hello, few days ago I received 2 emails with subject “Bisso” and a pdf attouched to it. Both went to my spam folder and I never really paid any attention to it. Today I received another one that has added my phone number on the subject “Bisso & 123 XXX 789” where the first and last digits are my actual number. No text otherwise at all and same pdf attached. All 3 mails are from 3 different gmail accounts. I assume they got my mail and number from a leak and they trying to make me open the pdf?
