Signatures
Antivirus detection for URL or domain
Malicious sample detected (through community Yara rule)
Snort IDS alert for network traffic
Yara detected FormBook
Yara detected GuLoader
Found direct / indirect Syscall (likely to bypass EDR)
Found suspicious powershell code related to unpacking or dynamic code loading
Maps a DLL or memory area into another process
Modifies the context of a thread in another process (thread injection)
Queues an APC in another process (thread injection)
Sigma detected: ImagingDevices Unusual Parent/Child Processes
Suspicious powershell command line found
Tries to harvest and steal browser information (history, passwords, etc)
Tries to steal Mail credentials (via file / registry access)
Very long command line found
Writes to foreign memory regions
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
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sigma detected: CurrentVersion Autorun Keys Modification
Uses code obfuscation techniques (call, push, ret)
Very long cmdline option found, this is very uncommon (may be encrypted or packed)
Yara signature match
