Black Duck Researchers Discover Flaw in Widely Used Broadcom ChipsetA flaw in Broadcom chipsets commonly used in wireless routers allows attackers to repeatedly knock offline the 5 gigahertz band, no matter how strong the security settings, say researchers.
Pedestrians Uniquely Refract Directional Radio SignalsThe way you use your walk - specifically when striding through a Wi-Fi field shaped by directional antennae - can reveal who you are, found researchers who investigated the surveillance potential of wireless routers. "Every router is a potential surveillance device," say researchers.
Security Researchers Reveal Methods to Reverse Engineer MediaTek FirmwareReverse engineering Wi-Fi chips opens new opportunities for security research. Security researchers Daniel Wegemer and Edoardo Mantovani describe tools, methods and motivations for unlocking hidden functions and enabling deeper hardware analysis.
Researchers in Proof of Concept Show Exploit Potential for Widely Used SoftwareTechnical details for a recently patched maximum-severity vulnerability in Cisco IOS XE reveal how hackers can enable remote code execution if the flaw is exploited. The vulnerability is an arbitrary file upload triggered by a hardcoded JSON Web Token.
Researchers Uncover Bugs in Apple’s AirPlay, Risking Takeover of Smart DevicesVulnerabilities in wireless streaming protocol AirPlay could expose Apple operating system devices to remote code execution by enabling attackers to infiltrate networks through trusted connections. The flaws are in the software development kit used by third-party manufacturers.
Cybersecurity Firm Warns of 'Hidden Features' in the Widely Used ESP32 ChipResearchers have discovered 29 undocumented commands in the Bluetooth implementation of the ESP32 microcontroller - one of the world's most widely used chips in internet of things devices and industrial IoT devices - that attackers could use to read and modify device memory.
Researchers Discover 20 Critical Flaws Attackers Could Exploit in a Variety of WaysResearchers identified 20 critical vulnerabilities in a type of Advantech industrial-grade wireless access point that's widely deployed across critical infrastructure environments. Attackers could exploit the flaws to remotely executive code and create denials of service.
'Nearest Neighbor Attack' Bypasses Cyber Defenses by Breaching WiFi NetworksA Russian cyberespionage group hacked a Washington, D.C.-based organization focused on Ukraine by deploying a new attack technique that exploits Wi-Fi connectivity, according to new research. The "nearest neighbor attack: methodology could lead to a significant broadening of targeting and attacks.
VPN Endpoints, Wireless Routers and Network-Attached Storage Devices Are TargetsOperators behind a mysterious botnet named for a TCP routing port number are expanding the universe of targeted devices and taking steps to hide their infrastructure, warn Sekoia researchers. The 7777 - or Quad7 - botnet appears to have emerged in 2023.
Wireless Gear Shifting System Is Vulnerable to Replay AttacksImagine cruising down a bike path and having the gears suddenly shift without warning. Security researchers say cybercriminals could take advantage of new wireless controlled bicycle gear systems to make that happen - and cause crashes and injuries.
Starlink Routers in Ukraine and Gaza Trackable via Apple WPS, Researchers WarnApple's Wi-Fi-based positioning system can be abused to track the live location of various types of devices around the globe, including Starlink routers in war zones, researchers warn. Until Apple puts in place more defenses, they say the system will continue to pose a "large-scale privacy threat."
