Why this verdict

The malicious score of 75/100 is the fusion of 3 weighted signals:

• Process injection API combination (rule Windows_Injection_Api_Combo) - yara signal, weight 0.65, confidence 0.90
• YARA: MalwareAnalyser community pack flagged TL_Shellcode_VirtualAlloc_Exec (rule TL_Shellcode_VirtualAlloc_Exec) - engine signal, weight 0.35, confidence 0.70
• persist via registry run key (rule persist via registry run key) - capa signal, weight 0.35, confidence 0.60

Dynamic analysis

No runtime behaviour was captured for this sample, so the analysis above is static only. That is a limit of this run rather than evidence the sample does nothing.

Registry keys
