WhatsApp Account Hacked – Unauthorized 6-Digit PIN Blocking Access

I have been using the WhatsApp mobile app linked to my phone number 951 380‑2*** without any issues until 14 August 2026. After that date, it appears that my WhatsApp account was hacked and the email address associated with it was changed without my consent. Now, whenever I try to open WhatsApp, I am immediately asked for a 6‑digit PIN. I never set this PIN myself and I cannot get past this screen to access my account or follow any of the help steps. Because of this security restriction, I am also unable to take a screenshot of the problem screen. I request that my account be urgently reviewed, the unauthorized 6‑digit PIN and any changes made by the third party be removed, and that I regain full access to my WhatsApp account. I also ask that any suspicious or unauthorized activity on my account be checked and reversed if possible. I expect this issue to be resolved as soon as possible, as I am currently completely unable to use my WhatsApp account.
