Detection

Score: 56
Range: 0 - 100
Whitelisted: false
Confidence: 100%

Signatures

Multi AV Scanner detection for submitted file
AI detected suspicious sample
Found direct / indirect Syscall (likely to bypass EDR)
Contains functionality for execution timing, often used to detect debuggers
Creates a process in suspended mode (likely to inject code)
Entry point lies outside standard sections
PE file contains sections with non-standard names
Sample execution stops while process was sleeping (likely an evasion)
Tries to resolve domain names, but no domain seems valid (expired dropper behavior)
