On this week’s show Patrick Gray and James Wilson are joined by guest co-host Ollie Whitehouse, the CTO of the UK’s NCSC, to talk through the week’s news, including:
- Iranian hackers take down a small-scale power generator in the UK
- Siemens PLCs in critical US sectors are also being targeted… We’re stumped on who could be behind that one, too.
- Microsoft fixed a CVSS 10 deserialisation bug in Entra before someone else found it and owned the planet
- Prompt injection isn’t going away
- LLMs are deceiving us meat sacks and it’s a worry
- Much, much more…
This week’s show is brought to you by Okta. VP of Threat Intel Brett Winterford joins the show in this week’s sponsor interview to talk James through how the company is turning its plethora of accumulated data into free alerting for its customers. They also chat about Okta’s new threat intelligence product line.
