Episode notes
Massive New DDoS Botnet Shifts Threat Scale
- Isoru's botnet reached ~4 million devices and fired a 29.7 Tbps UDP "carpet bombing" DDoS that Cloudflare absorbed.
- The scale dwarfs Mirai and raises urgent questions about infection vectors and global mitigation capacity.
Treat React RSC RCE As An Emergency Patch
- Immediately inventory apps using React Server Components and RSC-capable libraries and prioritize emergency changes.
- Patch affected NPM packages (React Server DOM 19.0–19.2) and investigate for possible unauthenticated RCE compromises.
Plan Minimal Business Continuity For Ransomware
- Run tabletop exercises and plan minimal viable operations to stay functional during ransomware outages.
- Prioritize fast recovery paths and identify core revenue services to restore first.
