Detection

Score: 56
Range: 0 - 100
Whitelisted: false
Confidence: 100%

Signatures

System process connects to network (likely due to code injection or exploit)
Found potential dummy code loops (likely to delay analysis)
Sample uses string decryption to hide its real strings
Contains functionality for read data from the clipboard
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to query CPU information (cpuid)
Contains functionality to read the PEB
Contains functionality to read the clipboard data
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
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
Found potential string decryption / allocating functions
HTTP GET or POST without a user agent
Internet Provider seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
Program does not show much activity (idle)
Sample execution stops while process was sleeping (likely an evasion)
Uses 32bit PE files
