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.

Update (2024-07-22): Dhruv Mehrotra, Tim Marchman, and Andrew Couts:

US senator J.D. Vance, an Ohio Republican and former US president Donald Trump’s pick for vice president, has a public Venmo account that gives an unfiltered glimpse into his extensive network of connections with establishment GOP heavyweights, wealthy financiers, technology executives, the prestige press, and fellow graduates of Yale Law School—precisely the elites he rails against. A WIRED analysis of the account, the people listed as Vance’s friends, and, in turn, the people listed as their friends highlights sometimes bizarre and surprising connections. Experts, meanwhile, worry that the information revealed by the peer-to-peer payment app raises the potential for stalking, trolling, and impersonation.

Nick Heer:

It is still so deeply bizarre to me that many Americans rely on a peer-to-peer banking app that was historically public by default.

Venmo is widely supported and works really well. It’s much better than PayPal or Apple Cash. So I don’t find its traction surprising, though I’m surprised that more people don’t bother to turn off public transactions.
