What it detects

This rule detects creation of a scheduled task that repeatedly launches wscript.exe against a VBScript encoded file, the persistence behavior used by a Kimsuky campaign to keep its bot.vbe beacon running at short intervals. Adversaries leverage the Task Scheduler to survive reboots and maintain access while masquerading as a browser update task, making early detection critical for surfacing persistence before further payload deployment.
