Signatures

Yara detected FormBook
Malicious sample detected (through community Yara rule)
Yara detected AntiVM3
Antivirus detection for URL or domain
Multi AV Scanner detection for domain / URL
Tries to steal Mail credentials (via file / registry access)
Maps a DLL or memory area into another process
Writes to foreign memory regions
Machine Learning detection for sample
.NET source code contains potential unpacker
Injects a PE file into a foreign processes
Queues an APC in another process (thread injection)
.NET source code contains very large array initializations
Uses runas.exe to run programs with evaluated privileges
Tries to harvest and steal browser information (history, passwords, etc)
Uses 32bit PE files
Queries the volume information (name, serial number etc) of a device
Yara signature match
May sleep (evasive loops) to hinder dynamic analysis
Uses code obfuscation techniques (call, push, ret)
Detected potential crypto function
Found potential string decryption / allocating functions
Contains functionality to call native functions
IP address seen in connection with other malware
Contains functionality for execution timing, often used to detect debuggers
Contains long sleeps (>= 3 min)
Enables debug privileges
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
Found inlined nop instructions (likely shell or obfuscated code)
Sample file is different than original file name gathered from version info
Contains functionality to read the PEB
Checks if the current process is being debugged
Found large amount of non-executed APIs
Creates a process in suspended mode (likely to inject code)
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
