Black Hat and DEF CON, the two biggest cyber-security conferences of the year, have canceled their in-person events today and announced plans to go with a virtual conference format in light of the COVID-19 (coronavirus) pandemic.
The two conferences were initially scheduled to take place in Las Vegas back to back in the first two weeks of August 2020, with Black Hat from August 1 to August 6, and with DEF CON from August 7 to August 9.
