This week, the Justice Department indicted a 22-year-old on charges of tampering with the water facility where he used to work. It's a stark reminder that while the power grid gets most of the attention, it's not the only piece of critical infrastructure that's vulnerable to potentially devastating attacks. We also took a look at YouTube's ongoing problems with moderating kid-focused content; a WIRED investigation found dozens of creepy thumbnails on videos for Minecraft and child-centric pursuits that were at or near the top of the platform's "Topic" pages. It's not quite as dire a situation as the so-called Elsagate controversy from a few years back, in which the YouTube Kids app was flooded with grotesque videos featuring popular children's characters performing unspeakable acts. But it still shows that YouTube has a lot of moderation work still ahead of it.
