Venmo’s Public Transactions and Friend Lists
Ryan Mac et al. (via Nick Heer):
On Friday, following a passing mention in the New York Times that the president had sent his grandchildren money on Venmo, BuzzFeed News searched for the president’s account using only a combination of the app’s built-in search tool and public friends feature. In the process, BuzzFeed News found nearly a dozen Biden family members and mapped out a social web that encompasses not only the first family, but a wide network of people around them, including the president’s children, grandchildren, senior White House officials, and all of their contacts on Venmo.

While many critics have focused on how the app makes all transactions public by default, Venmo’s friend lists are arguably a larger privacy issue. Even if a Venmo account is set to make payments private, its friend list remains exposed. There is no setting to make this information private, which means it can provide a window into someone’s personal life that could be exploited by anyone — including trolls, stalkers, police, and spies.

Using public friend lists and transaction feeds, BuzzFeed News found two members of Congress who were roommates in Washington, DC, as well as reporters who were on friend lists with Trump administration officials, potentially exposing their sources. BuzzFeed News has also spoken with survivors of domestic violence and abuse who suspected that former partners used Venmo to track them and therapists who use Venmo to receive payment from clients and were unaware their friend lists showed who they were working with.
