A rogue DHCP server is a DHCP server on a network which is not under the administrative control of the network staff. It is a network device such as a modem or a router connected to the network by a user who may be either unaware of the consequences of their actions or may be knowingly using it for network attacks such as man in the middle.
DHCP servers allocate IP addresses to clients on a LAN. DHCP snooping can be configured on LAN switches to exclude rogue DHCP servers and remove malicious or malformed DHCP traffic. In addition, information on hosts which have successfully completed a DHCP transaction is accrued in a database of bindings which may then be used by other security ...
The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client–server architecture.
The adversary can then set up a rogue DHCP server so that clients receive incorrect network settings and as a result transmit data to an attacker's machine. [8] One method for mitigating this type of attack is to use the IP source guard feature available on many Ethernet switches. The IP guard initially blocks all traffic except DHCP packets.
A "soft access point" (soft AP) can be set up on a Wi-Fi adapter using for example Windows' virtual Wi-Fi or Intel's My WiFi. This makes it possible, without the need of a physical Wi-Fi router, to share the wired network access of one computer with wireless clients connected to that soft AP.
MAC address authentication in combination with discretionary DHCP server settings allow a user to set up an "allowed MAC address" list. Under this type of security, the access point will only give an IP Address to computers whose MAC address is on the list. Thus, the network administrator would obtain the valid MAC addresses from each of the ...
Customer information and device operation would be available to the potential attackers, including other MAC addresses on client's networks. Covert redirection of DNS queries to a rogue DNS server might be possible, and even surreptitious firmware updates with backdoor features. [6]
DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. [1] This can be achieved by malware that overrides a computer's TCP/IP configuration to point at a rogue DNS server under the control of an attacker, or through modifying the behaviour of a trusted DNS server so that it does not comply with internet standards.
