AI detected suspicious sample
Allocates many large memory junks
Allocates memory in foreign processes
C2 URLs / IPs found in malware configuration
Contains functionality to check if a debugger is running (CheckRemoteDebuggerPresent)
Creates a thread in another existing process (thread injection)
Found direct / indirect Syscall (likely to bypass EDR)
Injects a PE file into a foreign processes
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)
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
Checks if the current process is being debugged
Contains functionality for execution timing, often used to detect debuggers

Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Extensive use of GetProcAddress (often used to hide API calls)
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
JA3 SSL client fingerprint seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
Sample execution stops while process was sleeping (likely an evasion)
Sample file is different than original file name gathered from version info
Uses 32bit PE files
Uses code obfuscation techniques (call, push, ret)
