Ask HN: Ex-Employer alleging me for hacking. What should I do?

Looking for some guidance here. I was working in a startup for a few years. A few months back, we all received notices for salary cut since the startup was having some financial trouble. This didn’t change me much, but soon they started switching my role frequently, different languages and frameworks with vague requirements. I developed headache and soon I decided to leave them even if I didn’t have another job. I talked to my manager and told him that I’m leaving without serving notice period. I formally resigned and since then a few more devs left company. Unfortunately, at the same time, someone hacked their servers and I got a call asking for explanations. Others who left after me informed that they are still blaming me for this and some totally unrelated incidents. So here is me, a fullstack jobless engineer knowing most of the cool languages as well as plain old things that work and getting blamed of hacking I never did. What should I do and be careful of ? Sorry for lengthy text.
