Microsoft has alerted users that FIDO2 security keys may require a PIN for sign-in following recent Windows updates since September 2025. This change could affect user experience and security practices, particularly for those relying on these security keys for authentication.

The article discusses the risks associated with outdated operational technology (OT) security systems, drawing a parallel to the 1980s nostalgia of 'Stranger Things.' It emphasizes that reliance on legacy technology can expose organizations to significant cybersecurity threats, highlighting the need for modernization in security practices. The core issue is the potential vulnerabilities that arise when organizations fail to update their OT security measures.

ASUS has issued a firmware update to address nine security vulnerabilities, including a critical authentication bypass flaw in routers with AiCloud functionality. This flaw poses a significant risk as it could allow unauthorized access to the routers, potentially compromising user data and network security.

The article highlights the risks associated with using community-maintained tools like Chocolatey and Winget for system updates. While these tools offer convenience for IT teams, their open nature allows anyone to modify packages, potentially exposing systems to vulnerabilities. This duality presents a significant challenge for maintaining security while leveraging community resources.

The Festo Compact Vision System and related products have critical vulnerabilities that could allow unauthorized access and modification of configuration files, with a CVSS score of up to 9.8. Users are urged to implement security measures to mitigate the risk of exploitation, as these vulnerabilities could severely impact device security and integrity.

The article discusses a vulnerability in Opto 22's groov View that allows for the exposure of sensitive information through metadata, potentially leading to credential and key exposure as well as privilege escalation. This vulnerability, assigned CVE-2025-13084, has a CVSS v4 score of 6.1 and affects multiple versions of groov View, necessitating immediate remediation to mitigate risks.

CISA has released seven advisories addressing security vulnerabilities in various Industrial Control Systems (ICS). These advisories highlight the need for users and administrators to review the technical details and implement mitigations to protect against potential exploits.

The Ashlar-Vellum products Cobalt, Xenon, Argon, Lithium, and Cobalt Share have critical vulnerabilities, specifically an Out-of-Bounds Write and a Heap-based Buffer Overflow, which could allow attackers to disclose information or execute arbitrary code. The vulnerabilities have a CVSS v4 score of 8.4, indicating a high severity level, and users are urged to update their software to mitigate risks.

The SiRcom SMART Alert (SiSA) system has a critical vulnerability due to missing authentication for critical functions, allowing unauthorized remote access to backend APIs. This could enable attackers to manipulate emergency sirens, posing a significant risk to public safety and critical infrastructure.

The Zenitel TCIV-3+ device has critical vulnerabilities, including OS Command Injection and Cross-site Scripting, with a CVSS v4 score of 10.0, indicating a severe risk of arbitrary code execution and denial-of-service. Users are strongly advised to upgrade to version 9.3.3.0 or later to mitigate these risks.

Rockwell Automation's Arena Simulation software has a stack-based buffer overflow vulnerability that could allow local attackers to execute arbitrary code. The vulnerability, identified as CVE-2025-11918, has a CVSS v4 score of 7.1, indicating a significant risk for affected installations, particularly in critical manufacturing sectors.
