On Friday, someone sent an online message to Snapchat's accounting department requesting information on employees on behalf of CEO Evan Spiegel. And an employee actually sent out this information to a faceless, nameless person on the other side of the internet connection. And it only was after the information was sent that the employee decided that she had better double-check this request with Spiegel himself. Luckily, no private data was involved, and it was determined Snapchat was not under any more "attacks."
Snapchat ended up sending out a letter to affected employees, offering them two free years of identity-theft insurance and monitoring. Employees will be re-trained to prevent this from happening in the future. Let this be a lesson to to you. If you get a request that is out of the ordinary, double-check it first before complying with it.
