Lumos System Can Find Hidden Cameras and IoT Devices in Your Airbnb or Hotel Room

Lumos System Can Find Hidden Cameras and IoT Devices in Your Airbnb or Hotel Room
May 25, 2022Ravie Lakshmanan
A group of academics has devised a system that can be used on a phone or a laptop to identify and locate Wi-Fi-connected hidden IoT devices in unfamiliar physical spaces. With hidden cameras being  increasingly   used  to  snoop  on  individuals  in hotel rooms and Airbnbs, the goal is to be able to pinpoint such rogue devices without much of a hassle. The system, dubbed Lumos , is designed with this intent in mind and to "visualize their presence using an augmented reality interface,"  said  Rahul Anand Sharma, Elahe Soltanaghaei, Anthony Rowe, and Vyas Sekar of Carnegie Mellon University in a new paper. At its core, the platform works by snuffing and collecting encrypted wireless packets over the air to detect and identify concealed devices. Subsequently, it estimates the location of each identified device with respect to the user as they walk around the perimeter of the space. The localization module, for its part, combines signal strength measurements that are avail

Multiple Flaws Affecting Realtek Wi-Fi SDKs Impact Nearly a Million IoT Devices

Multiple Flaws Affecting Realtek Wi-Fi SDKs Impact Nearly a Million IoT Devices

Taiwanese chip designer Realtek is warning of  four security vulnerabilities  in three software development kits (SDKs) accompanying its WiFi modules, which are used in almost 200 IoT devices made by at least 65 vendors. The flaws, which affect Realtek SDK v2.x, Realtek "Jungle" SDK v3.0/v3.1/v3.2/v3.4.x/v3.4T/v3.4T-CT, and Realtek "Luna" SDK up to version 1.3.2, could be abused by attackers to fully compromise the target device and execute arbitrary code with the highest level of privilege — CVE-2021-35392  (CVSS score: 8.1) - Heap buffer overflow vulnerability in 'WiFi Simple Config' server due to unsafe crafting of SSDP NOTIFY messages CVE-2021-35393  (CVSS score: 8.1) - Stack buffer overflow vulnerability in 'WiFi Simple Config' server due to unsafe parsing of the UPnP SUBSCRIBE/UNSUBSCRIBE Callback header CVE-2021-35394  (CVSS score: 9.8) - Multiple buffer overflow vulnerabilities and an arbitrary command injection vulnerability in 'UD

ALERT! Hackers targeting IoT devices with a new P2P botnet malware

ALERT! Hackers targeting IoT devices with a new P2P botnet malware

Cybersecurity researchers have taken the wraps off a new botnet hijacking Internet-connected smart devices in the wild to perform nefarious tasks, mostly DDoS attacks, and illicit cryptocurrency coin mining. Discovered by Qihoo 360's Netlab security team, the  HEH Botnet  — written in Go language and armed with a proprietary peer-to-peer (P2P) protocol, spreads via a brute-force attack of the Telnet service on ports 23/2323 and can execute arbitrary shell commands. The researchers said the HEH botnet samples discovered so far support a wide variety of CPU architectures, including x86(32/64), ARM(32/64), MIPS(MIPS32/MIPS-III), and PowerPC (PPC). The botnet, despite being in its early stages of development, comes with three functional modules: a propagation module, a local HTTP service module, and a P2P module. Initially downloaded and executed by a malicious Shell script named "wpqnbw.txt," the HEH sample then uses the Shell script to download rogue programs for all
