SQL Slammer Worm /Sapphire Worm


What is SQL Slammer?

  SQL Slammer Worm is the fastest worm in the world. It named SQL Slammer but it didn’t use any SQL language. This worm exploited some vulnerabilities of Microsoft's flagship SQL Server. SQL Slammer first appearance on 25-1- 2003. As I mentioned before SQL Slammer is the fastest worm. Most of the victims infected it within ten minutes. On 2003 in Hong Kong this worm cause ATM down and some of the Internet service down.

How SQL Slammer infect?

  SQL Slammer send the random target a UDP packet to port 1434. If the worm infected you system, it sends traffic to random ip addresses for DDOS the ip addresses to make the Internet service down and try to infect them. According to the record the traffic is up to 50Mb/s after being infected.

Solution?

  Michael Bacarella is the first person to alerted the general public. In 25-1-2003
Who posted a message "MS SQL WORM IS DESTROYING INTERNET BLOCK PORT 1434!".  And Microsoft releases the fix packet in 31-1-2003 to end this worm.

This is the infected area after the worm releases 30minutes
