Self-Encrypting Deception: Weaknesses in the Encryption of Solid State Drives
Self-encrypting deception: weaknesses in the encryption of solid state drives Carlo Meijer Bernard van Gastel Institute for Computing and Information Sciences School of Computer Science Radboud University Nijmegen Open University of the Netherlands [email protected] and Institute for Computing and Information Sciences Radboud University Nijmegen Bernard.vanGastel@{ou.nl,ru.nl} Abstract—We have analyzed the hardware full-disk encryption full-disk encryption. Full-disk encryption software, especially of several solid state drives (SSDs) by reverse engineering their those integrated in modern operating systems, may decide to firmware. These drives were produced by three manufacturers rely solely on hardware encryption in case it detects support between 2014 and 2018, and are both internal models using the SATA and NVMe interfaces (in a M.2 or 2.5" traditional form by the storage device. In case the decision is made to rely on factor) and external models using the USB interface. hardware encryption, typically software encryption is disabled. In theory, the security guarantees offered by hardware encryp- As a primary example, BitLocker, the full-disk encryption tion are similar to or better than software implementations. In software built into Microsoft Windows, switches off software reality, we found that many models using hardware encryption encryption and completely relies on hardware encryption by have critical security weaknesses due to specification, design, and implementation issues. For many models, these security default if the drive advertises support. weaknesses allow for complete recovery of the data without Contribution. This paper evaluates both internal and external knowledge of any secret (such as the password). -
Computer and Information Security Pointer to Homework 2
Computer and Information Security (ECE560, Fall 2020, Duke Univ., Prof. Tyler Bletsch) Pointer to Homework 2 Updated 2020-09-07: Clarified SSH key format Question 0: Accessing the Homework (0 points, but necessary) Homework 2 is encrypted with three stages of encryption. You’ll need to use both your Windows VM and a new Kali Linux VM. The stages are: 1. The inner layer is a VeraCrypt encrypted disk image to be opened in Windows that contains a link to Homework 2; I explain how to find the key for this later in this document. You get to the inner layer by decrypting the outer layer. 2. The outer layer is encrypted with AES and is available for each student on the course site; the secret key is randomly generated per each student and is distributed by the Encrypted Thing Giver web app. 3. The Encrypted Thing Giver accepts an RSA public key, encrypts the random secret key using this public key. As owner of the corresponding private key, you’ll be able to decrypt it in order to obtain the AES key for the outer layer. The steps below will walk you through this crypto journey. You will need to show your work later, so keep notes! Make an SSH key pair You will need an SSH key pair. If you already created one, you can use it as-is (provided it is RSA-based, but most are). If you don’t have an SSH key pair, research how to create one with ssh-keygen. You may wish to do this on your local system, as you can set it up to let you SSH into Duke machines without a password (optional -- see Appendix A at the end of this document). -

The CEH, is the first part of a 3 part EC-Council Information Security Track which helps you master hacking technologies. You will become a hacker, but an ethical one! As the security mindset in any organization must not be limited to the silos of a certain vendor, technologies or pieces of equipment. This course was designed to provide you with the tools and techniques used by hackers and information security professionals alike to break into an organization. As we put it, “To beat a hacker, you need to think like a hacker”. This course will immerse you into the Hacker Mindset so that you will be able to defend against future attacks. It puts you in the driver’s seat of a hands-on environment with a systematic ethical hacking process. Here, you will be exposed to an entirely different way of achieving optimal information security posture in their organization; by hacking it! You will scan, test, hack and secure your own systems. You will be thought the Five Phases of Ethical Hacking and thought how you can approach your target and succeed at breaking in every time! The ve phases include Reconnaissance, Gaining Access, Enumeration, Maintaining Access, and covering your tracks. The tools and techniques in each of these five phases are provided in detail in an encyclopedic approach to help you identify when an attack has been used against your own targets. -
Fbi Fbi Flash
TLP: GREEN FBI FLASH FBI FBI Liaison Alert System #M-000045-TT The following information was obtained through FBI investigation and is provided in conjunction with the FBI’s statutory requirement to conduct victim notification as outlined in 42 USC § 10607. In furtherance of public-private partnerships, the FBI routinely advises private industry of various cyber threat indicators observed during the course of our investigations. This data is provided in order to help cyber security professionals and systems administrators to guard against the persistent malicious actions of cyber criminals. This product is released at TLP: GREEN. The information in this product is useful for the awareness of all participating organizations as well as with peers within the broader community or sector. Recipients may share this information with peers and partner organizations within their sector or community, but not via publicly accessible channels. SUMMARY The FBI is providing the following information with HIGH confidence: A group of cyber actors utilizing infrastructure located in Iran have been conducting computer network exploitation activity against public and private U.S. organizations, including Cleared Defense Contractors (CDCs), academic institutions, and energy sector companies. The actors typically utilize common computer intrusion techniques such as the use of TOR, open source reconnaissance, exploitation via SQL injection and web shells, and open source tools for further network penetration and persistence. Internet-facing infrastructures, such as web servers, are typical targets for this group. Once the actors penetrate a victim network, the actors exfiltrate network design information and legitimate user credentials for the victim network. Often times, the actors are able to harvest administrative user credentials and use the credentials to move laterally through a network. -

Analysis and Processing of Cryptographic Protocols
Analysis and Processing of Cryptographic Protocols Submitted in partial fulfilment of the requirements of the degree of Bachelor of Science (Honours) of Rhodes University Bradley Cowie Grahamstown, South Africa November 2009 Abstract The field of Information Security and the sub-field of Cryptographic Protocols are both vast and continually evolving fields. The use of cryptographic protocols as a means to provide security to web servers and services at the transport layer, by providing both en- cryption and authentication to data transfer, has become increasingly popular. However, it is noted that it is rather difficult to perform legitimate analysis, intrusion detection and debugging on data that has passed through a cryptographic protocol as it is encrypted. The aim of this thesis is to design a framework, named Project Bellerophon, that is capa- ble of decrypting traffic that has been encrypted by an arbitrary cryptographic protocol. Once the plain-text has been retrieved further analysis may take place. To aid in this an in depth investigation of the TLS protocol was undertaken. This pro- duced a detailed document considering the message structures and the related fields con- tained within these messages which are involved in the TLS handshake process. Detailed examples explaining the processes that are involved in obtaining and generating the var- ious cryptographic components were explored. A systems design was proposed, considering the role of each of the components required in order to produce an accurate decryption of traffic encrypted by a cryptographic protocol. Investigations into the accuracy and the efficiency of Project Bellerophon to decrypt specific test data were conducted. -

Draft Version
Zurich of University the at Security IT on lecture the for reading complementary as ISBN: 978-1-63081-846-3 used be can This text is extracted from the book “Cryptography 101: From Theory to Practice” that was writtentext by Rolf Oppliger and published by Artech House in June 2021 (in its Information Security and Privacy book series). This Zurich of Chapter 1 University the at Introduction Security In this chapter, we pitch the field and introduce the topicIT of the book, namely cryp- tography, at a high operating altitude and level ofon abstraction. More specifically, we elaborate on cryptology (including cryptography) in Section 1.1, address crypto- graphic systems (or cryptosystems for short) in Section 1.2, provide some historical background information in Section 1.3, andlecture outline the rest of the book in Section 1.4. The aim is to lay the basics to understand and put into proper perspective the the contents of the book. for 1.1 CRYPTOLOGY reading The term cryptology is derived from the Greek words “krypt´os,” meaning “hidden,” and “l´ogos,” meaning “word.” Consequently, the term cryptology can be paraphrased as “hidden word.” This refers to the original intent of cryptology, namely to hide the meaning of words and to protect the confidentiality and secrecy of the respective data accordingly. As will (hopefully) become clear throughout the book, this viewpoint is too narrow,complementary and the term cryptology is currently used for many other security- related purposesas and applications in addition to the protection of the confidentiality and secrecy of data. More specifically, cryptology refers to the mathematical science and field of used study that comprises cryptography and cryptanalysis. -
