A location-tracking smartwatch worn by thousands of children has proven relatively easy to hack.
A security researcher found the devices neither encrypted the data they used nor secured each child’s account.
As a result, he said, he could track children’s movements, surreptitiously listen in to their activities and make spoof calls to the watches that appeared to be from parents.
Experts say the issues are so severe that the product should be discarded.
Both the BBC and the researcher involved tried to contact the makers of the MiSafes Kid’s Watcher Plus to alert them to the problem but received no reply.
Likewise, a China-based company listed as the product’s supplier did not respond to requests.
