🚨 Apple Pays Google $1 Billion for Gemini — While Google Pays Apple $20 Billion to Stay Default Search Engine.

Confused? You should be.

📱 Apple is reportedly finalizing a $1 billion-per-year deal to license Google’s Gemini AI.
That means Siri and Apple Intelligence could soon rely on Google’s model for advanced AI responses.

Apple, known for privacy and independence, now paying its biggest rival for AI power.

🌐Meanwhile, Google pays Apple a staggering $18–20 billion annually just to remain the default search engine in Safari.

That’s roughly 14–16 % of Apple’s yearly profit — simply for giving Google a front seat on your iPhone.

The irony?

Apple pays Google for AI.

Google pays Apple for users.

Both keep each other dominant — while regulators debate antitrust and competition worldwide.

💡 What This Shows
• Tech “rivals” are often each other’s biggest customers.
• Default positions and integrations are worth tens of billions.
• Even Apple, the world’s richest company, can’t ignore Google’s AI lead.
• True independence in AI may be far more expensive than we think.

VPNs may look similar from the outside, but each type works differently and offers different levels of security.

🔐 IPSec VPN

Enterprise grade, highly secure, and ideal for site to site connections.

Encrypts traffic at the network layer and is commonly used for connecting branch offices or data centers.

🌐 L2TP over IPSec

L2TP alone is not secure, but when paired with IPSec it becomes a reliable tunnel for remote users.

Still found in some legacy or mixed environments.

⚠️ PPTP VPN

Fast but outdated and considered insecure today.

Uses weak encryption and should not be used in any business setup.

🧩 SSL VPN

Modern, user friendly, and works over HTTPS, which makes it perfect for remote workers.

Allows controlled access to specific internal apps instead of exposing the entire network.
Choosing the right VPN depends on what your organisation needs: security level, performance, and how much access users should get.

If you need help setting up secure VPN connections or reviewing your remote work architecture, Cybernara can support you.

Types of Cyber Attacks You Should Know

📧 Phishing
Tricks users into revealing sensitive info using fake websites or messages.

🕵️ Man-in-the-Middle (MITM)
Intercepts data between users and services — silently stealing or altering it.

🌐 DDoS Attack
Overloads servers with traffic to crash or slow them down.

🧪 SQL Injection
Injects code into user inputs to access or manipulate databases.

🐞 Zero-Day Exploit
Targets unknown software flaws before developers can patch them.

💻 Cross-Site Scripting (XSS)
Inserts malicious scripts into trusted websites — affects other users.

🚨 Why it matters:
These attacks can disrupt operations, leak sensitive data, and cost businesses big. Awareness is the first step — protection is the next.

🔒 Cybernara provides end-to-end cybersecurity services to help you identify risks, protect your data, and respond to threats effectively.

Most people assume that once they’re online, their activity is completely private — but that’s far from the truth.

Your Internet Service Provider (ISP) has visibility into much more than you might expect. 
Depending on whether you’re using HTTP, HTTPS, or a VPN, the amount of data they can see changes dramatically.

🔴 HTTP:

Everything you do — including full URLs, text, images, messages, and form data — is visible to your ISP (and anyone intercepting your traffic). It’s like sending postcards: anyone along the way can read them.

🟠 HTTPS:

Adds a layer of encryption. Your ISP can still see which website you’re visiting (the domain), but not the specific pages, actions, or content. 

🟢 VPN:

Encrypts all your internet traffic before it leaves your device. Your ISP can only see that you’re connected to a VPN server — not which websites you visit, what services you use, or any of your activity.

In today’s digital landscape, where privacy is often traded for convenience, understanding this difference is essential.

If you value privacy and data security, using HTTPS-secured websites is a must — and pairing that with a reliable VPN takes it one step further.
🔐 Stay smart, stay secure.

At Cybernara, we believe digital awareness is the first step toward a safer internet.

When most people hear the word “hacker,” they instantly think of cybercriminals — the ones breaking into systems and stealing data.

But in the world of cybersecurity, not all hackers are villains.
Hackers come in different “hats,” each representing their intent, ethics, and skill level.

🕶️ Black Hat — The classic “bad guys.”

They exploit vulnerabilities for personal gain using methods like malware, ransomware, or DDoS attacks.

🤍 White Hat — The ethical defenders.

They work to find and fix vulnerabilities through penetration testing and security audits — often helping organizations stay safe.

⚫ Gray Hat — The blurry middle ground.

They expose flaws without permission — not always with malicious intent, but still crossing ethical lines.

💚 Green Hat — The curious beginners.

New to hacking, they experiment with tools and scripts, often learning through online communities and forums.

💙 Blue Hat — The avengers.

They hack for personal revenge or retaliation, using doxxing or site defacement — typically driven by emotion, not profit.

❤️ Red Hat — The vigilantes.

They target Black Hat hackers directly, launching aggressive counter-attacks — sometimes as extreme as the hackers they fight.

🎯 The takeaway:

Understanding hacker types helps organizations identify threats, predict behaviors, and build stronger defenses.

Not all hackers are enemies — some are the first line of defense in a digital war fought silently every day.

💡 At Cybernara, we simplify cybersecurity — making complex topics clear, visual, and actionable.

90% of phishing attacks start with email spoofing — and most could be stopped by three simple DNS records 👇

✅ SPF – Verifies that an email is sent from an authorized server.

✅ DKIM – Adds a digital signature to confirm the message wasn’t altered.

✅ DMARC – Tells mail servers what to do if an email fails SPF or DKIM.
💡 Why it matters:

Without these, anyone can send emails pretending to be your domain — putting your brand, customers, and employees at risk.
🧩 Benefits when properly configured:

• Blocks phishing & spoofing attempts

• Confirms sender legitimacy

• Protects your domain reputation
🔒 Implement SPF, DKIM & DMARC today — it’s one of the easiest wins in email security.

🔒 At Cybernara, we don’t just explain these protocols — we implement them.

From DNS setup to email policy alignment, our team ensures your domain is protected end-to-end.

💼 Because real cybersecurity starts before the attack happens.

🛡️ Penetration testing isn’t guesswork — it’s a craft built on the right tools.

From network scanning to web app exploitation to reverse engineering, each phase of a real assessment depends on a different skillset… and a different toolkit.

That’s why security teams rely on a mix of proven, battle-tested tools like:

• Metasploit for exploitation
• Burp Suite and OWASP ZAP for web app testing
• Nmap and Wireshark for network discovery and traffic analysis
• SQLMap, WPScan, and Acunetix for targeted vulnerability detection
• John the Ripper and Aircrack-NG for password and wireless testing
• IDA Pro, Kali Linux, BeEF, and others for deeper, specialized work

Each tool uncovers a different layer of weakness — and together, they expose the gaps attackers love to exploit.

🔐 At Cybernara, these aren’t just names on a list.

They’re part of our daily toolkit for delivering thorough, professional penetration tests across applications, cloud, networks, and infrastructure.

If your business needs a real security assessment — not a surface-level scan — we can help.

He bought a $300 smart vacuum.

It quietly sent a 3D map of his home overseas. 🌍

When he blocked the data — the vacuum died.

Turns out, it had an open debug port and a remote kill switch.

He reversed it and brought it back to life.

But it left one haunting question:

If your device stops working when you say “no” to data — do you really own it? 🤔

In 2000, a college student wrote a small script.

Within days, it infected 10 million computers, caused $20 billion in damages, and shut down global networks.

His name was Onel de Guzman — the creator of the infamous ILOVEYOU virus.

He admitted to writing it.

Yet he was never arrested.

Because back then, there were no cybercrime laws.

Sometimes, it’s not hackers we fear — it’s how unprepared our systems (and laws) can be. ⚠️

#CyberStory #CyberSecurity #HackingHistory #ILOVEYOUvirus

In the year 2000, a simple script written by a college student spiraled into one of the biggest cyber incidents in history. 💻🔥

What started as a small experiment quickly became a global outbreak — spreading through inboxes, crashing servers, and halting businesses everywhere.

Within days, 10 million computers were infected, causing an estimated $20 billion in damage. 🌍💸

The creator, Onel de Guzman, eventually admitted he wrote the malware…

but he was never arrested. 🚫👮‍♂️
Why?

Because back then, the world had no laws to prosecute cybercrime. ⚖️❗

A reminder that the real risk isn’t always the hacker, sometimes it’s how unprepared our systems, laws, and safeguards truly are. ⚠️🔐

Most Azure users focus on inbound access but egress traffic (outbound connections) is just as critical for network performance and security.

Here’s how Azure egress works 👇
1️⃣ Public IP on a VM

Each VM connects to the internet directly via a Public IP.

✔️ Simple setup

❌ Doesn’t scale as networks grow
2️⃣ Load Balancer with Public IP / Prefix

Multiple VMs share a Load Balancer for outbound access.

✔️ Enables scaling

❌ Requires manual port allocation to avoid SNAT exhaustion
3️⃣ NAT Gateway with Public IP / Prefix

Subnets use a NAT Gateway to manage outbound connections.

✔️ Scalable and predictable

✔️ Uses static IPs for consistent routing

✔️ Reduces SNAT port exhaustion risks
In short —

🧩 Public IP = Basic

⚙️ Load Balancer = Intermediate

🚀 NAT Gateway = Enterprise-ready

Designing the right egress strategy ensures performance, reliability, and secure outbound traffic flow across your workloads.

At Cybernara, we help organizations optimize and secure their Azure environments — from network design to end-to-end cloud hardening.
