Application Vulnerability

Today I want to talk about a security threat known as “browser session hijacking.”

This is an attack where a hacker steals the information that identifies you on the internet. Once successful, the attacker has unchallenged access to your online banking, social media, and other online accounts — without ever needing your password. The scary part? You’d never know it was happening.

There is a recently identified security vulnerability in the Microsoft Notepad application included with Windows 11. Modern versions of Notepad allow formatted text features that support clickable links within documents. In certain situations, clicking one of these links could trigger harmful behavior, potentially leading to malicious software being downloaded or run.

This does not mean Notepad itself is dangerous — rather, attackers may try to exploit how links are handled when users open and interact with untrusted files.
