However the threat presented by these attacks was grave enough to be classified as Cyber Defcon 4.\u00a0 \u00a0But on Friday Russia did indeed send tanks across the border into neighboring South Ossetia in conjunction with cyber attacks that have disable much of Georgia\u2019s ability to present their side of what is going on. The cyber attacks are attributed to the Russian Business Network (RBN) which has strong ties to the Russian Mafia, and thus the Russian government. RBN is responsible for much of the world\u2019s cyber woes. \u00a0one blogger tracking the attacks against Georgia.\u00a0 Thanks to the comments below for links to the RBNexploit blog.\u00a0 My own traceroute confirms that the Georgian Ministry of Foreign Affairs web site has DNS entries for a US hosting provider.\u00a0 But the website, www.mfa.gov.ge ,is still not responding.\u00a0 Anyone with more info please contact me!
