Human Stories
The Grok Build CLI incident perfectly captures what we're seeing across almost every story this week: our tools are becoming attack surfaces faster than we can map them. GitHub's ghost accounts and Wireless ADB exploitation both show attackers turning utility features into reconnaissance vectors, while AWS's new Network Scanning capability exists precisely because we've lost track of what we've exposed to the internet. What strikes me most is how the Russian intelligence operations targeting Signal users demonstrate that when direct technical attacks prove too difficult, adversaries simply move to the integration points and human layers we've left undefended. We're building increasingly sophisticated security controls for our infrastructure while the actual breaches are happening through API abuse, developer tooling that phones home, and social engineering against the very communication channels we use to coordinate incident response.
