Signatures

Antivirus / Scanner detection for submitted sample
Multi AV Scanner detection for submitted file
AI detected suspicious sample
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality to query CPU information (cpuid)
Creates a process in suspended mode (likely to inject code)
Detected TCP or UDP traffic on non-standard ports
Detected potential crypto function
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sigma detected: Use Short Name Path in Command Line
Suricata IDS alerts with low severity for network traffic
Uses cacls to modify the permissions of files
Uses code obfuscation techniques (call, push, ret)
