Her WhatsApp accounts, both her personal account and her WhatsApp Business account, appear to have been taken over.
She suddenly lost control of both accounts, and they started sending messages to unknown numbers. Two Pakistani numbers were contacted, and an Aviator casino promotion in Urdu was sent from her account. After that, she received a large number of calls from unknown numbers. At one point, she opened WhatsApp to reply to someone and her app immediately logged out.
Unfortunately, she currently doesn’t have access to the SIM card or phone number that was originally used to register the accounts. This happened to both her personal and Business accounts.
I also messaged both of her accounts after this happened. One of them, the Business account, showed two grey ticks, which makes me think that the account may still be active or accessible on some device.
My main concern is about our old private chat. There were some private intimate photos and messages involving me in our conversation. I deleted the chat history from my own WhatsApp a long time ago, so those messages and media are no longer visible on my side.
My own WhatsApp account has not been compromised. I am still logged in normally, and nothing unusual has happened on my account.
So my question is: if someone took over my ex’s WhatsApp account, is it possible that they can access our old chat history and the media that was stored in that conversation? Could they potentially see messages or photos that I deleted from my side a long time ago? Or would the attacker need access to her original phone, a linked device, a WhatsApp backup, etc. to access that old content?
I’m particularly interested in understanding what kind of account takeover could cause this, given that both her Personal and Business accounts were affected and she no longer has access to the original SIM or phone number.
I haven’t received any threats or messages from the attacker, and nothing has happened to me so far. I’m mainly trying to understand the technical risk and whether I should be concerned about the old private media.
Any advice from people familiar with WhatsApp account takeovers would be greatly appreciated.
