What’s new in Active Directory (2025): Availability, supportability & security enhancements
September 5, 2025
Active Directory 2025 security, availability, and supportability are now the defining pillars of enterprise identity resilience.
Sneak-peek
Here we talk about the latest changes that improve three pillars—availability (staying online), supportability (seeing and fixing issues fast), and security (withstanding and recovering from attacks). Together they reshape how you design, operate, and…
What is an N-Day Exploit? Definition, Mechanism & Security Risks
September 3, 2025
An n-day exploit targets a vulnerability after public disclosure, weaponizing the delay between a vendor’s fix and enterprise patch adoption.
Definition (snippet-friendly):
An n-day exploit is a cyberattack that targets a known software vulnerability after it has been publicly disclosed.
Attackers leverage the period when patches or mitigations exist but are not yet widely applied.

Storm-0501 Exploits Microsoft Entra ID to Wipe and Ransom Azure Data
September 1, 2025
In August 2025, Microsoft warned that Storm-0501, a financially motivated ransomware group, is abusing Microsoft Entra ID and hybrid Active Directory synchronization accounts to seize control of entire cloud environments. Victims reported that attackers exfiltrated Azure data, deleted backups, and issued ransom demands over Microsoft Teams. For IT admins and security engineers, this marks a…
Monitoring lateral movement paths in AD

Monitoring Lateral Movement Paths in Active Directory
Lateral movement is what happens after an attacker (or rogue insider) gets an initial foothold: they pivot from one
machine/account to another until they reach high-value targets like file servers, application tiers, and ultimately Domain Admin
or Tier-0 assets. In Active Directory (AD), lateral movement succeeds not…
Using canary tokens in AD to detect breaches
August 29, 2025
Canary tokens are deliberate “tripwires”: objects, credentials, or breadcrumbs that should never be touched in normal operations.
When an attacker (or an automated tool) interacts with them, you get a high-signal alert that something is wrong—often early, before full domain compromise.
This guide focuses on practical canary patterns that work well in Active Directory…
Tracking use of default domain admin credentials

Tracking Use of Default Domain Admin Credentials (Built-in Administrator & Domain Admins)
“Default Domain Admin credentials” usually means the built-in domain Administrator account
(the well-known account with SID ending in -500) and/or “obvious” privileged identities
(members of Domain Admins) that attackers love to target because they’re…
How to deploy deception techniques in AD
August 29, 2025
Deploying Deception Techniques in Active Directory (AD): A Practical Defender’s Playbook Deception in Active Directory is about placing high-signal, low-risk traps where real attackers naturally go—so you detect early, confirm intent faster, and reduce time-to-contain. Done well, deception doesn’t replace monitoring; it amplifies it by turning attacker curiosity into reliable alerts.
