Binary visualisation for malware detection
Irina Baptista · PEARL (University of Plymouth) · 2024
It is becoming increasingly harder to protect devices against security threats; as malware is steadily evolving defence mechanisms are struggling to persevere. This study introduces a concept intended at supporting security systems using Self-Organizing Incremental Neural Network (SOINN) and binary visualization. The system converts a file to its visual representation and sends the data for classification to SOINN. Tests were done to evaluate its performance and obtain an accuracy rate, which rounds the 80% figures at the moment, and false positive and negative rates. Bytes prevalence were also analysed with malware samples having a higher amount of null bytes compared with software samples, which may be a result of hiding malicious data or functionality. The patterns created by the samples were examined; malware samples had more clustering and created different patterns across the images whereas software samples presented mostly static and constant images although exceptions were noted in both categories.
