Microsoft has resolved a known issue that caused Always On VPN connection issues after installing the September 2026 Windows 11 security updates. The Always On VPN remote access solution replaced the legacy DirectAccess technology and works with domain-joined, non-domain-joined, and Microsoft Entra ID–joined Windows 10, Windows 11, and Windows Server devices. Always On VPN runs in the background and automatically establishes a secure tunnel back to the corporate network whenever a device connects to the internet. As Microsoft first acknowledged in a service alert sent to IT administrators in late September, the bug triggered Always On VPN failures if the initial connection fails (e.g., when using automatic protocol selection with IKEv2 and SSTP) on up-to-date systems running Windows 11 24H2 and later.
AI-powered penetration testing can uncover complex attack paths, but safety restrictions and network limitations leave many assets and vulnerabilities untested. Picus Security explains how combining agentic pentesting with exposure validation and breach simulation can help close these gaps.
A massive cybercriminal ecosystem facilitating more than a billion malicious messages targeting over 75,000 organizations across 150 countries has been disrupted by law enforcement agencies and partners worldwide. Since the start of the year, more than 750 million malicious messages have been aimed at Microsoft customers via email and SMS texts. Following an investigation initiated by Microsoft and Japan’s National Police Agency (NPA) into a wave of fraudulent activity, "a sprawling Chinese-language cybercrime marketplace" was discovered, with tools and services for phishing campaigns. The investigators traced the malicious activity to YAM Store (Storm-3119), an underground infrastructure marketplace, then linked it to the CoGUI, Haozi, and Iron Man System phishing kits, collectively tracked as Storm-2990.
A new Android malware called Hirudo steals bank account credentials by replacing legitimate banking apps with modified versions that disable security checks.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday urged organizations to take steps to immediately update their Ivanti Connect Secure (ICS) appliances and deployments to the latest version following the disclosure of an actively exploited vulnerability. The security flaw, tracked as CVE-2026-104935 (CVSS score: 8.6), is a case of authentication bypass impacting ICS
Cybersecurity researchers have disclosed details of a new Android banking trojan called Hirudo that works by replacing legitimate banking apps with purpose-built patched versions designed to bypass security checks from inside the app itself, marking a new escalation in financial fraud. Dutch mobile security company ThreatFabric said it identified replacements for eight Indonesian banking
The bug was simple: the login let you choose where your sign-in code went. Proving it on a live website was the hard part. TL;DR During an authorized assessment, an AI pentesting agent found a critical authentication bypass on a major insurer's production website, on its own. One login request let the user choose where the one-time passcode went. The attack was the easy part. Proving it

A critical heap buffer overflow vulnerability (CVE-2026-39919) in the Ghostscript interpreter and rendering engine could allow remote code execution through specially crafted PDF files. The flaw was discovered on August 23 by researchers at Defiant's platform Wordfence using their Argus AI-powered system. Ghostscript is a PostScript and PDF interpreter that can render PDFs as images, generate thumbnails for previews, and optimize PDF files by compressing embedded images and removing unnecessary font data. When generating a PDF thumbnail, WordPress can use the PHP Imagick extension to call ImageMagick, which launches Ghostscript. A specially crafted PDF file containing a JPEG 2000 image can trigger incorrect handling of low-bit-depth samples and mismatched component resolutions. Using Argus, the researchers developed two exploits for CVE-2026-39919 that force Ghostscript to write 1,024 bytes into a 256-byte buffer, corrupting nearby memory and leading to unauthenticated remote code execution in a WordPress deployment.
Small artificial intelligence (AI) models may be months away from developing capabilities to self-replicate on IoT devices like smart ovens and off-brand Android TV boxes, according to a warning from Anthropic. The frontier AI lab said small AI models could form autonomous, self-propagating worm botnets that are "challenging to shut down," since "there's no centralized point to shut off."
