SQL Slammer

 

SQL Scammer sparked on January 25, 2003, when it infected its first server. After it, the infection spread rapidly, having infected more than 70,000 computers after the release into the wild. This worm exploited a bug in Microsoft’s SQL Server as well as Desktop Engine database products. As it spread quickly, it severely slowed down worldwide internet traffic, which resulted in the collapse of important systems, and it caused panic and significant damage. 

What is remarkable is that the patch that could have prevented the spread of this infection was released 6 months prior to the incident itself. However, those companies that were affected merely ignored the recommendation to install it.

The boot sector was moved to another sector and marked as bad. Meanwhile, text was written into the infected sectors, which, remarkably, included the virus authors’ names and telephone numbers.

  Tinba was first discovered in 2012. The name stands for the Tiny Banker Trojan. As a modified version of older Banker Trojans, it was developed to target the websites of financial institutions.

Tinba is based on network sniffing and man-in-the-browser attacks. It is indeed tiny — 20 KB — and it is what made the Trojan difficult to detect.
