Zero-Day Remote 'Root' Exploit Disclosed In AT&T DirecTV WVB Devices

Zero-Day Remote 'Root' Exploit Disclosed In AT&T DirecTV WVB Devices

December 14, 2017Swati Khandelwal
Security researchers have publicly disclosed an unpatched zero-day vulnerability in the firmware of AT&T DirecTV WVB kit after trying to get the device manufacturer to patch this easy-to-exploit flaw over the past few months. The problem is with a core component of the Genie DVR system that's shipped free of cost with DirecTV and can be easily exploited by hackers to gain root access and take full control of the device, placing millions of people who've signed up to DirecTV service at risk. The vulnerability actually resides in WVBR0-25 —a Linux-powered wireless video bridge manufactured by Linksys that AT&T provides to its new customers. DirecTV Wireless Video Bridge WVBR0-25 allows the main Genie DVR to communicate over the air with customers' Genie client boxes (up to 8) that are plugged into their TVs around the home. Trend Micro researcher Ricky Lawshae, who is also a DirecTV customer, decided to take a closer look at the device and found that Linksy

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

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

Linksys Malware 'The Moon' Spreading from Router to Router

Which Wireless Router do you have at your Home or Office? If it's a Linksys Router you could be in the danger to a new malware that attacks your firmware and replicates itself. Security researcher Johannes B. Ullrich from the SANS Technology Institute has warned about a self-replicating malware which is exploiting authentication bypass and code-execution vulnerabilities in the Linksys wireless routers. The Malware named as ' THE MOON ', scans for other vulnerable devices to spread from router to router and Johannes confirmed that the malicious worm has already infected around 1,000 Linksys E1000, E1200, and E2400 routers. In order to hack the Router, malware remotely calls the Home Network Administration Protocol (HNAP), allows identification, configuration and management of networking devices. The Malware first request the model and firmware version of the router using HNAP and if the device founds vulnerable, it sends a CGI script exploit to get the local command execution
