What is a frag attack?

A frag (fragmentation and aggregation) attack either captures traffic toward unsecured networks to then clone and impersonate servers, or opens the network by injecting plaintext frames that look like handshake messages.

How do you prevent an IP fragmentation attack?

Users should make sure to check that their devices, including routers and network equipment, are up to date with patches and firmware. For businesses with a managed services provider who provides network security services, this is probably already being handled for you.

Attackers inject malicious packets of data to “punch a hole” in a router’s firewall if a connected device is vulnerable, allowing the attacker to unmask IP addresses and destination ports used to access the targeted device.

What causes IP fragmentation attacks?

To access your network via these vulnerabilities, attackers must be in radio range and have direct interaction with a user on the network. It also requires misconfigured network settings.
