Ask HN: What are current problems or trends regarding cybersecurity?

I am asking for possible subjects and ideas for my cybersecurity bachelor thesis. I have 10+ years of experience as fullstack dev and sysadmin. I have been following HN for a long time and learned so many things. I am not expecting a thesis idea, but a discussion would definetely help me think about possibilities and widen my horizon. I already have few items in my list, but I can't find any of these strong enough, because they are either too general or too vague: - Container (Docker, etc) security - Media originality check (eg anti-deep fake or propaganda) - Security of IoT data, especially in cloud - Security of health care (don't know how)
