This is Behind the Blog, where we share our behind-the-scenes thoughts about how a few of our top stories of the week came together. This week, we discuss OSINT for chat groups, Russell Crowe films, and storage problems.JOSEPH: On Wednesday we recorded a subscribers podcast about the second anniversary of 404 Media. That should hit your feeds next week or so. Towards the end of recording, I went silent for a bit. I said on air sorry about that, a source just sent me an insane tip, or something like that.That tip led to ICE Adds Random Person to Group Chat, Exposes Details of Manhunt in Real-Time. Definitely read the piece if you havent already. It presented an interesting verification challenge. Essentially I was given these screenshots which included phone numbers but I didnt know exactly who was behind each one. I didnt know their names, nor their agencies. It sure looked like a conversation involving ICE though, because it included a Field Operations Worksheet covered in ICE branding. But I needed to know who was involved. I didnt think DHS or ICE would help because they are taking multiple days to reply to media requests if they do at all at the moment. So I had to do something else.
