Multi AV Scanner detection for dropped file
Multi AV Scanner detection for submitted file
Snort IDS alert for network traffic
System process connects to network (likely due to code injection or exploit)
Yara detected SmokeLoader
AI detected suspicious sample
C2 URLs / IPs found in malware configuration
Checks for kernel code integrity (NtQuerySystemInformation(CodeIntegrityInformation))
Checks if browser processes are running
Checks if the current machine is a virtual machine (disk enumeration)
Contains functionality to compare user and computer (likely to detect sandboxes)
Creates a thread in another existing process (thread injection)
Deletes itself after installation
Found evasive API chain (may stop execution after checking mutex)
Hides that the sample has been downloaded from the Internet (zone.identifier)
Injects code into the Windows Explorer (explorer.exe)
Machine Learning detection for dropped file
Machine Learning detection for sample
Maps a DLL or memory area into another process
PE file has a writeable .text section
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Tries to harvest and steal Putty / WinSCP information (sessions, passwords, etc)
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 to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality to call native functions
Contains functionality to check the parent process ID (often done to detect debuggers and analysis systems)
Contains functionality to dynamically determine API calls
Contains functionality to enumerate process and check for explorer.exe or svchost.exe (often used for thread injection)
Contains functionality to query CPU information (cpuid)
Contains functionality to retrieve information about pressed keystrokes
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Detected potential crypto function
Drops PE files
Drops files with a non-matching file extension (content does not match file extension)
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 potential string decryption / allocating functions
Internet Provider seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
One or more processes crash
PE file does not import any functions
Sample execution stops while process was sleeping (likely an evasion)
Sigma detected: Execution of Suspicious File Type Extension
Uses 32bit PE files
Uses Microsoft's Enhanced Cryptographic Provider
Uses a known web browser user agent for HTTP communication
Uses code obfuscation techniques (call, push, ret)

SmokeLoader | The SmokeLoader family is a generic backdoor with a range of capabilities which depend on the modules included in any given build of the malware. The malware is delivered in a variety of ways and is broadly associated with criminal activity. The malware frequently tries to hide its C2 activity by generating requests to legitimate sites such as microsoft.com, bing.com, adobe.com, and others. Typically the actual Download returns an HTTP 404 but still contains data in the Response Body. |
