iPhone users have been warned seriously about using shared chargers. According to Ryan Montgomery, a cybersecurity expert, a seemingly normal charger could cause serious damage to your computer or mobile phone. The reason lies in a device known as the ‘O.MG cable’which beneath its harmless appearance hides advanced hacking capabilities.
This cable, which went on the market in 2019 at an initial price of about 170 euros, has an internal implant that includes a web server, USB communications and Wi-Fi access. Thanks to these features, cybercriminals can use it to capture keystrokes, steal credentials, extract data, and even install malware. Montgomery showed in a video how, by connecting this cable to a new computer, gained full access to the device without having to connect a mobile to the other end. He simply pressed a button on his phone to initiate the remote attack.
The ‘O.MG cable’ was originally designed as a tool for Red Team teams, cybersecurity professionals who simulate attacks to detect vulnerabilities. Mike Grover, the researcher who developed the cable, explained that it is a device that “looks identical to normal cables”, but it contains a sophisticated implant. According to Grover, this cable can control devices from up to 90 meters away and if connected to a nearby Wi-Fi network, its range becomes unlimited.
This device has been called the “world’s most dangerous USB cable” due to its ability to act covertly. Besides, People cannot visually distinguish an ‘O.MG cable’ from a conventional charger.
In 2023, a new version called ‘Elite Series’ was launched, which expanded the capabilities of the ‘O.MG cable’. This model includes variants in different formats, such as USB-A, USB-C cables and USB adapters. Even devices designed to protect against attacks, such as USB data blockers, may be equipped with these malicious functions.
Among the new features, the ability to exfiltrate data directly stands out, which allows attackers to steal sensitive information without being detected. Although the creator of the cable has included security measures, such as limiting its geographic reach or disabling it outside a specific area, some cybercriminals have already begun to exploit it.
Recommendations to protect yourself
The FBI and the Federal Communications Commission (FCC) have issued alerts about the use of public chargers and unknown cables. Although juice jacking poses minimal risks, Experts highlight that the threat of the ‘O.MG cable’ is much more real and significant.
To protect yourself, Users should avoid using chargers or cables that do not belong to them.. It is recommended to purchase equipment from certified brands and be wary of found or borrowed devices.
