Three million malware-infected smart toothbrushes used in Swiss DDoS attacks

A viral claim that three million internet‑connected toothbrushes were hijacked to launch DDoS attacks on Swiss targets prompted scrutiny of both the story’s accuracy and the broader risks of “smart” devices. Commenters note that details are thin and later reporting suggests the toothbrush botnet was a hypothetical scenario that was misreported as fact, yet they argue the underlying threat is real given insecure, Wi‑Fi/Bluetooth‑enabled appliances with opaque data‑harvesting business models. Many call for stricter security requirements, clearer opt‑outs, and a re‑think of whether everyday objects like TVs, toothbrushes, and appliances need internet connectivity at all.

Reality of the toothbrush botnet story

  • Several commenters doubt the report: missing technical details, unclear which products, and no clear explanation of how toothbrushes got Wi-Fi access or joined botnets.
  • Others track the story back to a Swiss media piece citing a security vendor; later clarification from that vendor (quoted in the thread) suggests the scenario was hypothetical but “stretched” in translation.
  • Multiple comments conclude it likely “didn’t happen” as described, while still treating it as illustrative of IoT risk.

Why connect toothbrushes and other appliances?

  • Many question any need for internet-connected toothbrushes, fridges, ovens, TVs, air purifiers, etc.
  • Some see this as “experimentation”; others argue it’s mainly upsell and differentiation (“add Wi‑Fi and AI” to raise prices).

Data collection and business models

  • Strong focus on data monetization: toothbrush data plus identifiers (email, IP, phone) signals wealth, tech‑tolerance, and hygiene habits.
  • That profile can be sold to other appliance makers, retailers, dentists, travel services, etc.
  • Point made that there is “a market for any aggregate data on human behavior.”

Technical debates: Bluetooth, Wi‑Fi, and local vs cloud

  • Disagreement over whether brushes should sync via Bluetooth to phones, local LAN, or directly to cloud APIs.
  • Some argue local storage + periodic sync is enough; others say mobile OS background limits make direct Wi‑Fi more “reliable” for always‑up‑to‑date dashboards.
  • ESP32‑class chips and embedded Java are discussed as common, powerful but broad attack surfaces.

Home network security and responsibility

  • Commenters note UPnP, LAN‑side attacks via malicious web pages, and compromised routers as realistic IoT entry points.
  • Advice includes VLAN‑isolating IoT devices.
  • Strong pushback on putting the burden on non‑expert consumers to “monitor networks”; many argue manufacturers should be held responsible and possibly subject to regulation, liability, and minimum support lifetimes.

User experience and “smart” device backlash

  • Multiple anecdotes: smart TVs and appliances that won’t work or expose features unless online or account‑linked.
  • Frustration at devices that create permanent hotspots, can’t disable Bluetooth, or break when cloud services fail.
  • Nostalgia for simpler, offline devices and worry about lock‑in, surveillance, and eventual subscription models.
