Jeremy Kirk

Former Information Security Journalist



I'm a former cyber security journalist now working for Intel 471, a cyber threat intelligence company. As a journalist, I wrote news and opinion and conducted video and audio interviews. I worked for International Data Group, now called Foundry, in South Korea, the U.K and Australia and also the Information Security Media Group from Australia. This website catalogs some of my writing as a journalist from those jobs. I also created The Ransomware Files, a podcast about IT professionals fighting back against ransomware, one of the greatest crime waves to ever affect the internet.
