Scan of 16 million home networks worldwide uncovers new vulnerabilities in smart homes across the globe
- Printers are the most vulnerable home devices in Australia
- 33.4 percent of connected homes in Australia have one or more vulnerable device
- 59.7 percent of household routers worldwide are vulnerable
The report illustrates that just one connected device can compromise the security of the whole home network.
“People use their smart TV to watch their favourite Netflix series or connect their baby monitor to their home network. However, often they don’t know how to maintain the security of that device,” said Ondrej Vlcek, President, Consumer at Avast.
“It only takes one weak device to let in a bad hacker and once they are on the network, they can access other devices and the personal data they stream or store, including live videos and voice recordings. Simple security steps will significantly improve the integrity of digital homes. For example, the setting of strong, unique passwords and two-factor authentication for all device access, and ensuring software patches and firmware updates are applied when available.”
Weak credentials and out of date software
The majority (69.2%) of vulnerable devices in households worldwide (55.4% in Australia) were discovered to be vulnerable due to having weak credentials, such as simple passwords or the use of one-factor authentication. A further 31.8 percent of these devices worldwide (45.1% in Australia) were vulnerable due to not being patched.
Avast also scanned 11 million routers worldwide and found that over half (59.7%) worldwide either have weak credentials or software vulnerabilities. Out-of-date software is often the weakest link in the security chain, making it an easy gateway for cybercriminals looking to access other connected devices.
The most vulnerable devices
Based on a scan of 117,773 Australian home networks, the research found that the top seven most vulnerable devices in Australia were:
- Printers 35.8%
- Network nodes 19.7%
- NAS 19.4%
- Security cameras 11%
- Media boxes 8.5%
- TVs 3.2%
- Gaming consoles 0.5%

The data in this document has been obtained from scans run by Avast users from their computers, using the Avast Wi-Fi Inspector during September 2018. In total, 16 million different home networks worldwide are included in this study, from countries all around the world. 56 million individual devices were scanned. The report focuses on the emerging connected devices, as opposed to computers and smartphones.
