Let me tell you about the alert that changed the way I approach triage. It was a Tuesday night shift. The queue had 47 open alerts and this one kept getting pushed to the bottom. It looked boring. Severity: Low. Rule: "Repeated failed login attempts — internal host." Same thing that fires a hundred times a week across the environment. Most of them are users who forget their passwords after a long weekend. So it sat there. For six hours. When I finally opened it, something felt off. The failed logins weren’t from a user workstation. They were coming from a server in the DMZ — a web application server that had no business authenticating against internal Active Directory accounts. And the account it was hammering? A service account. Not a user. Service accounts don’t forget their passwords. I pulled the raw logs. 847 failed attempts in 40 minutes against 12 different service accounts. Methodical. Sequential. Not random. This wasn’t a lockout. This was credential stuffing — someone had foothold on that web server and was quietly trying to move laterally into the domain. We isolated the server within the hour. Forensics found a PHP webshell that had been sitting there for 11 days. ELEVEN DAYS. The initial access had flown completely under the radar. What tipped us off wasn’t a flashy alert — it was a boring, low-severity, easy-to-skip log that one tired analyst almost ignored for an entire shift. 💡 THE LESSONS I TOOK FROM THIS: ✅ Low severity ≠ low importance. Context is everything. Always ask: does this behaviour make sense for this asset? ✅ Know your environment. That alert only stood out because I knew DMZ servers shouldn’t be touching AD auth. Asset knowledge is a superpower. ✅ Service accounts behaving like users is always suspicious. They don’t fat-finger passwords. ✅ Alert fatigue is a real threat. If your queue is so full that low-severity alerts sit for 6 hours, your detection strategy needs review — not just your analysts. ✅ The attacker’s best friend is the alert nobody investigates. Don’t give them that gift.

Here is a rewritten post ready to share on your Skool cybersecurity channel: 🚨 CRITICAL SECURITY ALERT — SAP S/4HANA Users, Pay Attention! A critical vulnerability has just been flagged that enterprise teams and security professionals need to know about immediately. If your organisation runs SAP S/4HANA, this one is not to be ignored. CVE-2026-0498 | CVSS Score: 9.1 — CRITICAL📅 Published: January 15, 2026 What's the threat?A remote-enabled function module in SAP S/4HANA allows attackers with admin privileges to modify source code without proper authentication checks — leading to code injection and full OS command execution. In plain English? A bad actor could gain complete control of your enterprise ERP system. Who is affected?Anyone running SAP S/4HANA in their environment. What should you do RIGHT NOW? ✅ - 🔴 Apply SAP's January 2026 Security Patch Day updates immediately — don't wait - 👤 Review and audit all admin privilege assignments — least privilege principle applies here - 👁️ Monitor for any unauthorised source code modifications in your environment - 🔒 Implement or tighten change management controls to catch suspicious activity early 💡 Key takeaway for the community: This is a perfect real-world example of why privilege management and patch hygiene aren't just best practices — they're your first line of defence. A 9.1 CVSS score means this is about as serious as it gets. Stay patched. Stay vigilant. 🔐 Would you like me to turn this into a weekly "Threat of the Week" post format you can reuse for future alerts?
