danger File has been identified by 42 AntiVirus engines on VirusTotal as malicious
watch Communicates with host for which no DNS query was performed
watch Creates known Nitol/ServStart files
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 Foreign language identified in PE resource
notice One or more potentially interesting buffers were extracted
notice Queries the disk size which could be used to detect virtual machine with small fixed size or dynamic allocation
notice Repeatedly searches for a not-found process
notice Searches running processes potentially to identify processes for sandbox evasion
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 One or more processes crashed
info The executable contains unknown PE section names indicative of a packer (could be a false positive)
