Answer B is correct; the teardrop attack is a DoS that works by sending overlapping fragments that, when received by a vulnerable host, can cause a system to crash. Incorrect Answers and Explanations: B, C, and D. Answers B, C, and D are incorrect. In a Smurf attack, the attacker floods an ICMP ping to a directed broadcast address, but spoofs the return IP address, which traditionally might be the IP address of a local Web server. This is done by expensing all resources, so that they cannot be used by others. A Smurf attack is a resource consumption attack using ICMP Echo as the mechanism. Syn Flood Direct Attack. All rights reserved Cookie Policy Privacy and Legal Modern Slavery Statement. Smurf attack. J. Rosenberg, in Rugged Embedded Systems, 2017. A Smurf attack is a distributed denial-of-service (DDoS) attack in which an attacker attempts to flood a targeted server with Internet Control Message Protocol (ICMP) packets. A utility known as Ping sends ICMP Echo Request messages to a target machine to check if the target machine is reachable. The server has to spend resources waiting for half-opened connections, which can consume enough resources to make the system unresponsive to legitimate traffic. Each host sends an ICMP response to the spoofed source address. With Smurf attacks, perpetrators take advantage of this function to amplify their attack traffic. ICMP (Ping) Flood. If the attacker sends thousands of SYN messages the receiver has to queue up the messages in a connection table and wait the required time before clearing them and releasing any associated memory. A SYN flood attacker sends just the SYN messages without replying to the receiver's response. 4) in the source address field of the IP packet. This creates a strong wave of traffic that can cripple the victim. Smurf is a DoS attacking method. Smurf attack. By continuing you agree to the use of cookies. Forrester Wave™: DDoS Mitigation Solutions, Q4 2017, A Guide to Protecting Cryptocurrency from Web Threats and DDoS Attacks, DDoS Attacks Grow More Sophisticated as Imperva Mitigates Largest Attack, Imperva SD-SOC: How Using AI and Time Series Traffic Improves DDoS Mitigation, The Threat of DDoS Attacks Creates A Recipe for Election Chaos, Lessons learned building supervised machine learning into DDoS Protection, SQL (Structured query language) Injection, See the similarities between smurf attacks & ping floods, See the steps involved in a smurf attack scenario. On a multi-access network, many systems may possibly reply. Attacks on the ICMP protocol, including smurf attacks, ICMP floods, and ping floods take advantage of this by inundating the server with ICMP requests without waiting for the response. The Smurf attack is a distributed denial-of-service attack in which large numbers of Internet Control Message Protocol (ICMP) packets with the intended victim's spoofed source IP are broadcast to a computer network using an IP broadcast address.Most devices on a network will, by default, respond to this by sending a reply to the source IP address. Another type of ICMP-based attack is a smurf attack. On your Cisco routers, for each interface, apply the following configuration: This will prevent broadcast packets from being converted. The attackers are able to break into hundreds or thousands of computers or machines and install their own tools to abuse them. In this type of attacks attacker used to consumes the actual resources of server and this is measured in packet per second. ICMP Echo attacks seek to flood the target with ping traffic and use up all available bandwidth. Session hijacking involves a combination of sniffing and spoofing to allow the attacker to masquerade as one or both ends of an established connection. ICMP Flood, Ping Flood, Smurf Attack An ICMP request requires the server to process the request and respond, so it takes CPU resources.
