On January 1, 2017, Elephants and Donkeys suffered a major data breach and all of its stored data, including some personal information from residents of every state in the United States, were accessed and copied by hackers. Elephants and Donkeys, Inc. immediately launched an investigation into the nature of the breach, notified law enforcement, and implemented its data breach action plan.  About six months after the breach, Elephants and Donkeys, Inc. sent the following notice to all affected individuals via the United States Postal Service:   Dear Consumer, In January of this year, we suffered a major data breach.  Our investigation revealed that the breach was the result of Chinese State-Sponsored Hackers.  These hackers stole your data, including potentially your date of birth and social security number.  We’re very sorry that they stole the data, but we did literally everything we could to protect your data and prevent a breach.  We recommend that you monitor your credit reports for identity theft for at least the next year.   Sincerely, Stew N.
