Hackers Spied on Samsung Phones with Booby-Trapped Images – No Click Needed
Table of Contents
A sophisticated hacking campaign targeted select Samsung Galaxy users for months, exploiting a previously unknown vulnerability to install spyware without requiring any action from the victims. Security researchers at Palo Alto Networks Unit 42 recently revealed details of the operation, dubbed “Landfall,” a commercial-grade spyware capable of extensive device monitoring.
How the Attack Worked
The attack vector centered around maliciously crafted images. These images, when viewed on vulnerable Samsung devices, exploited a zero-day vulnerability in the image processing component. This allowed hackers to install the “Landfall” spyware silently,bypassing typical security measures and without prompting the user to grant permissions. The exploit worked without the need for users to click on links or download suspicious files.
Details of the ‘Landfall’ Spyware
“Landfall” is described as a highly capable spyware package. Researchers found it capable of exfiltrating a wide range of data, including call logs, SMS messages, contacts, and location data.It could also intercept credentials stored on the device. Palo Alto Networks Unit 42 has published a detailed technical analysis of the spyware’s capabilities and infrastructure.
Affected Devices and Timeline
The researchers did not disclose the exact number of devices affected, but confirmed the campaign targeted a specific subset of Samsung Galaxy users. The vulnerability exploited is reportedly a zero-day, meaning it was previously unknown to Samsung and security vendors. the campaign was active for several months before being discovered and analyzed. Palo Alto Networks Unit 42 worked with Samsung to address the vulnerability.
Samsung’s Response
Samsung has released a security patch to address the vulnerability exploited by the “Landfall” spyware. Users are strongly advised to update their devices to the latest software version as soon as possible. The patch is available through Samsung’s standard software update channels.

While this specific vulnerability has been patched, experts recommend practicing good mobile security habits. These include keeping your device’s software up to date, being cautious about the images you view, and only downloading apps from trusted sources. Consider using a reputable mobile security app for added protection.
The “Landfall” campaign highlights the growing sophistication of mobile espionage. Zero-day exploits are particularly hazardous because they offer attackers a window of opportunity before defenses can be implemented. The increasing reliance on mobile devices for sensitive data makes them prime targets for hackers and nation-state actors. This incident underscores the importance of proactive security measures and rapid vulnerability patching.
