Digital photo frames are supposed to be simple, feel-good devices — plug them in, load your favourite pictures, and let the slideshow run. But for a growing number of users, some Android-powered models are doing far more behind the scenes than displaying memories. Recent research shows that several Uhale-based photo frames are quietly downloading malware every time they boot up.
A Troubling Discovery Behind a Simple Gadget
Mobile security firm Quokka recently performed a deep investigation into the Uhale app, which powers many Android digital picture frames sold under different brand names. Their findings weren't just concerning — they were alarming.
According to their report, the app's behaviour strongly resembles known malware families, including Mezmess and Voi1d, suggesting these devices may be part of a much larger, coordinated ecosystem of malicious activity.
What makes the situation worse is that the researchers attempted to alert ZEASN (now rebranded as Whale TV), the company behind the Uhale platform. Despite multiple notifications dating back to May, no response ever came.
Malware Delivered Automatically at Every Boot
The most serious issue revolves around how these devices update themselves. Instead of checking for safe, digitally verified updates, many Uhale-powered frames:
This means users never see any warning or prompt — the entire infection process happens silently each time the frame powers up.
Quokka's analysis found these devices were rooted out of the box, shipped with SELinux disabled, and used AOSP test-keys, all of which leave them extremely vulnerable. In short, these frames are shipped in a wide-open state, making malware execution trivial.
The downloaded payloads were linked to the Vo1d botnet and Mzmess malware, based on naming patterns, endpoint behaviour, and file structures.
The worrying part? Researchers still don't know how the initial infection starts.
Multiple Layers of Security Failures
The malware problem is only part of the story. Quokka uncovered 17 separate security vulnerabilities, 11 of which have been assigned CVE identifiers. Together, these issues create a device ecosystem that is trivially exploitable.
Some of the most critical issues include:
1. Remote Code Execution via Forged TLS Responses
An insecure TrustManager lets attackers spoof encrypted traffic, effectively giving them the power to run commands as root.
2. Command Injection During App Updates
The update system passes filenames directly into shell commands without validation, allowing attackers to install any APK they want.
3. Devices Are Already Compromised at Purchase
With SELinux disabled, default rooting, and public test-keys, the devices are insecure from the moment they are unboxed.
4. Open File Server Exposed to the Network
A file server running on TCP port 17802 accepts uploads or deletions from anyone on the local network, no authentication required.
5. WebViews That Completely Ignore Security
WebViews accept mixed content and ignore SSL errors, opening the door to phishing, spoofing, and injected malicious content.
On top of all that, the researchers found:
A Hidden Problem Across Many Brands
One of the biggest challenges is identifying who is affected. Uhale's software is used in digital photo frames sold under various names, often without mentioning the underlying platform.
Because of this:
This means the number of impacted users could be far larger than initially assumed.
Attempts by BleepingComputer to contact ZEASN for clarification also went unanswered.
What Consumers Should Do
Security experts recommend avoiding low-cost electronics from unknown or unverified brands, especially when they run modified Android firmware without proper protections.
When choosing smart home devices, especially those running Android, users should look for products that include:
In the world of IoT, a harmless-looking photo frame can become an unexpected entry point for malware — and this incident is a sharp reminder to buy carefully.
