The Difficulty of Saying Nothing

Like everyone else I’ve been following the tragic war in Ukraine and mourning the loss of life and humanitarian crisis. Professionally as an analyst in the threat intelligence and computer network defense world I’ve been considering what this war and spillover means for defending networks, especially as organizations like CISA keep putting out bulletins regarding threats of Russian nexus adversaries.

Familiarity Breeds Contempt: APT Edition

Here’s a familiar scenario: A new threat is being whispered about. Maybe your office has someone with special access of some kind and they’re being a bit more secret squirrely than usual. The mailing lists you’re on are a buzz about a new piece of malware or vendor code name. You keep hearing about a paid only report that tells all. APT 46: EMPEROR PENGUIN is coming!
