21 Jul Venmo Makes User Transactions Public, Offers No Explanation
Berlin-based privacy researcher Hang Do Thi Duc recently discovered that the transactions made on Venmo are “public” by default and was broadcast on Venmo’s API.
This means that all the instances someone sends or receives money using the PayPal-owned mobile app (which had over seven million users in 2017) would be visible to anyone even without the app.
Do Thi Duc said that by pulling public transactions using Venmo’s API, he was able to follow a drug dealer’s sales, watch a couple fight viciously on Valentine’s Day, and learn exactly how many mangos a Santa Barbara, CA food cart sells each week.
Venmo, however, did not provide an explanation or give a comment on the matter.
