danger File has been identified by 52 AntiVirus engines on VirusTotal as malicious
danger Executed a process and injected code into it
watch Allocates execute permission to another process indicative of possible code injection
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 Network activity contains more than one unique useragent
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 Allocates read-write-execute memory (usually to unpack itself)
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 Potentially malicious URLs were found in the process memory dump
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 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
