Responder Attack
A “Responder Attack” is a type of cyber attack that happens when an attacker sends a bunch of requests to a target. The idea is to overwhelm the target with so many requests that it can’t keep up with them all, causing it to slow down or crash.
The name “Responder Attack” comes from the fact that the attacker uses a tool called “Responder” to flood the target with requests. Responder is a legitimate tool used by security professionals, but attackers can also use it for malicious purposes.
One common type of Responder Attack is called an “NTLM Hash Theft Attack.” In this type of attack, the attacker sends requests to a target computer that uses NTLM authentication. The requests are designed to trick the computer into sending back the user’s NTLM hash, which the attacker can then use to try to crack the password.
To protect against Responder Attacks, security professionals recommend disabling NTLM authentication and using other security measures like firewalls and intrusion detection systems.
