Emotet Malware Now Hacks Nearby Wi-Fi Networks to Infect New Victims

Emotet Malware Now Hacks Nearby Wi-Fi Networks to Infect New Victims

February 12, 2020Ravie Lakshmanan
Emotet, the notorious trojan behind a number of botnet-driven spam campaigns and ransomware attacks, has found a new attack vector: using already infected devices to identify new victims that are connected to nearby Wi-Fi networks. According to researchers at Binary Defense , the newly discovered Emotet sample leverages a "Wi-Fi spreader" module to scan Wi-Fi networks, and then attempts to infect devices that are connected to them. The cybersecurity firm said the Wi-Fi spreader has a timestamp of April 16, 2018, indicating the spreading behavior has been running "unnoticed" for close to two years until it was detected for the first time last month. The development marks an escalation of Emotet's capabilities, as networks in close physical proximity to the original victim are now susceptible to infection. How Does Emotet's Wi-Fi Spreader Module Work? The updated version of the malware works by leveraging an already compromised host to list all
125 New Flaws Found in Routers and NAS Devices from Popular Brands

125 New Flaws Found in Routers and NAS Devices from Popular Brands

The world of connected consumer electronics, IoT, and smart devices is growing faster than ever with tens of billions of connected devices streaming and sharing data wirelessly over the Internet, but how secure is it? As we connect everything from coffee maker to front-door locks and cars to the Internet, we're creating more potential—and possibly more dangerous—ways for hackers to wreak havoc. Believe me, there are over 100 ways a hacker can ruin your life just by compromising your wireless router —a device that controls the traffic between your local network and the Internet, threatening the security and privacy of a wide range of wireless devices, from computers and phones to IP Cameras, smart TVs and connected appliances. In its latest study titled " SOHOpelessly Broken 2.0 ," Independent Security Evaluators (ISE) discovered a total of 125 different security vulnerabilities across 13 small office/home office (SOHO) routers and Network Attached Storage (NAS) de
WPA3 Standard Officially Launches With New Wi-Fi Security Features

WPA3 Standard Officially Launches With New Wi-Fi Security Features

June 26, 2018Swati Khandelwal
The Wi-Fi Alliance today officially launched WPA3 —the next-generation Wi-Fi security standard that promises to eliminate all the known security vulnerabilities and wireless attacks that are up today including the dangerous KRACK attacks . 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. However, in late last year, security researchers uncovered a severe flaw in the current WPA2 protocol, dubbed KRACK (Key Reinstallation Attack), that made it possible for attackers to intercept, decrypt and even manipulate WiFi network traffic. Although most device manufacturers patched their devices against KRACK attacks, the WiFi Alliance, without much delay, rushed to finalize and launch WPA3 in order to address WPA2's technical shortcomings from the ground.

The Wi-Fi Alliance has finally announced the long-awaited next generation of the wireless security protocol—Wi-Fi Protected Access (WPA3). WPA3 will replace the existing WPA2—the network security protocol that has been around for at least 15 years and widely used by billions of wireless devices every day, including smartphones, laptops and Internet of things. However, WPA2 has long been considered to be insecure due to its common security issue, that is " unencrypted " open Wi-Fi networks, which allows anyone on the same WiFi network to intercept connections on other devices. Most importantly, WPA2 has also recently been found vulnerable to KRACK (Key Reinstallation Attack) that makes it possible for attackers to intercept and decrypt Wi-Fi traffic passing between computers and access points. The new standard of Wi-Fi security, which will be available for both personal and enterprise wireless devices later this year, offers improved security and privacy. WPA3

KRACK Demo: Critical Key Reinstallation Attack Against Widely-Used WPA2 Wi-Fi Protocol

Do you think your wireless network is secure because you're using WPA2 encryption? If yes, think again! Security researchers have discovered several key management vulnerabilities in the core of Wi-Fi Protected Access II (WPA2) protocol that could allow an attacker to hack into your Wi-Fi network and eavesdrop on the Internet communications. WPA2 is a 13-year-old WiFi authentication scheme widely used to secure WiFi connections, but the standard has been compromised, impacting almost all Wi-Fi devices—including in our homes and businesses, along with the networking companies that build them. Dubbed KRACK — Key Reinstallation Attack —the proof-of-concept attack demonstrated by a team of researchers works against all modern protected Wi-Fi networks and can be abused to steal sensitive information like credit card numbers, passwords, chat messages, emails, and photos. Since the weaknesses reside in the Wi-Fi standard itself, and not in the implementations or any individua
Beware! Dozens of Linksys Wi-Fi Router Models Vulnerable to Multiple Flaws

Beware! Dozens of Linksys Wi-Fi Router Models Vulnerable to Multiple Flaws

April 20, 2017Swati Khandelwal
Bad news for consumers with Linksys routers: Cybersecurity researchers have disclosed the existence of nearly a dozen of unpatched security flaws in Linksys routers, affecting 25 different Linksys Smart Wi-Fi Routers models widely used today. IOActive's senior security consultant Tao Sauvage and independent security researcher Antide Petit published a blog post on Wednesday, revealing that they discovered 10 bugs late last year in 25 different Linksys router models. Out of 10 security issues (ranging from moderate to critical), six can be exploited remotely by unauthenticated attackers. According to the researchers, when exploited, the flaws could allow an attacker to overload the router, force a reboot by creating DoS conditions, deny legitimate user access, leak sensitive data, change restricted settings and even plant backdoors. Many of the active Linksys devices exposed on the internet scanned by Shodan were using default credentials, making them susceptible to the
