This rule detects potential ransomware activity by monitoring for a high volume (more than 10) of file creation or renaming events within a short timeframe (30 minutes) initiated by a process named 'htspnew.exe'. It excludes common system and temporary directories to reduce noise, focusing on suspicious file modifications that might indicate bulk encryption or mass file manipulation.

Detects network communication with known malicious domains and IP addresses, as well as the presence of known malicious file hashes on the system. The rule correlates network connection events, file creation events, and process creation events against predefined lists of C2 infrastructure and malware indicators.

This rule detects the creation of cron jobs in /etc/cron.d/ that are associated with known miner file names (e.g., redis-miner, xminer). It explicitly looks for instances where the initiating process or its parent process is associated with Redis, suggesting a compromise or exploitation of a Redis service to establish persistence for a crypto miner.

This rule detects network connections from monitored devices to known cryptomining pool IP addresses and domain names. It monitors DeviceNetworkEvents for indicators of compromise (IOCs) associated with cryptomining activities, identifying potential resource hijacking on internal endpoints.
