Twitter Warns Paying Customers of Potential Data Leak

Twitter is warning
paying customers of its advertising and analytics platforms in an email that it
is “possible” others could have accessed their personal and financial
information as a result of a bug.

As reported by BBC News, Twitter learned in May of a flaw in its platform that stored billing information of its clients in the browser’s cache. The company said it was “possible” others could have accessed that information, according to an email sent to clients obtained by the news network

The data in
question includes email addresses, phone numbers and the last four digits of
clients’ credit card numbers, the report says. Twitter claims there is
currently no evidence that clients’ billing information was compromised. The
issue affects mostly business clients who use Twitter’s paid advertising and
analytics modules.

Non-business
users don’t seem to be affected by the bug, which Twitter quickly patched.

“We’re
very sorry this happened,” the email says. “We recognise and appreciate the
trust you place in us, and are committed to earning that trust every day.”

The microblogging service is not at its first run-in with a serious bug in its platform. In 2019, a bug exposed phone numbers associated with millions of Twitter accounts. In another instance, the company was caught using multi-factor authentication phone numbers to target users with ads. And earlier this year, Twitter revealed a bug that caused direct messages to be stored in Mozilla Firefox browsers for up to seven days.
