Method and apparatus for detecting computer-related attacks

A source node separated from a destination network by an original end to end path and configured to detect a computer-related attack affecting packets transmitted from said source node to said destination network, said destination network being associated with a prefix, said source node comprising:

• means for determining a current end to end path from said source node to said destination network;
• means for comparing said current end to end path and a reference node path from said source node to a reference node, said reference node located along said original end to end path and associated with a prefix different than said prefix associated with said destination network;
• and
• means for detecting a computer-related attack when at least a portion of said reference node path is not a sub-path of said current end to end path.

A computer readable medium comprising computer program instructions which, when executed by a processor, define steps for detecting a computer-related attack affecting packets transmitted from a source node to a destination network, said source node and said destination network being separated by an original end to end path, said destination network being associated with a prefix, said steps comprising:

• determining a current end to end path from said source node to said destination network;
• comparing said current end to end path and a reference node path from said source node to a reference node, said reference node located along said original end to end path and associated with a prefix different than said prefix associated with said destination network;
• and
• detecting a computer-related attack when at least a portion of said reference node path is not a sub-path of said current end to end path.
