Researchers detailed a “commercial‑grade” spyware campaign that exploited CVE-2025-21042, an out‑of‑bounds write in Samsung Galaxy devices, to deliver LANDFALL via specially crafted images sent over WhatsApp. The now‑patched flaw enabled remote code execution, allowing attackers to exfiltrate data, record calls, access photos and logs, and track locations in targeted Middle East operations. Organizations with Samsung fleets should fast‑track patching and review MDM policies for rapid OS and firmware updates.
