Juice jacking is a type of cyberattack involving a public charging port. While these public chargers are indeed a big help when the battery of your mobile device is drained, such ports may also be designed to steal your data or to automatically install malware in your device.
Scammers install malware into a specially modified charging port.
When you plug your mobile phone or other device into this modified charging port, the malware is installed on your device. The malware allows the hackers to access sensitive data via your phone — including contact details, emails, messages, photos, private videos and sensitive financial credentials.
