Data theft in the Professional services sector
How a data theft attack could realistically chain together in a Professional services organisation, from initial access to business impact — and exactly what you should test to break the chain.
Microsoft 365 account to sensitive data
A phished Microsoft 365 identity is turned into durable access, used to discover where sensitive data lives in SharePoint and Teams, and finally to quietly extract it — all without dropping malware.
Web application flaw to cloud credentials
A flaw in an internet-facing custom application is used to reach the workload's identity, harvest cloud credentials, and pivot into the wider cloud account where production data lives.
Entra ID guest account to privileged access
An over-permissioned external guest identity is used to enumerate the tenant, abuse excessive directory rights and escalate toward privileged roles and the resources they unlock.
Supplier account to internal network
A compromised supplier's access is used to enter the organisation through a trusted connection, then to move from the supplier's limited footprint toward internal systems and data.
SaaS administrator compromise
A phished SaaS administrator identity is used to weaken tenant security settings, establish persistence via integrations, and access or export the customer and business data the platform holds.
Google Workspace account to data theft
A phished Google Workspace identity is turned into durable access through a third-party app grant, then used to search Drive and Gmail for sensitive material and export it.
Azure managed identity to subscription control
A compromised Azure workload is used to assume its managed identity, whose over-broad role assignments are escalated toward control of the subscription and the data it holds.
Phishing to executive communications compromise
A targeted lure compromises an executive or assistant mailbox, which is quietly monitored to harvest sensitive correspondence and impersonate leadership for further reach.
SaaS API token to data theft
A leaked API token for a business SaaS platform is used to access its API directly, enumerate what the token can reach, and export data at scale — bypassing the login and its MFA entirely.
Identity provider compromise to federated access
An attacker who reaches the single sign-on identity provider abuses its trust to grant themselves access across every federated application at once — turning one identity system into keys to the whole estate.
Why chaining matters here
A scanner might flag each weakness in this environment in isolation. What determines whether data theft is actually achievable is whether those weaknesses — together with identities, trust relationships and gaps in monitoring — can be linked into a working path. That is what a red-team engagement validates, and what these chains are designed to help you scope.
