Mara was a victim of identity theft, and just narrowly avoided having her brokerage account drained. Leo says that Mara should change her password and turn on 2 factor authentication right away. Leo suspects the bad guys got her information from a database breach like the Collection #1 or the Marriott hack. Leo also suggests going to haveIbeenpwned.com/passwords and see if her passwords have been compromised and are known. Leo also recommends having a credit freeze put on Mara's account using Equifax, Experian, and TransUnion. That will prevent any additional credit accounts being opened in her name.
