Happy to be in the SCAN CTF final again. I hope the final will have some really difficult, AI-resistant challenges. Another shredder challenge would be fun too :)))

テックブログ事後学習編公開！ 概要編、前処理編、事前学習編に続き、音声言語モデルのTTSへの事後学習に関する知見をまとめています。 blog.dubguild.com/melte/post… ・SFT＋RLによってJ-HARDのCERと話者類似度を改善 ・報酬設計次第では発話が不自然に長くなり、声質がほぼ女性側へ偏る ・BF16では、vLLMとTransformers間のトークン対数確率の差がFP16の約8倍に拡大

I participated in ICC 2025. ICC is a CTF where teams compete by continent, with both Jeopardy-style and Attack & Defense CTFs. I wanted to share a fun story from the A&D, where I tried exploit other teams internal tools. Thanks to the organizers and players @icctokyo2025

Last week, I enjoyed COMPFEST and got two first bloods. First time using Huff "2", and the new builtins made building contracts easier. Also played JailCTF, not blockchain but really one of my favorites CTFs

pushed the challs for hitcon, 07ctf, and cbc github.com/minaminao/my-ctf-… tried making a rev one on EVM that could easily be solved using a symbolic execution engine like hevm, but it ended up with 0 solves😭 hevm is now highly compatible with Foundry, the experience was quite good

Long time no post — I've been casually running a CTF platform for individual players called @AlpacaHack for the past year. This weekend, we're hosting a new 6-hour Crypto round. Feel free to give it a try! alpacahack.com/ctfs/round-13

Do you know that calling the function in the following EOF contract results in a revert? This is definitely a potential pitfall ... 🙃

I created a challenge at SECCON CTF that explored EVM Object Format (EOF)🧩 It revealed two emerging pitfalls: Contract Recreation Failures and Call Return Mishandling. It was tough—only 2 teams solved. Give it a try to deepen your understanding of EOF: github.com/minaminao/my-ctf-…
