Question 1

What primary operational change did Cloudflare implement regarding API access to enhance security?

They required all API clients to use IP whitelisting to access api.cloudflare.com. They completely closed all HTTP (port 80) connections to api.cloudflare.com, only allowing HTTPS connections. They implemented a 403 Forbidden response for all HTTP requests to api.cloudflare.com. They introduced mandatory captcha challenges for all API HTTP connections on port 80.

Question 2

According to the episode, why does malware authoring in less-common programming languages reduce detection rates by antivirus systems?

Less-common languages produce binaries with different internal representations and function calls, which confound signature-based static analysis. Static analysis tools are deliberately designed to ignore non-C and C++ binaries to reduce false positives. Malware written in less-common languages is automatically flagged as safe by AV due to low prevalence and trust. Using uncommon languages prevents malware from running under modern operating systems, thus evading detection at runtime.

Question 3

What key feature or approach does the proposed EU OS emphasize to achieve sovereignty and security for the EU public sector?

Partnering exclusively with Microsoft to develop a custom Windows 11 variant with EU privacy enhancements. Building a completely new Linux kernel tailored exclusively to EU requirements and hardware. Deploying a cloud-only thin client approach where all software runs remotely to avoid any local data storage. Using an open source, Fedora-based Linux distribution with no telemetry and strict data control complying with GDPR.

Question 4

What was the nature and effect of the automated phishing attack on Troy Hunt’s Mailchimp account?

An automated phishing site collected username, password, and one-time password quickly, then immediately logged in to export his mailing list before he could act. His Mailchimp credentials were stolen in an unrelated data breach months before and reused in credential stuffing attempts. He received a spam email with a malicious attachment that installed malware to extract stored credentials from his browser. A social engineering phone call tricked him into revealing his Mailchimp password live.

Question 5

Why does EU OS aim to be a common base for public EU bodies rather than a collection of diverse Linux distributions?

So that the EU can build its own proprietary software stack independent of global open source projects. To enable shared management tools, mutualized resources, and easier deployment and maintenance at organizational and sector levels. To restrict user choice and ensure all public sector users have identical hardware to avoid compatibility issues. Because a single Linux distribution is legally required to comply with all EU national laws.
