WhatsApp may be facing its second bug this week, potentially putting users’ private messages at risk of being exposed without their knowledge.
Amazon Web Services employee Abby Fuller shared worrying details about the flaw on Twitter, revealing how the message history of a previous owner popped up on her phone after logging in with a new number.
As of now, it’s unclear if Fuller is the only WhatsApp user to have been affected by the issue, or if she’s simply the first to notice.
Fuller detailed the issue on Twitter this week, where she was instantly bombarded with suggestions and possible explanations from other users.
But according to Fuller, the device was brand new and nothing she did in the setup appears to have prompted it.
‘Logged into WhatsApp with a new phone number today and the message history from the previous number’s owner was right there?! This doesn’t seem right,’ Fuller tweeted on Thursday.
‘And now I’m wondering how many other times it’s happened? Like does whoever has my old number now have MY WhatsApp history?’
‘Yes it was a new device. No it wasn’t second hand. It was not a second hand SIM. Yes I’m sure they weren’t my messages, or groups that I was added to. Yes they were in plaintext. I am sure it’s my phone number. It was not restored from a backup,’ Fuller added.
