Signatures
Contains functionality to infect the boot sector
Drops large PE files
Queries sensitive disk information (via WMI, Win32_DiskDrive, often done to detect virtual machines)
AV process strings found (often used to terminate AV products)
Binary contains a suspicious time stamp
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 check the parent process ID (often done to detect debuggers and analysis systems)
Contains functionality to communicate with device drivers
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 which may be used to detect a debugger (GetProcessHeap)
Detected potential crypto function
Drops PE files
Drops certificate files (DER)
EXE planting / hijacking vulnerabilities found
Enables debug privileges
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 dropped PE file which has not been started or loaded
Found evasive API chain (date check)
Found large amount of non-executed APIs
Found potential string decryption / allocating functions
May sleep (evasive loops) to hinder dynamic analysis
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
PE file contains executable resources (Code or Archives)
PE file contains sections with non-standard names
PE file does not import any functions
Queries disk information (often used to detect virtual machines)
Queries the volume information (name, serial number etc) of a device
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 Microsoft's Enhanced Cryptographic Provider
Uses code obfuscation techniques (call, push, ret)
Uses the system / local time for branch decision (may execute only at specific dates)
Very long cmdline option found, this is very uncommon (may be encrypted or packed)
