Detects a suspicious correlation where an employee's phone number undergoes a SIM change or number reassignment event, immediately followed by a successful login using SMS-based MFA for the same identity. This pattern is indicative of SIM swapping/hijacking attacks, often used by threat actors like Scattered Spider to bypass SMS-based multi-factor authentication.
Detects potential OAuth device code phishing attempts by identifying sign-ins via the device code flow using applications not previously used by the specific user, especially when occurring in a burst pattern across multiple users.
Detects a coordinated attack sequence where a browser process is terminated, followed immediately by the execution of an unsigned Python interpreter from a suspicious location (temp/downloads folder), which is then followed by the installation of an unsigned browser extension. This pattern mimics ClickFix and browser-based RAT lure campaigns.
This rule detects potential social engineering attacks where an external or federated user impersonates an IT or helpdesk entity within Microsoft Teams (via chats, messages, or calls) followed shortly by an MFA registration or password reset event for the targeted user. This sequence is indicative of a vishing or phishing attack aimed at account takeover.
Detects an attempt to exploit a quote-injection vulnerability within the SharePoint ToolPane.aspx page, specifically targeting the Register directive to bypass SafeControls restrictions. This pattern is commonly used for remote code execution or unauthorized application behavior modifications by manipulating server-side parsing.
This rule detects mass phishing campaigns by identifying HTML/HTM email attachments that contain embedded URLs. It monitors for a pattern where the same sender distributes these attachments to multiple recipients, a common behavior for HTML smuggling delivery vectors where malicious payloads are constructed client-side to bypass static email gateway inspection.
Detects newly consented OAuth applications that immediately perform mass access or exfiltration of mail and file data across multiple mailboxes or drives within a short period, potentially indicating an attacker utilizing a malicious OAuth application.
Detects the granting of high-privilege permissions (e.g., mail.read, files.readwrite) to a newly registered OAuth application (less than 24 hours old), followed by high-volume API activity from that same application within one hour. This behavior is indicative of an illicit OAuth consent grant attack, where an adversary lures a user into granting permissions to a malicious application to maintain persistent access to cloud resources or perform data exfiltration.
Detects successful VPN logins that bypass multi-factor authentication (MFA) and originate from unusual ASN/IP addresses or occur during atypical hours. This behavior is indicative of potential unauthorized access using compromised credentials, consistent with threat actor patterns that exploit environments lacking mandatory MFA enforcement.
Detects a single account requesting an abnormally high number of distinct Kerberos TGS (Ticket Granting Service) tickets for SPN-mapped accounts within a 15-minute window. This behavior is indicative of Kerberoasting, where an attacker requests service tickets to perform offline brute-force cracking of service account passwords, often used for lateral movement.
