Yara detected AntiVM3
Yara detected FormBook
Yara detected PureLog Stealer
.NET source code contains method to dynamically call methods (often used by packers)
.NET source code contains potential unpacker
AI detected suspicious sample
Adds a directory exclusion to Windows Defender
Allocates memory in foreign processes
Found direct / indirect Syscall (likely to bypass EDR)
Initial sample is a PE file and has a suspicious name
Injects a PE file into a foreign processes
Loading BitLocker PowerShell Module
Machine Learning detection for sample
Maps a DLL or memory area into another process
Modifies the context of a thread in another process (thread injection)
Performs DNS queries to domains with low reputation
Queues an APC in another process (thread injection)
Sigma detected: Powershell Base64 Encoded MpPreference Cmdlet
Switches to a custom stack to bypass stack traces
Tries to harvest and steal browser information (history, passwords, etc)
Tries to steal Mail credentials (via file / registry access)
Writes to foreign memory regions
Allocates memory with a write watch (potentially for evading sandboxes)
Checks if the current process is being debugged
Contains functionality for execution timing, often used to detect debuggers
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality to call native functions
Contains functionality to read the PEB
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
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)
Found large amount of non-executed APIs
Found potential string decryption / allocating functions
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sample file is different than original file name gathered from version info
Sigma detected: Powershell Defender Exclusion
Uses 32bit PE files
Uses code obfuscation techniques (call, push, ret)
