Signatures
Multi AV Scanner detection for submitted file
Yara detected FormBook
Malicious sample detected (through community Yara rule)
Yara detected AntiVM3
Antivirus detection for URL or domain
Multi AV Scanner detection for dropped file
Sample uses process hollowing technique
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
Queues an APC in another process (thread injection)
Machine Learning detection for dropped file
Modifies the context of a thread in another process (thread injection)
C2 URLs / IPs found in malware configuration
Adds a directory exclusion to Windows Defender
Uses schtasks.exe or at.exe to add and modify task schedules
Uses 32bit PE files
Queries the volume information (name, serial number etc) of a device
Yara signature match
Antivirus or Machine Learning detection for unpacked file
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
Sample execution stops while process was sleeping (likely an evasion)
Contains functionality to call native functions
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)
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
Drops PE files
Tries to load missing DLLs
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)
