Signatures
Early bird code injection technique detected
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
System process connects to network (likely due to code injection or exploit)
VBScript performs obfuscated calls to suspicious functions
Yara detected GuLoader
Yara detected Powershell download and execute
Yara detected RHADAMANTHYS Stealer
AI detected suspicious sample
Found suspicious powershell code related to unpacking or dynamic code loading
Hides threads from debuggers
Queries sensitive disk information (via WMI, Win32_DiskDrive, often done to detect virtual machines)
Queues an APC in another process (thread injection)
Sigma detected: WScript or CScript Dropper
Suspicious execution chain found
Suspicious powershell command line found
Switches to a custom stack to bypass stack traces
Writes to foreign memory regions
Wscript starts Powershell (via cmd or directly)
Checks if the current process is being debugged
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality to open a port and listen for incoming connection (possibly a backdoor)
Contains functionality to read the PEB
Contains long sleeps (>= 3 min)
Creates a DirectInput object (often for capturing keystrokes)
Creates a process in suspended mode (likely to inject code)
Detected TCP or UDP traffic on non-standard ports
Detected potential crypto function
Found WSH timer for Javascript or VBS script (likely evasive script)
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
IP address seen in connection with other malware
Installs a raw input device (often for capturing keystrokes)
Internet Provider seen in connection with other malware
JA3 SSL client fingerprint seen in connection with other malware
Java / VBScript file with very long strings (likely obfuscated code)
May sleep (evasive loops) to hinder dynamic analysis
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sigma detected: Msiexec Initiated Connection
Sigma detected: Uncommon Svchost Parent Process
Sigma detected: WSF/JSE/JS/VBA/VBE File Execution Via Cscript/Wscript
Suricata IDS alerts with low severity for network traffic
Uses a known web browser user agent for HTTP communication
Uses code obfuscation techniques (call, push, ret)
Very long cmdline option found, this is very uncommon (may be encrypted or packed)
Very long command line found
Yara detected Keylogger Generic
Yara signature match
