Realtek Vulnerability Under Attack: Over 134 Million Attempts to Hack IoT Devices

Realtek Vulnerability Under Attack: Over 134 Million Attempts to Hack IoT Devices

Jan 30, 2023 Internet of Things / Malware
Researchers are warning about a spike in exploitation attempts weaponizing a now-patched critical remote code execution flaw in Realtek Jungle SDK since the start of August 2022. According to Palo Alto Networks Unit 42, the ongoing campaign is said to have recorded 134 million exploit attempts as of December 2022, with 97% of the attacks occurring in the past four months. Close to 50% of the attacks originated from the U.S. (48.3%), followed by Vietnam (17.8%), Russia (14.6%), The Netherlands (7.4%), France (6.4%), Germany (2.3%0, and Luxembourg (1.6%). What's more, 95% of the attacks leveraging the security shortcoming that emanated from Russia singled out organizations in Australia. "Many of the attacks we observed tried to deliver malware to infect vulnerable IoT devices," Unit 42 researchers  said  in a report, adding "threat groups are using this vulnerability to carry out large-scale attacks on smart devices around the world."

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

Aug 17, 2021
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
Timing is Everything: The Role of Just-in-Time Privileged Access in Security Evolution

Timing is Everything: The Role of Just-in-Time Privileged Access in Security Evolution

Apr 15, 2024Active Directory / Attack Surface
To minimize the risk of privilege misuse, a trend in the privileged access management (PAM) solution market involves implementing just-in-time (JIT) privileged access. This approach to  privileged identity management  aims to mitigate the risks associated with prolonged high-level access by granting privileges temporarily and only when necessary, rather than providing users with continuous high-level privileges. By adopting this strategy, organizations can enhance security, minimize the window of opportunity for potential attackers and ensure that users access privileged resources only when necessary.  What is JIT and why is it important?   JIT privileged access provisioning  involves granting privileged access to users on a temporary basis, aligning with the concept of least privilege. This principle provides users with only the minimum level of access required to perform their tasks, and only for the amount of time required to do so. One of the key advantages of JIT provisioning

Researchers Warn of Critical Bugs Affecting Realtek Wi-Fi Module

Jun 03, 2021
A new set of critical vulnerabilities has been disclosed in the Realtek RTL8170C Wi-Fi module that an adversary could abuse to gain elevated privileges on a device and hijack wireless communications. "Successful exploitation would lead to complete control of the Wi-Fi module and potential root access on the OS (such as Linux or Android) of the embedded device that uses this module," researchers from Israeli IoT security firm Vdoo  said  in a write-up published yesterday. The Realtek  RTL8710C  Wi-Fi SoC underpins Ameba, an Arduino-compatible programmable platform equipped with peripheral interfaces for building a variety of IoT applications by devices spanning across agriculture, automotive, energy, healthcare, industrial, security, and smart home sectors. The flaws affect all embedded and IoT devices that use the component to connect to Wi-Fi networks and would require an attacker to be on the same Wi-Fi network as the devices that use the RTL8710C module or know the ne
