This is the first one on decrypting WPA/2 PSK traffic. The second will cover some tricks/scripts for rogue access-points. If you are keen on learn further techniques or advancing your wifi hacking knowledge/capability as a whole, please…
Windows Domain Privilege Escalation : Implementing PSLoggedOn in Metasploit (+ a bonus history module)
There are multiple paths one could take to getting Domain Admin on a Microsoft Windows Active Directory Domain. One common method for achieving this is to start by finding a system where a privileged domain account, such as a domain admin, is logged into or has recently been logged into. Once access to this system has been gained, either stealing their security tokens (ala Incognito or pass-the-hash attacks) or querying…
Analysis of Security in a P2P storage cloud
A cloud storage service such as Microsoft SkyDrive requires building data centers as well as operational and maintenance costs. An alternative approach is based on distributed computing model which utilizes portion of the storage and processing resources of consumer level computers and SME NAS devices to form a peer to peer storage system. The members contribute some of their local storage space to the system and in return receive “online backup and data…
Google Docs XSS – no bounty today
A few days ago, during one of those nights with the baby crying at 2:00 am and the only thing you can do is to read emails, I realised that Gmail shows the content of compressed files when reading them in Google Docs. As often is the case at SensePost, the “think evil ™” came to me and I started to ponder the possibilities of injecting HTML inside the file…

Adolescence: 13 years of SensePost
Today was our 13th birthday. In Internet years, that’s a long time. Depending on your outlook, we’re either almost a pensioner or just started our troublesome teens. We’d like to think it’s somewhere in the middle. The Internet has changed lots from when SensePost was first started on the 14th February 2000. Our first year saw the infamous ILOVEYOU worm wreak havoc across the net, and we learned some, lessons on…
Poking Around in Android Memory
Taking inspiration from Vlad’s post I’ve been playing around with alternate means of viewing traffic/data generated by Android apps. The technique that has given me most joy is memory analysis. Each application on android is run in the Dalvik VM and is allocated it’s own heap space. Android being android, free and open, numerous ways of dumping the contents of the application heap exist. There’s even a method for it…
Client Side Fingerprinting in Prep for SE
On a recent engagement, we were tasked with trying to gain access to the network via a phishing attack (specifically phishing only). In preparation for the attack, I wanted to see what software they were running, to see if Vlad and I could target them in a more intelligent fashion. As this technique worked well, I thought this was a neat trick worth sharing. First off the approach was to…
