The FBI investigated a man who allegedly posed as a police officer in emails and phone calls to trick Verizon to hand over phone data belonging to a specific person

Despite the relatively unconvincing cover story concocted by the suspect … Verizon handed over the victim’s data to the alleged stalker, including their address and phone logs. The stalker then went on to threaten the victim and ended up driving to where he believed the victim lived while armed with a knife

Version Security Assistance Team–Court Order Compliance Team (or VSAT CCT) received an email from [email protected].“Here is the pdf file for search warrant,” Glauner, allegedly pretending to be a police detective, wrote in the email. “We are in need if the this [sic] cell phone data as soon as possible to locate and apprehend this suspect. We also need the full name of this Verizon subscriber and the new phone number that has been assigned to her. Thank you.”

Verizon is not the only telecom that has failed to properly verify requests like this. In a somewhat similar case, I spoke to a victim who was stalked after someone posing as a U.S. Marshal tricked T-Mobile into handing over her phone’s location data.
