Introduction Ok, I have a confession to make, I have always been somewhat intrigued by egghunters. That doesn’t mean that I like to use (or abuse) an egghunter just because I fancy what it does. In fact, I believe it’s a good practise to try to avoid egghunters if you can, as they tend to […]The post Windows 10 egghunter (wow64) and more first appeared on Corelan Cybersecurity Research.
Introduction Hi all, Over the course of the past few weeks ago, I received a number of "emergency" calls from some relatives, asking me to look at their computer because "things were broken", "things looked different" and "I think my computer got hacked". I quickly realized that their computers got upgraded to Windows 10. We […]The post Windows 10 x86/wow64 Userland heap first appeared on Corelan Cybersecurity Research.
Introduction 3 weeks ago, I posted a rant about my frustration/concern related with crypto tools, more specifically the lack of tools to implement crypto-based protection for files on OSX, in a point-&-click user-friendly way.

Unfortunately I don’t have as much spare time as I used to, or would like to, so I often have no other choice than to redirect questions to our forums or our IRC channel (#corelan on freenode), hoping that other members […]The post How to become a pentester first appeared on Corelan Cybersecurity Research.
Introduction Hi all, While preparing for my Advanced exploit dev course at Derbycon, I’ve been playing with heap allocation primitives in IE. One of the things that causes some frustration (or, at least, tends to slow me down during the research) is the ability to quickly identify objects that may be useful. After all, I’m […]The post Analyzing heap objects with mona.py first appeared on Corelan Cybersecurity Research.
As the CSO/CISO/person responsible for Information Security, your job is to… well … do you even know? Does upper management know? "Our crappy CSO …" and "Our stupid CSO …" are statements commonly used by various (techie) people, throwing their hands up in despair, attempting to prove that their CSO doesn’t understand technology and has […]The post CSO : Common Sense Operator/Operations first appeared on Corelan Cybersecurity Research.
Last year, Belgacom got hacked by an intelligence service (GCHQ?), Rob says. “What is so interesting about this hack, why did they hack into Belgacom, what would or could be the purpose of a similar hack?” Before answering those questions, we need to take a quick look on how mobile networks work and how mobile […]The post HITB2014AMS – Day 2 – On Her Majesty’s Secret Service: GRX & A Spy Agency first appeared on Corelan Cybersecurity Research.
iOS Browsers & UIWebview iOS is very popular (according to StatCounter, it’s the 3rd most popular platform used). Mobile browsers take about 20% to 25% of the market share. iOS offers integration with desktop browsers and cloud (so the same data is available to an attacker). Many 3rd party IOS browsers have similar weaknesses which […]The post HITB2014AMS – Day 2 – Exploring and Exploiting iOS Web Browsers first appeared on Corelan Cybersecurity Research.
