Exploit Development with AFL, PEDA and PwnTools
In this tutorial, we expand on our previous article on AFL by developping a simple exploit using PEDA and Pwntools.
The Solfa Cipher (NSEC17 Write-Up)
The Solfa Cipher Between May 19th and 21st, 2017, I’ve participated in the NSEC 17 Capture-the-Flag (CtF) event held annually in Montreal, QC. As usual, the team and I had a blast spending days and nights solving challenges and drinking free beer. Among the challenges was a two-part cryptographic puzzle printed on the first and last […]
Software Exploit Development – Fuzzing with AFL
It’s quite impressive to look back in the past to the early days of software vulnerabilities and observe the ongoing dance between new mitigation and new exploitation techniques. Powerful fuzzing tools are now commonplace and operated on a daily basis by IT corporations and security labs; either to find crashes in their software or others’ […]
Reversing the Trendnet TS-402
The Trendnet TS-S402 is a discontinued network storage enclosure that was sold to individuals for personal data storage. Like every Internet-of-Things (IoT) device, it runs on software programmed and/or configured by the manufacturer before shipping it to the end-user, i.e. the firmware. Firmware versions 2.00.10 and below of this particular device have a serious vulnerability allowing remote […]
The Past, Present and Future of Chinese Cyber Operations
China, as one of many alleged actors on the frontier of cyber espionage, is best understood by briefly examining the past century, how it influences contemporary cyber operations attributed to Chinese-based actors, and how they could be used against the Canadian Armed Forces in a potential Southeast Asian conflict.
Firefox Javascript Vulnerability
Once again, Javascript is the source of a new exploit that has been recently discovered on Firefox1. The vulnerability can be exploited by crafting malicious Javascript code on a Firefox 3.5 browser and leads to the execution of arbitrary code on the user’s machine. This is due to a vulnerability in the JIT engine of […]
A small and quick introduction to ARP poisoning
This article won’t be about something new nor something extraordinary for any experienced computer security or even the average hacker, but since I’ve been ask this question quite often by some of my friends, I decided to explain how to sniff passwords from a network. Moreover, I’m well aware I haven’t been writing anything for […]
