The Case for Ephemeral Resolvers: Securing the Global Namespace

Phoenix Substack • 56 implied HN points • 09 Jan 26
🕹 Technology Internet DevOps Networking Cybersecurity Infrastructure Cloud Software
  1. Make DNS resolvers ephemeral so attackers have at most a short window to exploit them; rotating instances every ~15 minutes evicts compromises before they can be weaponized.
  2. Leverage PowerDNS’s modular stack—dnsdist as a stable front, database-backed authoritative servers, and shared-memory for recursive state—to rotate backend workers quickly without cache cold-starts.
  3. At scale this model adds minimal overhead (under 2% CPU) and changes security from reactive patching to proactive eviction, greatly raising the cost and shortening the lifespan of zero-day attacks.

  2. Lode Runner Extra has extra unique codes too — entering SATURNSUPER then holding R at start loads a different bonus level (the Saturn Super demo disc stage) — and a GODAI@TECHARTS string is present in the code but only partially implemented in The Legend Returns.
  3. The cheats are implemented as ASCII name checks, which made them straightforward to find by reverse engineering, and the NTSC-U PlayStation release includes the SPECIAL! code but not the same credits-skip button sequence.
