Remote Root | Breaking Cybersecurity News | The Hacker News

Security researchers have discovered several severe vulnerabilities and a secret hard-coded backdoor in Western Digital's My Cloud NAS devices that could allow remote attackers to gain unrestricted root access to the device. Western Digital's My Cloud (WDMyCloud) is one of the most popular network-attached storage devices which is being used by individuals and businesses to host their files, and automatically backup and sync them with various cloud and web-based services. The device lets users not only share files in a home network, but the private cloud feature also allows them to access their data from anywhere at any time. Since these devices have been designed to be connected over the Internet, the hardcoded backdoor would leave user data open to hackers. GulfTech research and development team has recently published an advisory detailing a hardcoded backdoor and several vulnerabilities it found in WD My Cloud storage devices that could allow remote attackers to ...

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...

The latest Palo Alto Networks Unit 42 Cloud Threat Report found that sensitive data is found in 66% of cloud storage buckets. This data is vulnerable to ransomware attacks. The SANS Institute recently reported that these attacks can be performed by abusing the cloud provider's storage security controls and default settings. "In just the past few months, I have witnessed two different methods for executing a ransomware attack using nothing but legitimate cloud security features," warns Brandon Evans, security consultant and SANS Certified Instructor. Halcyon disclosed an attack campaign that leveraged one of Amazon S3's native encryption mechanisms, SSE-C, to encrypt each of the target buckets. A few months prior, security consultant Chris Farris demonstrated how attackers could perform a similar attack using a different AWS security feature, KMS keys with external key material, using simple scripts generated by ChatGPT. "Clearly, this topic is top-of-mind for both threat actors and ...

DefenseCode researchers have discovered a critical security vulnerability that allows remote unauthenticated attacker to remotely execute arbitrary code under root privileges in the UPnP (Universal Plug and Play) implementation developed by Broadcom and used by many routers with Broadcom chipsets. Routers with vulnerable Broadcom UPnP stack are mostly based on Broadcom chipset. " We have found that, in fact, same vulnerable firmware component is also used in at least two other Cisco Linksys models - WRT54G3G and probably WRT310N. Could be others. " researchers said . The vulnerability is located within the wanipc and wanppp modules of the Broadcom UPnP stack, which is used by manufacturers that deliver routers based on the Broadcom chipset. The UPnP service is intended to be used on local networks, but Rapid7 found that there are over 80 million devices on the Internet that respond to UPnP discovery requests, making them vulnerable to remote attacks. The vul...
