PwnFunction

PwnFunction is a computer security channel. It uses simple animations to explain how attacks on websites and software work.

Most videos are between eight and 18 minutes long. Each one picks a single type of vulnerability or a real security incident and breaks it down step by step. Animated characters and diagrams keep the ideas clear, even when the code behind them is tricky. The focus is on understanding why a flaw exists and how developers can prevent it.

Some highlights include:

This video explains cross-site scripting, a common flaw that lets attackers run their own code on someone else’s website.

This one shows why the random numbers made by computers are not always truly random, and why that matters for security.

This video looks at a serious bug that sat unnoticed in widely used code for 12 years.

The channel has around 238,000 subscribers.

Cyber security is a fast-growing area of computing and software engineering, with apprenticeships and degree routes into it. PwnFunction is a good way to see how real systems fail and how careful engineering keeps people safe online. It suits students taking GCSE or A level Computer Science who want to go beyond the syllabus. The channel explains attacks so that viewers understand defence, and students should only ever practise these skills on systems they own or have permission to test. Organised competitions and courses offer a safe, legal way to do that.
