Your Social Media Everyone knows what is like to "Work from home" nowadays right? since the current situation went worldwide most of the companies moved to work from home. Which led lot of companies open to cyber attacks. Most of the cyber attacks were targeted to the employees of the companies. It's not just their company profiles/emails/user accounts but also their social network accounts as well. Those users/employees were open to attacks due to the fact that they were not using an extra layer of security for their social profiles and also their email accounts.

Surprising right? Apple is officially stepping into the search arena with its own AI-powered "answer engine". Internally called "World Knowledge Answers," this new system is designed to provide direct, multimodal summaries using text, images, and video. Why now? The Google Partnership Dilemma For years, Google has paid Apple upwards of $20 billion annually to remain the default search engine on Safari. However, recent antitrust rulings have threatened this partnership, forcing Apple to build its own "Siri Overhaul" to maintain control of the user experience. The 2026 Strategic Advantages 1. Smarter Siri (The Answer Engine) Currently, Siri often redirects you to a Google search link. By early 2026, the new Siri—powered by a hybrid of Apple's on-device models and Google...

PASSWORDS What is a password? Let's start there. The simplest definition is - it is a key to a door that unlocks some stuff . May be important or not. I'm gonna keep referring to passwords as "Keys" because throughout the article it's gonna be very important! (just wait for my climax, it's QT ending) Usually, we keep our home/rooms locked because we don't want any outsiders creeping at our PRIVATE things! Even some of our things are very private, especially we don't want our parents/family to look at them either.  Okay, let's get back to the topic. PASSWORDS. In the logical world (Websites, Software, Applications, Etc.) A password is a method to identify the person who is gaining access to a system/data/application.
