Cybersecurity professionals uncovered vulnerabilities that canceled the anonymity associated with Twitter's Tip Jar feature, Wired reports. Researchers found the new payment feature, which links Twitter accounts to online payment platforms, carried system errors that would reveal the tipper's home address and email address associated with their PayPal account. A Twitter spokesperson said the company would update its in-application notification to clarify Tip Jar "may share information about people sending tips to one another."
