How to Defend Against Password Guessing Attacks

Semperis argues AI-driven attacks are outpacing identity teams as machine identities outnumber human ones 10:1, and urges building organization-wide cyber resilience around hybrid identity protection before the next crisis.

Password spraying trades many passwords on one account for a few common ones across many, evading lockouts and monitoring. The AD Security 101 guide covers risks, detection, and defenses like MFA.

Syncing Domain Admins into Entra ID lets attackers pivot from compromised on-prem AD to the cloud, and back via password writeback. CIS and Microsoft advise keeping privileged admin accounts cloud-only.

SpecterOps argues identity risk now extends beyond Tier Zero, as attackers increasingly use legitimate credentials and trusted relationships to reach backups, regulated data, and other critical workloads.

Semperis introduces Migrator for Active Directory 2.0, an update aimed at helping organizations move Active Directory environments with confidence and greater operational control.

Password spraying tries a few common passwords across many accounts to evade lockouts, targeting VPNs, Citrix gateways, and Entra ID tenants. Defenses include MFA and passwordless; DSP can detect it.
