That wraps up #Zer0Con2024 and @andreyknvl class on Exploiting the Linux Kernel: “I’m Seouled”. What a week. Thanks @POC_Crew and all the wonderful people that I have met. 🙏🏻🇰🇷🌸
#Zer0Con2024 First 0day dropped 🤣 @munmap, @patateQbool Guess what device it is
Great start to #Zer0Con2024 !
With so many high achieving people in security it’s common to feel like you never get enough work done. You should always take a step back and appreciate yourself. If you worked hard it will compound! Keep the momentum up! 💪
Way to go @chompie1337 !!! $15,000 feels like a scam for a Win11 LPE, especially because you had to circumvent VBS…

I'm so excited today to announce that I'm launching my own online training platform @CalypsoLabs 🎊 The first course to appear on Labs is "Windows Instrumentation with Frida", check it out: labs.calypso.pub/windows-instru… Labs is partnering with @vector35, when you sign up you get a…

Happy to share the first part in a two part blog series about KTIMER Hijacking, a post-exploitation technique to leave ticking time bombs in the kernel! Thanks @yarden_shafir for pointing out this research topic during your Windows Internals course. gerr.re/posts/ktimer-h…
That’s a wrap for #REcon2023! Thanks @yarden_shafir and Winsider (@aionescu) for the deep insights into Windows Internals, learned a ton 🤯
#flareon9 is over! Read my blogpost where I walk through my favourite challenge of this year: 09_encryptor gerr.re/posts/flareon9… #writeup
Done with #flareon9. Had a great time! Thanks @Mandiant and @nickharbour and the FLARE team for exposing me to various different topics. Liked the crypto, disliked the .NET 😂
Back home from an AWEsome #DEFCON30 and #BHUSA2022. Thanks @Blomster81 and @_sickn3ss_ from @offsectraining for the mind boggling days and sleepless nights (worth it taking the coin home). This heavy binder will be the stepping stone towards #OSEE and the uncensored samurai!
CVE-2022-27438 - Many products that are built using Advanced Installer 19.3 and prior are vulnerable to remote attackers allowing them to execute arbitrary code. Vendors, make sure to update to version 19.4 and use code signing! gerr.re/posts/cve-2022… @advinst
