What it detects

This rule detects creation of a scheduled task named Updater configured to run at user logon via schtasks and re-launch a loader DLL through rundll32, a persistence mechanism used by LATRODECTUS. The task mimics legitimate software while re-executing the implant to survive reboots. The logon trigger combined with rundll32 execution is suspicious.
