A danger to be aware of is public USB charging stations. These are often welcome sights especially if you’re low on battery power. However, hackers can infect public USB charging ports with malware and set up fake charging stations in public areas. Then, when you insert your USB cord to charge your device, the malware is copying all the data on your phone and/or infecting it with malicious code. See, USB cables aren’t just for charging, they are also used for data transmission.
It’s best to avoid public USB charging ports and charge with your power adapter that plugs into an outlet instead. You can also buy a “charge-only” USB cord to use if USB charging is your only option.
