Hiding and obfuscation of malware to avoid antivirus detection
Rybár, Matej ; Dzurenda, Petr (oponent) ; Casanova-Marqués, Raúl (vedoucí práce)
During security assessments, it is fairly uncommon for someone to be persuaded that antivirus software does not provide total security. When a penetration tester comes across antivirus software, there are times when he or she must act quickly. For these and other reasons, a variety of methods for getting around antivirus software have been devised. Some of these obfuscation approaches aim to escape static analysis by modifying and manipulating the Portable Executable file format, which is a standardized Windows executable file format. Several types of malware change the PE file format to avoid static antivirus detection. This thesis delves into the PE file format, malware detection, and static detection of obfuscation techniques. This thesis's result is a scantime crypter Persesutor, which encrypts the input file and then decrypts and loads the encrypted file into memory after execution.
