Spyware “Landfall” Exploits Zero-Day Vulnerabilities in Samsung Galaxy Devices
A new and sophisticated spyware campaign known as “Landfall” has emerged, targeting owners of recent Samsung Galaxy phones using multiple previously unknown security flaws. Landfall is particularly noteworthy for its ability to compromise devices through seemingly innocuous image files, representing a new evolution in mobile exploitation tactics.
Campaign Overview and Target Scope
The Landfall campaign began in mid-2024 and continued through early 2025, focusing on Samsung Galaxy S22-S24 series devices, as well as Z Flip and Z Fold 4 models. The primary geographic targets appear to be users in North African nations. Early findings suggest that individuals of interest to government and commercial surveillance buyers were among the primary victims.
Technical Analysis of the Exploit Chain
The spyware utilized a chain of zero-day vulnerabilities within Samsung’s proprietary Android image processing library. The attack vector involved malicious Digital Negative (DNG) format image files, which were transmitted through WhatsApp and likely other messaging platforms. Upon reception, simply viewing or processing the image could trigger remote code execution by exploiting flaws in image parsing routines.
Once the payload was delivered, a secondary download of a ZIP file occurred silently, executing the malicious code and granting full control over the device to the attacker. The modular nature of the implant allowed for lateral movement, data exfiltration, real-time surveillance, and potential persistence mechanisms on the affected smartphones.
Indicators, Impact, and Response
Victims potentially faced unauthorized access to messages, call logs, camera feeds, and stored credentials, posing significant risks to privacy and personal safety. Security teams are urgently investigating the forensic traces left by image-based exploits and collaborating with Samsung and messaging app vendors to identify and patch the vulnerabilities.
Samsung has issued advisories and is coordinating firmware updates to remediate the zero-day vulnerabilities. Experts recommend that at-risk users update their devices promptly, avoid opening suspicious image attachments, and monitor device behavior for anomalies.
