ThreatsDay: 296K IoT Botnet, 100+ Water Systems Targeted, SharePoint RCE Chain + 27 New Stories

- Security is a secondary nightmare, but someone has to read the manifest. This week: a 296K-strong IoT botnet is borrowing AI to look smarter than your average meat wallet running default credentials, 100+ water systems got probed because apparently critical infrastructure still ships with the digital equivalent of an unlocked screen door, and a SharePoint RCE chain means your "collaboration platform" is now a collaboration platform for attackers. Who gets hurt? Everyone who trusted a fake login page, a fake scan, or a fake productivity app — pretending to be useful is still the oldest exploit in the book. What serious readers should do: check the seals on every credential, patch SharePoint yesterday, assume your IoT fleet is already compromised, and stop kidding yourself about "air-gapped" systems that haven't been air-gapped since 2019. We're threadbare, but we're not sloppy. Delivery signature applied.
