Hackers are known for their clever and innovative tactics, from using artificial intelligence to write emails that seem eerily personal, to using Google Maps to scare people. But now, a cybersecurity expert has revealed that they can even use seemingly harmless iPhone chargers to steal your personal data.
Ryan Montgomery, who specializes in testing digital security flaws in company networks, is warning people to be cautious when using charging cables that they haven't purchased themselves. In a recent Instagram post, he shared that these "ordinary-looking" chargers can actually cause major issues for your computer or phone.
This type of scam, known as "juice jacking," involves hackers loading malware onto charging cables. So, when you innocently plug your phone into your laptop or computer to charge, the malware infects your device and gives hackers access to your data. They can then steal your information by capturing your keystrokes, accessing your passwords, and even locking up your device completely.
To demonstrate this, Ryan filmed himself plugging a charger into a brand new computer that was not connected to a phone. He explained, "This is a fully functional cable, you can still charge a phone with it. With this cable plugged in, I have full access to this computer." With just the press of a button on his phone, he was able to gain "full access" to the device and even hacked it to display a pop-up message reading, "Protect your devices."
The questionable device in question is called an "OMG cable," which is described by its maker, Hak5, as "a hand made USB cable with an advanced implant hidden inside." This $179.99 wire is not intended for use by tech-savvy scammers, but rather for cybersecurity teams to practice defending against real hacks, also known as "Red Teams." As Hak5 explains, "These cables will allow you to test new detection opportunities for your defense teams. They are also extremely impactful tools for teaching and training."
To stay safe, security experts advise against using USB cables found already plugged into charging stations, if possible. USB charging ports are now found in a variety of places, from hotels and airports to trains and buses, giving scammers more opportunities to strike. Some experts even caution against using chargers given away by promoters, as it is easy and inexpensive for hackers to brand the wires with their own malware.
For Apple iPhone users, who are especially vulnerable to these attacks, it is recommended to carry your own charging cable, only charge from a trusted electrical outlet, and use portable batteries purchased from reputable retailers. "Never trust a cable that's not yours," Ryan emphasized. "And if you're really concerned, get a data blocker." A USB data blocker, also known as a USB "condom," acts as a barrier between cables and computers to prevent malware from sneaking in. It's better to be safe than sorry when it comes to protecting your personal data from these clever and cunning hackers.
