Signatures
Antivirus detection for URL or domain
Multi AV Scanner detection for submitted file
AI detected suspicious sample
Found suspicious powershell code related to unpacking or dynamic code loading
Loading BitLocker PowerShell Module
Opens network shares
Powershell drops PE file
Queries sensitive network adapter information (via WMI, Win32_NetworkAdapter, often done to detect virtual machines)
Binary contains a suspicious time stamp
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to query CPU information (cpuid)
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Drops PE files
Enables debug privileges
Extensive use of GetProcAddress (often used to hide API calls)
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
Found dropped PE file which has not been started or loaded
Found evasive API chain checking for process token information
Found large amount of non-executed APIs
Found potential string decryption / allocating functions
IP address seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
One or more processes crash
PE file contains executable resources (Code or Archives)
PE file contains sections with non-standard names
PE file does not import any functions
Queries sensitive BIOS Information (via WMI, Win32_Bios & Win32_BaseBoard, often done to detect virtual machines)
Queries sensitive Operating System Information (via WMI, Win32_ComputerSystem, often done to detect virtual machines)
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sigma detected: Change PowerShell Policies to an Insecure Level
Sigma detected: CurrentVersion Autorun Keys Modification
Sigma detected: Potential Binary Or Script Dropper Via PowerShell
Uses Microsoft's Enhanced Cryptographic Provider
Uses code obfuscation techniques (call, push, ret)
