The White House this week released a plan to stop state sponsored hacking, like the one uncovered by Mandiant this week, through the use of diplomatic pressure. The 72 page report details the measures that the White House is willing to use as leverage. The strategy stops short of threatening economic or other types of sanctions.
No word yet from the hackers on whether they will lay down their compilers. A more likely response will be that they install malware into the PDF of the report. Sorry if you already clicked the link. I can picture the hackers learning to say “Diplomatic Immunity” a la Lethal Weapon 2.
