Level Description
danger Connects to IP addresses that are no longer responding to requests (legitimate services will remain up-and-running usually)
danger File has been identified by 50 AntiVirus engines on VirusTotal as malicious
danger The process powershell.exe wrote an executable file to disk which it then attempted to execute
danger Executed a process and injected code into it
watch A process attempted to delay the analysis task.
watch Allocates execute permission to another process indicative of possible code injection
watch Checks for the presence of known windows from debuggers and forensic tools
watch Checks the version of Bios
watch Collects information about installed applications
watch Communicates with host for which no DNS query was performed
watch Creates a suspicious Powershell process
watch Detects Virtual Machines through their custom firmware
watch Detects VMWare through the in instruction feature
watch Found URLs in memory pointing to an IP address rather than a domain (potentially indicative of Command & Control traffic)

watch Installs itself for autorun at Windows startup
watch Looks for the Windows Idle Time to determine the uptime
watch One or more non-whitelisted processes were created
watch One or more of the buffers contains an embedded PE file
watch Potential code injection by writing to the memory of another process
watch Resumed a suspended thread in a remote process potentially indicative of process injection
watch Used NtSetContextThread to modify a thread in a remote process indicative of process injection
notice A process created a hidden window
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 Checks adapter addresses which can be used to detect virtual network interfaces
notice Checks for the Locally Unique Identifier on the system for a suspicious privilege
notice Creates a shortcut to an executable file
notice Creates a suspicious process
notice Creates executable files on the filesystem
notice Drops a binary and executes it
notice HTTP traffic contains suspicious features which may be indicative of malware related traffic
notice Looks up the external IP address
notice One or more potentially interesting buffers were extracted
notice Performs some HTTP requests
notice Potentially malicious URLs were found in the process memory dump
notice Queries for potentially installed applications
notice Starts servers listening
notice Steals private information from local Internet browsers
notice Terminates another process
notice The binary likely contains encrypted or compressed data indicative of a packer
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 Collects information to fingerprint the system (MachineGuid
info Command line console output was observed
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)
info The file contains an unknown PE resource name possibly indicative of a packer
info This executable has a PDB path
info Tries to locate where the browsers are installed
info Uses Windows APIs to generate a cryptographic key
