While using your cell phone at a massive public event, like a concert, conference, or sporting event, you have probably experienced slow communication, poor performance or slow browsing speeds, as crowds arrive. That's because of ' Spectrum Crunch ', which means, Interference of WiFi signals with each other. WiFi signals of all cell-phones in a large event interfere with each other because they are all fighting over the same limited spectrum but there is not enough bandwidth to handle all the traffic from the cellphones that are trying to use the same frequency slice at the same time, leaving them frustrated with painfully slow Internet access. However, a team of researchers from the MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) has developed a solution for this problem. In a new research paper, 'Real-time Distributed MIMO Systems,' published online this week, the MIT team described a system for managing networks that cause the WiFi ...

Apple has patched a critical vulnerability in its iOS operating system that allowed criminal hackers to impersonate end users' identities by granting read/write access to website's unencrypted authentication cookies. The vulnerability was fixed with the release of iOS 9.2.1 on Tuesday, almost three years after it was first discovered and reported to Apple. The vulnerability, dubbed " Captive Portal " bug, was initially discovered by Adi Sharabani and Yair Amit from online security company Skycure and privately reported to Apple in June 2013. Here's How the Vulnerability Worked The vulnerability caused due to the way iOS handles Cookie Stores at Captive Portals , generally a login page that requires users to authenticate themselves before connecting to the free or paid public Wi-Fi hotspots when they are first joining. So, when a user with a vulnerable iPhone or iPad connects to a captive-enabled network ( sample page shown in the screensho...

In today's rapidly evolving threat landscape, safeguarding your organization against cyberattacks is more critical than ever. Traditional penetration testing (pentesting), while effective, often falls short due to its high costs, resource requirements, and infrequent implementation. Automated internal and external network pentesting is a game-changing solution, empowering organizations to stay ahead of attackers with cost-effective, frequent, and thorough security assessments. Strengthen Your Defenses: The Role of Internal and External Pentests  Effective cybersecurity requires addressing threats from both inside and outside your organization. Automated solutions streamline this process, enabling IT teams to implement a holistic and proactive defense strategy. Internal Pentesting: Securing the Core Internal pentesting simulates an attacker operating within your network, exposing vulnerabilities such as insider threats, compromised credentials, or breaches through physical or ...

It is a common problem: Home Wireless Router's reach is terrible that the WiFi network even does not extend past the front door of the room. My house also has all kinds of Wi-Fi dead zones, but can we fix it? The answer is: YES . The problem will improve with a future, longer range version of Wi-Fi that uses low power consumption than current wireless technology and specifically targets at the internet of things (IoTs). Global certification network the WiFi Alliance has finally approved a new wireless technology standard called 802.11ah, nicknamed " HaLow ." HaLow: Long Range WiFi Wi-Fi HaLow has twice the range of conventional Wi-Fi and has the ability to penetrate walls that usually create blackspots in our homes. The Wi-Fi Alliance unveiled this latest WiFi technology at the Consumer Electronics Show (CES) in Las Vegas. Although currently used 802.11 Wi-Fi standards commonly operate in frequency bandwidths between 2.4GHz and 5GHz, the n...

Just one day after Microsoft released its new operating system, over 14 Million Windows users  upgraded their PCs to Windows 10 . Of course, if you are one of the Millions, you should aware of Windows 10's Wi-Fi Sense feature that lets your friends automatically connects to your wireless network without providing the Wi-Fi password. Smells like a horrible Security Risk! It even triggered a firestorm among some security experts, who warned that Wi-Fi Sense is a terrible and dangerous feature and that you should disable it right away. Even some researchers advised Windows 10 users to rename their Wi-Fi access points. Before discussing the risks of Wi-Fi Sense, let's first know how it works. Also Read:  How to Fix 35+ Windows 10 Privacy Issues With Just One Click . How Windows 10 Wi-Fi Sense works? Windows 10 Wi-Fi Sense feature allows you to share your Wi-Fi password with your friends or contacts, as well as lets you automatically connect to netwo...

There is no end to users problem when it comes to security. Everything is easily hackable — from home wireless routers to the large web servers that leak users' personal data into the world in one shot. If you love to travel and move hotels to hotels, then you might be dependent on free Wi-Fi network to access the Internet. However, next time you need to be extra cautious before connecting to Hotel's Wi-Fi network, as it may expose you to hackers. Security researchers have unearthed a critical flaw in routers that many hotel chains depend on for distributing Wi-Fi networks. The security vulnerability could allow a hacker to infect guests with malware, steal or monitor personal data sent over the network, and even gain access to the hotel's keycard systems and reservation. HACKING GUEST WIFI ROUTER Several models of InnGate routers manufactured by ANTlabs, a Singapore firm, have a security weakness in the authentication mechanism of the firmware. The se...
