Twitter Asked to Tell Reality Winner the FBI Had Obtained Her Social Media Activity
Last week, the Augusta Chronicle reported that the government had unsealed notice that it had obtained access to Reality Winner’s phone and social media metadata. Altogether, the government obtained metadata from her AT&T cell phone, two Google accounts, her Facebook and Instagram accounts, and her Twitter account. Of those providers, it appears that only Twitter asked to tell Winner the government had obtained that information. The government obtained the 2703(d) order on June 13. On June 26, Twitter asked the FBI to rescind the non-disclosure order. In response, FBI got a 180-day deadline on lifting the gag; then on August 31, the FBI asked the court to unseal the order for Twitter, as well as the other providers.
The applications all include this language on Winner’s use of Tor, and more details about using a thumb drive with a computer last November.
During the search of her home, agents found spiral-bound notebooks in which the defendant had written information about setting up a single-use “burner” email account, downloading the TOR darkweb browser at its highest security setting, and unlocking a cell phone to enable the removal and replacement of its SIM card. Agents also learned, and the defendant admitted, that the defendant had inserted a thumb drive into a classified computer in November 2016, while on active duty with the U.S. Air Force and holding a Top Secret/SCI clearance. The defendant claimed to have thrown the thumb drive away in November 2016, and agents have not located the thumb drive.
Given that the FBI applied for and eventually unsealed the orders in all these cases, it provides a good way to compare what the FBI asks for from each provider — which gives you a sense of how the FBI actually uses these metadata requests to get a comprehensive picture of all the aliases, including IP addresses, someone might use. The MAC and IP addresses, in particular, would be very valuable to identify any of her otherwise unidentified device and Internet usage. Note, too, that AT&T gets asked to share all details of wire communications sent using the phone — so any information, including cell tower location, an app shares with AT&T would be included in that. AT&T, of course, tends to interpret surveillance requests broadly.
Though note: the prosecutor here pretty obviously cut and paste from the Google request for the social media companies, given that she copied over the Google language on cookies in her Twitter request.

Out of ATT, Google, Facebook, Instagram and Twitter, how many really have ‘local and long distance telephone connection records’?
The first two obviously do.
Which leads me to posit this question:
Are all TLS three-way handshakes being fed into SS7?
Mea culpa. I should not have said TLS, when plain TCP will do. I.E., it can be a plain HTTP connection, it does not need to be HTTPS for example.
The point is, the TCP three-way handshake reveals critical metadata. The ip addresses and ports on both ends. Finding SYN packets, SYN-ACK packets, and ACK packets is trivial. Easy to capture and feed to an external system like SS7. Low overhead.
