Last month’s demonstration of a smart-home takeover made one thing clear: we can no longer treat internet-connected devices as benign conveniences. In a video circulating online, a woman carefully avoided stepping into the camera frame, yet her abode was nonetheless compromised.
A casual selfie taken by a friend fed into a facial recognition system; her identity was swiftly confirmed and her home network was penetrated. The doorbell chimed on command, lights flickered, the television blared to disorient, surveillance cameras streamed private moments and her personal documents were exfiltrated, all before she knew what hit her.
Worse still, a message was sent from her e-mail account, casting doubt on her integrity. This was no careless user error; it was a stark illustration of systemic vulnerability born of design decisions that prize ease of use over security.
Zimbabwe’s Postal and Telecommunications Regulatory Authority (Potraz) must act now to forestall such incursions into every corner of our homes.
Smart-home technologies are proliferating across Harare’s new suburbs, Bulawayo’s leafy crescents and even in townships where prepaid solar-powered routers are gaining ground. From remote-controlled lighting and smart meters to intelligent door locks and voice-activated assistants, Zimbabweans are embracing IoT (internet of things) devices in the name of comfort, energy efficiency and peace of mind. Yet each gadget that bolts onto our home network also widens the attack surface available to cyber-physical adversaries.
Without robust oversight, the very frameworks designed to simplify life can become conduits for surveillance, extortion and privacy invasion.
The root of the problem lies in fragmented regulation and endemic under-securing of devices. Manufacturers favour rapid time-to-market, shipping products with default passwords, unencrypted channels and opaque software-update policies. Consumers, often unaware of the hidden risks, plug in smart sensors and cameras, configure them with predictable credentials and grant remote-access permissions with a single tap. From that moment on, they forfeit control of their homes to an ecosystem engineered for maximum data capture.
Consider the intrusion in the viral video. First, passive data capture: a facial recognition engine continuously scans networked feeds. Second, identity linkage: a third party image — hers in a group photo — becomes the key to decrypting personal profiles.

Third, lateral movement: once inside the network, the attacker, or malicious code, traverses from the innocuous smart doorbell to the home automation hub, unlocking doors and hijacking AV equipment.
Fourth, data exfiltration: private photographs and sensitive directories are siphoned out and used to impersonate the homeowner online. The seamless chain of events exposes every layer of weakness in the typical smart-home stack.
This is not a Hollywood fantasy. It is a foreseeable outcome of unmanaged complexity. As voice-enabled assistants, biometric locks, and behavioural analytics dashboards converge in our living rooms, they form a distributed surveillance grid.
