• "The New York Times was able to track the movements of President Donald Trump using cellphone data.
  • The Times used leaked phone data to track the movements of someone in his entourage, who believe is a Secret Service agent, as well as his name and home address.
  • The Times said it replicated the exercise and identified workers at numerous sensitive sites in Washington, D.C., including the Pentagon, Supreme Court and Capitol Hill."
  • The ease with which non-experts at the Times could do this shows the extreme vulnerability in location data. Hostile states are almost certainly able to do far more."

"The Times – which said it got the data from anonymous whistleblowers concerned about this vulnerability and a lack of regulations – said it took only minutes to turn a massive anonymized dataset into specific information on Trump.
The Times said it got data from 50 billion location “pings” from the phones of more than 12 million people in the US, relating to their movements in 2016 and 2017."

"This person’s movements outside work hours could also be tracked, the Times said – leading to a home address, a name, and identities for family members. The Times did not publish this information.

The Times also said that it could track people in locations like the White House, Capitol Hill, the Supreme Court, the Pentagon, military bases, and the FBI headquarters. This also led to verifiable home addresses and names."

Perphaps posting this in the Futurism subforum is not fair, since this is practice based on today's technology.
But if someone like Trump can be tracked by "amateur" technology journalists... imagine what can be done with the data of the common pleb...

"The Times observed that such data could lead to potentially compromising information, like evidence of extramarital affairs, medical problems, and the like.

It said it identified one person who frequently in the Pentagon as someone who also made visits to a mental health and substance abuse facility."
