Detects the presence of a base64-encoded signature ("UWhRC....AAYBAAAA") in the command line, which corresponds to a marshaled CREDENTIAL_TARGET_INFORMATION structure. This pattern is a strong indicator of a Kerberos coercion attack, where adversaries manipulate DNS records to spoof Service Principal Names (SPNs) and redirect authentication requests, potentially exploiting vulnerabilities like CVE-2025-33073. The rule aims to identify attempts to add spoofed SPNs to DNS records or check for their presence using commands like `nslookup`.

Detects when an attacker attempts to modify an existing scheduled task to execute a payload from suspicious locations. This technique allows attackers to bypass detection mechanisms that primarily focus on the creation of new scheduled tasks, by instead altering a legitimate task to include their malicious code.

Detects the use of the 'EnableRegion' command in AWS CloudTrail logs. This command allows an AWS account to enable additional regions. Monitoring this activity is crucial because adversaries might enable new, less-monitored regions to establish persistence, exfiltrate data, or conduct other malicious activities, potentially bypassing existing security controls that are not configured for these new regions.
