The Democratization of Censorship — Krebs on Security
The Democratization of Censorship — Krebs on Security https://krebsonsecurity.com/2016/09/the-democratization-of-cens... Krebs on Security In-depth security news and investigation About the Author Blog Advertising 25 Sep 16 The Democratization of Censorship John Gilmore, an American entrepreneur and civil libertarian, once famously quipped that “the Internet interprets censorship as damage and routes around it.” This notion undoubtedly rings true for those who see national governments as the principal threats to free speech. However, events of the past week have convinced me that one of the fastest-growing censorship threats on the Internet today comes not from nation- states, but from super-empowered individuals who have been quietly building extremely potent cyber weapons with transnational reach. More than 20 years after Gilmore first coined that turn of phrase, his most notable quotable has effectively been inverted — “Censorship can in fact route around the Internet.” The Internet can’t route around censorship when the censorship is all-pervasive and armed with, for all practical purposes, near-infinite reach and capacity. I call this rather unwelcome and hostile development the “The Democratization of Censorship.” Allow me to explain how I arrived at this unsettling conclusion. As many of you know, my site was taken offline for the better part of this week. The outage came in the wake of a historically large distributed denial-of-service (DDoS) attack which hurled so much junk traffic at Krebsonsecurity.com that my DDoS protection provider Akamai chose to unmoor my site from its protective harbor. Let me be clear: I do not fault Akamai for their decision. -
An Automated and Comprehensive Framework for Iot Botnet Detection and Analysis (Iot-BDA)
This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. Citation information: DOI 10.1109/ACCESS.2021.3110188, IEEE Access Digital Object Identifier 10.1109/ACCESS.2017.DOI An Automated and Comprehensive Framework for IoT Botnet Detection and Analysis (IoT-BDA) TOLIJAN TRAJANOVSKI1, NING ZHANG1 1Department of Computer Science, University of Manchester, M13 9PL UK Corresponding author: Tolijan Trajanovski (e-mail: [email protected]). ABSTRACT The proliferation of insecure Internet-connected devices gave rise to the IoT botnets which can grow very large rapidly and may perform high-impact cyber-attacks. The related studies for tackling IoT botnets are concerned with either capturing or analyzing IoT botnet samples, using honeypots and sandboxes, respectively. The lack of integration between the two implies that the samples captured by the honeypots must be manually submitted for analysis in sandboxes, introducing a delay during which a botnet may change its operation. Furthermore, the effectiveness of the proposed sandboxes is limited by the potential use of anti-analysis techniques and the inability to identify features for effective detection and identification of IoT botnets. In this paper, we propose and evaluate a novel framework, the IoT-BDA framework, for automated capturing, analysis, identification, and reporting of IoT botnets. The framework consists of honeypots integrated with a novel sandbox that supports a wider range of hardware and software configurations, and can identify indicators of compromise and attack, along with anti-analysis, persistence, and anti-forensics techniques. These features can make botnet detection and analysis, and infection remedy more effective. -
Early Detection of Mirai-Like Iot Bots in Large-Scale Networks Through Sub-Sampled Packet Traffic Analysis
Early Detection Of Mirai-Like IoT Bots In Large-Scale Networks Through Sub-Sampled Packet Traffic Analysis Ayush Kumar and Teng Joon Lim Department of Electrical and Computer Engineering, National University of Singapore, Singapore 119077 [email protected], [email protected] Abstract. The widespread adoption of Internet of Things has led to many secu- rity issues. Recently, there have been malware attacks on IoT devices, the most prominent one being that of Mirai. IoT devices such as IP cameras, DVRs and routers were compromised by the Mirai malware and later large-scale DDoS at- tacks were propagated using those infected devices (bots) in October 2016. In this research, we develop a network-based algorithm which can be used to detect IoT bots infected by Mirai or similar malware in large-scale networks (e.g. ISP network). The algorithm particularly targets bots scanning the network for vul- nerable devices since the typical scanning phase for botnets lasts for months and the bots can be detected much before they are involved in an actual attack. We analyze the unique signatures of the Mirai malware to identify its presence in an IoT device. The prospective deployment of our bot detection solution is discussed next along with the countermeasures which can be taken post detection. Further, to optimize the usage of computational resources, we use a two-dimensional (2D) packet sampling approach, wherein we sample the packets transmitted by IoT devices both across time and across the devices. Leveraging the Mirai signatures identified and the 2D packet sampling approach, a bot detection algorithm is pro- posed.
