"By the time I went to bed [on Tuesday], I had identified nineteen different devices, each tied to BlueToad in some way," Schuetz wrote Monday in a . "One, appearing four times, is twice named 'Hutch' (their CIO), and twice named 'Paul's gift to Brad' (Paul being the first name of the CEO, and Brad being their Chief Creative Officer). I found iPhones and iPads belonging to their CEO, CIO, CCO, a customer service rep, the Director of Digital Services, the lead System Admin, and a Senior Developer."

Schuetz informed Bluetoad of his findings on Tuesday. The company asked for some time to investigate and confirmed on Friday that it was the source of the leaked data, Schuetz said. The two parties then agreed to make coordinated public disclosures on Monday.

Bluetoad has notified law enforcement about the security breach and is cooperating with their ongoing criminal investigation of the parties responsible, DeHart said.

The company has fixed the vulnerability exploited by the hackers and engaged an independent security assurance company to help it ensure that such an incident doesn't happen again, he said.

"We understand and respect the privacy concerns surrounding the data that was stolen from our system," DeHart said. "BlueToad believes the risk that the stolen data can be used to harm app users is very low."
