WhatsApp Security Breach - Unauthorized Message from Unknown Number

I received a message saying "Hello" from a number with country code +62 on WhatsApp at 1:30 PM on 23.03.2024. Upon researching online, I discovered that this number is associated with India, a country with which I have no acquaintances or business relationships. I am extremely disturbed by this situation. I have blocked the number without opening the message content. I am definitely filing a complaint. I hereby declare that I do not accept any responsibility for the compromise of my account information, unauthorized use of my phone number, unauthorized access to my private information, messages, or photos, establishment of a company in my name, conducting transactions, or incurring debts in my name. All responsibility lies with WhatsApp.
