Level Description
watch Communicates with host for which no DNS query was performed
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 Creates a shortcut to an executable file
notice Creates executable files on the filesystem
notice Drops an executable to the user AppData folder
notice One or more potentially interesting buffers were extracted
notice Performs some HTTP requests
notice Queries for potentially installed applications
notice Queries the disk size which could be used to detect virtual machine with small fixed size or dynamic allocation
notice Uses Windows utilities for basic Windows functionality
notice Yara rule detected in process memory
info Checks amount of memory in system
info Checks if process is being debugged by a debugger
info One or more processes crashed
info Queries for the computername
info The executable contains unknown PE section names indicative of a packer (could be a false positive)
