This will be an insightful night dedicated to Cybercrime and its bigger more dangerous cousin: Cyber-warfare. We will explore the drivers behind the radical shift, the software arsenal available and how and why you, the software developers, are both target and unwitting helpers.

Additional Information


19:00 Log4J, SpringShell and all that Jazz (or why bad things can happen to good software)

At the turn of the millennium IT organisations had about 60 days to fix software vulnerabilities. That meant from announcement to widespread exploitation took about two months. Fast forward to 2022 and, well, it’s not good. Zero day vulnerabilities have come and gone.

The world now have to learn how to deal with widespread exploitation happening before a fix is available.  In this session we’ll look at Cybercrime and its bigger more dangerous cousin: Cyber-warfare.

I’ll explore the drivers behind the radical shift, the software arsenal available and how and why developers are both target and unwitting helpers.

Quick demos of Log4Shell and SpringShell will help us understand the basics of how we make software vulnerable and maybe, what we can do to reduce the risks.  Governments are beginning to understand the threat as well and new ideas and directives are emerging. However these have consequences for developers too.

The last 20 years has been a long wake-up call. The next 20 may see software development change beyond recognition.

20:15 Java JEP’dy

Whatever Java related role you have now it’s been an unusually stress full few months for many of us. In recognition of this (and to be honest just because it’s a fun thing). Sonatype has been working with the London Java Community, Microsoft and a great developer called Hanno Embregts to create a game we can all play.

You can guess from the title that this game is inspired by the original Jeopardy TV series.

Our game consists of a series of clues that the contestants have to use to guess the question. For instance the clue “In Java 15 we said goodbye to this German rhinoceros”. might have the question “What is Nashorn”. Simple huh? Each successful answer scores points. Each wrong guess costs points. Winner takes all.

All the clues are Java related. Some of the categories we have include:

• Cryptic Keywords - Rryptic clues that match Java language reserved words

• Java through the Ages - History of Java of course

• Deprecated - Rarely used features

• Billy's cup of Joe - Clues about real Java tech from our very own Billy Korando
