A special episode this week, featuring an interview with John Carse, Chief Information Security Officer (CISO) of SquareX. John speaks about his background in the security industry, grants insight into attacks on browsers, and talks about the work his team at SquareX is doing to detect and mitigate browser-based attacks.
A long episode this week, featuring an attack that can leak secrets from Gemini's Python sandbox, banks abusing private iOS APIs, and Windows new Hypervisor-enforced Paging Translation (HVPT).
API hacking and bypassing Ubuntu's user namespace restrictions feature in this week's episode, as well as a bug in CimFS for Windows and revisiting the infamous NSO group WebP bug.
This episode features some game exploitation in Neverwinter Nights, weaknesses in mobile implementation for PassKeys, and a bug that allows disclosure of the email addresses of YouTube creators. We also cover some research on weaknesses in Azure.
Discussion this week starts with the ESP32 "backdoor" drama that circled the media, with some XML-based vulnerabilities in the mix. Finally, we cap off with a post on reviving modprobe_path for Linux exploitation, and some discussion around an attack chain against China that was attributed to the NSA.
In many ways, mobile devices lead the security industry when it comes to defense-in-depth and mitigation. Over the years, it has been proven time and again that the kernel cannot be trusted to be secure. As such, there has been effort put into moving secrets (ie. encryption keys) and other sensitive data out of the kernel and gate it behind an API at higher levels in the chain of trust, whether it be the hypervisor or secure enclaves. In any case, the kernel must have a lot of control over the s
This week's episode features a variety of vulnerabilities, including a warning on mixing up public and private keys in OpenID Connect deployments, as well as path confusion with an nginx+apache setup.
We discuss an 0day that was dropped on Parallels after 7 months of no fix from the vendor, as well as ZDI's troubles with responses to researchers and reproducing bugs. Also included are a bunch of filesystem issues, and an insanely technical linux kernel exploit chain.
We cover a comical saga of vulnerabilities and variants from incomplete fixes in macOS, as well as a bypass of Chrome's miraclePtr mitigation against Use-After-Frees (UAFs). We also discuss an attack that abuses COM hijacking to elevate to SYSTEM through AVG Antivirus, and a permissions issue that allows unauthorized access to DRM'd audiobooks.
In this episode, we discuss the US government discloses how many 0ds were reported to vendors in a first-ever report. We also cover PortSwigger's top 10 web hacking techniques of 2024, as well as a deep dive on how kernel mode shadow stacks are implemented on Windows by Connor McGarr.
On the web side, we cover a portswigger post on ways of abusing unicode mishandling to bypass firewalls and a doyensec guide to OAuth vulnerabilities. We also get into a Windows exploit for a use-after-free in the telephony service that bypasses Control Flow Guard, and a data race due to non-atomic writes in the macOS kernel.
Zero Day Initiative posts their trends and observations from their threat hunting highlights of 2024, macOS has a sysctl bug, and a technique leverages CloudFlare to deanonymize users on messaging apps. PortSwigger also publishes a post on the Cookie Sandwich technique, and Subaru's weak admin panel security allows tracking and controlling other people's vehicles.
This week features a mix of topics, from polyglot PDF/JSON to android kernel vulnerabilities. Project Zero also publishes a post about excavating an exploit strategy from crash logs of an In-The-Wild campaign.
