https://digi.ninja/projects/sitemap2proxy.php https://digi.ninja/blog/modsecurity_lab.php I've been meaning to build a ModSecurity lab for a while and seeing as I had some free time I decided it was about time to do it and to document it for everyone to share. The lab I built uses an up-to-date version of ModSecurity with a rule set taken from the SpiderLabs github repo and, so there is something to attack, I've included DVWA. https://digi.ninja/blog/modsecurity_lab.php https://digi.ninja/projects/cewl.php Version 5.0 of CeWL adds proxy and basic/digest authentication support along with a few small bug fixes. https://digi.ninja/projects/cewl.php https://digi.ninja/projects/ivmeta.php ivMeta is based on information in this article on finding meta data in iPhone videos. It will attempt to pull the following bits of information from an iPhone video: * Maker - should always be Apple * iOS Software version * Date video was taken * GPS co-ords where video was taken * Model of phone https://digi.ninja/projects/ivmeta.php https://digi.ninja/blog/zap_fuzzing.php The following article is part two of my introduction to ZAP and testing WebSockets, in this episode I'll cover fuzzing. If you've not used ZAP before I suggest you look at some of the official tutorials first - ZAP home page, Videos. You can find my first part here OWASP ZAP and Web Sockets. The testing is being done against a small WebSockets based app I wrote called SocketToMe which has a few published services along with a few unpublished ones. In this article we are going to look at one of the published ones and try to identify some of the unpublished ones. The first feature I'll investigate is the number guessing game. Here the system picks a random number between 1 and 100 and you have to guess it. I'm going to cheat and see if I can get ZAP to play all 100 numbers for me to go for a quick win. https://digi.ninja/blog/zap_fuzzing.php https://digi.ninja/blog/zap_web_sockets.php With the slow uptake of HTML5, WebSockets are going to start being seen in more and more applications so I figured I'd better learn how to test them before being put in front of them on a client test and having to learn as I went along. I figured the best way to do this was to build a very simple application then throw in a proxy and see what happened. Unfortunately my proxy of choice, Burp Suite, currently doesn't handle WebSockets so I had to look for one that did. The only one, and this is their claim, that does in the OWASP Zed Attack Proxy, or ZAP for short. I'd been meaning to learn how to use it for a while so this seemed like the perfect opportunity. If anything in here is wrong, please get in touch and I'll fix it, I'm learning as I go along so may well be doing the odd thing wrong however it does all seem to work. I started by writing a small WebSocket based app which I called SocketToMe which has a few basic services, chat, a number guess game and a couple of other features. I figured I'd start with interception then have a look at fuzzing. https://digi.ninja/blog/zap_web_sockets.php https://digi.ninja/projects/sockettome.php SocketToMe is little application I wrote to go along with my blog post on testing WebSockets. It combines chat, a simple number guessing game and a few other hidden features. The app is in two parts, the WebSocket app and a web page to access it. The whole lot is written PHP and is the first WebSocket work I've done so don't look on it as an example of how to do things. https://digi.ninja/projects/sockettome.php https://digi.ninja/blog/pipal_goes_modular.php Pipal now has a modular structure allowing you to write your own Checkers and Splitters, this is a brief introduction to how they both work. https://digi.ninja/blog/pipal_goes_modular.php https://digi.ninja/projects/pat_to_pass.php This months BruCON 5x5 project came from an idea sent to me by a friend after I released Passpat. Passpat takes passwords and tries to find keyboard patters in them, Pat to Pass is almost the opposite, it takes observed key presses and tries to convert them to potential passwords. The project in its current state is more a proof of concept and sample code which hopefully can be taken forward to be turned into something practical by someone who has better skills at handling very large lists of data. https://digi.ninja/projects/pat_to_pass.php https://digi.ninja/projects/spidering_spideroak.php Spidering SpiderOak - By looking at the differences between responses it is possible to enumerate valid account names and then shares on the SpiderOak network. This post covers how I researched this, the findings and how it could be fixed. https://digi.ninja/projects/spidering_spideroak.php https://digi.ninja/projects/passpat.php It is generally accepted that most passwords in common use are based on dictionary words however, some people decide to use keyboard patterns instead and to try to spot these I've created Passpat. Passpat uses data files containing the layouts of common keyboards to walk each word through the keyboard and score the word based on how close it is to being a pattern. For now I'm taking pattern to mean keys which are next to each other, while qpalzm is a pattern picking something like that up is currently out of the scope of this project. https://digi.ninja/projects/passpat.php https://digi.ninja/projects/bin_gen.php While working on a new project I needed a way to create files containing binary data which I could control, for example all bytes from 0 to 255 in order or just a block of 10 0x03's, so I wrote bin_gen. There are loads of other ways to do this, especially in Linux, but for me this is quick and easy and I don't have to think to use it. https://digi.ninja/projects/bin_gen.php https://digi.ninja/projects/tracker_tracking.php When doing reconnaissance on clients it is often useful to try to identify other websites or companies who are related to your target. One way to do this is to look at who is managing the Google Analytics traffic for them and then find who else they manage. There are a few online services which do this, the probably best known being ewhois, but whenever you use someone else's resources you are at their mercy over things like accuracy of the data and coverage, especially if you are working for a small client who hasn't been scanned by them then you won't get any results. This is where my tracker tracking tool comes in. The tool is in two parts, the first uses the power of the nmap engine to scan all the domains you are interested in and pull back tracking codes, these are then output in the standard nmap format along with the page title. I've then written a second script which takes the output and generates a grouped and sorted CSV file which you can then analyse. https://digi.ninja/projects/tracker_tracking.php https://digi.ninja/blog/brucon_5x5.php During BruCON 2012 the organisers announced a very generous competition, they had collected 25,000euro and were going to offer it in 5k euro chunks to five lucky hackers. The condition was you had to submit a proposal saying why you needed the cash. You can read more about it on the BruCON Blog. I've very please to say that I was one of the chosen hackers so want to document what I'm going to do with my share of the cash. https://digi.ninja/blog/brucon_5x5.php https://digi.ninja/projects/ip_camera_finder.php When I bought an IP camera to watch by daughters cot I didn't expect to end up writing tools to find others around the world, I also didn't expect it to be so poorly secured. https://digi.ninja/projects/ip_camera_finder.php https://digi.ninja/blog/report_writing_comp.php A lot of conferences have CTFs but how about testing people's report writing skills as well? This post contains some ideas I've had to run a competition which would test report writing skills. https://digi.ninja/blog/report_writing_comp.php https://digi.ninja/metasploit/mysql_file_enum.php Tim Tomes wrote a blog post on enumerating directories and files through a MySQL connection, this module automates that process. https://digi.ninja/metasploit/mysql_file_enum.php https://digi.ninja/blog/dns_wildcard_recon.php I recently did a test against a company and in the debrief they asked how I managed to enumerate so many of their subdomains as they were using a wildcard DNS setup and the previous tester had commented that it prevented DNS enumeration. When I explained to them how the wildcard only obscured valid domains they had a few choice words for the previous tester and I figured it would make a nice little blog post. https://digi.ninja/blog/dns_wildcard_recon.php https://digi.ninja/blog/hakin9_spam_kings.php About once a fortnight I get a request to write an article for Hakin9 or one of its sister publications, this article details my attempts to stop this spam. https://digi.ninja/blog/hakin9_spam_kings.php https://digi.ninja/blog/corelan.php I've just got back from BruCON 2012 where I started the week with the Corelan Live - Win32 Exploit Development Bootcamp. A lot of people asked about the course and what it covered so I've put this together. https://digi.ninja/blog/corelan.php https://digi.ninja/projects/sitemap2proxy.php When doing a web app test you usually end up spidering the site you are testing but what if the site could tell you most of that all about theirhout you going hunting for it. Bring on sitemap.xml, a file used by a lot of sites to tell spiders, like Google, all about their content. This script takes that file and parses it to extract all the URLs then requests each one through your proxy of choice (Burp, ZAP, etc). Now this won't find anything that isn't mentioned in the file and it won't do any brute forcing but it is a nice way to identify all the pages on the site that the admins want you to know about. https://digi.ninja/projects/sitemap2proxy.php https://digi.ninja/projects/cewl.php Version 4.3 of CeWL adds result sorting by word count, with optional display of the count, also various bug fixes. https://digi.ninja/projects/cewl.php https://digi.ninja/karma/ Hostapd was recently updated to version 1.0 so I've brought the Karma patches up-to-date. This release contains a fully patched source tarball and a patch file if you want to apply it to your own source. I've also added a mention of the hostapd_cli app which you can use to control hostapd once it is running. https://digi.ninja/karma/ https://digi.ninja/blog/zodiac_passwords.php I was wondering why dragon and monkey come up so often in Pipal analysis of password lists and it got me wondering if it was to do with Chinese signs of the zodiac so just as an experiment I've just added checking for both Western and Chinese zodiac signs to Pipal. I ran it against the 1 million eHarmony passwords I've got and it looks like they do play a small part in some people passwords. https://digi.ninja/blog/zodiac_passwords.php https://digi.ninja/blog/group_password.php Did you know Linux groups can have passwords? I didn't but I do now, this is how you set them up. https://digi.ninja/blog/group_password.php https://digi.ninja/projects/twofi.php Twofi takes keywords and usernames and collects tweets based on these terms. It then extracts individual words and uses them to create a custom word list. https://digi.ninja/projects/twofi.php https://digi.ninja/blog/web_frameworks.php Are secure web frameworks reducing long term security? Why I think developers should always think about security, even when someone else is taking care of it for them. https://digi.ninja/blog/web_frameworks.php https://digi.ninja/projects/cewl.php Turns out that the spider I'm using for CeWL only checks for links in anchor tags where the href uses double quotes which means some links will have been missed. This release fixes that bug and adds the ability to do a depth of 0 search which lets you scan a single page. https://digi.ninja/projects/cewl.php https://digi.ninja/projects/breaking_in_part_2.php The second part of my write up of the conclusions I've taken from my Breaking In data. This part looks at the qualitative answers given which give some meaning behind some of the stats. https://digi.ninja/projects/breaking_in_part_2.php https://digi.ninja/projects/breaking_in_part_1.php This post, along with part two coming soon, is an accompaniment to my BSides slides and the raw data which I published the other day. Here I try to summarise the results and add my commentry to them. https://digi.ninja/projects/breaking_in_part_1.php https://digi.ninja/projects/breaking_in_bsides.php At BSides London I presented the findings from the Breaking in to Security survey, here are my slides and a link to the data collected so far. https://digi.ninja/projects/breaking_in_bsides.php https://digi.ninja/projects/breaking_in_interim.php Seeing as I had over 200 responses to the "Breaking In" survey in just 5 days I've plucked out a couple of interesting stats from the responses and posted them to whet your appitite. https://digi.ninja/projects/breaking_in_interim.php https://digi.ninja/blog/owasp_leeds.php The story of how I analysed a new IP web camera and found how it automatically tried to punch a hole through my firewall and register itself with dynamic DNS server to tell the world it was there. The slides also contain a bonus talk covering my blog post and project on 'Whats in Amazon's buckets' https://digi.ninja/blog/owasp_leeds.php https://digi.ninja/projects/breaking_in_1.php This is my attempt to collect enough data to be able to answer the eternal question, 'How do I get started in Information Security?'. I've put together a questionnaire which I'll summarize the answers from and hopefully present at conferences and also summarise here on the site. https://digi.ninja/projects/breaking_in_1.php https://digi.ninja/projects/zonetransferme.php Ever found yourself in a position where you have to teach or explain DNS zone transfers but not had a domain to run the transfer on? This domain is set up to allow transfers and contains plenty of information to work with. I've also explained how I would interpret the information. https://digi.ninja/projects/zonetransferme.php https://digi.ninja/projects/pipal.php Pipal analyses a cracked password list to help analysts spot patterns.
