  Android users installing apps from third-party app stores are at risk of the BlackRock malware. How can this malware be stopped? BlackRock malware is yet another threat that Android users have to worry about. This newly-discovered malware can attack a variety of different apps, stealing your information in the process. Before you download another app, make sure you know what BlackRock malware is, and how you can protect yourself. What Is BlackRock Android Malware? In May 2020, security company, ThreatFabric, discovered a digital danger that affects Android devices: BlackRock malware. However, analysts quickly discovered that BlackRock malware actually isn’t a new threat. BlackRock malware stems from the leaked Xeres malware source code, which is a type of LokiBot banking Trojan. Despite being based on a banking Trojan, BlackRock malware doesn’t just affect banking apps. It also targets shopping, lifestyle, social, entertainment, and even dating apps. This widespread cov...

  What is SDN? Software-Defined Networking (SDN) is a network architecture approach that enables the network to be intelligently and centrally controlled, or ‘programmed,’ using software applications. This helps operators manage the entire network consistently and holistically, regardless of the underlying network technology. WHITE PAPER NFV and SDN: The Next Step in the Evolution of the Networks The SDN Architecture is: DIRECTLY PROGRAMMABLE Network control is directly programmable because it is decoupled from forwarding functions. AGILE Abstracting control from forwarding lets administrators dynamically adjust network-wide traffic flow to meet changing needs. CENTRALLY MANAGED Network intelligence is (logically) centralized in software-based SDN controllers that maintain a global view of the network, which appears to applications and policy engines as a single, logical switch. PROGRAMMATICALLY CONFIGURED SDN lets network managers configure, manage, secure, and optimize network re...

  What is Steganography? Steganography is the practice of hiding a secret message inside of (or even on top of) something that is not secret. That something can be just about anything you want. These days, many examples of steganography involve embedding a secret piece of text inside of a picture. Or hiding a secret message or script inside of a Word or Excel document. The purpose of steganography is to conceal and deceive. It is a form of covert communication and can involve the use of any medium to hide messages. It’s not a form of cryptography, because it doesn’t involve scrambling data or using a key. Instead, it is a form of data hiding and can be executed in clever ways. Where cryptography is a science that largely enables privacy, steganography is a practice that enables secrecy – and deceit. How Steganography is Used Today Steganography has been used for centuries, but these days, hackers and IT pros have digitized it to do some pretty creative things. There are a number of...

  Introduction to Web3     Centralization has helped onboard billions of people to the World Wide Web and created the stable, robust infrastructure on which it lives. At the same time, a handful of centralized entities have a stronghold on large swathes of the World Wide Web, unilaterally deciding what should and should not be allowed. Web3 is the answer to this dilemma. Instead of a Web monopolized by large technology companies, Web3 embraces decentralization and is being built, operated, and owned by its users. Web3 puts power in the hands of individuals rather than corporations. Before we talk about Web3, let's explore how we got here. The early Web Most people think of the Web as a continuous pillar of modern life—it was invented and has just existed since. However, the Web most of us know today is quite different from originally imagined. To understand this better, it's helpful to break the Web's short history into loose periods—Web 1.0 and Web 2.0.
