Whitelisted: | false |
Confidence: | 100% |
Signatures
Antivirus detection for URL or domain
Detected unpacking (changes PE section rights)
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for dropped file
Multi AV Scanner detection for submitted file
Snort IDS alert for network traffic
Yara detected FormBook
Yara detected NSISDropper
Initial sample is a PE file and has a suspicious name
Injects a PE file into a foreign processes
Machine Learning detection for dropped file
Machine Learning detection for sample
Maps a DLL or memory area into another process
Queues an APC in another process (thread injection)
Sample has a suspicious name (potential lure to open the executable)
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
Contains functionality for read data from the clipboard
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality to call native functions
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to check if a debugger is running (OutputDebugString,GetLastError)
Contains functionality to dynamically determine API calls
Contains functionality to query CPU information (cpuid)
Contains functionality to query locales information (e.g. system language)
Contains functionality to read the PEB
Contains functionality to shutdown / reboot the system
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Drops PE files
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
May sleep (evasive loops) to hinder dynamic analysis
Sample execution stops while process was sleeping (likely an evasion)
Uses 32bit PE files
Uses code obfuscation techniques (call, push, ret)
Yara signature match
