Signatures
Found malware configuration
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Snort IDS alert for network traffic (e.g. based on Emerging Threat rules)
System process connects to network (likely due to code injection or exploit)
Yara detected FormBook
Allocates memory in foreign processes
Hides that the sample has been downloaded from the Internet (zone.identifier)
Injects a PE file into a foreign processes
Machine Learning detection for sample
Maps a DLL or memory area into another process
Modifies the context of a thread in another process (thread injection)
