L'objectif de ces rapports est d'informer les équipes de sécurité et les entreprises des nouvelles cybermenaces et vulnérabilités, ainsi que des mesures à prendre pour améliorer la sécurité et la cyber-résilience. Nous essayons d'alerter les acteurs de la protection de la sophistication croissante des menaces et des techniques utilisées par les hackers pour usurper l'identité des utilisateurs, voler des informations et créer des perturbations. Dans ce nouveau rapport, nous relevons encore le niveau l'ampleur du périmètre de sécurité devant être défendu par d'alerte. Nos experts s'inquiètent de plus en plus de les entreprises.

  • Reporting, and General Mentions Seem to Be in Decline
    CYBER THREAT ANALYSIS Return to Normalcy: False Flags and the Decline of International Hacktivism By Insikt Group® CTA-2019-0821 CYBER THREAT ANALYSIS Groups with the trappings of hacktivism have recently dumped Russian and Iranian state security organization records online, although neither have proclaimed themselves to be hacktivists. In addition, hacktivism has taken a back seat in news reporting, and general mentions seem to be in decline. Insikt Group utilized the Recorded FutureⓇ Platform and reports of historical hacktivism events to analyze the shifting targets and players in the hacktivism space. The target audience of this research includes security practitioners whose enterprises may be targets for hacktivism. Executive Summary Hacktivism often brings to mind a loose collective of individuals globally that band together to achieve a common goal. However, Insikt Group research demonstrates that this is a misleading assumption; the hacktivist landscape has consistently included actors reacting to regional events, and has also involved states operating under the guise of hacktivism to achieve geopolitical goals. In the last 10 years, the number of large-scale, international hacking operations most commonly associated with hacktivism has risen astronomically, only to fall off just as dramatically after 2015 and 2016. This constitutes a return to normalcy, in which hacktivist groups are usually small sets of regional actors targeting specific organizations to protest regional events, or nation-state groups operating under the guise of hacktivism. Attack vectors used by hacktivist groups have remained largely consistent from 2010 to 2019, and tooling has assisted actors to conduct larger-scale attacks. However, company defenses have also become significantly better in the last decade, which has likely contributed to the decline in successful hacktivist operations.

  • Protecting Iot Devices Against Ddos Attacks
    AntibIoTic: Protecting IoT Devices Against DDoS Attacks Michele De Donno1 Nicola Dragoni1;2 Alberto Giaretta2 and Manuel Mazzara3 1 DTU Compute, Technical University of Denmark, Denmark 2 Centre for Applied Autonomous Sensor Systems, Orebro¨ University, Sweden 3 Innopolis University, Russian Federation Abstract. The 2016 is remembered as the year that showed to the world how dangerous Distributed Denial of Service attacks can be. Gauge of the disruptiveness of DDoS attacks is the number of bots involved: the bigger the botnet, the more powerful the attack. This character, along with the increasing availability of connected and insecure IoT devices, makes DDoS and IoT the perfect pair for the malware industry. In this paper we present the main idea behind AntibIoTic, a palliative solution to prevent DDoS attacks perpetrated through IoT devices. 1 The AntibIoTic Against DDoS Attacks Today, it's a matter of fact that IoT devices are extremely poorly secured and many different IoT malwares are exploiting this insecurity trend to spread glob- ally in the IoT world and build large-scale botnets later used for extremely powerful cyber-attacks [1,2], especially Distributed Denial of Service (DDoS) [3]. Therefore, the main problem that has to be solved is the low security level of the IoT cosmos, and that is where AntibIoTic comes in. What drove us in the design of AntibIoTic is the belief that the intrinsic weakness of IoT devices might be seen as the solution of the problem instead of as the problem itself. In fact, the idea is to use the vulnerability of IoT units as a means to grant their security: like an antibiotic that enters in the bloodstream and travels through human body killing bacteria without damaging human cells, AntibIoTic is a worm that infects vulnerable devices and creates a white botnet of safe systems, removing them from the clutches of other potential dangerous malwares.

  • Iot Cyber Risk: a Holistic Analysis of Cyber Risk Assessment Frameworks
    Kandasamy et al. EURASIP Journal on Information Security (2020) 2020:8 EURASIP Journal on https://doi.org/10.1186/s13635-020-00111-0 Information Security RESEARCH Open Access IoT cyber risk: a holistic analysis of cyber risk assessment frameworks, risk vectors, and risk ranking process Kamalanathan Kandasamy1* , Sethuraman Srinivas2, Krishnashree Achuthan1 and Venkat P. Rangan3 Abstract Security vulnerabilities of the modern Internet of Things (IoT) systems are unique, mainly due to the complexity and heterogeneity of the technology and data. The risks born out of these IoT systems cannot easily fit into an existing risk framework. There are many cybersecurity risk assessment approaches and frameworks that are under deployment in many governmental and commercial organizations. Extending these existing frameworks to IoT systems alone will not address the new risks that have arisen in the IoT ecosystem. This study has included a review of existing popular cyber risk assessment methodologies and their suitability to IoT systems. National Institute of Standards and Technology, Operationally Critical Threat, Asset, and Vulnerability Evaluation, Threat Assessment & Remediation Analysis, and International Standards Organization are the four main frameworks critically analyzed in this research study. IoT risks are presented and reviewed in terms of the IoT risk category and impacted industries. IoT systems in financial technology and healthcare are dealt with in detail, given their high-risk exposure. Risk vectors for IoT and the Internet of Medical Things (IoMT) are discussed in this study. A unique risk ranking method to rank and quantify IoT risk is introduced in this study. This ranking method initiates a risk assessment approach exclusively for IoT systems by quantifying IoT risk vectors, leading to effective risk mitigation strategies and techniques.

  • ERT Threat Advisory April 26, 2017
    ERT Threat Advisory Hajime – Friend or Foe? April 26, 2017 Abstract Hajime is a sophisticated, flexible and future-proof IoT botnet. It is capable of updating itself and provides the ability to extend its member bots with ‘richer’ functions, both efficiently and fast. The Hajime botnet was first reported by Sam Edwards and Ioannis Profetis from Rapidity Networks, who discovered the first occurrence of Hajime back in October, 2016, including the update blog by Ioannis (@psychotropos), and the more quantitative research by Symantec, which assesses the size of the threat. Figure 1: Message periodically displayed on the terminal by Hajime The distributed bot network used for command and control and updating is overlaid as a traceless torrent on top of the well-know public BitTorrent peer-to-peer network using dynamic info_hashes that change on a daily basis. All communications through BitTorrent are signed and encrypted using RC4 and private/public keys. The current extension module provides scan and loader services to discover and infect new victims. The efficient SYN scanner implementation scans for open ports TCP/23 (telnet) and TCP/5358 (WSDAPI). Upon discovering open Telnet ports, the extension module tries to exploit the victim using brute force shell login much the same way Mirai did. For this purpose, Hajime uses a list consisting of the 61 factory default passwords from Mirai and adds two new entries, ‘root/5up’ and ‘Admin/5up,’ which are factory defaults for Atheros wireless routers and access points. In addition, Hajime is capable of exploiting ARRIS modems using the password-of-the- day “backdoor” with the default seed as outlined here.
