In this day and age, wifi has become an integral part of our lives. We use it to stay connected with friends and family, to do work, and to access the internet. But many people don’t know that wifi is vulnerable to frag attacks, which can allow hackers access to our personal information. We will discuss frag attacks, how they work, and some ways to protect yourself from them.
What are frag attacks?
A frag attack, also known as a fragmentation attack, is a denial of service (DoS) attack targeting the fragment reassembly functionality of IP networks. The attacker sends fragmented packets to the victim system to overload it and prevents it from reassembling the fragments correctly. This can cause the system to crash or slow down, making it unavailable to legitimate users.
How do frag attacks work?
When a system receives a packet, it must first reassemble the fragments before processing the data. The attacker sends many small fragments to the victim system, which must reassemble the packets. This can cause the system to become overloaded and crash, or it can slow down the approach to the point where it is unusable.
What are some ways to protect against frag attacks?
There are a few things you can do to protect yourself from frag attacks:
- Keep your software up to date: Make sure you are running the latest version of your operating system and applications. Hackers often exploit known vulnerabilities in outdated software to launch attacks.
- Install a firewall: A firewall can help to block incoming traffic from malicious attackers.
- Enable IP fragment filtering: This feature can be enabled on some routers and firewalls to drop fragmented packets before they reach your system.
Frag attacks can devastate victim systems, but there are some steps you can take to protect yourself. Keeping your software up to date and using a firewall can make it much more difficult for hackers to launch an attack against you.
