Understanding Juice Jacking: How Attackers Exploit Public USB Charging Ports
Juice jacking is a cyberattack where criminals compromise public USB ports to steal data or install malware on connected devices. The moment you plug in, your device can begin transmitting personal data without any visible sign.
Researchers have documented fileless malware like JS_POWMET.DE arriving via USB flash disks, abusing legitimate system functions to install backdoors invisibly. According to Trend Micro’s USB malware research, these attacks leave almost no trace on infected systems.

Secure Charging Alternatives: Personal Power Banks and Wall Adapters for Travelers
Always carry a personal power bank — it eliminates any need to use public USB ports entirely. If you must use a public outlet, plug in your own wall adapter with your own cable, bypassing any data-transfer risk completely.
Before your next trip, review your passport’s bio-data page and ensure no sensitive travel documents are stored unencrypted on your phone. A USB data blocker is also an inexpensive, effective layer of protection worth packing.
