Hardware Hacking Chronicles: IoT Hacking for Offence and DefenceFatih Ozavci
Enterprise companies are using consumer and IoT devices to complete (or expand) their services such as broadband, IPTV, media streaming, satellite, voice and 3G/4G services. Although the devices are owned by the service providers, subscribers have limited (or full) access to them with service agreements. In addition to that, some of consumer devices also have roles on corporate communications, environment security or employee services. Consumer devices are located at subscriber premises; therefore, the traditional security testing approach only covers backend services security, not the devices.
Consumer and IoT devices are susceptible to hardware hacking based attacks such as firmware dumping, re-flashing with a custom firmware, and getting low level access using the physical management interfaces such as SPI, JTAG and UART. Low level access obtained can be used to modify device behaviours or their initial states. This helps attackers to debug consumer devices and operator services, to find new vulnerabilities, and to obtain the device configuration which may contain credentials for the service infrastructure.
Embedded device and hardware hacking is a rising skill set for penetration testers. It is required to understand targeted attacks which may include hardware implants, modified hardware attacking their own infrastructure or compromised devices that target the human factor. Some of advanced testing examples to be discussed are preparing a custom hardware for persistent access during a red teaming exercise, preparing a compromised consumer device for human factor pen-testing, attacking TR-069 services of a provider using smart home modems or altering the security controls of a device to abuse the service.
The presentation focuses on how the existing security testing techniques should be evolved with hardware and IoT hacking, and how service providers can make their infrastructure secure for cutting-edge attacks. Essential hardware hacking information, identifying and using physical management interfaces, hardware hacking toolset, well-known hardware attacks and hardware testing procedure will be presented in a road map for consumer devices security testing. Also a security testing approach will be explained to develop new security testing services and to improve existing ones such as red teaming, human factor pen-testing and infrastructure pen-testing.
Hacking Trust Relationships Between SIP GatewaysFatih Ozavci

VoIP, or Voice over IP, converts analog voice signals to digital bits which are transmitted in packets over data networks. This allows for voice calls to be made over the internet. However, VoIP inherits vulnerabilities from both telephone and computer networks. Common attacks against VoIP systems aim to disrupt availability through DoS attacks, compromise integrity through spoofing, or violate confidentiality through eavesdropping. Proper security measures include separating VoIP and data infrastructure, using secure protocols, encryption, and VoIP-aware firewalls.

Strengthen your security posture! Getting started with IBM Z Pervasive Encryp...Tony Pearson
This session covers Pervasive Encryption on the IBM Z mainframe platform, Crypto features and concepts, and how to get started with Data Set level encryption. Presented at IBM TechU in Johannesburg, South Africa September 2019 as part of the z/OS Fast Start for Rookies track.
IBM Z Pervasive Encryption provides transparent encryption of data at rest through z/OS data set encryption. It allows encryption of data without requiring application changes by encrypting data sets at the storage level using encryption keys managed by IBM Z cryptographic hardware and software. Administrators can implement encryption by generating keys, configuring access controls and policies to associate encryption keys with data sets. The encryption protects data while allowing full access and management of the encrypted data sets.
The document discusses hardware-based security solutions from multiple companies. It describes Infineon's OPTIGATM family of security chips which provide authentication, confidentiality, and integrity for IoT applications. It also discusses Maxim's DeepCover secure authenticators and microcontrollers which incorporate techniques like secure authentication, boot, and encryption to ensure device trustworthiness and protect against threats like counterfeiting or firmware attacks. Finally, it outlines NXP's security offerings including secure elements, microcontrollers, and processors that provide solutions from the network edge to the cloud.
IBM Z Pervasive Encryption provides transparent encryption of data at rest through z/OS data set encryption without requiring application changes. Key steps to get started include generating an encryption key and key label stored in the CKDS, configuring RACF to use the key label, allowing the secure key to be used as a protected key, granting access to the key label, and associating the key label with data sets by altering the RACF DFP segment or assigning to a DFSMS data class.
This document proposes a model to enhance VoIP security. It analyzes threats to VoIP like denial of service attacks targeting the Real-time Transport Protocol (RTP). The goal is to block these threats by fully encrypting RTP packets using Advanced Encryption Standard (AES). AES is chosen because it runs faster than other algorithms and is more secure with its 128, 192, or 256-bit keys. The proposed model would encrypt the RTP stream and authentication fields like synchronous source (SSRC) to prevent attacks and unauthorized access to voice calls while maintaining efficiency and availability of VoIP.
1. Cryptography is used to provide security in electronic commerce by ensuring privacy, authenticity, and preventing forgery, alteration, eavesdropping and tracing of messages.
2. There are two main types of cryptography - symmetric which uses the same key for encryption and decryption, and asymmetric (public key) which uses different keys for encryption and decryption.
3. Common symmetric algorithms are DES and AES while RSA is an example of an asymmetric algorithm commonly used for digital signatures and encryption.

Implementing a Secure and Effective PKI on Windows Server 2012 R2Frank Lesniak
The infrastructure that deploys and manages digital certificates, known as a Public Key Infrastructure (PKI), is often the center for cryptography in an organization. It is also in service for 10+ years, which means that one must carefully consider design options before implementation. In this presentation, Frank will cover modern standards for cryptography, how they apply to a Microsoft PKI infrastructure, and share recommendations based on he has seen in the field.
The document discusses Secure Channels' patented encryption technologies for securing data, including PKMS2 and SPHERE. PKMS2 encrypts documents using multiple encryption keys and segments, making the encrypted data difficult for hackers to decrypt without all the required information. SPHERE provides similarly strong encryption across various platforms using customized encryption scripts. Secure Channels believes these technologies can effectively protect customer data from theft or hacking by rendering encrypted data unusable without the proper encryption methods and keys.
This document discusses enterprise identity and security in the cloud. It describes SecurePass, a product from GARL that provides single sign-on and strong authentication for cloud applications.

The document also discusses the security of SecurePass and GARL's datacenters and keys, and provides a case study of SecurePass being implemented for a financial institution.
Protecting application delivery without network security blind spotsThales e-Security
SSL/TLS is extensively used to protect web traffic, but the technology can also be exploited to create security blind spots. SSL/TLS encrypted tunnels can be used to hide malicious codes and other threats from network security and performance monitoring tools. To prevent possible malware propagation across networks requires decrypt/encrypt capabilities that enable careful traffic monitoring and inspection.
Don Laursen, Sr. Product Manager from F5 and Juan Asenjo, Sr. Partner Manager at Thales e-Security, explain how a security architecture using application delivery controllers (ADCs) and hardware security modules (HSMs) can ensure you can optimizes web services with traffic inspection, while safeguarding and managing the critical cryptographic keys that underpin security.

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
