Wrote some microbenchmarks to reverse engineer some undocumented aspects of cache coherence and cache design on AMD CDNA 3 GPUs github.com/MrRoy09/AMD-CD…

Wrote a blog post on the #AMD CDNA #GPU memory model and how synchronization between thousands of threads is made possible in a scalable manner by the LLVM compiler. read it here - 21verses.xyz/2026/01/13/CDN…

Our FPGA based accelerator for CKKS-based CNN convolutions for secure inference was selected as one of the winning projects in the AMD Open Hardware Competition! With @sp0oky_daksh openhw.eu/2025_results_1 github.com/MrRoy09/AOHW_3…

Wrote a short blog post on Subgraph Isomorphism - A problem that shows up everywhere from program analysis to computer vision. The question is simple: how do you find if a smaller pattern is embedded within a larger network? 21verses.blog/2025/10/29/sub…

blog.thalium.re/posts/llvm-pow… An attempt to use taint analysis to deobfuscate virtualized binaries by lifting to LLVM IR and performing dynamic slicing analysis

zimperium.com/blog/saturn-so… Interesting read on leveraging LLVM for removing software obfuscations. Consistent with my experiments that LLVM cannot remove virtualized functions automatically but it deals well with Opaque predicates.

@sanyakapoorrr Thanks a ton !

@21verses saw you on the discord congrats 🎉

Had a great time working on the tool! Excited to continue working on it. Big thanks to the organizers for hosting the event and sparking this idea

Published the first part of my blog series on Homomorphic Encryption and the CKKS scheme. We'll gradually dive deeper into the mathematics in future posts. Hope you enjoy this introduction! 21verses.blog/2025/09/26/int…

arxiv.org/pdf/2211.13546 Great resource for studying the NTT algorithm, commonly used for Post Quantum lattice based cryptography to speed up polynomial multiplication

Obfuscated using Virtualization Transform of tigress 3.1

So much fun working on an LLVM based taint engine to attack Virtualization obfuscation. Lot of challenges atm, but results seem promising. Great resource btw -> blog.thalium.re/posts/misc/llv… Obfuscated -> Deobfuscated

@expend20 @krishna_2803 @PTRACE_TRACEME @cystariitm Sure. I would recommend testing the passes. It’s something we plan to work on as well when time permits. The competition only required a POC, so more thorough testing is due.

@21verses @krishna_2803 @PTRACE_TRACEME @cystariitm hi! great stuff, are you okay if I incorporate some/all of your passes into shifting.codes?

Had a great time designing an obfuscation engine with @krishna_2803 and @PTRACE_TRACEME for BinaryClash360 by @cystariitm. Found out about a lot of cool stuff - obscure compiler flags, LLVM tricks. Ended up winning second place in the competition too github.com/MrRoy09/VMwhere

A simple blog post about Recursive disassembly and Program control flow graphs. 21verses.blog/2025/04/30/Rec…

@peter_clowncs Finally , Congratulations!!

I wrote a blog post exploring the math behind #dataflow analysis. Frequently used in #compilers, #decompilers, static analyzers, etc. Hope you enjoy it! 21verses.blog/2025/02/09/Int…

Received this cute little thing
