Cybersecurity researchers have discovered a bypass for a now-patched security vulnerability in the NVIDIA Container Toolkit that could be exploited to break out of a container's isolation protections and gain complete access to the underlying host. The new vulnerability is being tracked as CVE-2025-23359 (CVSS score: 8.3). It affects the following versions - NVIDIA Container Toolkit (All versions up to and including 1.17.3) - Fixed in version 1.17.4 NVIDIA GPU Operator (All versions up to and including 24.9.1) - Fixed in version 24.9.2 "NVIDIA Container Toolkit for Linux contains a Time-of-Check Time-of-Use ( TOCTOU ) vulnerability when used with default configuration, where a crafted container image could gain access to the host file system," the company said in an advisory on Tuesday. "A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering." Cl...

CISOs are finding themselves more involved in AI teams, often leading the cross-functional effort and AI strategy. But there aren’t many resources to guide them on what their role should look like or what they should bring to these meetings.  We’ve pulled together a framework for security leaders to help push AI teams and committees further in their AI adoption—providing them with the necessary visibility and guardrails to succeed. Meet the CLEAR framework. If security teams want to play a pivotal role in their organization’s AI journey, they should adopt the five steps of CLEAR to show immediate value to AI committees and leadership: C – Create an AI asset inventory L – Learn what users are doing E – Enforce your AI policy A – Apply AI use cases R – Reuse existing frameworks If you’re looking for a solution to help take advantage of GenAI securely, check out Harmonic Security .  Alright, let’s break down the CLEAR framework.  Create an AI Asset Invent...

The North Korea-linked threat actor known as Kimsuky has been observed using a new tactic that involves deceiving targets into running PowerShell as an administrator and then instructing them to paste and run malicious code provided by them. "To execute this tactic, the threat actor masquerades as a South Korean government official and over time builds rapport with a target before sending a spear-phishing email with an [sic] PDF attachment," the Microsoft Threat Intelligence team said in a series of posts shared on X. To read the purported PDF document, victims are persuaded to click a URL containing a list of steps to register their Windows system. The registration link urges them to launch PowerShell as an administrator and copy/paste the displayed code snippet into the terminal, and execute it. Should the victim follow through, the malicious code downloads and installs a browser-based remote desktop tool, along with a certificate file with a hardcoded PIN from a rem...

Microsoft on Tuesday released fixes for 63 security flaws impacting its software products, including two vulnerabilities that it said has come under active exploitation in the wild. Of the 63 vulnerabilities, three are rated Critical, 57 are rated Important, one is rated Moderate, and two are rated Low in severity. This is aside from the 23 flaws Microsoft addressed in its Chromium-based Edge browser since the release of last month's Patch Tuesday update . The update is notable for fixing two actively exploited flaws - CVE-2025-21391 (CVSS score: 7.1) - Windows Storage Elevation of Privilege Vulnerability  CVE-2025-21418 (CVSS score: 7.8) - Windows Ancillary Function Driver for WinSock Elevation of Privilege Vulnerability "An attacker would only be able to delete targeted files on a system," Microsoft said in an alert for CVE-2025-21391. "This vulnerability does not allow disclosure of any confidential information, but could allow an attacker to delete d...

Ivanti has released security updates to address multiple security flaws impacting Connect Secure (ICS), Policy Secure (IPS), and Cloud Services Application (CSA) that could be exploited to achieve arbitrary code execution. The list of vulnerabilities is below - CVE-2024-38657 (CVSS score: 9.1) - External control of a file name in Ivanti Connect Secure before version 22.7R2.4 and Ivanti Policy Secure before version 22.7R1.3 allows a remote authenticated attacker with admin privileges to write arbitrary files CVE-2025-22467 (CVSS score: 9.9) - A stack-based buffer overflow in Ivanti Connect Secure before version 22.7R2.6 allows a remote authenticated attacker to achieve remote code execution CVE-2024-10644 (CVSS score: 9.1) - Code injection in Ivanti Connect Secure before version 22.7R2.4 and Ivanti Policy Secure before version 22.7R1.3 allows a remote authenticated attacker with admin privileges to achieve remote code execution CVE-2024-47908 (CVSS score: 9.1) - Operating sy...

Google has stepped in to clarify that a newly introduced Android System SafetyCore app does not perform any client-side scanning of content. "Android provides many on-device protections that safeguard users against threats like malware, messaging spam and abuse protections, and phone scam protections, while preserving user privacy and keeping users in control of their data," a spokesperson for the company told The Hacker News when reached for comment. "SafetyCore is a new Google system service for Android 9+ devices that provides the on-device infrastructure for securely and privately performing classification to help users detect unwanted content. Users are in control over SafetyCore and SafetyCore only classifies specific content when an app requests it through an optionally enabled feature." SafetyCore (package name "com.google.android.safetycore") was first introduced by Google in October 2024, as part of a set of security measures designed to...

Multi-factor authentication (MFA) has quickly become the standard for securing business accounts. Once a niche security measure, adoption is on the rise across industries. But while it’s undeniably effective at keeping bad actors out, the implementation of MFA solutions can be a tangled mess of competing designs and ideas. For businesses and employees, the reality is that MFA sometimes feels like too much of a good thing. Here are a few reasons why MFA isn’t implemented more universally. 1. Businesses see MFA as a cost center MFA for businesses isn’t free, and the costs of MFA can add up over time. Third-party MFA solutions come with subscription costs, typically charged per user. Even built-in options like Microsoft 365’s MFA features can cost extra depending on your Microsoft Entra license. Plus, there’s the cost of training employees to use MFA and the time IT takes to enroll them. If MFA increases help desk calls, support costs go up too. While these expenses are far less t...
