Here are 3 reasons why anyone should learn bug bounty huntingโ€”an ethical hacking course. (1) It doesn't require coding or prior hacking knowledge.ย  (2) It can be done from a smartphone, laptop, or at any location. (3) It requires no special tools or software.

Hello @moniepointng I am Yunus. Please do you have a bug reporting system? I'm not even asking about a bug bounty program but a bug reporting channel where a security bug discovered by the researcher is acknowledged by you, along with a (hopefully) quick attempt to fix it.

Talking about #cybersecurity is not attention-seeking! Some peopleโ€™s accounts and their other digital assets get #hacked every day due to a lack of awareness, and many of these victims do say, โ€œThey wish they were aware and informed before the cyber attack incident.โ€œ So, it's
