Chinese APT Exploits Ivanti CVE-2025-22457 with Malware

A newly disclosed vulnerability in Ivanti Connect Secure (ICS) VPN appliances has been weaponized in the wild by a Chinese nation-state threat actor, UNC5221. Tracked as CVE-2025-22457, this critical stack-based buffer overflow vulnerability allows unauthenticated remote attackers to execute arbitrary code, posing a significant risk to enterprise networks.

How RemOps Improves Security Without Slowing Down Engineering Teams

You’ve heard it a hundred times – security is everyone’s responsibility. But when security starts slowing things down, it’s usually engineering teams that feel the pain. Nobody wants to be the one responsible for shipping vulnerabilities into production, but at the same time, nobody wants security to be the reason releases grind to a halt. This is the dilemma DevSecOps was supposed to solve – bringing security into the development process without breaking everything.

Risk-Based Vulnerability Management in IT: Reducing Exploitability Through Automated Prioritization

Organizations face a monumental challenge managing cyber risk and vulnerabilities across expanding digital environments. Research indicates that security teams can remediate merely 10% of detected vulnerabilities due to resource limitations, emphasizing the urgent need for optimized prioritization methods. Risk-based vulnerability management (RBVM) addresses this challenge by focusing remediation efforts on vulnerabilities posing genuine risk to specific organizational assets and infrastructure.

Emerging Threat: Ivanti CVE-2025-22457

CVE-2025-22457, a critical vulnerability (CVSS 9.0) affecting Ivanti Connect Secure, Ivanti Policy Secure, and Ivanti ZTA Gateways. The issue stems from a stack-based buffer overflow triggered by sending a specially crafted X-Forwarded-For HTTP header. Successful exploitation enables unauthenticated remote code execution. This vulnerability was originally misidentified as a buffer overflow vulnerability that could not lead to either remote code execution (RCE) or denial of service (DoS).

Can You Really Pair Program with AI? (Aider & Cohere)

A new wave of AI development tools is changing how we write code, but can AI truly replace a human coding partner? In this video, we explore the capabilities of Aider and Cohere, two tools built to support real-time, conversational pair programming. We’ll break down how they work, where they shine, and the surprising limitations that came up during testing. Whether you're an experienced developer or simply curious about the future of coding, this deep dive will give you a clear picture of where AI-assisted programming stands today.

Adversary Tradecraft: Apache Tomcat RCE

CVE-2025-24813 is a critical vulnerability (CVSS base score of 9.8) affecting Apache Tomcat, a widely used open-source web server and servlet container. This issue affects Apache Tomcat: In this blog, we’ll simulate an attack and look at the activity within Graylog. Throughout the analysis, and at the conclusion of the post, we’ll provide practical threat-hunting and detection strategies you can implement in your own environments.
