Fahmida brings over a decade of IT security news reporting along with ten years of network administration and software development to Decipher. Every security story has a human face, and her goal is to bring those stories to light. As the senior managing editor of Decipher, she will focus on ways security can impact how people live, work, and play. She enjoys working on stories that speak to those outside the security industry, highlighting the intersection of security and other technology areas. Over the years, she has seen enough to make her overzealous about her personal threat-model, but she doesn’t hold it against anyone for having a more relaxed worldview.

Think webcams, printers, smart light bulbs, industrial control systems, monitoring systems. Information about these devices are just a special search query away.
We still don't know who was behind the Olympic Destroyer malware that targeted South Korea during the Winter Olympics, but we know all those supposed clues to their origins were false clues planted by the attackers. As defenders, assume everything you can't verify completely is a lie the attackers deliberately crafted.
