Researchers have disclosed a serious weakness in the WPA2 protocol that allows attackers within range of vulnerable device or access point to intercept passwords, e-mails, and other data presumed to be encrypted, and in some cases, to inject ransomware or other malicious content into a website a client is visiting.
The old showbiz adage continues to hold true (even in Wi-Fi testing): you can't please everyone. Shortly after our last round of mesh Wi-Fi testing, in which a six-pack of Plume devices surprised the field, e-mails arrived from both the Google Wifi and AmpliFi HD teams. The results weren't representative of their devices, they said, and perhaps I placed the devices badly. Both companies suggested placing an access point (AP) downstairs instead of all three APs being upstairs.
There's a new Wi-Fi standard in town, and it takes speed to another level. 802.11ad Wi-Fi is rated for data throughput up to 4,600Mbps, or four times faster than the current speed champ 802.11ac. That's much faster than standard gigabit Ethernet and most home broadband speeds, although—as any Wi-Fi user knows—there's a big difference between theoretical speed and what's possible in practice. Still, want to stream high-bitrate 4K, HDR films over Wi-Fi? That won't be a problem with 802.11ad. Even the best triple-layer UHD Blu-rays top out at 128Mbps bitrates.
Security researchers have devised a way of discovering passwords and other sensitive data by observing how bodily movements interfere with Wi-Fi signals.
The researchers from Shanghai Jaio Tong University, the University of Massachusetts at Boston, and the University of South Florida, found that they could find out private information by analysing the radio signal from a malicious Wi-Fi router.
Researchers in a team from Shanghai, Boston and Tampa recently published an temptingly titled paper about password stealing.
Dubbed When CSI Meets Public Wi-Fi: Inferring Your Mobile Phone Password via Wi-Fi Signals, the paper makes you think of Crime Scene Investigation, but that’s just a handy collision of acronyms.
