A set of 38 security vulnerabilities has been uncovered in wireless industrial internet of things (IIoT) devices from four different vendors that could pose a significant attack surface for threat actors looking to exploit operational technology (OT) environments. "Threat actors can exploit vulnerabilities in Wireless IIoT devices to gain initial access to internal OT networks," Israeli industrial cybersecurity company Otorio  said . "They can use these vulnerabilities to bypass security layers and infiltrate target networks, putting critical infrastructure at risk or interrupting manufacturing." The flaws, in a nutshell, offer a remote entry point for attack, enabling unauthenticated adversaries to gain a foothold and subsequently use it as leverage to spread to other hosts, thereby causing serious damage. Some of the identified shortcomings could be chained to give an external actor direct access to thousands of internal OT networks over the internet, security

The company stressed that the issue only affects the following products if running Cisco WLC Software Release 8.10.151.

The need for vCISO services is growing. SMBs and SMEs are dealing with more third-party risks, tightening regulatory demands and stringent cyber insurance requirements than ever before. However, they often lack the resources and expertise to hire an in-house security executive team. By outsourcing security and compliance leadership to a vCISO, these organizations can more easily obtain cybersecurity expertise specialized for their industry and strengthen their cybersecurity posture. MSPs and MSSPs looking to meet this growing vCISO demand are often faced with the same challenge. The demand for cybersecurity talent far exceeds the supply. This has led to a competitive market where the costs of hiring and retaining skilled professionals can be prohibitive for MSSPs/MSPs as well. The need to maintain expertise of both security and compliance further exacerbates this challenge. Cynomi, the first AI-driven vCISO platform , can help. Cynomi enables you - MSPs, MSSPs and consulting firms

The same team of cybersecurity researchers who discovered several severe vulnerabilities, collectively dubbed as Dragonblood , in the newly launched WPA3 WiFi security standard few months ago has now uncovered two more flaws that could allow attackers to hack WiFi passwords . WPA, or WiFi Protected Access, is a WiFi security standard that has been designed to authenticate wireless devices using the Advanced Encryption Standard (AES) protocol and intended to prevent hackers from eavesdropping on your wireless data. The WiFi Protected Access III (WPA3) protocol was launched a year ago in an attempt to address technical shortcomings of the WPA2 protocol from the ground, which has long been considered to be insecure and found vulnerable to more severe KRACK attacks . WPA3 relies on a more secure handshake, called SAE (Simultaneous Authentication of Equals), which is also known as Dragonfly, that aims to protect WiFi networks against offline dictionary attacks. However, in less

🔥 Breaking — It has been close to just one year since the launch of next-generation Wi-Fi security standard WPA3 and researchers have unveiled several serious vulnerabilities in the wireless security protocol that could allow attackers to recover the password of the Wi-Fi network. WPA, or Wi-Fi Protected Access, is a standard designed to authenticate wireless devices using the Advanced Encryption Standard (AES) protocol and is intended to prevent hackers from eavesdropping on your wireless data. The Wi-Fi Protected Access III (WPA3) protocol was launched in an attempt to address technical shortcomings of the WPA2 protocol from the ground, which has long been considered to be insecure and found vulnerable to KRACK (Key Reinstallation Attack). Though WPA3 relies on a more secure handshake, known as Dragonfly , that aims to protect Wi-Fi networks against offline dictionary attacks, security researchers Mathy Vanhoef and Eyal Ronen found weaknesses in the early implementation

Yes, it's time to shift from Wi-Fi to Li-Fi — an alternative technology that is 100 times faster than the average speeds of Wi-Fi . Scientists have just field-tested the new wireless technology called Li-Fi for the first time and achieved marvelous wireless speeds that are 100 times faster than current WiFi speeds. What is Li-Fi Technology? Li-Fi is a new wireless technology that transmits high-speed data using light (i.e. Visible Light Communication or VLC) rather than radio bands. In short, Li-Fi is a Super-Fast alternative to Wi-Fi. Earlier this year, scientists achieved mind-blowing speeds of 224 gigabits per second (Gbps) in the lab using Li-Fi. It's believed that this technology has the potential to change everything about the way we use the Internet today. And Yes, it will. Test Results: Li-Fi is 100 times Faster than Wi-Fi An Estonian startup company called Velmenni took the technology out of the laboratories and into the real-

Forget about Superman's X-rays vision, you can now see through walls using WI-FI device only. Scientists at MIT's Computer Science and Artificial Intelligence Lab ( CSAIL ) have developed a device that uses WiFi signals to effectively see through walls and other obstacles, and identify which persons are standing behind it. Dubbed RF Capture , the new system is enhanced version of their previous methods of capturing movements across a house – technology used by mothers to see their baby's breathing and firefighters to determine if there are survivors in a burning building. How Does RF Capture Work? The working of RF Capture is actually quite simple and relatively straightforward. RF-Capture works by transmitting wireless signals that, upon hitting a person standing behind a wall, are reflected off various body parts and then back to the device for analysis to piece together the whole image of people. RF-Capture transmits radio waves that pass thro

Security researchers from Core Security has reportedly found a Denial of Service ( DoS ) attack vulnerability in Android WiFi-Direct. Android's WiFi-Direct is a wireless technology that allows two devices to establish a direct, peer-to-peer Wi-Fi connection without requiring a wireless router. Smartphones have been able to support Wi-Fi Direct for a while now. According to the advisory , the remotely exploitable denial-of-service vulnerability is affecting a wide number of Android mobile devices when it scans for WiFi Direct devices. If exploited, the vulnerability would let an attacker force a reboot of a device. " An attacker could send a specially crafted 802.11 Probe Response frame causing the Dalvik subsystem to reboot because of an Unhandle Exception on WiFiMonitor class ," advisory states. The Android WiFi-Direct vulnerability (CVE-2014-0997) affects: Nexus 5 - Android 4.4.4 Nexus 4 - Android 4.4.4 LG D806 - Android 4.2.2 Samsung SM-T310 - Android

Multiple Cisco Wireless Residential Gateway products have a security vulnerability in the web server that could allow a remote attacker to hijack the devices remotely. Cisco announced that a number of its Wireless Residential Gateway products are vulnerable to a remote-code execution attack , which is exploited by sending a specially crafted HTTP request to the web server running on the affected device. According to Cisco, the flaw is due to the incorrect input validation for HTTP requests, which could allow an attacker to exploit a buffer overflow and run arbitrary code on the device. The bug is about as serious as they come, giving remote, unauthenticated attackers access to the affected machines. " Successful exploitation of the vulnerability may cause the embedded web server to crash and allow the attacker to inject arbitrary commands and execute arbitrary code with elevated privileges, " the Cisco advisory says, and until now, " There are currently no known workarou

In this era of mass surveillance, we have always learned from security folks to protect and encrypt our communication and networks, especially widely open private Wi-Fi networks. It is always recommended to use a strong password and encryption on Wireless Routers in an effort to safeguard the privacy and security of our web communication and personal data. Quite the contrary, a group of activists says opening up your home Wi-Fi network could not only enhance your privacy, but actually increase it in the process. A new movement dubbed as " Open Wireless Movement " is encouraging the users to open-up their private network or at least a small portion of the available bandwidth to strangers. It really sounds quite annoying! Isn't it? In this case any unknown can consume a large part of your network bandwidth or can use your network to perform illicit activities, and it will come as a great boon for those cyber thieves who are in wake of finding such open networks to carr

Do you know, A Computer viruses could go Airborne over WiFi networks? Security researchers at the University of Liverpool  in Britain have demonstrated a WiFi virus that can spread between computer networks just like the ' common cold ' spreads between Humans. They have created a proof-of-concept which can infect the entire wireless network instead of a single computer at a time,  that replaces the firmware of the vulnerable Access Point (AP) with a virus-loaded version, and then propagates itself to the next victim on the WiFi network . The  WiFi  based virus named as ' Chameleon ', that can self-propagate over WiFi networks from access point to access point,  but  doesn't affect the working of the Wireless Access Point. This Virus is able to identify WiFi access points that are not protected by encryption and passwords, according to the research paper . It can badly hit less-protected open access WiFi networks available in coffee shops or airp
