Wireless Attacks

• Cellular

• Bluetooth

• Near Field Communication (NFC)

• Radio Frequency ID (RFID)

• Wireless LAN

• Heatmaps

Cellular Networks

• Operated by telecom providers and are most widespread wireless networks

• Faster 5G cell Service has allowed service providers to offer fixed wireless service for internet connectivity

• Telecom service providers own, maintain and manage their own network equipment and facilities

• End users are not responsible for configuring or securing these cell networks

Bluetooth Attacks

• Bluetooth - wireless tech that uses short-range radio frequency (RF) transmissions for communications over short distances

• Primary type of Bluetooth network topology is a piconet

• Bluejacking - sends unsolicited messages to Bluetooth-enabled devices - more annoying than harmful

• Bluesnarfing - access unauthorized info from a wireless device through Bluetooth connection -copies emails, contacts, pics, or other data without owner's knowledge

Near Field Communication (NFC) Attacks

• A set of standards used to establish communication between devices in close proximity

• Devices using NFC can be active or passive

• Passive NFC can be read but does not read or receive info

• Active NFC can read info as well as transmit data

Radio Frequency Identification (RFID) Attacks

• Commonly used to transmit info between employee ID badges, inventory tags, book labels, and other paper-based tags that can be detected by a proximity reader

• Passive, do not require power supply (can be very small)

• susceptible to attacks such as unauthorized tag access, fake tags, and RFID cloning
