News Roundup - Scattered Spider Bites MSPs, Microsoft Rethinks Kernel Access, North Koreans Seem Good at Their Illicit Jobs

There’s lots of juicy stories in our monthly security news roundup. The Scattered Spider hacking group makes effective use of social engineering to target MSPs, Microsoft pushes for better Windows resiliency by rethinking kernel access policies for third-party endpoint security software, and the US Justice Department files indictments against alleged operators of laptop farms that enabled North Koreans to get IT roles at more than 100 US companies (and apparently some of them were pretty good at their jobs).

We dig into a Sophos report that finds shifts in ransomware tactics (less encryption, more ransom), discuss the potential privacy implications of defunct DNA company 23andMe selling customer data to a non-profit, and examine why Denmark wants to replace Microsoft Office with LibreOffice as other EU countries consider non-US cloud and Internet infrastructure.

We also talk about a Google outage triggered by failed API checks, a big copyright infringement suit being brought against AI firm Midjourney, Salesforce configuration risks, serious printer vulnerabilities affecting major brands, and critical Cisco ISE patches. | LISTEN NOW

AI Security Submissions at Curl Dev

Curl is a widely used open source tool and library for transferring data. On today's Day Two DevOps we talk with curl creator Daniel Stenberg. Daniel discusses how AI has complicated curl's bug bounty program. Bug hunters use AI to look for bugs, which has ramped up the number of submissions. But the output generated by AI is often incorrect. This creates more work for the project's developers as they try to discern what's accurate and what's a hallucination.| LISTEN NOW
