The USB-C port is indispensable for smartphones.

It is a versatile port that can do both charging and data transfer,

 

Its versatility, on the flip side, also becomes an entry point for danger.

 

The Israeli company Cellebrite, which we covered in a previous article, provides tools for extracting smartphone data to investigative agencies.

The legitimate purpose is counter-terrorism and investigative cooperation, but if someone who knows the system abuses it, the USB-C port can easily become a channel for information leakage.

There is a real risk of "juice jacking" where simply plugging a cable into public charging ports at airports or cafes can lead to data being stolen behind the scenes while charging.

This is where it becomes important,

 

The idea is to control USB-C as "charge-only."

 

If data transfer is not possible, information cannot be stolen.

AntiSpyPhone is very powerful in this regard.

In the initial state, when LOCK is engaged, USB-C operates as charge-only.

In other words, unless you unlock the screen, no matter how much you access the port, data communication is completely impossible.

Even if the user is not aware, it is designed in hardware to be safe as "charging only."

However, when you want to charge at places like airports or cafes, you may have unlocked the LOCK to operate the screen.

If you plug in a USB-C cable in that state, normally data communication would also become possible.

This is where AntiSpyPhone's detailed settings come in handy.

Please select Charging-only from Settings → Security & Privacy → Exploit Protection → USB-C port.

If you enable this setting, the USB-C port will become charging-only even when the LOCK is unlocked, and data communication will be completely blocked.

In other words, you can ensure the peace of mind of "charging only" even at public charging spots.

Unfortunately, at this time, there is no software setting to switch the iPhone's USB-C port, which is said to have higher security than Android, to "charging-only."

iOS has a "USB Accessories" control feature that blocks data communication from the Lightning/USB-C port while the screen is locked to prevent unauthorized access, but it is only designed to "disable data communication when locked" and cannot be fixed to a completely charging-only mode.

 

With AntiSpyPhone, if you combine it with Qi charging, you can live your daily life without using the USB port.

 

Wireless charging reduces physical contact points, making it safer and more comfortable.

 

The best way to enhance security is to "reduce entry points."

If there is no door, there can be no intrusion.

Even advanced extraction tools like Cellebrite cannot be effective if USB-C is fixed to charging-only.

Will you underestimate the risks hidden in convenience, or prioritize safety with just one setting?

The answer is clear.

By making USB-C charging-only, your smartphone becomes a significantly stronger shield.

AntiSpyPhone comes standard with this mechanism and also offers users the flexibility to finely control it themselves.

Here is an environment where you can safely charge your smartphone, whether at the airport or in a cafe.
