If you are a user of the X social media platform, then beware these ‘near-perfect’ fake login notification warnings: they are a scam, and your password is at risk.

Google has rolled out another Chrome update, version 151.0.7922.71/.72, across all platforms except iOS, addressing 370 security vulnerabilities. Among these fixes are four specifically identified as "use-after-free" memory issues. These critical vulnerabilities involve a program accessing memory after it has been freed, potentially leading to system crashes, data corruption, or the execution of malicious code. Crucially, none of the patched vulnerabilities are known to have been exploited in the wild. Experts emphasize that Google's frequent updates and transparent disclosure of such flaws are a positive indicator of proactive security measures.

Google asserts that increased vulnerability discovery and fixing, especially with AI, signifies stronger security, not failure. This comes amidst concerns about AI's dual role in cybersecurity, following incidents like OpenAI's Hugging Face. Google's Chrome security team details how AI models are deployed at scale for discovery, triage, and remediation of flaws. AI-powered tools like LLMs, fuzzing, and Gemini find vulnerabilities, automate validation, and generate fixes, saving significant developer time. Google ensures its AI operates in secure, isolated environments. This approach dramatically accelerates security updates, with Chrome now piloting twice-weekly releases, ultimately making the browser and the broader web safer by minimizing the patch gap.

Everyone knows that passwords need to be strong and unique, and they should be kept secret.

Wouldn't it be great if the world's most popular web browser, Google Chrome, with an estimated 3.5 billion users, just updated itself automatically when new security issues were found and fixed?

Microsoft has paid a record amount to a record number of researchers for identifying and disclosing security vulnerabilities between June 2025 and July 2026.

Google Chrome can now install security updates automatically on macOS when no browser windows are open, though the feature is more limited than it first appears.

The August 2026 Android update has dropped, and Google has published the accompanying announcement that stated: “This Android Security Bulletin

Ransomware incidents are on the rise, with attackers increasingly using AI, despite attention on AI-powered breaches. However, Microsoft's Defender is showcasing a new autonomous protection feature, claiming it can halt ransomware attacks in just 128 seconds. A recent case study involving QNET demonstrated this capability, where Defender successfully isolated a compromised endpoint. This swift action prevented a second-stage payload from establishing persistence or stealing credentials, effectively breaking the attack chain and lateral movement. While device isolation offers critical containment by blocking external network access, security experts emphasize that foundational cybersecurity controls, including multi-factor authentication and privileged access management, remain indispensable for comprehensive protection.

Microsoft says a new Defender capability isolated a compromised device and stopped a ransomware attack in 128 seconds. Security experts explain what it means—and its limits.
