Methods of Attack

• Viruses

• Viruses are probably the worst example of a Trojan Horse because they are embedded into an existing program, mainly in the header.

• The program header contain the most critical information such as location and size of segments (Text, data, stack).

• The header also contains the actual starting and ending addresses of the code.

• A virus modifies the header and adds its own header information such as start and end point, into the program's header.
