In today’s fast-paced world, where smartphones are as essential as our wallets, it’s not uncommon to find ourselves with a dying battery and a friend offering their charger. However, a stark warning from cybersecurity experts suggests that sharing iPhone chargers could be a grave mistake, potentially leading to dire consequences for your digital security.
Ryan Montgomery, a seasoned cybersecurity professional, has raised the alarm about the dangers lurking within seemingly innocuous iPhone chargers. At the heart of this warning is a device known as the ‘O.MG cable,’ which, while appearing to be a standard charging cable, harbours a sinister secret. This cable is equipped with a hidden implant that includes a web server, USB communications, and Wi-Fi access, turning it into a tool for cybercriminals to capture keystrokes, steal credentials, exfiltrate data, and deploy malware.
The deceptive nature of the O.MG cable is what makes it particularly dangerous. It was made available to the public in 2019 for a relatively modest sum of $180, considering its capabilities. Montgomery demonstrated the cable’s power in a video, showing that without even connecting an iPhone, he could gain full access to a computer by simply plugging in the cable and pressing a button on his phone.
The cable’s creator, security researcher Mike Grover, has designed it to be indistinguishable from ordinary cables. However, each one contains an implant that allows for remote access and control. Grover has stated that the cable could enable him to access a device from up to 300 feet away, and potentially from an unlimited distance if configured to connect to a nearby wireless network.
The implications of such technology are alarming. It is virtually impossible for an average person to discern whether they are using one of these compromised cables, and there is almost no way to detect an active attack. As a result, the O.MG cable has earned the title of the world’s ‘most dangerous USB cable.’
The capabilities of the O.MG cable are evolving, becoming more sophisticated over time. The ‘Elite series,’ launched in 2023, includes various form factors such as USB-A, USB-C cables, adapters, and even data blockers, which are typically used to protect against data theft. This latest series has introduced the ability to steal data, adding to the cable’s stealthy specifications.
While the O.MG cable was designed for professional hackers like Montgomery, who test data systems for vulnerabilities, there is a real concern that malicious actors have obtained these cables. The FBI has reported that bad actors have found ways to use public USB ports to install malware and monitoring software on devices. The Federal Communications Commission (FCC) has also warned about ‘juice jacking,’ where USB charging stations are weaponised to steal data.
To mitigate the risks, Grover has implemented safety features in the cables, such as restricting the access range to a specific location and designing them to not sync and charge when armed. However, the threat remains significant, and experts strongly advise against using any charger that you did not purchase yourself.
