了解对IoT设备的真实攻击的第一步

A First Step Towards Understanding Real-world Attacks on IoT Devices

Armin Ziaie Tabari, Xinming Ou

摘要:

随着物联网(IoT)设备的快速增长,必须主动了解它们面临的现实网络安全威胁。本文描述了我们建立蜜罐生态系统的初步努力,作为收集和分析针对物联网设备的真实攻击数据的手段。蜜罐产生有用见解的主要条件是让攻击者相信他们是人类和组织使用的真实系统。物联网设备在这方面提出了独特的挑战,由于各种各样的设备类型和物理连接性的性质。因此,我们创建了一个多阶段的方法来构建蜜罐生态系统,研究人员可以通过观察现实世界中攻击者的行为来逐渐提高低交互蜜罐在模拟物联网设备方面的复杂性。我们在内部和云中部署了蜜罐,并提供了相关的分析和审查基础设施,以确保这些蜜罐无法被轻易识别,并且看起来像是真实的系统。通过这样做,我们能够吸引越来越复杂的攻击数据。我们提出了这个蜜罐生态系统的设计和我们对攻击数据的观察。我们的数据显示,现实世界的攻击者正在明确地攻击物联网设备,一些捕获的活动似乎涉及直接的人类交互(而不是脚本化的自动活动)。我们还为物联网摄像头构建了一个低交互的蜜罐,称为Honeycamera,它向攻击者呈现看似真实的视频。这是我们朝着建立一个更全面的蜜罐生态系统迈出的第一步,这将使研究人员能够具体了解攻击者在物联网设备上的目标,以便更积极地保护它们。

英文摘要:

With the rapid growth of Internet of Things (IoT) devices, it is imperative to proactively understand the real-world cybersecurity threats posed to them. This paper describes our initial efforts towards building a honeypot ecosystem as a means to gathering and analyzing real attack data against IoT devices. A primary condition for a honeypot to yield useful insights is to let attackers believe they are real systems used by humans and organizations. IoT devices pose unique challenges in this respect, due to the large variety of device types and the physical-connectedness nature. We thus create a multiphased approach in building a honeypot ecosystem, where researchers can gradually increase a low-interaction honeypot's sophistication in emulating an IoT device by observing real-world attackers' behaviors. We deployed honeypots both on-premise and in the cloud, with associated analysis and vetting infrastructures to ensure these honeypots cannot be easily identified as such and appear to be real systems. In doing so we were able to attract increasingly sophisticated attack data. We present the design of this honeypot ecosystem and our observation on the attack data so far. Our data shows that real-world attackers are explicitly going after IoT devices, and some captured activities seem to involve direct human interaction (as opposed to scripted automatic activities). We also build a low interaction honeypot for IoT cameras, called Honeycamera, that present to attackers seemingly real videos. This is our first step towards building a more comprehensive honeypot ecosystem that will allow researchers to gain concrete understanding of what attackers are going after on IoT devices, so as to more proactively protect them.
