Chastity could become sex trap

A security flaw in an internet-connected male chastity device could allow hackers to lock it and trap wearers.

The Cellmate, made by Chinese firm Qiui and marketed as an anti-cheating and a submission sex-play device, is a cover that clamps on the base of the male genitals with a hardened steel ring.

It does not have a physical key or manual override - a lock is controlled with a smartphone app via Bluetooth. But researchers found flaws."We discovered that remote attackers could prevent the Bluetooth lock from being opened, permanently locking a user in the device," British security firm Pen Test Partners reports. "An angle grinder or other heavy tool would be required to cut the wearer free."

The firm found other security flaws in the Cellmate, listed at US$189 (HK$1,470).
