Dark and Deep Webs-Liberty Or Abuse
International Journal of Cyber Warfare and Terrorism Volume 9 • Issue 2 • April-June 2019 Dark and Deep Webs-Liberty or Abuse Lev Topor, Bar Ilan University, Ramat Gan, Israel https://orcid.org/0000-0002-1836-5150 ABSTRACT While the Dark Web is the safest internet platform, it is also the most dangerous platform at the same time. While users can stay secure and almost totally anonymously, they can also be exploited by other users, hackers, cyber-criminals, and even foreign governments. The purpose of this article is to explore and discuss the tremendous benefits of anonymous networks while comparing them to the hazards and risks that are also found on those platforms. In order to open this dark portal and contribute to the discussion of cyber and politics, a comparative analysis of the dark and deep web to the commonly familiar surface web (World Wide Web) is made, aiming to find and describe both the advantages and disadvantages of the platforms. KeyWoRD Cyber, DarkNet, Information, New Politics, Web, World Wide Web INTRoDUCTIoN In June 2018, the United States Department of Justice uncovered its nationwide undercover operation in which it targeted dark web vendors. This operation resulted in 35 arrests and seizure of weapons, drugs, illegal erotica material and much more. In total, the U.S. Department of Justice seized more than 23.6$ Million.1 In that same year, as in past years, the largest dark web platform, TOR (The Onion Router),2 was sponsored almost exclusively by the U.S. government and other Western allies.3 Thus, an important and even philosophical question is derived from this situation- Who is responsible for the illegal goods and cyber-crimes? Was it the criminal[s] that committed them or was it the facilitator and developer, the U.S. -

C'est la consta- tation finale d'une première recherche sociologique dans le domaine jour- nalistique en Suisse romande. Ce GPS (Guide de Protection numérique des Sources) est le premier résultat des recommandations de cette étude. Un GPS qui ne parle pas, mais qui va droit au but en proposant des solutions concrètes pour la sécurité numérique des journalistes et de leurs sources. Il vous est proposé une approche andragogique et tactique, de manière résumée, afin que vous puissiez mettre en œuvre rapidement des mesures visant à améliorer votre sécurité numérique, tout en vous permettant d'être efficient. Même sans être journaliste d'investigation, vos informations et votre protection sont importantes. Vous n'êtes peut-être pas directement la cible, mais pouvez être le vecteur d'une attaque visant une personne dont vous avez les informations de contact.

SSL/TLS Interception Proxies and Transitive Trust Jeff Jarmoc Dell Secureworks Counter Threat Unit℠ Threat Intelligence
SSL/TLS Interception Proxies and Transitive Trust Jeff Jarmoc Dell SecureWorks Counter Threat Unit℠ Threat Intelligence Presented at Black Hat Europe – March 14, 2012. Introduction Secure Sockets Layer (SSL) [1] and its successor Transport Layer Security (TLS) [2] have become key components of the modern Internet. The privacy, integrity, and authenticity [3] [4] provided by these protocols are critical to allowing sensitive communications to occur. Without these systems, e- commerce, online banking, and business-to-business exchange of information would likely be far less frequent. Threat actors have also recognized the benefits of transport security, and they are increasingly turning to SSL to hide their activities. Advanced Persistent Threat (APT) attackers [5], botnets [6], and even commodity web attacks can leverage SSL encryption to evade detection. To counter these tactics, organizations are increasingly deploying security controls that intercept end- to-end encrypted channels. Web proxies, data loss prevention (DLP) systems, specialized threat detection solutions, and network intrusion prevention systems (NIPS) offer functionality to intercept, inspect, and filter encrypted traffic. Similar functionality is present in lawful intercept systems and solutions enabling the broad surveillance of encrypted communications by governments. Broadly classified as “SSL/TLS interception proxies,” these solutions act as a “man in the middle,” violating the end-to-end security promises of SSL. This type of interception comes at a cost. Intercepting SSL-encrypted connections sacrifices a degree of privacy and integrity for the benefit of content inspection, often at the risk of authenticity and endpoint validation. Implementers and designers of SSL interception proxies should consider these risks and understand how their systems operate in unusual circumstances. -
