Level Description
watch Communicates with host for which no DNS query was performed
watch One or more of the buffers contains an embedded PE file
notice Allocates read-write-execute memory (usually to unpack itself)
notice Changes read-write memory protection to read-execute (probably to avoid detection when setting all RWX flags at the same time)
notice Creates executable files on the filesystem
notice HTTP traffic contains suspicious features which may be indicative of malware related traffic
notice One or more potentially interesting buffers were extracted
notice Performs some HTTP requests
notice Searches running processes potentially to identify processes for sandbox evasion
notice Steals private information from local Internet browsers
notice The binary likely contains encrypted or compressed data indicative of a packer
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 One or more processes crashed
info Queries for the computername
info This executable has a PDB path
