Threat actors deployed LANDFALL spyware via malicious DNG image files sent through WhatsApp, requiring zero user interaction. This out-of-bounds write vulnerability in Samsung's image processing library allows remote code execution, data theft, and surveillance.

Federal agencies must remediate by December 1, 2025.
