Should your laptop ever get stolen and fall into the wrong hands, you would probably be comfortable in the knowledge that the data on it is protected by full disk encryption. But what if a malicious adversary could get around that encryption and access the data anyway? F-Secure's Olle Segerdahl and Pasi Saarinen have discovered a flaw that allows attackers to do just that, and it affects almost all modern corporate laptops - probably yours too. Olle and Pasi join us today to talk about bypassing the mitigations vendors have put in place against cold boot attacks, and what companies can do to mitigate the risk.

How can companies know if their security investments are actually working? Getting attacked is the ultimate test, but hiring a red team is a less disruptive way to find out. These guys rely on technical chops, acting skills and pure creativity to engage in an all-out attack on a company's defenses.

Joining us this episode is Tom Van de Wiele, Principal Security Consultant at F-Secure, to talk about how red teaming can help companies improve their security posture, his tricks for hustling his way into a company, and why the coffee machine is a red teamer's best friend while on a job (but not for the caffeine). Be warned: You'll never look at strangers around your office the same way again.

Video - The Value of Red Teaming, with Tom Van de Wiele

Disinformation. Fake news. Social media manipulation. Lately another dark side of the internet has come into focus - its use as a tool for deception. Technologies like machine learning and artificial intelligence are being employed to play hoaxes and mislead on purpose. Seeing is no longer believing - and moving forward, it's only going to get harder to distinguish facts from falsehoods.

Andy Patel from F-Secure's Artificial Intelligence Center of Excellence has been studying this phenomenon. He joins Janne in this episode to share what he's learned about Twitter bots, deepfakes, voice cloning and the tools that make it all possible. Do concerns about these technologies outweigh the benefits, and how will they affect society?
