Many people use public charging stations to recharge their smartphones during travel or daily outings. However, few realize the risks of connecting their devices to publicly available USB ports. Security experts refer to this technique as "juice jacking." It involves transferring malicious software to a device via a USB cable, which charges the device and allows data transfer.
The history of such attacks includes cases like Mactans, identified in 2013 by the Georgia Institute of Technology, and USB Ninja, which looks like a standard cable but can install malicious software. Another example is KeySweeper – which appears to be an ordinary charger but logs wireless keyboard activity and transmits data via GSM to the attacker.
How to protect yourself
In light of the growing threat, officials from Los Angeles and various technology portals recommend avoiding connecting devices to public chargers. The safest solution is to use your own charger connected directly to a power outlet or to use power banks.
An innovative solution is the so-called USB Condom (SyncStop) – a special cover for the cable that blocks data transfer, allowing only charging.
Public chargers can be compared to keeping a wallet in the back pocket – nothing might happen, but there is a risk that someone could take advantage of it. In times when smartphones store our personal data, photos, and passwords, it is wise to be particularly cautious to avoid falling victim to scammers.
Regularly securing devices, avoiding suspicious cables, and choosing safe charging methods can protect our information from potential leakage or theft.
