IoT Everything

Jan 22, 2024

In the era of smart kitchens, WiFi-connected air fryers promise ultimate convenience: preheat your device from the office, monitor cooking progress via an app, or even integrate it with voice assistants like Alexa. Brands like Cosori, Xiaomi, and Aigostar offer models that let you control temperatures and timers remotely, turning a simple appliance into a “smart” hub. But from an information security standpoint, these devices introduce significant risks. While the convenience is tempting, connecting a high-heat appliance to your home network—and often the internet—opens doors to vulnerabilities that could compromise your privacy, network security, or even physical safety.

Real-World Vulnerabilities: The Cosori Case Study

One of the most notable examples comes from 2021, when Cisco Talos researchers discovered two remote code execution (RCE) vulnerabilities (CVE-2020-28592 and CVE-2020-28593) in the Cosori Smart Air Fryer (model CS158-AF). These flaws allowed attackers to inject malicious code, potentially altering temperatures, timers, or starting the device remotely. While some exploits required local network access, the risks were real: an attacker could overheat the device, posing a fire hazard, or use it as a foothold to pivot into your broader home network. Cosori eventually patched these issues via firmware updates, but the incident highlighted how IoT manufacturers often prioritize features over security. More recent concerns (2024-2025) focus on privacy rather than direct exploits. Consumer watchdog Which? tested smart air fryers from Xiaomi, Cosori, and Aigostar, finding that their apps requested excessive permissions—like precise location tracking and audio recording—without clear justification. Data from some models was sent to servers in China, raising espionage fears in online discussions.ts

Broader IoT Risks in Smart Appliances

Smart air fryers are part of the larger Internet of Things (IoT) ecosystem, where common issues include:

Weak Authentication: Default passwords or poor encryption make devices easy entry points. Unpatched Firmware: Many manufacturers stop updates after a few years, leaving known vulnerabilities exposed (Consumer Reports noted this as a major risk in 2024). Data Leakage: Apps collect usage habits, which could reveal when you’re home (or away), aiding burglars. Botnet Recruitment: Compromised devices can join massive networks for DDoS attacks. Network Pivoting: A hacked air fryer on your WiFi could expose computers, phones, or cameras.

In 2024-2025 reports, IoT attacks on home devices averaged 10 per day per network, with appliances increasingly targeted. Physical Dangers: More Than Just Data Theft Unlike a hacked smart speaker, an air fryer involves high heat (up to 400°F+). Remote control takeover could lead to overcooking, fires, or unsafe operation. While no widespread incidents have been reported, the potential is substantiated by expert warnings and past RCE flaws.

How to Mitigate the Risks

If you own or plan to buy a smart air fryer:

Isolate on a Separate Network: Use a guest WiFi or VLAN to segregate IoT devices from your main network. Update Regularly: Enable auto-updates and check for firmware patches. Strong Passwords & 2FA: Change defaults and use unique, complex credentials. Minimize Permissions: Deny unnecessary app access (e.g., microphone, location). Unplug When Not in Use: Reduces exposure, especially for always-on cloud-connected models. Choose Reputable Brands: Opt for those with good security track records (e.g., search “[brand] CVE” for vulnerability history). Consider Non-Smart Alternatives: Many top-rated air fryers (like Ninja or Instant Vortex) perform excellently without WiFi.

Final Thoughts: Convenience vs. Security

WiFi-connected air fryers exemplify the double-edged sword of IoT: incredible ease, but at the cost of expanded attack surfaces. While catastrophic hacks remain rare, the privacy intrusions and potential for network compromise are well-documented. As of late 2025, regulations like the UK’s PSTI are pushing for better security, but consumer vigilance remains key. If remote control isn’t essential, a dumb air fryer might be the smartest choice. Your crispy fries will taste just as good—without the side of cyber risk.
