watch Communicates with host for which no DNS query was performed
watch Found URLs in memory pointing to an IP address rather than a domain (potentially indicative of Command & Control traffic)
watch Resumed a suspended thread in a remote process potentially indicative of process injection
notice Allocates read-write-execute memory (usually to unpack itself)
notice An application raised an exception which may be indicative of an exploit crash
notice Changes read-write memory protection to read-execute (probably to avoid detection when setting all RWX flags at the same time)
notice Performs some HTTP requests
notice Potentially malicious URLs were found in the process memory dump
notice Uses Windows utilities for basic Windows functionality
notice Yara rule detected in process memory
info One or more processes crashed
