🔴 You buy a Wi-Fi repeater and find yourself with a hacker roommate with root credentials

A Wi-Fi extender costing just €3 turned out to be a device with a pre-configured hidden login for complete system control. Penetration testing specialist Kiran Smith purchased an unnamed signal booster from Temu and discovered an undocumented root account with an identical password across the entire set. Changing the default administrator password didn't solve the problem: with every reboot, the extender resets the secret credentials.

The device was sold as a six-antenna signal booster with no clearly identifiable model or manufacturer.
