A security flaw in a hi-tech chastity belt for men made it possible for hackers to remotely lock all the devices in use simultaneously.
The internet-linked sheath has no manual override, so owners might have been faced with the prospect of having to use a grinder or bolt cutter to free themselves from its metal clamp.
The sex toy’s app has been fixed by its Chinese developer after a team of UK security professionals flagged the bug.
They have also published a workaround.
This could be useful to anyone still using the old version of the app who finds themselves locked in as a result of an attacker making use of the revelation.
Any other attempt to cut through the device’s plastic body poses a risk of harm.
Pen Test Partners (PTP) – the Buckingham-based cyber-security firm involved – has a reputation for bringing quirky discoveries to light, including problems with other sex toys in the past.
It says the latest discovery indicates that the makers of “smart” adult-themed products still have lessons to learn.
“The problem is that manufacturers of these other toys sometimes rush their products to market,” commented Alex Lomas, a researcher at the firm.
“Most times the problem is a disclosure of sensitive personal data, but in this case, you can get physically locked in.”
Lock and clamp
Qiui’s Cellmate Chastity Cage is sold online for about $190 (£145) and is marketed as a way for owners to give a partner control over access to their body.
