Fidye yazılımı saldırılarının karmaşıklığı arttıkça, geleneksel yöntemlerin tehditleri tespit etme ve önleme konusunda yetersiz kalmaya başlaması sebebiyle modern kötü amaçlı yazılım tespit yöntemleri kullanılmaya başlanmıştır. Bunlar davranış temelli algılama, sistem temelli algılama, kaynak temelli algılama, bağlantı temelli algılama ve entropi temelli fidye yazılımı algılamadır. Bu çalışmada Binalayze AIR ve Binalayze Tactical yazılımları yardımıyla tespit edilen kötü amaçlı yazılımların entropi değerlerini değerlendirerek, entropi temelli kötü amaçlı yazılım tespit yönteminin fidye yazılımı saldırılarını tespit etme ve önlemedeki etkinliği değerlendirilmeye çalışılmıştır. 41477 kötü amaçlı yazılımın değerlendirildiği kapsamlı saha çalışmamızın sonuçlarında da ortaya konduğu üzere, entropi temelli kötü amaçlı yazılım tespit yönteminin kolay uygulanabilir olması, diğer yöntemlerle entegre olarak kullanılabilmesi ve hızlı sonuç vermesi gibi avantajları olmasına rağmen tek başına kullanıldığında yüksek oranda yanlış pozitif ve yanlış negatif sonuçlar verebilmektedir. Entropi temelli yöntem, hibrit modellerle birlikte kullanılmadığı sürece tek başına güvenilir değildir. Etkili siber güvenlik savunmaları sağlamak için daha gelişmiş ve bütünsel yaklaşımların benimsenmesi gerekmektedir.

Reliability of Entropy-based Malware Detection as a Single Method in Preventing Ransomware Attacks

Öz

As the complexity of ransomware attacks increases, traditional detection methodologies are often insufficient for detecting and preventing threats. Therefore, modern malware detection methods are used. These are the behavior-, system-, resource-, connection- and entropy-based ransomware detection methods. In this study, we evaluated the effectiveness of an entropy-based malware detection method in detecting ransomware attacks by evaluating the entropy values of malware detected using Binalayze AIR and Binalayze Tactical software. As revealed in the results of our comprehensive field study in which 41477 malware were evaluated, although the entropy-based malware detection method has advantages in that it is easily applicable, can be integrated with other methods, and provides fast results, it can give high rates of false-positive and false-negative results when used alone. The entropy-based method is unreliable unless it is used with hybrid models. More advanced and holistic approaches must be adopted for effective cybersecurity defense.
