Over the past several years, CISA, the Cybersecurity and Infrastructure Security Agency, has released a steady stream of guidance encouraging software manufacturers to adopt Secure by Design principles, reducing customer risk by prioritizing security throughout the product development process. This is particularly critical for the operational technology (OT) sector, where vulnerabilities in industrial control systems…

Software development has always presented long-established programming languages with opportunities and challenges, including C++, which has long been a mainstay. However, C++ has come under scrutiny due to memory safety concerns. Because of its robust security features, developers often use Rust as an alternative language.

OpenPaX, a New Linux Memory Security Patch, Arrives – The New Stack
-
OpenPaX is an open-source kernel patch that mitigates common memory safety errors, re-hardening systems against application-level memory safety attacks using a simple Linux kernel patch. It’s available under the same GPLv2 license terms as the Linux kernel.

Mounting memory? This changes everything! TL;DR Memory forensics is crucial for investigations, providing access to volatile data, like running processes and network connections. MemProcFS is a game-changer tool in memory forensics, allowing memory dumps to be mounted and browsed like file systems, simplifying the analysis of complex memory structures. Tools like Volatility (versions 2 and…

TL;DR Memory forensics enhances investigations by analysing volatile data (in RAM) unavailable in disk forensics. Key insights from memory include running processes, network connections, encryption keys, and user activity, vital for real-time investigations. Smaller memory images (4-32 GB) offer faster analysis compared to large disk images (250+ GB). Critical artifacts like malware, passwords, encryption keys,…

As malware detection techniques evolve, so do the methods attackers use to evade them. VOIDMAW is an innovative memory scanning bypass technique that can effectively hide problematic code from antivirus software. It supports multithreaded payloads and is compatible with all Command-and-Control (C2) beacons. Additionally, VOIDMAW can run any non-.NET executables, making it a powerful tool…

TL;DR Direct Memory Access (DMA) attacks are a powerful class of attack that give read and write access to the memory of a target system, bypassing the main CPU to gain kernel privileges. We became interested in DMA attacks for expanding the toolkit for rooting embedded devices. A lot of embedded systems run Linux, and…
