A mathematics event like no other, and even better, it's taking place DownUnder 20-24th July! Students, early, mid, and senior career researchers are all welcome!

What can the histories of mathematics from all societies worldwide tell us about mathematics we may need to tackle 21st century global problems? Your contribution will be welcomed and valued. Register before 5th June to secure your place, as numbers are limited due to venue constraints, at

https://maths.anu.edu.au/news-events/events/global-mathematics-histories-and-futures

This workshop is a first for Australian mathematics, and aligns with similar international initiatives, with an exciting program of Keynote and Guest Lectures, moderated roundtable discussion/ brainstorming sessions, contributed talks and posters. We aim to bring together cross-cultural, historical, and frontier mathematical knowledge.

The organisers thank the generosity of our sponsors #ANU-MSI #AustMS #AMSI #SMRI .

Эволюция загрузки вредоносных файлов или как хакеры перешли из файловой системы в оперативную память

Стандартная обфускация больше не спасает от систем защиты. Сегодня битва за скрытность идет на уровне системных вызовов и манипуляций с библиотеками в реальном времени. В этой статье мы проследим динамику развития обходов: от классического патчинга AMSI до современных методов уклонения от EDR.

r-tec Blog | Bypass AMSI in 2025

This blog post will shed some light on what's behind AMSI (roughly, but hopefully easy to understand) and how you can still effectively bypass it - more than four years later.

AMSI Bypass via RPC Hijack (NdrClientCall3) This technique exploits the COM-level mechanics AMSI uses when delegating scan requests to antivirus (AV) providers through RPC. By hooking into the NdrClientCall3 function—used internally by the RPC runtime to marshal and dispatch function calls—we intercept AMSI scan requests before they're serialized and sent to the AV engine. #amsi #windows #cybersecurity

AMSI Write Raid Bypass Vulnerability | OffSec

In this blog post, we'll introduce a new bypass technique designed to bypass AMSI without the VirtualProtect API and without changing memory protection.

I just discovered an interesting #AMSI bypass which uses a massive amount of overlapping Unicode characters. Apparently if you append a few hundred before and after a known malicious command (such as an AMSI bypass, or "Invoke-Mimikatz"), AMSI either crashes or ignores the #PowerShell code in between the odd code blobs.

The best part is that the code doesn't even need to be obfuscated! Tested this on Windows 10/11 and Server installs with success.

#AMSI Winter School at QUT, #Brisbane has finished! What an excellent 2 weeks that was. I learned about #fisheries #modelling, model sloppiness, and reinforcement learning, and I got to share evolutionary game theory with a bunch of enthusiastic students.
