How hackers are using phone chargers to steal your data. Tips to stay safe
Ryan Montgomery, an ethical hacker known for identifying security flaws in company networks, has recently warned the public about the risks of using charging cables from unknown sources. Montgomery shared his findings on Instagram, cautioning that charging cables that seem harmless could actually pose significant cybersecurity threats.
How Hackers Use Chargers to Access Your Data
In a demonstration, Montgomery plugged an ordinary-looking cable into a new computer. Despite appearing to be just a regular charging cable, it gave him full access to the device. With a few simple actions, Montgomery was able to control the computer remotely from his phone. “Never trust a cable that’s not yours,” he stated in the viral video, which has amassed over 400,000 views.
This phenomenon, known as "juice jacking," occurs when a corrupted USB charging port or cable is used to infect your device with malware. The malware can steal sensitive data, lock your device, or even give hackers complete control over your device. Public charging stations, such as those found in airports and shopping malls, are known hotspots for this type of attack. Montgomery’s advice? Avoid using USB charging stations whenever possible.
To protect against these threats, cybersecurity experts recommend using a USB data blocker. This small device acts as a shield, preventing data from being transferred while still allowing your device to charge. Montgomery advocates for using these blockers, especially when traveling or using public charging stations.
