If they are going from a whois database or abuse contact, an email address might be all they have.
I remember many years ago I sold T1 service to the FBI, actually the Chicago Cybercrime task force, joint with Chicago PD. I think they used it for sting operations or something, didn’t want an IP address that would like like government or LEA. They were just ordinary folks trying to do a job. I would not rule out that they would contact you by email. Or that the inquiry would not involve a court order but just investigating a lead. It was kind of funny when I went there to install the service. Lots of trim young men in suits looking exactly like you’d expect an FBI agent to look, and lots of not so trim not so young men in blue looking like you’d expect a Chicago cop to look. The FBI guys looked like Josh Brolin (young K) from MIB, the cops didn’t quite look like Will Smith. I don’t remember anybody looking like Alice Eve, I’d remember that. Also many years ago I remember an FBI agent knocking on the office door, was doing outreach to ISPs, just wanted to explain what they did and who to call about what and leave a business card. Actually very nice. I think a lot of “deep state” workers get a bum rap.

I am doubtful that the FBI would contact you via email. Most likely they would send you a letter (assuming the USPS could deliver it). If they're actually serving you a subpoena, I would expect agents or some legal officer would issue it to you in person. I would file it in the same category as this voice mail I got yesterday: Listen to this message carefully, this message is to inform you that SSA and legal enforcement agency is filing a legal warrant against your name and your Social Security number for fraudulent activities and arrest em has also been issued on your name for money laundering and the investigating team of our department is investigating you and your family to get more information about your arrest warrant in case File from United States government. You may press one for more information before we download your case into the courthouse. Thank you, press one now. bp <part15sbs{at}gmail{dot}com> On 9/18/2020 11:49 AM, Nate Burke wrote: I got this message to the INFO mailbox of a company we acquired a year ago. Everything about it says that it's spam, but the headers look legit. Although the 153.31.119.142 IP address does not exist in the ARIN whois. BGP.he.net says that it's part of a /17 assigned to the FBI. It has an attached PDF that I have not yet opened. (file name SBP634366-WOW125412.pdf) I can't imagine this is anything other than Spam/virus? Is it possible this is how the FBI Actually sends out things? What's the best way to open a suspect PDF File? _____________________ *** CHILD EXPLOITATION *** Good afternoon - please review the attached administrative subpoena and proceed accordingly - thank you and have a great weekend!
