Users of credit monitoring site Credit Karma have complained that
they were served other people’s account information when they logged
Many took to a Reddit thread and complained on Twitter about the
apparent security lapse.
“First time logging in it gave me my information, but as soon as I

Credit Report tab with that user’s personal information, like names
and addresses, was blank.
One user said that the login page was pulled offline for a brief
period. “We’ll be right back,” the login page read instead.
Credit Karma spokesperson Emily Donohue denied there was a data
breach, but when asked would not say how many customers were affected.
“What our members experienced this morning was a technical malfunction
that has now been fixed. There is no evidence of a data breach,” the
The company didn’t say for how long customers were experiencing issues.
Credit Karma offers customers free credit score monitoring and
reports. The company allows users to check their scores against
several major credit agencies, including Equifax, which last month was
fined at least $575 million for a 2017 data breach.
