XWorm LATAM Campaign Activity
This rule detects activities associated with the XWorm LATAM campaign. It identifies network indicators such as specific C2 domains (jholycf100.ddns.com.br, voulerlivros.com.br, res.cloudinary.com), a specific IP address (152.249.17.145), and a destination port (7000). It also looks for the abuse of CasPol.exe making outbound connections to the identified C2 infrastructure. Furthermore, the rule detects PowerShell processes spawned by WMI (WmiPrvSE.exe) that attempt to fetch content from Cloudinary and load assemblies in memory, indicating potential in-memory execution. Finally, it includes a specific SHA256 file hash (7befeacf0b3480fb675d0cab7767b5b9697edc9d0e05982025a06ead0054afd5) associated with the campaign.
