Don't Use Public Wi-Fi Without DNS Filtering
2022-01-18 06:55

Providing public Wi-Fi is a great service to offer your customers as it becomes more and more standard in today's society. According to recent statistics, there are about 410,000 public Wi-Fi hotspots in the United States alone, in public places such as parks, libraries, public transportation, and train stations.

Many users don’t know how to protect their broadband Wi-Fi routers

Millions of home broadband Wi-Fi routers in the UK could be at risk because many internet users do not take basic security precautions that could protect them from online threats, a research from Broadband Genie has found. In a survey of 1,320 broadband users, it was discovered that 88% have never updated their router firmware and 84% have never changed their router admin password.

Researchers Uncover New Coexistence Attacks On Wi-Fi and Bluetooth Chips
2021-12-16 19:40

Cybersecurity researchers have demonstrated a new attack technique that makes it possible to leverage a device's Bluetooth component to directly extract network passwords and manipulate traffic on a Wi-Fi chip. The novel attacks work against the so-called "Combo chips," which are specialized chips that are equipped to handle different types of radio wave-based wireless communications, such as Wi-Fi, Bluetooth, and LTE. "We provide empirical evidence that coexistence, i.e., the coordination of cross-technology wireless transmissions, is an unexplored attack surface," a group of researchers from the Technical University of Darmstadt's Secure Mobile Networking Lab and the University of Brescia said in a new paper.

Bugs in billions of WiFi, Bluetooth chips allow password, data theft
2021-12-13 16:04

Researchers at the University of Darmstadt, Brescia, CNIT, and the Secure Mobile Networking Lab, have published a paper that proves it's possible to extract passwords and manipulate traffic on a WiFi chip by targeting a device's Bluetooth component. To exploit these vulnerabilities, the researchers first needed to perform code execution on either the Bluetooth or WiFi chip.

Nine WiFi routers used by millions were vulnerable to 226 flaws
2021-12-02 14:30

Security researchers analyzed nine popular WiFi routers and found a total of 226 potential vulnerabilities in them, even when running the latest firmware. The tested routers are made by Asus, AVM, D-Link, Netgear, Edimax, TP-Link, Synology, and Linksys, and are used by millions of people.

UK Ministry of Justice secures HVAC systems 'protected' by passwordless Wi-Fi after Register tipoff
2021-11-23 10:15

The Ministry of Justice has secured a set of Wi-Fi access points that potentially gave admin access to industrial control equipment after a tipoff by The Register. Four unsecured wireless networks named "Boiler Pump 1" to "Boiler Pump 4" were freely accessible in the Royal Courts of Justice until The Register told officials what was happening.

Israeli Researcher Cracked Over 3,500 Wi-Fi Networks in Tel Aviv City
2021-10-28 20:52

Over 70% of Wi-Fi networks from a sample size of 5,000 were hacked with "Relative ease" in the Israeli city of Tel Aviv, highlighting how unsecure Wi-Fi passwords can become a gateway for serious threats to individuals, small businesses, and enterprises alike. CyberArk security researcher Ido Hoorvitch, who used a Wi-Fi sniffing equipment costing about $50 to collect 5,000 network hashes for the study, said "The process of sniffing Wi-Fis and the subsequent cracking procedures was a very accessible undertaking in terms of equipment, costs and execution."

War-Driving Technique Allows Wi-Fi Password-Cracking at Scale
2021-10-27 17:00

War-driving - the process of driving around mapping residential Wi-Fi networks in hopes of finding a vulnerability to exploit - can still pay off for attackers, apparently: A CyberArk researcher recently found he could easily slice open about 70 percent of Wi-Fi network passwords in one Tel Aviv community - all at once. After gathering what he felt was a decent sample size of 5,000 SSIDs and password hashes, it was then time to get crackin' - literally.

Researcher cracked 70% of WiFi networks sampled in Tel Aviv
2021-10-26 16:42

A researcher has managed to crack 70% of a 5,000 WiFi network sample in his hometown, Tel Aviv, to prove that home networks are severely unsecured and easy to hijack. CyberArk security researcher Ido Hoorvitch first wandered in the city center with WiFi sniffing equipment to gather a sample of 5,000 network hashes to use in the research.
