Yara detected Djvu Ransomware
Yara detected Vidar stealer
Multi AV Scanner detection for dropped file
Yara detected Tofsee
Sigma detected: Copying Sensitive Files with Credential Data
Maps a DLL or memory area into another process
Found evasive API chain (may stop execution after checking mutex)
Uses netsh to modify the Windows network and firewall settings
Tries to evade analysis by execution special instruction which cause usermode exception
Machine Learning detection for sample
Allocates memory in foreign processes
May check the online IP address of the machine
Injects a PE file into a foreign processes
Sigma detected: Suspicious Svchost Process
Found evasive API chain (may stop execution after checking locale)
Contains functionality to inject code into remote 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)
Drops executables to the windows directory (C:\Windows) and starts them
Checks if the current machine is a virtual machine (disk enumeration)
Writes to foreign memory regions
.NET source code references suspicious native API functions
Found API chain indicative of debugger detection
Found evasive API chain (may stop execution after reading information in the PEB, e.g. number of processors)
Checks for kernel code integrity (NtQuerySystemInformation(CodeIntegrityInformation))
.NET source code contains method to dynamically call methods (often used by packers)
Machine Learning detection for dropped file
Modifies the windows firewall
Contains functionality to detect sleep reduction / modifications
Found evasive API chain (may stop execution after checking computer name)
Found decision node followed by non-executed suspicious APIs
Antivirus or Machine Learning detection for unpacked file
Contains functionality to query locales information (e.g. system language)
May sleep (evasive loops) to hinder dynamic analysis
Uses code obfuscation techniques (call, push, ret)
Found evasive API chain (date check)
Detected potential crypto function
Contains functionality to launch a process as a different user
Sample execution stops while process was sleeping (likely an evasion)
Found evasive API chain (may stop execution after checking a module file name)
Contains functionality to dynamically determine API calls
HTTP GET or POST without a user agent
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
Drops PE files to the windows directory (C:\Windows)
Checks if the current process is being debugged
Binary contains a suspicious time stamp
Sigma detected: Netsh Port or Application Allowed
Found large amount of non-executed APIs
Connects to a URL shortener service
May check if the current machine is a sandbox (GetTickCount - Sleep)
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
Yara signature match
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Creates files inside the system directory
PE file contains sections with non-standard names
Contains functionality to create guard pages, often used to hinder reverse engineering and debugging
Found potential string decryption / allocating functions
Yara detected Credential Stealer
Contains functionality to call native functions
Contains functionality to communicate with device drivers
Contains functionality which may be used to detect a debugger (GetProcessHeap)
PE file contains executable resources (Code or Archives)
Entry point lies outside standard sections
Enables debug privileges
Creates a DirectInput object (often for capturing keystrokes)
Extensive use of GetProcAddress (often used to hide API calls)
Contains functionality to open a port and listen for incoming connection (possibly a backdoor)
Detected TCP or UDP traffic on non-standard ports
Connects to several IPs in different countries
Uses SMTP (mail sending)
Found evaded block containing many API calls
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
Uses Microsoft's Enhanced Cryptographic Provider
