I connected Windows XP to the Internet; it was fine

Hacker News Discussion ↗

Claims that a fresh Windows XP machine will be instantly compromised online are challenged by users who report trouble‑free use when the OS is placed behind a NAT router, kept off Internet Explorer, and paired with modern browsers and basic firewalls. Many argue that today’s threat landscape focuses on newer systems, and that widespread NAT, reduced prevalence of XP, and updated tooling make casual use relatively low risk, though they stress it remains unsuitable for sensitive tasks or exposure on a public IP. The exchange also branches into the broader security role of NAT vs. firewalls, legacy hardware and software needs, and the niche but persistent demand for XP-era systems.

Scope of “connecting XP to the Internet”

  • Many note a key distinction: XP with a public IP, open ports, and disabled firewall vs XP behind a NAT/router.
  • A YouTube “gets instantly owned” scenario is criticized as manufactured: public IP, file sharing/RDP exposed, firewall off.
  • Several argue the OP’s experience is unsurprising because most home setups now sit behind routers with default-deny inbound traffic.

NAT, firewalls, and “herd immunity”

  • Consensus: being behind NAT or a stateful firewall greatly reduces drive‑by network worms (e.g., Blaster era infections in seconds).
  • Some stress it’s state tracking/firewalling, not NAT itself, that provides protection.
  • Others push back, saying NAT effectively forces a firewall and hides internal topology, which users value.

XP vs modern OS security

  • One view: no modern OS would survive on the open Internet with multiple exposed services and no firewall.
  • Counterview: modern Linux/BSD/macOS (and current Windows) with patched services and auth can be safely exposed, at least against opportunistic attacks.
  • A minority report claims even up‑to‑date Debian servers picked up malware on the open Internet; others strongly doubt this without more detail.

Browser and application-layer risk

  • Big concern is outdated Internet Explorer and old plugins (Java applets, Flash, etc.) that used to be common infection vectors.
  • Modern hardened browsers, ad blockers, and avoiding Microsoft client apps on XP are seen as critical mitigations.
  • Some argue current web risks are more about tracking via JavaScript than classic destructive malware.

Targeting of legacy systems

  • Several suggest XP is now a low‑value target: botnets focus on newer OSes; exploit toolkits may not bother with Windows 98/XP.
  • Others reply that scanning for old OSes costs little and legacy vulns have a long tail.

Use cases, practicality, and nostalgia

  • XP still used for retro gaming, legacy hardware, and user familiarity; some refurbish and sell XP machines (often with pre‑applied updates and modern browsers).
  • Most agree XP should not be used for sensitive tasks, but is “fine” for constrained, hobbyist, or offline/behind‑NAT scenarios.
