Episode notes
Cloud-Scale DDoS Is The New Normal
- DDoS attackers now leverage cloud-scale outbound bandwidth to launch ultra-short, ultra-intense floods.
- Defenders must match scale with instant automation, rate limiting, and massive capacity to stay online.
Make DDoS Mitigations Instant And Layered
- Implement automation, rate limiting, and IP filtering as baseline DDoS defenses.
- Monitor for smaller persistent or multi-vector attacks that can bypass size-focused measures.
Zero-Click Defeats Device-Level Security
- Zero-click exploits let attackers compromise devices without user interaction and defeat end-to-end encryption by accessing data on the device.
- Such attacks are highly targeted but could be used against any high-value individual.
