My girlfriend messaged me, asking if I had 4k. I quickly replied, "Yes, should I transfer it to you?" She requested an account number. I even inquired if she had been scammed. Subsequently, I called her to confirm the transfer, but she was shocked, claiming she had never messaged me. After checking, we discovered her WhatsApp had been hacked, as many of our common friends had also received similar messages. Fortunately, no money was lost due to my quick call to her.
