Blaster Worm
Blaster (also known as Lovsan, Lovesan, or MSBlast) was a computer worm that spread on computers running operating systems Windows XP and Windows 2000 during August 2003. The worm was first noticed and started spreading on August 11, 2003. The rate that it spread increased until the number of infections peaked on August 13, 2003. Once a network (such as a company or university) was infected, it spread more quickly within the network because firewalls typically did not prevent internal machines from using a certain port.

Hex Dump
In computing, a hex dump is a textual hexadecimal view (on screen or paper) of computer data, from memory or from a computer file or storage device. Use of a hex dump of data is usually done in the context of either debugging, reverse engineering or digital forensics. Interactive editors that provide a similar view but also manipulating the data in question are called hex editors. In a hex dump, each byte (8 bits) is represented as a two-digit hexadecimal number. Hex dumps are commonly organized into rows of 8 or 16 bytes, sometimes separated by whitespaces. Some hex dumps have the hexadecimal memory address at the beginning. On systems where the conventional representation of data is octal, the equivalent is an ''octal dump''. Some common names for this program function are hexdump, hd, od, xxd and simply dump or even D. Samples The following sample shows output from unix program hexdump, other systems have programs which generate similar output. 0123456789ABCDEF /* ...
