Signatures
Malicious sample detected (through community Yara rule)
Yara detected UAC Bypass using CMSTP
AI detected suspicious sample
Found direct / indirect Syscall (likely to bypass EDR)
Found hidden mapped module (file has been removed from disk)
Machine Learning detection for dropped file
Maps a DLL or memory area into another process
PE file has a writeable .text section
Switches to a custom stack to bypass stack traces
Writes to foreign memory regions
Checks for available system drives (often done to infect USB drives)
Contains functionality for read data from the clipboard
Contains functionality to call native functions
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to check if a debugger is running (OutputDebugString,GetLastError)
Contains functionality to dynamically determine API calls
Contains functionality to launch a program with higher privileges
Contains functionality to modify clipboard data
Contains functionality to open a port and listen for incoming connection (possibly a backdoor)
Contains functionality to query CPU information (cpuid)
Contains functionality to query locales information (e.g. system language)
Contains functionality to record screenshots
Contains functionality to retrieve information about pressed keystrokes
Contains functionality to shutdown / reboot the system
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Creates a process in suspended mode (likely to inject code)
Detected non-DNS traffic on DNS port
Detected potential crypto function
Dropped file seen in connection with other malware
Drops PE files
Drops files with a non-matching file extension (content does not match file extension)
Entry point lies outside standard sections
Extensive use of GetProcAddress (often used to hide API calls)
Found dropped PE file which has not been started or loaded
Found evasive API chain (may stop execution after checking a module file name)
Found large amount of non-executed APIs
Found potential string decryption / allocating functions
May sleep (evasive loops) to hinder dynamic analysis
PE file contains an invalid checksum
PE file contains executable resources (Code or Archives)
PE file contains more sections than normal
PE file contains sections with non-standard names
Queries the installation date of Windows
Queries the volume information (name, serial number etc) of a device
Tries to resolve domain names, but no domain seems valid (expired dropper behavior)
Uses code obfuscation techniques (call, push, ret)
Yara signature match
