A security researcher has demonstrated that sensitive data could be exfiltrated from air-gapped computers via a novel technique that leverages Wi-Fi signals as a covert channel—surprisingly, without requiring the presence of Wi-Fi hardware on the targeted systems. Dubbed " AIR-FI ," the attack hinges on deploying a specially designed malware in a compromised system that exploits "DDR SDRAM buses to generate electromagnetic emissions in the 2.4 GHz Wi-Fi bands" and transmitting information atop these frequencies that can then be intercepted and decoded by nearby Wi-Fi capable devices such as smartphones, laptops, and IoT devices before sending the data to remote servers controlled by an attacker. The findings were published today in a paper titled "AIR-FI: Generating Covert Wi-Fi Signals from Air-Gapped Computers" by Dr. Mordechai Guri , the head of R&D at Ben-Gurion University of the Negev's Cyber-Security Research Center, Israel. "The AI...

Do you know what is the latest version of Wi-Fi? It's okay if you don't know. It is — Wi-Fi is 802.11ac. I am sure many of us can't answer this question immediately because the Wi-Fi technology doesn't have a traditional format of version numbers… at least until yesterday. The Wi-Fi Alliance—the group that manages the implementation of Wi-Fi—has today announced that the next version of WiFi standard, which is 802.11ax, will use a simpler naming scheme and will be called WiFi 6. Wi-Fi 6, based on the IEEE 802.11ax standard, will offer higher data rates, increased capacity, good performance—even in dense environments (such as stadiums or public venues) and improved power efficiency, making it perfect choice for smart home and IoT uses). Of course, the updated version names of all previous Wi-Fi standards will now be: 802.11b → Wi-Fi 1 802.11a → Wi-Fi 2 802.11g → Wi-Fi 3 802.11n → Wi-Fi 4, 802.11ac (current) → Wi-Fi 5 This new straightforward approach...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

Are you good at hiding your feelings? No issues, your Wi-Fi router may soon be able to tell how you feel, even if you have a good poker face. A team of researchers at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a device that can measure human inner emotional states using wireless signals. Dubbed EQ-Radio , the new device measures heartbeat, and breath to determine whether a person is happy, excited, sad, or angry. Using EQ-Radio, which emits and captures reflected radio frequency (RF) waves, the team bounced waves off a person's body to measure subtle changes in breathing patterns and heart rates. This data was then run through a bunch of algorithms and a machine-learning process programmed to match a person's behavior to how they acted previously, categorizing the person's emotion as one of the four emotional states: Pleasure, Joy, Anger and Sadness. The impressive part about the technique: EQ-Radio doesn't r...

Microsoft has finally decided to remove one of its controversial features  Wi-Fi Sense network sharing feature from Windows 10 that shares your WiFi password with your Facebook, Skype and Outlook friends and enabled by default. With the launch of Windows 10 last year, Microsoft introduced Wi-Fi Sense network sharing feature aimed at making it easy to share your password-protected WiFi network with your contacts within range, eliminating the hassle of manually logging in when they visit. This WiFi password-sharing option immediately stirred up concerns from Windows 10 users especially those who thought the feature automatically shared your WiFi network with all your contacts who wanted access. Must Read: Here's How to run Ubuntu Linux on Windows 10 . But Wi-Fi Sense actually hands over its users controls so they can select which networks to share and which contact list can access their Wi-Fi. Also, the feature doesn't share the actual password used to protect yo...

A researcher has demonstrated how easy it is to steal high-end drones, commonly deployed by government agencies and police forces, from 2 kilometres away with the help of less than $40 worth of hardware . The attack was developed by IBM security researcher Nils Rodday, who recently presented his findings at Black Hat Asia 2016. Hacking the $28,463 Drone with Less than $40 of Hardware Rodday explained how security vulnerabilities in a drone's radio connection could leverage an attacker ( with some basic knowledge of radio communications ) to hijack the US$28,463 quadcopters with less than $40 of hardware. Rodday discovered ( PPT ) two security flaws in the tested drone that gave him the ability to hack the device in seconds. First, the connection between drone's controller module, known as telemetry box, and a user's tablet uses extremely vulnerable ' WEP ' ( Wired-Equivalent Privacy ) encryption – a protocol long known to be 'crackable in sec...

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...

Security researchers have uncovered a zero-day vulnerability in iOS 8 that could repeatedly crash users' Apple iPhones, iPads and iPods when the devices connect to a malicious wireless hotspot. It's like Denial of Service (DoS) attack on Apple's iOS devices that results in crashing either individual iOS apps or users' entire iPhones. NO iOS ZONE Adi Sharabani and Yair Amit of Mobile security firm Skycure presented their latest research, titled " No iOS Zone ", at the RSA security conference in San Francisco on Tuesday. The duo showed: It is possible for an attacker to create malicious Wi-Fi networks in order to crash nearby users' mobile devices with incredible accuracy. Also, even the "No iOS Zone" attack is capable to make iOS things within the range completely unusable by triggering constant numbers of reboots. It is nothing but a DoS attack… ...that makes the device inaccessible by its users, just like in the ca...

A Greek security researcher, named George Chatzisofroniou , has developed a WiFi social engineering tool that is designed to steal credentials from users of secure Wi-Fi networks. The tool, dubbed WiFiPhisher , has been released on the software development website GitHub on Sunday and is freely available for users. "It's a social engineering attack that does not use brute forcing in contrast to other methods. It's an easy way to get WPA passwords ," said George Chatzisofroniou. However, there are several hacking tools available on the Internet that can hack a secure Wi-Fi network, but this tool automates multiple Wi-Fi hacking techniques which make it slightly different from others. WiFiPhisher tool uses "Evil Twin" attack scenario. Same as Evil Twin, the tool first creates a phony wireless Access Point (AP) masquerade itself as the legitimate Wi-Fi AP. It then directs a denial of service (DoS) attack against the legitimate Wi-Fi access poi...

Security researchers have discovered a new type of "Man-in-the-Middle" (MitM) attack in the wild targeting smartphone and tablets users on devices running either iOS or Android around the world. The MitM attack, dubbed DoubleDirect , enables an attacker to redirect a victim's traffic of major websites such as Google, Facebook and Twitter to a device controlled by the attacker. Once done, cyber crooks can steal victims' valuable personal data, such as email IDs, login credentials and banking information as well as can deliver malware to the targeted mobile device. San Francisco-based mobile security firm Zimperium detailed the threat in a Thursday blog post , revealing that the DoubleDirect technique is being used by attackers in the wild in attacks against the users of web giants including Google, Facebook, Hotmail, Live.com and Twitter, across 31 countries, including the U.S., the U.K. and Canada. DoubleDirect makes use of ICMP (Internet Control Message P...

A seven-year-old cyber espionage campaign has targeted senior level executives from large global companies by using a specialized Advanced Persistent Threat (APT) , zero-day exploits, and well-developed keyloggers to extract information from them when they stay in luxury hotels during their business trips. The researchers at Moscow-based security firm Kaspersky Lab dubbed the threat as " DarkHotel APT ," appear to have the ability to know in advance when a targeted executive checks in and checks out of a hotel. The group has been operating in Asia since from 2009 but there have been infections recorded in the United States, South Korea, Singapore, Germany, Ireland and many others, as well. It uses hotel Wi-Fi networks to target elite executives at organisations in manufacturing, defense, investment capital, private equity, automotive and other industries. The group has access to zero day vulnerabilities and exploits, and it used them to infect victims. Threa...

Almost a year ago, at the ' Hack In The Box ' security summit in Amsterdam, a security researcher at N.Runs and a commercial airline pilot, Hugo Teso presented a demonstration that it's possible to take control of aircraft flight systems and communications using an Android smartphone and some specialized attack code. Quite similar to the previous one, a security researcher claims to have devised a method that can give cyber criminals access to the satellite communications equipment on passenger jets through their WiFi and in-flight entertainment systems. Cyber security expert Ruben Santamarta, a consultant with cyber security firm IOActive , will unveil his research and all the technical details this week at a major Las Vegas hacker convention, Black Hat conference, showing How commercial airliner satellite communication systems can also be compromised by hackers, along with the evidence of satellite communications system vulnerabilities that questions the standards th...

A leading provider of advanced threat, security and compliance solutions, Tripwire , has announced that Craig Young , a security researcher from its Vulnerability and Exposure Research Team (VERT) , is working on a paper about SSL vulnerabilities that will be presented at DEF CON 22 Wireless Village . There are thousands of websites over Internet that contain serious mistakes in the way that Secure Sockets Layer and Transport Layer Security (SSL/TLS) is implemented, leaving them vulnerable to man-in-the-middle (MitM) attacks that could compromise sensitive user data such as banking credentials, credit card numbers and other information. MitM attack is one of the common and favorite techniques of attackers used to intercept wireless data traffic. Cyber criminals could able to intercept sensitive user data, including credit card numbers, PayPal credentials and social network credentials as well. Young has unearthed various situations where poor SSL implementations in co...

Until now, we have seen how different smart home appliances such as refrigerators, TVs and routers could expose our private data, but now you can add another worry to your list —LED light bulb. Don't laugh! It's true. Researchers at UK security firm Context have formulated an attack against the Wi-Fi connected lightbulbs, which is available to buy in the UK, that exposes credentials of the Wi-Fi network, it relies on to operate, to anyone in accessibility to one of the LED devices. Security vulnerabilities found in the LIFX Smart light bulbs , that can be controlled by the iOS-based and Android-based devices, could allow an attacker to gain access to a "master bulb" and with the help of that they could control all connected bulbs across that network, and help them expose user network configurations. Along with other Internet of Things (IoTs) devices, the smart bulbs are part of a rising trend in which the manufacturers enclose computing and networking capabilities to their devices s...

Do you own a blog on WordPress.com website? If Yes, then you should take some extra cautious while signing into your Wordpress account from the next time when connected to public Wi-Fi, because it can be hacked without your knowledge, even if you have enabled two-factor authentication. Yan Zhu , a researcher at the Electronic Frontier Foundation (EFF) noticed that the blogs hosted on WordPress are sending user authentication cookies in plain text, rather than encrypting it. So, it can be easily hijacked by even a Script-Kiddie looking to steal information. HIJACKING  AUTHENTICATION COOKIES When Wordpress users log into their account, WordPress.com servers set a web cookie with name " wordpress_logged_in " into the users' browser, Yan Zhu explained in a blog post. He noticed that this authentication cookie being sent over clear HTTP, in a very insecure manner. One can grab HTTP cookies from the same Wi-Fi Network by using some specialized tools, such as F...
