Account takeover in the SaaS & technology sector
How a account takeover attack could realistically chain together in a SaaS & technology 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.
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.
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.
MFA fatigue to Microsoft 365 takeover
With a valid password in hand, an attacker wears the user down with repeated approval prompts, registers their own authenticator for durable access, and takes over the Microsoft 365 account.
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.
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 account takeover 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.
