What is the name of the teenager hacker group that allegedly stole passwords and data from phone companies in the early 1990s?

Masters of Deception and Legion of Doom were two bands of teenage hackers that were active in the 1980s and eventually caught in the early 1990s. Legion of Doom (LOD) was a group of Southern hackers who broke into BellSouth's 911 network to steal login-ins and passWords, possibly interfering with emergency call service as well. Masters of Deception (MOD) was based in New York and hacked the computer systems of several companies, including AT&T and Bank of America. Five of their members were arrested in 1992.
