A cybersecurity researcher today disclosed technical details and proof-of-concept of a critical remote code execution vulnerability affecting OpenWrt , a widely used Linux-based operating system for routers, residential gateways, and other embedded devices that route network traffic. Tracked as CVE-2020-7982 , the vulnerability resides in the OPKG package manager of OpenWrt that exists in the way it performs integrity checking of downloaded packages using the SHA-256 checksums embedded in the signed repository index. While an 'opkg install' command is invoked on the victim system, the flaw could allow a remote man-in-the-middle attacker in a position to intercept the communication of a targeted device to execute arbitrary code by tricking the system into installing a malicious package or software update without verification. If exploited successfully, a remote attacker could gain complete control over the targeted OpenWrt network device, and subsequently, over the netwo

Earlier this year, Facebook came across a bunch of duplicate SSL certificates for some of its own domains and revoked them immediately with the help of its own Certificate Transparency Monitoring Tool service. Digital certificates are the backbone of our secure Internet, which protects sensitive information and communication, as well as authenticate systems and Internet users. The Online Privacy relies heavily on SSL/TLS Certificates and encryption keys to protect millions of websites and applications. As explained in our  previous article on The Hacker News , the current Digital Certificate Management system and trusted Certificate Authorities (CAs) are not enough to prevent misuse of SSL certificates on the internet. In short, there are hundreds of Certificate Authorities, trusted by your web browsers and operating systems, that has the ability to issue certificates for any domain, despite the fact you already have one purchased from another CA. An improper

Super Low RPO with Continuous Data Protection: Dial Back to Just Seconds Before an Attack Zerto , a Hewlett Packard Enterprise company, can help you detect and recover from ransomware in near real-time. This solution leverages continuous data protection (CDP) to ensure all workloads have the lowest recovery point objective (RPO) possible. The most valuable thing about CDP is that it does not use snapshots, agents, or any other periodic data protection methodology. Zerto has no impact on production workloads and can achieve RPOs in the region of 5-15 seconds across thousands of virtual machines simultaneously. For example, the environment in the image below has nearly 1,000 VMs being protected with an average RPO of just six seconds! Application-Centric Protection: Group Your VMs to Gain Application-Level Control   You can protect your VMs with the Zerto application-centric approach using Virtual Protection Groups (VPGs). This logical grouping of VMs ensures that your whole applica

In the era of Government surveillance, ensuring the security and safety of our private communications regardless of platform – email, VOIP, message, even cookies stored – should be the top priority of the Internet industry. Some industry came together to offer Encryption as the protection against government surveillance, but some left security holes that may expose your personal data. A critical issue on Instagram's Android Application has been disclosed by a security researcher that could allow an attacker to hijack users' account and successfully access private photos, delete victim's photos, edit comments and also post new images. Instagram , acquired by Facebook in April 2012 for approximately US$1 billion, is an online mobile photo-sharing, video-sharing and social networking service that enables its users to take pictures and videos, apply digital filters, and share them on a variety of social networking services, such as Facebook, Twitter, Tumblr and Flickr.
