This course, developed by the University of Helsinki and MinnaLearn, helps learners gain a basic understanding of AI concepts such as machine learning, neural networks, and AI ethics. It includes hands-on exercises to apply AI techniques to real-world problems.

Developed by the University of Helsinki and MinnaLearn, this course helps students build practical skills in AI programming and machine learning. It covers topics such as neural networks, optimization, and advanced algorithms, while providing hands-on exercises to design and implement real AI models.

This course provided me an overview of essential cybersecurity concepts. It familiarized me with the TryHackMe platform and its interactive learning environment.

This course was a series of three training sessions led by Gynvael Coldwind, a top security researcher and founder of the Dragon Sector CTF team, focusing on the fundamentals of reverse engineering and assembly language.

Part I included a live demo showing the entire reverse engineering process from start to finish. It also covered the purpose and applications of reverse engineering (RE/RCE), challenges in the field, and an overview of essential tools such as disassemblers, debuggers, and process monitoring tools.

Part II focused on x86-64 assembly language, discussing Intel and AMD manuals, a simplified memory model, CPU registers, and interactions with operating systems and libraries.

Part III explored advanced reverse engineering techniques, including a top-down approach, reconnaissance, identifying significant code, and elevating code to higher-level languages, along with practical examples and demonstrations. The course also covered how to put what you learned into practice.

This course, led by Gynvael Coldwind, was designed to provide attendees with an in-depth understanding of files from an operating system perspective. Attendees learned about the nature of files, lesser-known file system features such as sparse files, alternate data streams (ADS), and encrypted files, and common approaches to file attributes and permissions. The course covered various types of files and pseudo files in different file systems, how software interacts with files, potential security risks, and the hidden complexities in seemingly simple file path mechanisms.

This course was a live demonstration of how seemingly insignificant information left by an individual online can lead to uncovering the details of an entire scam campaign, including identifying other victims of the fraud. The presentation covered topics such as metadata, usernames, photos, social media details, and the correlation of these data points.

This live course demonstrated a cold boot attack and showed how to bypass Full Disk Encryption (FDE) by physically freezing memory chips to recover encryption keys. The session included a real-time FDE password recovery and unlocking of a laptop’s encrypted hard drive.

This comprehensive training course provided an efficient way to learn about artificial intelligence. The course included an introduction to AI concepts, an overview of various AI tools and offline chatbots, and covered topics such as multimedia content creation, personal development tools, business management, and the role of AI in OSINT.

This course, taught by Gynvael Coldwind, explored fundamental concepts in computer science and cybersecurity. Topics included value representation, numeric systems such as hexadecimal, practical bit operations, signed and real number representation, and text encoding, giving attendees a solid foundation in how data is structured and manipulated in computing.
