Found suspicious powershell code related to unpacking or dynamic code loading
Injects a PE file into a foreign processes
Joe Sandbox ML detected suspicious sample
Maps a DLL or memory area into another process
Modifies the context of a thread in another process (thread injection)
PE file contains section with special chars
PE file has nameless sections
Performs DNS queries to domains with low reputation
Powershell drops PE file
Queues an APC in another process (thread injection)
Suspicious execution chain found
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)
Binary contains a suspicious time stamp
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
Dropped file seen in connection with other malware
Drops PE files
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
PE file contains sections with non-standard names
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sigma detected: Change PowerShell Policies to an Insecure Level
Sigma detected: Use Short Name Path in Command Line
Uses code obfuscation techniques (call, push, ret)
Yara signature match
