This rule detects command-line activity where a remote resource is downloaded via 'curl', decoded using 'base64', and then piped directly into a shell interpreter (sh, bash, or zsh). This pattern is commonly used in fileless execution or stage-one payload delivery by attackers to execute malicious scripts directly from memory.
Detects the execution of known credential harvesting tools such as Mimikatz, LaZagne, and pypykatz, or the use of their specific command-line arguments. The rule includes exclusions for common security software processes and authorized testing paths.

This rule detects attempts to disable or tamper with Microsoft Defender security features by monitoring for unauthorized modifications to specific registry keys (DisableAntiSpyware, DisableRealtimeMonitoring, or the WinDefend service start type) in conjunction with related process execution activity (e.g., PowerShell, cmd, reg, or MpCmdRun) that includes keywords associated with defender configuration changes.
Detects the use of ntdsutil.exe to create an Install From Media (IFM) set, which copies the NTDS.dit file and registry hives to a specified folder. Adversaries often use this technique to stage Active Directory credentials for exfiltration, frequently using the C:\Windows\Temp directory as a staging area. The rule includes exclusions for common legitimate system management and backup agents.

Detects network activity (DNS queries, TLS SNI, and HTTP requests) associated with identified 'ShipmentsFree' scam domains. These domains are typically used in phishing or credential harvesting campaigns to trick users into visiting fake account or tracking pages.
This rule identifies DNS queries or web requests directed toward a known list of domain names associated with the 'ShipmentsFree' family of shipping-rebate scams. These scams are typically designed to lure consumers into unknowingly signing up for recurring, undisclosed subscription services.
