Write a security news roundup for my team

Write a concise security news roundup from the items I provide. Source material: [PASTE articles, advisories, vendor bulletins, or links with summaries] Audience: [e.g. "IT team", "all employees", "executives", "customers"] Our environment: [key platforms, vendors, and software we run - e.g. "Microsoft 365, Okta, Fortinet VPN, AWS"] Format and length: [e.g. "weekly email under 500 words", "Slack post"] Rules: - Use only the facts in my sources. Don't add CVE numbers, severity scores, dates, or victim names that aren't there; mark gaps [CONFIRM]. - Lead with what affects us. If an item touches a product in our environment, put it at the top. - Match depth to the audience: executives get business impact; IT gets affected versions, CVEs, and fixes; employees get one clear thing to do differently. Structure: 1. Act now: items that need action from us, each with what's affected, the risk in one sentence, the action, and a suggested owner. 2. Threats and advisories: active campaigns, phishing themes, and vulnerabilities worth watching (15-25 words each). 3. Notable stories: up to 5 interesting developments, one line each. 4. Tip of the week: one practical security habit tied to this week's news. 5. Sources: each source I provided, next to the item it supports. Keep it skimmable: short lines, no hype, no fear-mongering.
