Warning Issued to Android Users About Wireless Charging Vulnerabilities

In the fast-evolving digital age, the convenience offered by wireless charging for our devices comes with its own set of cybersecurity risks. Recent findings from cybersecurity experts highlight a newly discovered weakness in wireless chargers that could potentially allow hackers to damage your smartphone severely. This revelation stems from a study conducted by a group of researchers, which has sparked significant concern over the safety of using wireless charging technology.

Understanding the Risks

The study sheds light on specific vulnerabilities within wireless charging systems that can be exploited through electromagnetic interference. Dubbed ‘VoltSchemer’ by the researchers, this attack method capitalizes on weaknesses in the communication protocol between the smartphone and the charging unit. These vulnerabilities could enable malicious individuals to engage in a range of nefarious activities, from disrupting the charging process to causing physical damage to the device being charged.

The Mechanics of the Attack

The research team’s investigation into this issue revealed that VoltSchemer specifically targets two inherent aspects of standard wireless charging systems. Firstly, it exploits the open communication channel used to align the charging device with the receiver. Secondly, the lack of encryption in this process, designed to allow for wide compatibility across devices, presents a golden opportunity for hackers.

Through their experiments, the experts demonstrated how an attacker could masquerade a malicious device as a harmless power adapter or a wall USB socket. Once in proximity to a wireless charger, this rogue device can interfere with the normal charging process, leading to potentially dangerous outcomes.

Potential Consequences

The implications of such attacks can range from mild to severe. The researchers showcased a scenario where a manipulated charger caused a metal object, such as a paperclip, to reach extreme temperatures, in some cases enough to ignite flammable materials. While this example illustrates the potential for physical damage, it also underscores the critical nature of this security flaw.

Staying Safe

Despite these alarming findings, it’s essential to note that the risk primarily concerns public or untrusted wireless charging stations. Your personal charging devices at home are less likely to be targeted in such a manner. However, for those who frequently rely on public charging stations or shared wireless chargers, there are measures you can take to protect your devices. Carrying a personal, portable charger offers a safer alternative, allowing you to avoid the risks associated with public charging spots entirely.

As the digital landscape continues to evolve, staying informed about potential cybersecurity threats is crucial. This latest revelation regarding wireless charging systems serves as a reminder of the importance of vigilant device management and the need for ongoing research to identify and mitigate emerging vulnerabilities.


The convenience of wireless charging has become an integral part of modern mobile device usage, but it doesn’t come without its drawbacks. Awareness and caution are key when using public charging solutions to avoid falling victim to sophisticated cyber-attacks that exploit inherent vulnerabilities in these technologies. By staying informed and taking proactive steps to secure our devices, we can enjoy the benefits of wireless charging without compromising our digital security.
