Critical Security Flaw in Smart Chastity Device Risked Permanent Lock-In
The Dangers of Poor IoT Security
Internet-connected devices promise convenience, but weak security can turn them into liabilities. A recent discovery by cybersecurity researchers revealed how a flaw in a popular “smart” chastity device could have left users permanently locked—with alarming consequences.
The Qiui Cellmate Vulnerability
U.K. cybersecurity firm Pen Test Partners uncovered a severe security flaw in the Qiui Cellmate, marketed as the “world’s first app-controlled chastity device.” The device allows partners to remotely lock and unlock the chamber via Bluetooth using a mobile app. However, researchers found that the app’s API was left completely unsecured, exposing users to remote hijacking.
Key Risks Identified:
- Remote Locking: Attackers could permanently lock the device, trapping the wearer.
- No Emergency Override: No failsafe mechanism existed to manually unlock the device.
- Data Exposure: Hackers could access private messages and real-time user locations.
“An attacker could lock everyone in or out very quickly. There’s no emergency override function—if you’re locked in, there’s no way out.”
— Alex Lomas, Pen Test Partners
Failed Fixes and Delayed Responses
TechCrunch first learned of the vulnerability in June 2020. Despite repeated warnings, Qiui failed to address the issue promptly:
- The company pushed a new API for new users but left the vulnerable one active for existing customers.
- Missed three self-imposed deadlines to resolve the flaw.
- CEO Jake Guo cited development challenges, stating, “When we fix it, it creates more problems.”
Real-World Impact
While no confirmed malicious exploits were reported, user reviews highlighted alarming incidents:
- “The app stopped working completely after three days, and I am stuck!”
- “I almost got stuck in it. Thankfully, it unlocked randomly, but it left a bad scar.”
A Pattern of IoT Security Failures
This isn’t the first time smart sex toys have faced scrutiny:
- 2016: A Bluetooth vibrator was found hackable, allowing remote control.
- 2017: A smart toy maker settled a lawsuit over unauthorized data collection.
Lessons Learned:
- IoT devices require robust security—especially those with physical safety implications.
- Manufacturers must prioritize timely patches to protect users.
- Consumers should weigh risks before adopting connected intimate devices.
Final Thoughts
The Qiui Cellmate flaw underscores a broader issue: not every device needs to be “smart.” Without proper safeguards, connectivity can lead to dangerous—and sometimes irreversible—consequences.
