Связь ближнего радиуса действия (NFC) позволяет таким устройствам, как смартфоны, передавать данные с помощью других технологий с поддержкой NFC, сближая два устройства. Это облегчает обмен информацией и открывает уязвимости устройства. По этой причине отключайте NFC на устройствах Android, когда в очень общественных местах, где хакеры могут охотиться на уязвимости телефона.
Как используется NFC
When used for non-malicious purposes, NFC brings additional functionality to a phone. However, there are risks involved when using NFC. Researchers at a Pwn2Own contest in Amsterdam showed how NFC can be exploited to gain control over an Android-based smartphone. Researchers at a Black Hat security conference in Las Vegas demonstrated similar vulnerabilities using different techniques.
NFC uses are common. Many retailers have signs at the checkout that tell customers that payment can be made with their phones through Google Wallet. Smartphones with Android 2.3.3 or newer may be configured to send or receive data through this communications standard.
