Russian Cyberwar

21st Century Warfare:

The Georgian embassy in the U.K. has accused forces within Russia of launching a coordinated cyberattack against Georgian Web sites, to coincide with military operations in the breakaway region of South Ossetia.

Probably a fairly easy thing to do knocking out your enemy's websites with denial of service attacks while at war. And probably just as easy to recover against.

I would be more impressed if Russia has accessed Georgia's defense network and done mischief.
