AZURE & MICROSOFT 365 INCIDENT RESPONSE
Cloud Incident Response &
Microsoft 365 Breach Investigations
Cyber Centaurs provides enterprise-focused incident response and digital forensic services for organizations operating within Microsoft Azure, Entra ID, and Microsoft 365 environments. Our investigators assist organizations with Business Email Compromise, ransomware incidents, unauthorized access, cloud persistence, suspicious authentication activity, and potential data exfiltration across enterprise cloud infrastructure.
CLOUD INCIDENT RESPONSE
Cloud Threats We Investigate
Cyber Centaurs assists organizations with enterprise cloud security incidents involving Microsoft Azure, Entra ID, Microsoft 365, Exchange Online, SharePoint, OneDrive, and Teams environments. Our investigators analyze unauthorized access, suspicious authentication activity, ransomware incidents, cloud persistence mechanisms, and potential data exfiltration across Microsoft cloud infrastructure.
IDENTITY & ACCESS
Azure & Entra ID Compromise
Investigations involving unauthorized access, suspicious authentication activity, MFA abuse, impossible travel alerts, privileged escalation, conditional access manipulation, and persistence within Microsoft cloud identity infrastructure.
EMAIL & COLLABORATION
Business Email Compromise
Analysis of compromised Exchange Online environments, malicious mailbox forwarding rules, executive impersonation activity, OAuth abuse, unauthorized email access, and cloud-based financial fraud schemes.
RANSOMWARE & PERSISTENCE
Microsoft 365 Ransomware Response
Cloud-focused ransomware investigations involving OneDrive, SharePoint, Teams, Azure-hosted systems, attacker persistence mechanisms, account compromise, and enterprise-wide recovery coordination.
ENTERPRISE CLOUD INVESTIGATIONS
Azure & Microsoft 365 Incident Response
Cyber Centaurs conducts enterprise-focused cloud incident response investigations involving Microsoft Azure, Entra ID, Exchange Online, SharePoint, OneDrive, Teams, and Microsoft 365 environments. Our investigators analyze authentication activity, privileged access changes, cloud persistence mechanisms, mailbox compromise, OAuth abuse, ransomware activity, and potential data exfiltration across enterprise cloud infrastructure.
Cloud investigations often require forensic reconstruction of attacker activity across multiple Microsoft services simultaneously. Our investigative methodology combines log analysis, timeline reconstruction, identity analysis, cloud artifact preservation, and enterprise incident response procedures to identify root cause, attacker access methods, lateral movement, persistence, and organizational impact.
MICROSOFT CLOUD INVESTIGATION SERVICES
Enterprise Cloud Forensic & Incident Response Services
Cyber Centaurs provides enterprise-focused cloud forensic and incident response services involving Microsoft Azure, Entra ID, Exchange Online, SharePoint, OneDrive, Teams, and Microsoft 365 environments. Our investigations combine cloud artifact analysis, authentication review, forensic preservation, timeline reconstruction, and enterprise incident response methodologies to identify attacker activity and organizational impact.
Entra ID & Authentication Analysis
Analysis of authentication telemetry, suspicious sign-ins, MFA abuse, impossible travel alerts, privileged escalation, conditional access changes, and identity-based persistence mechanisms.
Microsoft 365 Forensics
Forensic analysis of Exchange Online, SharePoint, OneDrive, Teams, mailbox activity, cloud collaboration environments, external sharing, and unauthorized access activity.
Threat Actor Persistence Analysis
Investigation of cloud persistence mechanisms including malicious OAuth grants, rogue applications, unauthorized administrative changes, mailbox forwarding rules, and long-term attacker access.
Office 365 Business Email Compromise
Business Email Compromise (BEC) poses a significant threat to organizations operating within Microsoft 365 environments. Threat actors frequently target Exchange Online, executive email accounts, and cloud collaboration platforms using phishing campaigns, credential theft, MFA abuse, OAuth manipulation, and social engineering techniques designed to gain unauthorized access to sensitive business communications and financial processes.
Cyber Centaurs conducts enterprise-focused investigations involving compromised Microsoft 365 accounts, unauthorized mailbox access, malicious forwarding rules, suspicious authentication activity, and cloud-based persistence mechanisms. Our investigators analyze Exchange Online telemetry, Entra ID sign-in logs, mailbox audit activity, OAuth applications, administrative changes, and cloud access patterns to determine the scope and impact of the compromise.
Business Email Compromise investigations often require rapid containment and forensic reconstruction of attacker activity across multiple Microsoft cloud services simultaneously. Our incident response methodology includes account containment, authentication analysis, timeline reconstruction, cloud artifact preservation, threat actor persistence review, and identification of potential data exposure or financial fraud activity.
In enterprise environments, attackers may attempt to maintain long-term persistence through malicious OAuth grants, rogue inbox rules, unauthorized administrative access, or external forwarding configurations designed to evade traditional endpoint-based detection mechanisms. Cloud-focused forensic analysis is often necessary to identify these persistence methods and fully assess organizational exposure.
Azure & Microsoft 365 Incident Response FAQs
Answers to common questions about trade secret theft investigations.
What types of Microsoft 365 incidents does Cyber Centaurs investigate?
Cyber Centaurs investigates a wide range of Microsoft 365 and Azure security incidents including Business Email Compromise (BEC), unauthorized mailbox access, Entra ID compromise, suspicious authentication activity, MFA abuse, ransomware incidents, malicious OAuth applications, cloud persistence mechanisms, unauthorized administrative access, and potential data exfiltration involving Exchange Online, SharePoint, OneDrive, Teams, and Azure-hosted infrastructure.
Can Cyber Centaurs investigate compromised Exchange Online mailboxes?
Yes. Our investigators analyze Exchange Online mailbox activity, forwarding rules, mailbox audit logs, authentication telemetry, OAuth grants, administrative changes, suspicious inbox rules, and email access patterns to determine the scope and impact of a potential Business Email Compromise or unauthorized access incident.
What is Entra ID compromise and why is it important?
Entra ID compromise involves unauthorized access or manipulation of Microsoft cloud identity infrastructure. Threat actors may abuse privileged accounts, MFA configurations, conditional access policies, OAuth applications, or administrative permissions to maintain persistent access within an organization’s Microsoft cloud environment. Investigating identity activity is often critical to identifying root cause and attacker persistence.
Can ransomware incidents impact Microsoft 365 cloud environments?
Yes. Modern ransomware incidents may impact SharePoint, OneDrive, Teams, Exchange Online, Azure-hosted systems, and synchronized cloud environments. Threat actors may also attempt to exfiltrate cloud-based data, disable security controls, or establish persistence within Microsoft 365 infrastructure before deploying ransomware.
What Microsoft cloud artifacts are typically reviewed during an investigation?
Cloud investigations may involve analysis of Entra ID sign-in logs, Exchange Online telemetry, mailbox audit logs, conditional access activity, OAuth applications, SharePoint access logs, OneDrive activity, Teams activity, administrative changes, authentication events, and other Microsoft 365 security telemetry relevant to the incident.
Does Cyber Centaurs provide emergency incident response services?
Yes. Cyber Centaurs provides incident response services for organizations responding to active Microsoft 365 and Azure security incidents. This may include incident triage, containment guidance, forensic analysis, cloud artifact preservation, investigative reporting, ransomware response support, and enterprise incident coordination.
