Signatures
Yara detected RedLine Stealer
Detected unpacking (overwrites its own PE header)
Yara detected SmokeLoader
System process connects to network (likely due to code injection or exploit)
Detected unpacking (changes PE section rights)
Antivirus detection for URL or domain
Yara detected GuLoader
Found malware configuration
Multi AV Scanner detection for submitted file
Benign windows process drops PE files
Multi AV Scanner detection for domain / URL
Multi AV Scanner detection for dropped file
Maps a DLL or memory area into another process
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Uses known network protocols on non-standard ports
Machine Learning detection for sample
Injects a PE file into a foreign processes
Deletes itself after installation
Creates a thread in another existing process (thread injection)
Hides that the sample has been downloaded from the Internet (zone.identifier)
Found many strings related to Crypto-Wallets (likely being stolen)
Checks if the current machine is a virtual machine (disk enumeration)
.NET source code references suspicious native API functions
Checks for kernel code integrity (NtQuerySystemInformation(CodeIntegrityInformation))
.NET source code contains method to dynamically call methods (often used by packers)
Queries sensitive disk information (via WMI, Win32_DiskDrive, often done to detect virtual machines)
Machine Learning detection for dropped file
C2 URLs / IPs found in malware configuration
May sleep (evasive loops) to hinder dynamic analysis
Uses code obfuscation techniques (call, push, ret)
Detected potential crypto function
Sample execution stops while process was sleeping (likely an evasion)
JA3 SSL client fingerprint seen in connection with other malware
Contains functionality to dynamically determine API calls
Downloads executable code via HTTP
Contains long sleeps (>= 3 min)
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
Drops files with a non-matching file extension (content does not match file extension)
PE file contains strange resources
Drops PE files
Tries to load missing DLLs
Contains functionality to read the PEB
Uses a known web browser user agent for HTTP communication
Checks if the current process is being debugged
Binary contains a suspicious time stamp
Creates a process in suspended mode (likely to inject code)
Uses 32bit PE files
Queries the volume information (name, serial number etc) of a device
Internet Provider seen in connection with other malware
Yara detected Credential Stealer
Contains functionality to call native functions
IP address seen in connection with other malware
Contains functionality for execution timing, often used to detect debuggers
Enables debug privileges
Creates a DirectInput object (often for capturing keystrokes)
AV process strings found (often used to terminate AV products)
PE file contains an invalid checksum
Detected TCP or UDP traffic on non-standard ports
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
