N‑able SOC Stories – From Detection to Defense: Wins from May’s Cybersecurity Battlefront

When cybercriminals innovate, your security posture can’t afford to be reactive. Global attack campaigns are testing every gap, from MFA fatigue to exploiting forgotten software modules. At N‑able, we know MSPs and SMBs face constant pressure: keep operations running, protect customer data, and do it all under growing compliance and financial risk.

That’s why May was another month where Adlumin MDR quietly made the difference, detecting and disrupting high-risk incidents before they could become business disasters. These aren’t just wins for cybersecurity. They’re wins for operational resilience, customer trust, and your business.

What Organizations Faced in May

Modern adversaries don’t just launch attacks. They execute structured campaigns targeting the weakest link. In May, we saw tactics designed to bypass controls and pivot quickly:

• Credential Abuse and MFA Exploitation
  Threat actors increasingly harvested credentials and probed MFA configurations, looking for that single shot at escalation.
• Forgotten Systems, Big Risk
  Deprecated web services are more than legacy clutter. They’re entry points waiting to be exploited. Reconnaissance scans left an unmistakable pattern that required immediate patch acceleration.
• Weaponized PowerShell for Stealthy Moves
  Living-off-the-Land binaries such as PowerShell were leveraged for lateral movement and privilege escalation, often under the radar of basic monitoring.
• Cloud API Misuse to Blend In
  Adversaries know where your sensitive data lives. In May, activity spikes on Office 365 Graph API suggested attempts to weaponize legitimate services for mass file access.
• Pre-Ransomware Indicators
  We observed behavior consistent with advanced ransomware staging: Local Security Authority Subsystem Service (LSASS) dumps and beaconing intended to set the stage for encryption.

These patterns illustrate a central truth: Attack surfaces expand as businesses scale. The goal isn’t zero risk; it’s closing gaps faster than adversaries can exploit them. That’s where Adlumin MDR comes in.

Adlumin MDR Response: Speed + Strategy

Stopping a breach isn’t just about sounding the alarm. It’s about what happens next. This is where our MDR capabilities shift the narrative from “Oh no” to “Handled.”

• Under 25 Minutes:Average time from first compromise indicator to actionable containment guidance
• Zero Confirmed Encryptions:Across monitored environments because early action pays off
• Full Lifecycle Support:Detection, triage, forensic guidance, and recovery consulting

Example interventions in May:

• Proactive Interruption: Intercepted LSASS dump attempts during ransomware staging. Recommended device isolation and credential rotation before encryption steps began.
• Credential Attack Neutralization: Flagged MFA bypass trails and guided immediate resets with stronger enforcement strategies.
• Cloud Risk Containment: Detected anomalous Graph API query spikes and advised ACL restructuring to cut off exfiltration paths.

For MSPs and SMBs, response time is more than an SLA. It’s the difference between a headline-making breach and business-as-usual.

Operational Takeaways & Partner Guidance

Awareness alone doesn’t stop attacks. The insights from May underscore security fundamentals that deliver measurable resilience:

• Move to phishing-resistant MFA now as push fatigue attacks are real.
• Harden the edge: Accelerate patch cycles for all internet-facing systems.
• Apply conditional access policies to SaaS ecosystems.
• Enforce centralized PowerShell monitoring + Antimalware Scan Interface (AMSI) for inline defense.

Security isn’t static, and neither is your business. These measures aren’t just about blocking threats. They’re about enabling secure growth.

What We Prevented – and How We Know

Every save is backed by visibility and MITRE ATT&CK-aligned telemetry. This month, we saw and stopped:

• Initial Access:Exploit Public-Facing Application (T1190)
• Execution: Multiple MITRE techniques detected and disrupted, for example: PowerShell Command and Scripting Interpreter (T1059.001),
  Signed Binary Proxy Execution (T1218),
• Ingress Tool Transfer (T1105),
• Lateral Movement (TA0008)
• Persistence:Credential Access (TA0006)
• Exfiltration:Cloud Service Exfiltration (T1567.002)

Confidence: High, confirmed by correlated behavioral and forensic data.

These aren’t hypothetical risks. They’re documented patterns attackers successfully leveraged against victims that didn’t have MDR on their side.

The Bigger Picture: From Alerts to Assurance

May proves a critical point: prevention is measurable. For every intercepted attempt, we protected revenue continuity, customer confidence, and brand reputation. That’s the real value of Adlumin MDR: actionable outcomes that turn uncertainty into control.
