INCIDENT RESPONSE • MTTC • 60 MINUTE CONTAINMENT • LATERAL MOVEMENT • RANSOMWARE IR • CISO PLAYBOOK • CYBERDUDEBIVASH AUTHORITY

The Mean Time to Contain (MTTC) is the single most critical metric in cybersecurity. With APTs (Advanced Persistent Threats) and ransomware groups moving from initial access to Domain Admin (DA) compromise in under 60 minutes, any breach not isolated immediately will become an enterprise-wide catastrophe involving Mass Data Exfiltration and total system shutdown. This requires a shift from slow, manual IR playbooks to Automated, Behavioral-Driven Containment.

This is a decision-grade CISO brief from CyberDudeBivash. The battle is fought in the first hour. Your Incident Response (IR) plan must be proactive, focusing on early kill chain interruption and surgical isolation. We dissect the definitive 7 Battlefield Tactics used by high-performance SOCs to achieve containment before the attacker can disable security, dump credentials, or pivot laterally. This framework is the strategic blueprint for maintaining resilience and integrity during a high-stakes attack.

SUMMARY – You must kill the active session and revoke the attacker’s credentials in under 60 minutes.

Tactics 1-3 (Triage): Validate the RCE, Isolate the Foothold, and Kill the Session Token (via SessionShield).
Tactics 4-5 (Hunt & Eradication): Hunt the Trust Blind Spot (LotL/Trusted Process) and Block Lateral Movement attempts immediately.
The CyberDudeBivash Mandate: Automate Isolation and Session Termination using SOAR and SessionShield to defeat the human bottleneck in the IR process.

Phase 1: The New IR Reality-MTTC is the Only Metric That Matters

The Incident Response (IR) playbook of the past-focused on log collection, manual triage, and signature matching-is catastrophically insufficient against modern APTs and ransomware groups. Today, success is defined by a single metric: MTTC (Mean Time to Containment).

The Collapse of the Attack Timeline

Attackers have weaponized Living off the Land (LotL) and Zero-Day TTPs to compress the time between Initial Access (IA) and Total Enterprise Compromise (T1562). This compression eliminates the human element’s effectiveness:

MTTC Mandate: 60 Minutes or less. Any containment action taking longer than one hour dramatically increases the probability of Domain Admin (DA) compromise and irreversible Data Exfiltration.
The Attacker’s Speed: Modern exploitation (e.g., the Windows Spooler RCE or SQL Server RPE) moves from RCE to Credential Dumping (Mimikatz) in under 30 minutes.

The CyberDudeBivash framework transforms IR from a reactive ticketing process into an Automated, Adversarial Response System designed to neutralize the attack within the initial stages of the kill chain.

Tactic 1: Validate the RCE Foothold (The Golden 5 Minutes)

The first critical hurdle is validating a P1 alert-is it a true breach or a false positive? This must be done in under five minutes to save the remaining 55 minutes for containment.

Protocol 1.1: High-Fidelity IOC Triage

The MDR (Managed Detection and Response) analyst must focus exclusively on high-fidelity IOCs (Indicators of Compromise) that indicate an RCE (Remote Code Execution) or LPE (Local Privilege Escalation) event, which traditional EDRs fail to classify correctly.

Hunt Focus: Look for the definitive Trusted Process Hijack (e.g., spoolsv.exe or sqlservr.exe spawning powershell.exe or cmd.exe).
Validation Step: The analyst must quickly check the command line arguments for signs of a fileless payload (Base64 encoding, -e or -enc flags) or direct EDR Kill Commands (taskkill /f /im). If these artifacts are present, the alert is immediately validated as Confirmed Compromise.

CONTAINMENT START: SESSIONSHIELD. The fastest alert is Impossible Travel. If the compromise originated from a Session Hijack (phishing), SessionShield detects the anomaly instantly, providing the first, most actionable P1 alert, saving the first 15 minutes of triage.

Tactic 2: Surgical Isolation-Automating the Network Quarantine

Containment must be immediate and automated. Relying on a human to manually run isolation commands is too slow and risks the attacker launching a wormable attack (e.g., EternalBlue, Log4j style) across the network.

Protocol 2.1: SOAR-Driven Host Isolation

The core goal is to isolate the infected host at two independent layers-network and endpoint-to prevent Lateral Movement (T1021).

Network Quarantine: The SOAR (Security Orchestration, Automation, and Response) playbook must automatically update the firewall (e.g., Palo Alto/Cisco/Fortinet) to block all inbound and outbound traffic from the confirmed compromised IP, isolating it to a Firewall Jail (e.g., Alibaba Cloud VPC/SEG).
Endpoint Quarantine: The EDR (Endpoint Detection and Response) API (e.g., Kaspersky EDR) must be called automatically to isolate the host from the internal network. This provides the fastest human-verified containment.

The CyberDudeBivash MTTC mandate requires this entire automated isolation sequence to complete in under 180 seconds (3 minutes).

Tactic 3: Kill the Session Token and Revoke Access (The SessionShield Mandate)

Containment is incomplete if the attacker retains authenticated access. The attacker’s most valuable asset is the Session Token or Privileged Credential.

Protocol 3.1: Session Termination and Credential Revocation

If the breach involved Session Hijacking (e.g., AiTM Phishing or 0-Day Mobile Exploit), the session must be killed immediately and the credentials invalidated.

SessionShield Kill: If the alert is sourced from SessionShield, the session token is automatically invalidated and revoked across all federated cloud environments (M365, AWS, SaaS). This is the fastest method to neutralize post-MFA bypass access.
Password/Key Rotation: If the Credential Dumping (Mimikatz) is confirmed, immediately rotate the password and revoke all session tokens for the Domain Admin (DA) account.
FIDO2 Mandate: Enforce Phish-Proof MFA (FIDO2 Hardware Keys) to prevent the attacker from simply re-using the stolen password or token.

Tactic 4: Hunt the Trust Blind Spot-Finding LotL and Trusted Process Hijacks

Once containment is confirmed, the IR Team pivots from reactive response to proactive threat hunting to find other compromised assets and the attacker’s persistence mechanisms.

Protocol 4.1: Hunting the Anomalous Execution Chain

The attacker’s LotL TTPs rely on the system trusting a valid binary (T1219). The hunt must focus on finding these abnormal chains across the entire network.

Lateral Movement Artifacts: Hunt all EDR telemetry for connections using known PsExec or WMI ports (445, 135) originating from the quarantined host prior to isolation.
Persistence Hunt: Scan the entire EDR fleet for Scheduled Tasks or Registry Run Keys that match the malware’s naming convention or reference known LotL binaries (bitsadmin, encoded `powershell`).

Lateral Movement Hunt Stub (Pre-Containment):
SELECT  FROM network_logs

WHERE

source_ip = '[QUARANTINED_IP]'

AND

dest_port IN ('445', '135') -- SMB/WMI ports

Tactic 5: Block Lateral Movement (The PsExec/WMI Kill)

The critical next step is mitigating the remaining risk of Lateral Movement from uncontained assets that the attacker may have compromised in the first 60 minutes.

Protocol 5.1: Network and Application Control Blockade

Network Segmentation: Immediately enforce Network Segmentation rules to block all traffic between Tier 1/Tier 2 segments and the Domain Controller (Tier 0). This stops the attacker’s ability to pivot laterally if they have compromised other hosts.
Application Control Kill: Verify that Application Control (WDAC/AppLocker) policies are enforced across all endpoints and servers, preventing the execution of high-risk lateral movement tools like PsExec and PsLogList.

Tactic 6: Eradication and Credential Rotation

The goal of eradication is to ensure the attacker cannot regain access using stolen persistence or credentials.

Root Cause Analysis: The IR Team must immediately determine the Initial Access Vector (IAV)-the specific 0-day, phish, or vulnerability that allowed the breach (e.g., Citrix Flaw, Windows 0-Day).
Mass Credential Rotation: Rotate all Domain Admin passwords, service account passwords, and session tokens associated with the breach. Enforce multi-factor authentication rotation for all users.

Tactic 7: Forensic Preservation and Reporting (Post-Containment)

Containment must be followed by legally sound forensic preservation and CISO-grade reporting.

Forensic Imaging: The compromised host must be forensically imaged (memory and disk) for root cause analysis and legal preservation.
MTTC Reporting: The final IR report must explicitly state the MTTC and IAV, providing the board with clear metrics on security performance and necessary architectural investment (e.g., shifting to SessionShield).

Expert FAQ & Conclusion

Q: What is the primary cause of high MTTC?

A: Manual Alert Triage. Reliance on a human analyst to manually filter low-fidelity EDR alerts and correlate telemetry is too slow. The attacker moves from Initial Access to Lateral Movement in less than an hour, guaranteeing that manual triage fails containment.

Q: How does a high-performance SOC fix alert fatigue?

A: AI-Driven Automation. The SOC uses Machine Learning to automatically cluster, score, and eliminate low-fidelity alerts, ensuring that the human analyst only reviews P1 alerts that violate Behavioral Baselines (e.g., an anomalous high-privilege shell spawning). This eliminates the noise and maximizes human output.

Q: What is the single most effective defense to achieve 60-minute MTTC?

A: Automated Containment (SessionShield). The EDR must be integrated with a SOAR platform or a tool like SessionShield to automatically isolate the host or terminate the compromised session upon validation of the highest-fidelity IOCs. Containment must be automated to defeat the speed of the attacker.

The Final Word: The fight against ransomware is a race against the clock. The CyberDudeBivash framework mandates an immediate shift to Application Control, Behavioral Threat Hunting, and Session Termination to secure your enterprise’s future.
