CAPEC-604: Wi-Fi Jamming
CAPEC版本: 3.9
更新日期: 2023-01-24
攻击模式描述
In this attack scenario, the attacker actively transmits on the Wi-Fi channel to prevent users from transmitting or receiving data from the targeted Wi-Fi network. There are several known techniques to perform this attack – for example: the attacker may flood the Wi-Fi access point (e.g. the retransmission device) with deauthentication frames. Another method is to transmit high levels of noise on the RF band used by the Wi-Fi network.
前提条件
- Lack of anti-jam features in 802.11
- Lack of authentication on deauthentication/disassociation packets on 802.11-based networks
所需技能
后果影响
影响范围: Availability
技术影响: Other
说明: A successful attack will deny the availability of the Wi-fi network to authorized users.
影响范围: Availability
技术影响: Resource Consumption
说明: The attacker's goal is to prevent users from accessing the wireless network. Denying connectivity to the wireless network prevents the user from being able to transmit or receive any data, which also prevents VOIP calls, however this attack poses no threat to data confidentiality.
缓解措施
Countermeasures have been proposed for both disassociation flooding and RF jamming, however these countermeasures are not standardized and would need to be supported on both the retransmission device and the handset in order to be effective. Commercial products are not currently available that support jamming countermeasures for Wi-Fi.
