Ransomware: A Programmer's Perspective on Prevention and AI Defense

Image
Ransomware—the very mention of the word can send shivers down the spines of IT professionals. It's more than just malware; it’s a modern-day hostage crisis for data. In minutes, it locks critical files behind unbreakable encryption, demanding payment for their release. Entire organizations have been brought to their knees, with billions in damages caused worldwide. But here’s the good news: we’re not powerless in the face of ransomware. I’ve experienced it firsthand. During a live attack, our team, with the support of our MSSP partner Oxiqa , managed to restore critical services within an hour, ensuring business continuity. Through a combination of advanced defenses, thorough system scans, and precise remediation, we eradicated the threat and secured our systems within 24 hours. This experience drove home a crucial lesson: prevention is the key. By combining proactive measures, cutting-edge technologies like EDR and XDR, and AI-powered solutions like SentinelOne, we can detect—an...

The Ultimate Guide to DNS: Building Your Own DNS Server and Managing It Effectively

Image
The Domain Name System (DNS) is often described as the "phonebook of the internet," as it translates human-readable domain names into machine-readable IP addresses.

Turning a Joke into Innovation: AI Integration in our Daily Task Manager

Image
Recently, I developed a ticket management system to streamline day-to-day operations at my workplace. The system is as simple as you’d expect: users can create tickets with tentative completion dates, and team members can post updates on those tickets. However, today I’m not here to discuss how I built the system. Instead, I want to highlight how I integrated AI to help users generate updates with prompts or even summarize the updates they wish to post. It all started as a joke. In today’s world, we rely heavily on AI tools like ChatGPT, BART, and Deep.ai to rephrase our writing and ensure grammatical accuracy. It’s no secret that many of us use grammar tools, whether AI-powered or not. At our workplace, quite a few users do the same. This is nothing to be ashamed of, and no one should be concerned about it. In fact, I believe it’s essential to present ourselves and our ideas clearly and polished. After all, while English may be our primary workplace language, it’s not our mother tong...

Zapping Through Multicast Madness: A Fun Python Script to Keep Your IPTV Streams Rocking!

Image
Hey there, stream wranglers! If you’re in the wild world of IPTV —think hotels, cruise ships, or sports bars blasting live channels to a gazillion screens—you know multicast UDP streams are the unsung heroes of efficient video delivery. But UDP is like that carefree friend who doesn’t check in, leaving you wondering, "Is this stream even alive?"   In this post, we’re looking at a Python script I built to help a friend whose streams randomly drop. It checks both multicast and unicast UDP streams, and if one goes down, it can (optionally) send a heads-up via Telegram. It’s got retries, scheduling, and just enough socket magic to keep things running smooth. Let’s take a look under the hood!  Table of Contents What’s the Deal with Multicast UDP Streams?
