Wireless

The vast majority of people out there don't know much about network security, if at all, but thankfully there are talented groups and individuals out there who are on constant lookout for flaws and vulnerabilities. Each security protocol we've seen has had some kind of issue (sometimes crippling), but the still-young Wi-Fi Protected Access protocol version 3, aka WPA3, remains vulnerable to attack, thanks to some pretty serious design flaws.

Thanks to upcoming developments in Wi-Fi, all of us connectivity-heads out there can look forward to getting familiar with new 802.11 protocols in the near future. Ars took a deep look at what's on the horizon last fall, but readers seemed to have a clear request in response—the time had come to specifically discuss the new Wi-Fi security protocol, WPA3.

It's one thing to report website vulnerabilities before they're used maliciously. It's another to blog about a vulnerability online.

Singapore authorities fined Zheng Dutao, an engineer at Chinese internet giant Tencent, S$5,000 (about $3,660) this week after discovering he hacked into a hotel's Wi-Fi system and shared sensitive information on his blog, ZDNet reported Tuesday.

The modern world is so hooked up to online services that when guests come around, “How ya doing?” will probably be followed by “What’s your Wi-Fi password?” But the hospitable host probably doesn’t realize that revealing this information could pose a network security risk.

For example, guests might accidentally download a malicious program or connect an already infected phone or laptop to the network. Many pieces of malware are able to spread themselves over a local network, and if an infected device is connected to your Wi-Fi, it will try to contaminate everything in its range.

You probably use Wi-Fi on the regular to connect your smartphone, computer, or other electronic device to the glory of the world wide web. But soon, that same technology could also keep you safe in real-life public areas.

According to a peer-reviewed study led by researchers from Rutgers University-New Brunswick, ordinary Wi-Fi can effectively and cheaply detect weapons, bombs, or explosive chemicals contained within bags.

It’s been a mildly rough week for Wi-Fi security: hard on the heels of a WPA2 weakness comes a programming cockup in the wpa_supplicant configuration tool used on Linux, Android, and other operating systems.

Looking for how to hack WiFi password OR WiFi hacking software?

Well, a security researcher has revealed a new WiFi hacking technique that makes it easier for hackers to crack WiFi passwords of most modern routers.

Accessing the internet isn't normally a problem when you're inside the confines of your own home—it's secure, it's easy to connect to, and it's relatively uncongested—unless the whole family is streaming Netflix on five separate devices. When you venture out though, it's a different story. You can access Wi-Fi in more places than ever, enabling you to keep in touch or catch up with work from wherever you happen to be, but getting online isn't quite as simple, or as safe, as it is with your home network.

Bluetooth has a bug which can allow hackers to slip in and steal data, even when you're in a secure connection.

The news was unveiled by Lior Neumann and Eli Biham, two cybersecurity researchers from the Israel Institute of Technology who discovered the vulnerability, known as CVE-2018-5383.

To present the problem in layman's terms, the pairing between two devices is weak due to a miscommunication, allowing remote attackers to obtain the encryption key used to secure a connection.

There is a moment of perfect stillness after the cable slips through my fingers and vanishes back up the hole in the ceiling like an angry snake. Then the opening stanza of a rich poem of invective leaps from my lips and my wife stares up at me from below, eyes wide, frozen just as I am, ready to catch me if I rage too hard and lose my balance.
