"Battery Low" Panic. You are at an airport or cafe, and your phone is about to die. You see a free public USB port. It seems like a lifesaver. Stop. You might be plugging straight into a hacker's device.
A standard USB cable has distinct pins for Power and Data. – Normal Port: Connects only power pins. – Hacked Port: Connects data pins too. This allows the station to siphon data while charging your phone.
In seconds, they can access: – Your Photos & Contacts – Full Phone Backup – Inject Malware or Ransomware Often, your phone won't even ask for permission, especially if it's an older model or unlocked.
The simplest defense is a tiny adapter called a USB Data Blocker. – How it works: It physically removes the data pins from the connection, allowing only electricity to pass through. – Result: Safe charging anywhere.
Never trust a port you don't own. – Rule: Use your own power bank or the AC wall adapter (the brick), never the direct USB socket. – Tip: If you must use a public port, power your phone OFF first.
