Before we start, I need to stress that this video is for informational purposes only. If you know how these attacks work, then you can better defend against them. Do not try this on any system that you do not own or have permission to do so.
ARP, or Address Resolution Protocol, is used to discover MAC addresses and map them to an associated IP address.
The way this works is very simple. A host broadcasts a message to the entire network asking for the correct MAC address.
Computers are very trusting of the ARP messages they receive, and this can cause problems. If an evil attacker sends a specially crafted ARP message (gratuitous ARP) the attack can pretend to be someone they are not.
The good news is that these types of attacks are not as effective as they used to be. Most of the traffic we send is now encrypted so the bad guys will struggle to get anything useful.
Dive deep into the world of network security with our comprehensive guide to the Address Resolution Protocol (ARP) and its vulnerabilities. 🌐 Discover how ARP works, from mapping IP to MAC addresses to the critical role it plays in network communication.
Learn about ARP poisoning, a stealthy attack where cybercriminals intercept and manipulate network traffic by sending fake ARP replies. Understand the dangers it poses, including data theft, session hijacking, and network disruptions.
Explore practical countermeasures: network monitoring tools, static ARP entries, IDS deployment, and more to safeguard your network. Stay secure by keeping software updated, using strong passwords, and implementing firewalls. Protect your digital environment with these essential tips!
