Nuke attack

Nukes are Window crashes caused by dimwitted users (who know your IP address) who decide to use a Windows 95 (not 98) bug where if someone repeatedly sends information packets to port 139, Windows displays a lovely and impressive blue screen and you need to restart your computer.

To protect yourself, there are patches that make it possible to correct the bug.

Flooding

Flooding involves quickly sending large information packets to a person, as long as the PING (the time the information takes to make one round trip between 2 machines) is very short. The targeted person will no longer be able to respond to requests and the modem will disconnect.

One solution to this problem is to not reveal your IP address.

TCP/SYN flooding

During a TCP connection, the client and the server exchange data and acknowledgements to establish the connection. This mechanism is called the three-way handshake.

TCP/SYN flooding

This mechanism has a weakness when the server sends a SYN-ACK (synchronization acknowledge) but does not receive an ACK (acknowledgement) from the client. In this case, the server creates a data structure containing all open connections (taking up space in memory). While it is true that there is an expiration mechanism that makes it possible to close connections that have been open for too long and therefore free up memory, an attacker can quickly flood the memory if he sends SYN packets fast enough.

In addition, the attacking system generally provides a return address of a computer that is not able to respond. As a result, it is extremely difficult to know where the attack is coming from...
