My research blog about #JSCeal is finally out! It was quite a journey. I hope you will like it! // #V8 #bytecode #malware #deobfuscation
#JSCeal didn't give up its secrets willingly. Following our #BlackHat2026 talk, we're releasing Breaking the Seal: our research on statically deobfuscating compiled, obfuscated #V8 #malware. Inside: the methodology, the open-source toolkit, and the malware capabilities recovered
@ant4g0nist Do you know his Twitter handle? Want to follow him!
@ant4g0nist Yeah, this guy is a fantastic presenter. The most important thing this is his real experience. Bravo!
We are already passing Vendor Test Suite (VTS) and other test suites for sensors, hard drive, UFS, etc!
Not sure if someone noticed, the animation is inverted. The bug is fixed! The challenge we took for this phone is to virtualize it without actual phone. Want to see how further we can push without the actual phone! At some point we might need the actual phone as many specs are NDA guarded!
Now this supports secure call, syscall tracing and booting from PBL->XBL chain. More SOCs support coming soon.
OnePlus 12 - Qemu This SoC supports ~40 phone models from different vendors
We are building AI agents to FIND and FIX bugs on scale using ONLY open source models. If you are into AI and have experience with BUGS, ping us!!
My #BHUSA 2026 slides are online! It was an honor to share our AFD research and how a different perspective led to 30+ Windows kernel vulnerabilities. Blog post coming soon — check out the slides here: i.blackhat.com/BH-USA-26/Pres…
Slides from my today's talk at #BlackHatUSA2026 : "Breaking the Seal: Static Deobfuscation of Compiled #V8 JavaScript Bytecode #Malware" : speakerdeck.com/hshrzd/breakin… // #BHUSA #BlackHat2026
@FAMASoon I'm glad HEVD was useful to you!
syzlang deserves better than plaintext. syzlang-vscode: syntax highlighting + language server for syzkaller descriptions. Go-to-def, find refs, hover, autocomplete, diagnostics. MIT. github.com/hacksysteam/sy… #syzkaller #fuzzing
@whokilleddb But, the RWX is not due to CoW but the tool didn't update the permissions after hooking.
Here are the slides for my Scudo talk yesterday for the MobileHackingLab Con: github.com/3sjay/talks/bl… it has two extra slides I haven't addressed in my talk. One describing two common misconceptions and one showing the shuffle count for each class.
Started a blog series on writing a minimal ARM hypervisor from scratch — boots as a UEFI app, claims EL2, identity-maps everything through Stage 2. Chapter 0 just dropped: ARM vs x86 virtualization, UEFI internals, EDK2 setup, first app at EL2. 0xabe.io/hypervisor/arm…
The slide is available now: github.com/ThomasKing2014… . Thanks for the fantastic conference @POC_Crew. Happy New year.
Slides from @st424204 & @Peterpan980927 's talk at @codeblue_jp is now live! “AI Accelerated Exploiting: Compromising MTE-Enabled Pixel from DSP Coprocessor.” Slides: github.com/star-sg/Presen…
While y’all discounting your mediocre courses, @zerodaytraining is doubling down on my pro offers: - Foundations + Hypervisor = Escape Bundle (new) - Foundations + Browser = Remote Bundle (new) - Foundations + Hypervisor + Browser = Elite Bundle (new) That’s a full roadmap from zero to zero day engineer.
Winter Bundles are here ✨🎄✨ Bundles are one of our most requested features. Today, we've put together our best self-paced trainings to keep one's head cool on Christmas and well into 2026. Limited availability through mid January Details: zerodayengineering.com/winter-deals.h…
