Rodney Joffe is a South African-American entrepreneur and cybersecurity expert.[2] He is a recipient of the FBI's Director's Award for Outstanding Cyber Investigation for his role in uncovering the Mariposa botnet. He is also one of four people who investigated apparent communications between computer servers at The Trump Organization and Alfa-Bank in Russia.
Even though Joffe's firm had a cybersecurity contract with the Executive Office of the President (EOP) to keep track of its DNS traffic after the Russian hacking of White House networks in 2015 and 2016, Special counsel John Durham alleged in February 2022 that Joffe had exploited his access to internet traffic from Trump Tower and the White House to seek derogatory information on Donald Trump.[3][4]
