This week we get to take a look into some basic heap grooming techniques as we examine multiple heap overflows. We also briefly discuss the hand-on (by the DoD and Synack) assessment of the "unhackable" morpheus chip, and briefly discuss the new-ish paper claiming to defeat RSA.
This week we talk a bit about newly released Black Hat 2020 and NDSS 2021 presentation videos, before jumping into several pre-auth RCEs, and some interesting exploitation research to bring a PAC enforced Shadow Stack to ARM and an examination of JSON parser interoperability issues.
A couple privacy violations, PDF exploits, and a complicated API being misused by developers.
"Beg Bounty" hunters, dependency confusion, iOS kernel vuln, and how not to respond to security research.
A lot of discussion this week about OSS security and security processes, an iOS kernel type confusion and MediaTek Bootloader bypass impacting everything since atleast 2014.
Starting with a long discussion about the North Korean hackers targeting security reseachers, and some thoughts (rants) about the newly released Windows exploit dev course from Offensive Security before getting into some real exploits including NAT Slipstreaming 2.0 and a new Sudo vuln.
tl;dr The rest of this goes into detail about what topics matter and why from each resource, but if you want to cut to the chase and ignore that... * Prerequisites * C programming language * x86 Assembly (32bit and 64bit) * Linux terminal usage * Exploit Education - Nebula - Start thinking like an attacker and learning to do research * Open Security Training - Introduction to Software Exploitation - Fundamentals of memory corruption * Pwn College - (Added July 2022) An alt
This week is a shorter episode, but still some solid bugs to look at. From a full chain Chrome exploit, to a Kindle chain from remote to root and a eBPF incorrect calculation leading to OOB read/write.
Several lockscreen-related vulnerabilities this week, a cross-site leak, and the hijacking of all .cd domains.
A new universal deserialization gadget for Ruby, a Rocket.Chat SAML auth bypass, and some heap exploitation research.
