Notepad++ has addressed a critical security vulnerability in its update mechanism that was exploited by an advanced threat actor from China to deliver targeted malware. The issue involved hijacking the software’s update process to selectively infect specific users, highlighting a sophisticated attack vector that compromised the integrity of the update system.

In response, Notepad++ released version 8.9.2, which includes a ‘double lock’ design implemented by maintainer Don Ho to enhance security. This update aims to make the update process robust and effectively unexploitable by adding verification measures, thereby preventing similar exploits in the future and protecting users from such targeted attacks.
