Every year, thousands of people lose their lives in natural disasters. A major portion of deaths occur due to the lack of communication between survivors and first responders as communication channels including cell towers get erupted. Five young developers who competed against each other at computer hackathons joined forces and have developed a project named […]
While “Wi-Fi” has sorted us out with fast wireless internet connectivity, people have misconstrued the technology for having harmful health effects on users. However, a new study claims that it is a myth and suggests that Wi-Fi, in reality, is not bad for our health. According to a study by Kenneth R. Foster, professor emeritus of bioengineering […]
In late 2017, KRACK Attack crippled the popular 13-year-old WPA2 Wi-Fi standard used in our homes, offices, and public networks. The flaw allowed hackers to gain access to unencrypted traffic between the access point and the device — there were possibilities of breaking encryption as well. Months later, the Wi-Fi Alliance released the WPA3 protocol to bring improved wireless […]
Today, the world has become heavily reliant on computers owing to the various advantages they offer. It has thus become imperative that we, as users, remain updated about the various threats that can compromise the security of our data and privacy. A recent report published by Hackaday details a new threat that might just compromise […]
Crack WPA/WPA2 Wi-Fi Routers with Airodump-ng and Aircrack-ng/Hashcat. This is a brief walk-through tutorial that illustrates how to crack Wi-Fi networks that are secured using weak passwords. It is not exhaustive, but it should be enough information for you to test your own network’s security or break into one nearby. The attack outlined below is […]
A flight of new research papers show 4G LTE networks can be exploited for all sorts of badness. There have been lots of reasons to be concerned about how easily someone with the right tools and knowledge could do very bad things with cellular communications networks. And while none of them have necessarily been to […]
Many industrial networking devices from various vendors are still vulnerable to the recently disclosed KRACK attack (Key Reinstallation Attack). Many industrial networking devices are vulnerable to the recently disclosed KRACK attack (Key Reinstallation Attack), including products from major vendors such as Cisco, Rockwell Automation, and Sierra Wireless. A few weeks ago, researchers discovered several key management flaws in […]
We discovered serious weaknesses in WPA2, a protocol that secures all modern protected Wi-Fi networks. An attacker within range of a victim can exploit these weaknesses using key reinstallation attacks (KRACKs). Concretely, attackers can use this novel attack technique to read information that was previously assumed to be safely encrypted. This can be abused to steal sensitive information […]
Earlier this year we performed research into Broadcom’s Wi-Fi stack. Due to the ubiquity of Broadcom’s stack, we chose to conduct our prior research through the lens of one affected family of products — the Android ecosystem. To paint a more complete picture of the state of Wi-Fi security in the mobile ecosystem, we’ve chosen […]
Cyber security experts disclosed the existence of 10 unpatched security flaws in dozens of Linksys routers widely used today. The IOActive senior security consultant Tao Sauvage and the independent security researcher Antide Petit have reported more than a dozen of unpatched security vulnerabilities affecting 25 different Linksys Smart Wi-Fi Routers models. The security duo published […]
Short Bytes: The Linux kernel is the most used piece of software in the history of computing. It’s everywhere. It’s in computers, servers, phones, TVs, set-top boxes, submarines, airplanes, self-driving cars, and it even runs the International Space Station. But how does it work? That’s more than a mouthful, so I’ll try to break it up […]
Israeli hacker Amihai Neiderman needed three days to hack into Tel Aviv’s free public Wi-Fi. He only worked during the evenings, after he came home from his full-time job as a security researcher. The 26-year-old said the difficulty level was “a solid 5” on a scale from 1 to 10. The hack, performed in 2014 […]
Short Bytes: A group of researchers has revealed a new method to steal sensitive information from a user’s computer or phone. Named WindTalker, this technique sniffs a user’s hand movement on the screen and keyboard by reading the channel state information (CSI). To block this attack, the payment apps can simply randomize the keypad layouts. Every other […]
Just recently I stumbled upon an Android app that lets you receive free products in various pubs, restaurants or cafes in exchange for points accumulated with previous purchases. When the purchase is made, you let the vendor know that you want to receive points. In the app you select the types of products you bought. […]
Sławomir Jasek with research firm SecuRing is sounding an alarm over the growing number of Bluetooth devices used for keyless entry and mobile point-of-sales systems that are vulnerable to man-in-the-middle attacks. Jasek said the problem is traced back to devices that use the Bluetooth Low Energy (BLE) feature for access control. He said too often […]
When Wi-Fi was first developed in the late 1990s, Wired Equivalent Privacy was created to give wireless communications confidentiality. WEP, as it became known, proved terribly flawed and easily cracked. You can read more about that in my beginner’s guide to hacking Wi-Fi. As a replacement, most wireless access points now use Wi-Fi Protected Access […]
Security experts are warning owners of Mitsubishi Outlander Plug-In Hybrid Electric Vehicle that their cars can be hacked via the automobile’s on-board WiFi network used for remote control of key car features. The hybrid electronic vehicle, which is slated to be sold here in the U.S. starting this fall, suffers from weak password requirements that […]
Short Bytes: At the recently-held Moogfest, an art and music festival, artists Kyle McDonald and Surya Mattu showed how our devices continuously leak data that can be sniffed by anybody. Using an installation called Wi-Fi Whisperer, made from 8 Raspberry Pis and wireless antennas, they were able to grab such data and display in the form […]
OS X: NetSpot is a free utility that makes it easy to map out your wireless network, do a site survey if you have a particularly large one to manage, and to visualize where signal is strong and weak, and what might be getting in the way. We’ve mentioned NetSpot before, but the app has […]
Short Bytes: Facing problems with your broadband connection is a common headache that most people struggle with. The UK telecom regulator Ofcom has released a powerful app that tests your WiFi and gives you suggestions to improve your internet connection. The UK telecom watchdog Ofcom has launched a mobile app to find problems with your […]
Short bytes: There are different ways to retrieve the WiFi password of the network that you are connected to. Out of these, some methods include complex steps, whereas some are pretty handy and require only few commands to extract the WiFi password of your current network. Read the article to know how you can do […]
