Which cyber attack involves a coordinated attack from a botnet of zombie computers?ICMP redirectaddress spoofingDDoSMITM

Step 1: Break Down the Problem

To identify the type of cyber attack among the options given, we need to understand the nature of each attack mentioned:

1. ICMP redirect
2. Address spoofing
3. DDoS (Distributed Denial of Service)
4. MITM (Man-In-The-Middle)

Step 2: Relevant Concepts

• ICMP Redirect: This attack involves manipulation of the Internet Control Message Protocol to reroute traffic but does not typically involve a botnet.
• Address Spoofing: This refers to sending packets with a false source address. While it can be related to botnets, it is not specifically a coordinated attack like DDoS.
• DDoS: This is a style of attack where multiple compromised computer systems are used to flood a target with traffic, overwhelming it and resulting in denial of service.
• MITM: This involves an attacker intercepting and potentially altering the communication between two parties. It does not specifically use a botnet.

Step 3: Analysis and Detail

The most relevant attack that directly involves a coordinated effort from multiple compromised systems (often referred to as "zombie computers") is the DDoS attack. This type of attack utilizes a large number of computers, typically part of a botnet, to send a flood of requests to a target, which can lead to resource exhaustion and service denial.

Step 4: Verify and Summarize

Upon reviewing the definitions of the attacks, the DDoS attack clearly stands out as the one involving coordinated attacks from a botnet of zombie computers.

Final Answer

The cyber attack that involves a coordinated attack from a botnet of zombie computers is DDoS (Distributed Denial of Service).
