Less than a week into the new job and Uber's new CEO faces yet another federal investigation into the company. Sounds like hell. It is. The Federal Bureau of Investigation has launched a probe into secret software Uber used between 2014 and 2016 that was internally referred to as "Hell", The Wall Street Journal reported. The program could reportedly track Lyft drivers and was allegedly used to lure drivers back to Uber that were working for both the company as well as its competitor.
