Risky Business #783 -- Evil webcam ransomwares entire Windows network

Risky Biz

On this week’s show Patrick Gray and Adam Boileau discuss the week’s cybersecurity news with special guest Rob Joyce, a Former Special Assistant to the US President and Director of Cybersecurity for NSA.

They talk through:

• A realistic bluetooth-proximity phishing attack against Passkeys
• A very patient ransomware actor encrypts an entire enterprise with a puny linux webcam processor
• The ESP32 backdoor that is neither a door nor at the back
• The X DDoS that Elon said was Ukraine is claimed by pro-Palestinian hacktivists
• Years later, LastPass hackers are still emptying crypto-wallets
• …and it turns out North Korea nailed {Safe}Wallet with a malicious docker image. Nice!

Rob Joyce recently testified to the US House Select Committee on the Chinese Communist Party, and he explains why DOGE kicking probationary employees to the curb is “devastating” for the national security staff pipeline.

This week’s episode is sponsored by SpecterOps, makers of the BloodHound identity attack path mapping tool. Chief Product Officer Justin Kohler and Principal Security Researcher Lee Chagolla-Christensen discuss their pragmatic approach to disabling NTLM authentication in Active Directory using BloodHound’s insight.

This episode is also available on Youtube.
