I have received an email in my reffmail account from the following mail id blsil@xkeyl.mediago.ca and next day again i got another mail from qrmjv@gvmoq.mediago.ca threatening that they will expause my personal intimate photo to my all friend circle if i dont pay them 1300 dollar within 48 hours as they have hacked into my system and they have all my information now. so please do let me know what should i do now. i have already raised a complain to cyber security department. i did not open any link given in the mail although i opened the first email. Am i at the risk. i have run norton security number of time but it is saying my system is safe. so please do let me know what should i do next.
