file cache | Breaking Cybersecurity News | The Hacker News

First announced over five years ago, ex-Google engineer Kent Overstreet is pleasured in announcing the general availability of a new open-source file-system for Linux, called the Bcache File System (or Bcachefs ). Bcachefs is a Linux kernel block layer cache that aims at offering a speedier and more advanced way of storing data on servers. Bcachefs promises to provide the same performance and reliability as the consecrated EXT4 and XFS file systems while having features of the ZFS and Btrfs file systems . Features that Bcachefs Supports Bcachefs supports all the features of a modern file-system, including: Checksumming to ensure data integrity Compression to save space Caching for quick response Copy-on-Write (COW) that offers the ability for a single file to be accessed by multiple parties at once What's coming next for Bcachefs It seems that some of the features in Bcachefs are limited or missing, which includes: Snapshots Erasure codi...

Reading a 'Note' created by anyone on the Facebook could trick you automatically to do malicious attacks against others unknowingly. A Security researcher Chaman Thapa, also known as chr13 claims that the flaw resides in 'Notes' section of the most popular social networking site - Facebook, that could allow anyone to launch the distributed denial-of-service (DDoS) attack of more than 800 Mbps Bandwidth on any website. A Distributed Denial-of-Service (DDoS) attack is one in which multiple compromised systems attacks a single target system or service to make it unavailable to its intended users. The flood of incoming requests essentially forces the target system or service to shut down, thereby denying service to the system to its legitimate users. While demonstrating the vulnerability on his blog , he explained that Facebook allows its users to include tags inside the post in order to draft a note with beautiful related images from any source. Faceb...

The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...
