Network IP location
Signature (7cnts)
| Level | Description |
|---|---|
| danger | Connects to an IP address that is no longer responding to requests (legitimate services will remain up-and-running usually) |
| warning | File has been identified by 24 AntiVirus engines on VirusTotal as malicious |
| watch | Communicates with host for which no DNS query was performed |
| 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 | One or more potentially interesting buffers were extracted |
| notice | The binary likely contains encrypted or compressed data indicative of a packer |
