Some research stuffs with Operational Technology (OT) Security

It’s probably been a good half a year since I last showed my face here, and now I’m dropping 2 or 3 blog posts in a row. It’s mostly just more research into CVEs and this one is no exception. The company gave us a target: either we punch this PLC, or we cannot sleep.

But because of that, my colleagues, my boss, and I were practically living in the lab. The result? We managed to find 7 bugs in Schneider Electric products. And hey, we got some sweet credit for it.

I also made it onto Schneider's official Wall of Thanks.

All in all, I've learned a ton working in this field. Honestly, I’m not sure if I’ll have time to keep up the research grind since I’m planning to get a cert at the end of the year, so things might get a little hectic. But I'll do my best to keep at it (mostly because the company keeps pushing me XD ).
