Table 3 Summary of different attacks in IoT system [36]
Attack Name | Description |
|---|---|
DoS attack | Illegitimate users prevent legitimate users from accessing any device or service by flooding that device or service with false incoming requests. |
Sniffer attack | Packet or sensitive information is captured by hackers using an application during the transmission stage in network, if it isn’t adequately encrypted. |
IP spoofing | Source IP addresses are added to data packet headers to hijack a network-connected user’s browser. |
Malware attack | A piece of software that performs malicious activities on the machines of users without their knowledge. Spyware and ransomware are two examples. |
Wormhole attack | Malicious nodes in an IoT network build a tunnel, deceiving other nodes into thinking the two malicious nodes are close to each other and thus attracting data packets. This causes routing issues, and malicious nodes can tamper with data packets. |
Sinkhole attack | During data transmission, a malicious node attacks a neighbouring nodes in order to reduce their efficiency. |
Black hole attack | The malicious node receives data packets from neighbouring nodes but discards them. |
Man-in-middle attack | Unknown person or malicious intrudes between the sender and receiver’s conversation and attempts to access confidential information. |
