一种网络辅助的有效勒索软件检测方法

Toward A Network-Assisted Approach for Effective Ransomware Detection

Tianrou Xia, Yuanyi Sun, Sencun Zhu, Zeeshan Rasheed, Khurram Shafique

摘要:

勒索软件是一种使用加密机制阻止受害者正常使用计算机的恶意软件。因此,受害者无法访问他们的文件和桌面,除非他们向攻击者支付赎金。截至2019年底,勒索软件攻击已给企业和个人造成超过100亿美元的经济损失。在这项工作中,我们提出了网络辅助方法(NAA),它包含有效的本地检测和网络级检测机制,以帮助用户确定机器是否已被勒索软件感染。为了评估它的性能,我们在Docker中构建了100个容器来模拟网络场景。一个接近真实勒索软件的混合勒索软件样本被部署在刺激性感染的机器上。实验结果表明,我们的网络级检测机制分别适用于WAN和LAN环境的勒索软件检测。

英文摘要:

Ransomware is a kind of malware using cryptographic mechanisms to prevent victims from normal use of their computers. As a result, victims lose the access to their files and desktops unless they pay the ransom to the attackers. By the end of 2019, ransomware attack had caused more than 10 billion dollars of financial loss to enterprises and individuals. In this work, we propose Network-Assisted Approach (NAA), which contains effective local detection and network-level detection mechanisms, to help users determine whether a machine has been infected by ransomware. To evaluate its performance, we built 100 containers in Docker to simulate network scenarios. A hybrid ransomware sample which is close to real-world ransomware is deployed on stimulative infected machines. The experiment results show that our network-level detection mechanisms are separately applicable to WAN and LAN environments for ransomware detection.
