Mirai Botnet Variant Exploits Four-Faith Router Vulnerability for DDoS Attacks

Mirai Botnet Variant Exploits Four-Faith Router Vulnerability for DDoS Attacks

Jan 08, 2025 Malware / Vulnerability
A Mirai botnet variant has been found exploiting a newly disclosed security flaw impacting Four-Faith industrial routers since early November 2024 with the goal of conducting distributed denial-of-service (DDoS) attacks. The botnet maintains approximately 15,000 daily active IP addresses, with the infections primarily scattered across China, Iran, Russia, Turkey, and the United States. Exploiting an arsenal of over 20 known security vulnerabilities and weak Telnet credentials for initial access, the malware is known to have been active since February 2024. The botnet has been dubbed "gayfemboy" in reference to the offensive term present in the source code. QiAnXin XLab said it observed the malware leveraging a zero-day vulnerability in industrial routers manufactured by China-based Four-Faith to deliver the artifacts as early as November 9, 2024. The vulnerability in question is CVE-2024-12856 (CVSS score: 7.2), which refers to an operating system (OS) command injectio...
KmsdBot Malware Gets an Upgrade: Now Targets IoT Devices with Enhanced Capabilities

KmsdBot Malware Gets an Upgrade: Now Targets IoT Devices with Enhanced Capabilities

Aug 28, 2023 Internet of Things / Malware
An updated version of a botnet malware called  KmsdBot  is now targeting Internet of Things (IoT) devices, simultaneously branching out its capabilities and the attack surface. "The binary now includes support for  Telnet scanning  and support for more CPU architectures," Akamai security researcher Larry W. Cashdollar  said  in an analysis published this month. The latest iteration, observed since July 16, 2023, comes months after it emerged that the botnet is being offered as a  DDoS-for-hire service  to other threat actors. The fact that it's being actively maintained indicates its effectiveness in real-world attacks. KmsdBot was  first documented  by the web infrastructure and security company in November 2022. It's mainly employed to target private gaming servers and cloud hosting providers, although it has since set its eyes on some Romanian government and Spanish educational sites. The malware is designed to scan random IP ad...
What Is Attack Surface Management?

What Is Attack Surface Management?

Feb 03, 2025Attack Surface Management
Attack surfaces are growing faster than security teams can keep up – to stay ahead, you need to know what's exposed and where attackers are most likely to strike. With cloud adoption dramatically increasing the ease of exposing new systems and services to the internet, prioritizing threats and managing your attack surface from an attacker's perspective has never been more important. In this guide, we look at why attack surfaces are growing and how to monitor and manage them properly with  tools like Intruder . Let's dive in. What is your attack surface? First, it's important to understand what we mean when we talk about an attack surface. An attack surface is the sum of your digital assets that are 'reachable' by an attacker – whether they are secure or vulnerable, known or unknown, in active use or not. You can also have both internal and external attack surfaces - imagine for example a malicious email attachment landing in a colleague's inbox, vs a new FTP server being...
Warning! Seagate Wireless Hard Drives Have a Secret Backdoor for Hackers

Warning! Seagate Wireless Hard Drives Have a Secret Backdoor for Hackers

Sep 07, 2015
Several of Seagate's 3rd generation Wireless Hard drives have a secret backdoor for hackers that puts users' data at risk. A Recent study done by the security researchers at Tangible Security firm disclosed an " undocumented Telnet services " with a hard-coded password in Seagate Wireless Hard Drives. The secret Telnet Vulnerability ( CVE-2015-2874 ) with an inbuilt user account (default username and password — "root") allows an attacker to access the device remotely, left users data vulnerable to theft. According to US-CERT (Computer Emergency and Response Team) public advisory, multiple models of Seagate hard drives contain multiple vulnerabilities. Affected devices are: Seagate Wireless Plus Mobile Storage Seagate Wireless Mobile Storage (Wirelessly streaming your tablet and smartphone's data) LaCie FUEL (Wirelessly extending storage for iPads) The violation that an attacker can activate is, they can gain root access to the device and ac...

Backdoor found in Chinese Tenda Wireless Routers, allows Root access to Hackers

Backdoor found in Chinese Tenda Wireless Routers, allows Root access to Hackers

Oct 19, 2013
Last week Craig Heffner, specialized on the embedded device hacking exposed a serious backdoor in number of D-Link routers allows unauthorized backdoor access. Recently he published his another researcher, Titled ' From China, With Love ', exposed that D-Link is not only the vendor who puts backdoors in their products. According to him, China based networking device and equipment manufacturer - Tenda Technology  (www.tenda.cn) also added potential backdoors into their Wireless Routers. He unpacked the software framework update and locate the httpd binary an found that the manufacturer is using GoAhead server, which has been substantially modified. These routers are protected with standard Wi-Fi Protected Setup (WPS) and WPA encryption key, but still by sending a UDP packet with a special string , an attacker could take over the router. Routers contain a flaw in the httpd component, as the MfgThread() function spawns a b...
