The EDR blind spot: 3 ways browser attacks evade endpoint telemetry

BleepingComputer
Actively Exploited

Overview

Browser-based attacks pose a significant risk as they can steal sessions, misuse browser extensions, or manipulate users without triggering the alerts that endpoint detection and response (EDR) systems are designed to catch. This means that traditional security measures may overlook these types of threats, leaving users vulnerable. NordLayer outlines three methods that attackers use to bypass endpoint telemetry, emphasizing the importance of implementing browser-level controls to enhance security. This is particularly crucial for companies that rely heavily on web applications, as the lack of visibility into browser activity can lead to data breaches and compromised user accounts. Organizations need to be aware of these tactics to better protect their systems and users.

Key Takeaways

  • Active Exploitation: This vulnerability is being actively exploited by attackers. Immediate action is recommended.
  • Affected Systems: Browser-based sessions, web applications, browser extensions
  • Action Required: Implement browser-level security controls and monitor user activity within web applications.
  • Timeline: Newly disclosed

You gave your AI agent access, but who is giving it orders?

BleepingComputer

AI agents, designed to assist users, can be manipulated by attackers to perform harmful actions such as stealing data or deleting files. This exploitation occurs through common methods like malicious emails, websites, and plugins that trick the AI into executing unauthorized commands. Gen Digital has introduced its Agent Trust Hub, which aims to enhance the security of these AI agents by verifying their skills, ensuring secure connections, and implementing runtime controls to stop harmful actions before they can cause damage. This incident raises concerns about the security of AI tools, as they operate with legitimate permissions that can be abused if not properly safeguarded. Users and companies need to be vigilant about the commands they give to AI agents and the potential risks involved.

Critical Flaw in Python’s Popular Pillow Image Library Allows Code Execution via a Crafted Image

The Hacker News

A serious vulnerability has been discovered in Pillow, the most popular image processing library for Python, allowing attackers to execute arbitrary operating system commands on servers. The flaw, identified as CVE-2026-112900, arises from how Pillow processes EPS (Encapsulated PostScript) images. When Pillow opens these images, it passes the file name to Ghostscript without proper validation, which can be exploited by malicious users. This issue could potentially impact any application or server that uses Pillow to handle EPS images, making it a significant risk for developers and companies relying on this library for image processing. Users are urged to take immediate action to protect their systems from potential exploitation.

Researchers Demonstrate Node2Shell RCE Exploit on Node.js Build Using Crafted Brotli Data

The Hacker News

Researchers from Imperva have discovered a vulnerability in Node.js that allows attackers to execute arbitrary code through malicious Brotli data. This exploit, known as 'Node2Shell', was tested successfully on the official Node.js version 24.22.0 for Linux arm64 without any custom modifications. The flaw, identified as CVE-2026-111497, arises from the way the Brotli decoder processes crafted input. This means that applications using this official build could be at risk if they process untrusted Brotli data. It's crucial for developers and companies using Node.js to be aware of this vulnerability to safeguard their applications and users.
