Up until now, as people experiment with Agentic AI and tool support, they’ve mostly adopted the MCP stdio transport, which means you end up with a 1:1 deployment of MCP server and MCP client.

By layering practical, tactical deception into your environment, you shift the balance of power: slowing them down, forcing mistakes, and gaining early warning long before real damage is done.

Steganography can be defined like this: It is the art and science of concealing a secret message, file, or image within an ordinary-looking carrier - such as a digital photograph, audio clip, or text - so that the very existence of the hidden data is undetectable to casual observers. --------------------------------------------- https://isc.sans.edu/diary/rss/31892 ∗∗∗ Zoom attack tricks victims into allowing remote access to install malware and steal money ∗∗∗ --------------------------------------------- Attackers are luring victims into a Zoom call and then taking over their PC to install malware, infiltrate their accounts, and steal their assets. --------------------------------------------- https://www.malwarebytes.com/blog/news/2025/04/zoom-attack-tricks-victims-i… ∗∗∗ GitHub potential leaking of private emails and Hacker One ∗∗∗ --------------------------------------------- A bit over a month ago, I was crawling GitHub’s API while working on code input (—it is still in beta). I was compiling a list of repositories and pull requests to identify those with merge conflicts. At some point, while randomly checking some user profiles, I noticed email addresses appearing in the API that weren’t visible on the public profiles. --------------------------------------------- https://omarabid.com/hacker-one ∗∗∗ How I Got Hacked: A Warning about Malicious PoCs ∗∗∗ --------------------------------------------- This is a reminder that even experienced security researchers and exploit developers can fall victim to well-disguised malware. Always verify PoCs manually, isolate them in a controlled environment, and never underestimate how creative attackers can be when hiding malicious payloads. --------------------------------------------- https://chocapikk.com/posts/2025/s1nk/ ∗∗∗ Step-by-Step Guide: SOC Automation — SMB Threat Hunting & Incident Response Lab ∗∗∗ --------------------------------------------- In this project, I will simulate a similar attack scenario in which an insider compromises a Windows server by delivering malware through the SMB protocol. By leveraging automation and the incident response lifecycle, the goal is to detect and contain the threat before it spreads, demonstrating best practices in threat detection and response. --------------------------------------------- https://detect.fyi/step-by-step-guide-soc-automation-smb-threat-hunting-inc… ===================== = Vulnerabilities = ===================== ∗∗∗ Sicherheitsupdates: Nvidia-Grafikkartentreiber unter Linux und Windows löchrig ∗∗∗ --------------------------------------------- Besitzer einer Nvidia-Grafikkarte sollten zeitnah den GPU-Treiber aus Sicherheitsgründen auf den aktuellen Stand bringen. Geschieht das nicht, können Angreifer unter Linux an mehreren Schwachstellen ansetzen und Computer attackieren. Außerdem gibt es noch abgesicherte Versionen von Cloud Gaming und vGPU-Software unter Windows. --------------------------------------------- https://www.heise.de/news/Sicherheitsupdates-Nvidia-Grafikkartentreiber-unt… ∗∗∗ Connectwise Screenconnect: Hochriskante Codeschmuggel-Lücke ∗∗∗ --------------------------------------------- Die Remote-Desktop-Software Screenconnect von Connectwise enthält eine Sicherheitslücke, die Angreifern das Einschleusen und Ausführen von Schadcode ermöglicht.

It has 3.5 million downloads, which also doesn’t include non CurseForge hosted downloads such as for Feed the Beast modpacks. Through the presented vulnerability, any public or semi public multiplayer server that includes Integrated Scripting is vulnerable to remote code execution by a player who is able to craft a few relatively simple items. --------------------------------------------- https://redvice.org/assets/pdfs/minecraft2025.pdf ∗∗∗ Critical SAP NetWeaver Vulnerability (CVE-2025-31324) Fixed: Actively Exploited in the Wild ∗∗∗ --------------------------------------------- SAP has recently released a critical security patch for a severe vulnerability in SAP NetWeaver Visual Composer that has been actively exploited in the wild.
