6,482 readers analyzed this breakdown last month.

Introduction

• The 2024 Oldster Water Facility hack exposed critical weaknesses in SCADA enviroments that extend far beyond utilities. In this breakdown, we identify how the attack unfolded, what vulnerabilities were exploited, and what your organization can do today to tighten its cybersecurity posture.

  
  

Inside the Oldster SCADA Breach

• How attackers bypasses weak controls to ener the SCADA environment.

• Key vulnerabilities exploited, including outdated systems and lack of segmentation.

• Impact on operations and how the attack disrupted critical water services.

• Tactics used by the threat actors to escalate privileges and move laterally.

  
  

Common Security Mistakes in Organizations

• Infrequent or ineffective employee training

• Outdated firmware, devices, or software patches

• Weak or default passwords still in use

• Lack of visibility into remote access points

• Poor documentation of system changes

• No standardized process for configuration

Sentinel Watch (& Watch+) members receive step-by-step checklists and threat breakdowns addressing each of these gaps in depth. Sentinel Watch

How Phishing Opens the Door

• Email remains the #1 breach entry - over 90% of attacks start here.

• SCADA teams often lack tailored phishing training and mock attack drills.

• Attackers mimic vendor logins, spoof internal messages, or bait with urgent requests.

• Once clicked, these emails can give attackers full visibility or remote access.

Audit Smarter, Not Later

• Skip the guesswork - audits should test teal-world breach scenarios, not just paperwork.

• Too many orgs rely on outdated vendor checklists that miss modern threats

• A solid audit includes:

  • Live testing of SCADA communication paths

  • Verification of patching, segmentation, and access control

  • A real incident response walk-through

Sentinel Watch+ members unlock proven audit templates, gap analysis tools, and priority access to expert reviews. Sentinel Watch

Conclusion

• The 2024 Oldster breach wasn't just a wake-up call for one utility - it exposed flaws still common across critical infrastructure. From phishing blind spots to poor SCADA visibility, these threats arn't rare. They're everywhere....Your systems might walready be vulnerable - the difference is whether you're prepared.

Sentinel Watch members get exclusive checklists, breach drills, and audit-ready guidance built by operators who've seen what happen when things go wrong.

Stay ahead. Stay Secured.

From the Operators Chair:

"As someone who's operated SCADA systems under extreme pressure, I can tell you firsthand - most breaches start the same way: outdated access controls, zero alerting, and teams caught off guard. If you manage any SCADA enviroment, dont wait for the next breach to expose your blind spots. Sentinel Watch is built for the ones looking for tactical updates, proven audit tools, and real-world breakdowns that keep your system sharp. Lets stay ahead & be pro-active, not reactive."
