Signatures

Multi AV Scanner detection for submitted file
Yara detected FormBook
Malicious sample detected (through community Yara rule)
Yara detected AntiVM3
System process connects to network (likely due to code injection or exploit)
Sample uses process hollowing technique
Tries to steal Mail credentials (via file / registry access)
Maps a DLL or memory area into another process
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
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)
Deletes itself after installation
Modifies the context of a thread in another process (thread injection)
C2 URLs / IPs found in malware configuration
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)
Internet Provider seen in connection with other malware
Detected potential crypto function
Found potential string decryption / allocating functions
Sample execution stops while process was sleeping (likely an evasion)
Contains functionality to call native functions
HTTP GET or POST without a user agent
Contains functionality for execution timing, often used to detect debuggers
Contains long sleeps (>= 3 min)
Enables debug privileges
Creates a DirectInput object (often for capturing keystrokes)
Sample file is different than original file name gathered from version info
Contains functionality to read the PEB
Uses a known web browser user agent for HTTP communication
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)
