针对现有恶意软件检测方法缺乏对样本特征的有效提取、过度依赖领域专家知识和运行行为监控,导致严重影响检测分类性能的问题,提出一种基于多维度动态加权alpha图像融合与特征增强的恶意软件检测方法.通过无效样本清洗与异常值处理获得标准化样本集,利用三通道图像生成与多维度动态加权alpha图像融合方法生成高质量融合图像样本.采用傀儡优化算法进行数据重构,减少因数据类不平衡对检测结果造成的影响,并对重构数据样本进行图像增强.通过基于双分支特征提取与融合通道信息表示的空间注意力增强网络,分别提取图像特征和文本特征并进行特征增强,提高特征表达能力.通过加权融合的方法将增强的图像特征与文本特征进行融合,实现恶意软件家族的检测分类.实验结果表明,本文所提方法在BIG2015数据集上的恶意软件检测分类准确率为99.72%,与现有检测方法相比提升幅度为0.22~2.50个百分点.
Existing malware detection methods suffer from inadequate extraction of sample features
excessive reliance on domain expert knowledge
and operational behavior monitoring
significantly impacting detection and classification performance. To address these issues
we propose a malware detection method based on multidimensional dynamic weighted alpha image fusion and feature enhancement. Standardized sample sets are obtained through invalid sample cleaning and outlier processing. High-quality fused image samples are then generated using a three-channel image generation and multidimensional dynamic weighted alpha image fusion method. The puppet optimization algorithm is employed for data reconstruction to mitigate the impact of data class imbalance on detection results
and image enhancement is performed on the reconstructed data samples. A spatial attention enhancement network based on dual-branch feature extraction and fusion channel information representation is used to extract and enhance image and text features
thereby improving feature representation capabilities. The enhanced image and text features are fused using a weighted fusion method to achieve malware family detection and classification. Experimental results show that the proposed method achieves a malware detection classification accuracy of 99.72% on the BIG2015 dataset
representing an improvement of 0.22~2.50 percentage points over existing detection methods.
