The Black Hat and DEF CON security conferences will no longer be in-person this summer. Black Hat 2020 was scheduled for August 1st – 6th. DEF CON 28 was to follow it on August 7th – 9th. The event will now be held in an all-virtual format instead of being held in person. The global pandemic has caused concerns that there is no safe way of conducting the conferences in Las Vegas due to the health of the world and the lack of connectivity in the country.
