Breaking News:Unveiling the Silent Threat: Android Devices Harboring Unkillable Backdoors

In the ever-evolving landscape of technology, Android devices have become an integral part of our lives, from smartphones to smart TVs. However, a hidden menace threatening our digital security and privacy lies beneath the surface of convenience. Recent discoveries have brought to light a concerning issue – unkillable backdoors embedded within Android devices, including TVs and smartphones. 

The Silent Invaders

Security researcher Daniel Milisic stumbled upon a startling revelation when he encountered a seemingly innocuous Android TV streaming box known as the T95, which was infected with malware right out of the box. Other vigilant researchers corroborated his findings, and together, they unveiled a disturbing reality. Android devices, particularly the T95 and its ilk, come with an uninvited guest – malware. These devices are not just limited to our homes; they have infiltrated businesses and educational institutions.

The Intricate Web of Fraud

Further investigations conducted by Human Security have exposed the extent of the infection. Seven Android TV boxes and one tablet were found to harbour these backdoors, along with 200 other Android devices scattered across the globe. The infected devices have created a complex web of fraudulent activities, presenting a multifaceted challenge for cybersecurity experts.

The Swiss Army Knife of Fraud

The Chief Information Security Officer (CISO) at Human Security, Gavin Reid, aptly describes these compromised devices as “a Swiss Army knife of doing bad things on the Internet.” This metaphor underscores the versatility of these backdoors in facilitating a wide array of fraudulent activities. They serve as the perfect tool for executing distributed fraud schemes.

The Elusive Culprit

The origin of these infected devices lies in China, though the precise point at which the firmware backdoor is introduced remains mysterious. Unbeknownst to users, upon connecting these devices, they establish a connection to a command and control (C2) server in China. From there, they download an instruction set and commence their nefarious operations, often without the owner’s knowledge.

The Widespread Implications

According to international news online, the ramifications of these compromised devices are profound. They have been implicated in various types of fraud, including advertising fraud, the provision of residential proxy services, the creation of fake Gmail and WhatsApp accounts, and even remote code installation. The scale of this threat is substantial, with potentially millions of devices affected worldwide.

 A Global Supply Chain Challenge

One of the most concerning aspects of this threat is its supply chain infiltration. The backdoors are surreptitiously introduced at some point in manufacturing, making them exceedingly difficult to detect. Manufacturers face a monumental challenge in safeguarding their products from such insidious tampering.

The App-Based Fraud Element

In addition to the compromised devices, Human Security’s research also uncovered an app-based fraud element known as “Peachpit.” This operation involved 39 Android, iOS, and TV box apps, often of low quality and covering innocuous topics like fitness and hydration tracking. These apps concealed hidden advertisements and engaged in web traffic spoofing and malvertising.

A Staggering Impact

The scale of the ad fraud operation associated with Peachpit is staggering. The fraudulent ads were responsible for a mind-boggling 4 billion ad requests daily. Approximately 121,000 Android devices and 159,000 iOS devices fell victim to this scheme. In total, the Android apps involved in this operation garnered 15 million downloads, underscoring the far-reaching consequences of this cyber threat.

 The Battle Against the Silent Threat

Breaking News: Both Google and Apple have taken action in response to Human Security’s research findings. Google removed the 20 Android apps associated with the fraudulent operation from the Play Store, while Apple identified and addressed issues in five reported apps. However, the threat still lingers in countless households, with malware that is notoriously difficult to eradicate.


In summary, unkillable backdoors in Android devices severely threaten our digital lives. These “Badboxes” are akin to sleeper cells, lying in wait for malicious instructions. The battle against this silent threat is ongoing, highlighting the ever-evolving nature of cybersecurity challenges. As technology advances, so must our vigilance and preparedness in the face of such hidden dangers.
