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.

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...
