Blockchain meetup
This document summarizes a blockchain technology workshop presented by Duru Turkoglu, PhD. The workshop covered the history and components of blockchain technology including public key cryptography, distributed systems, and applications. It discussed how blockchain provides an easy to transact and hard to modify distributed ledger through the use of cryptography and distributed consensus. Applications mentioned include cryptocurrencies, smart contracts, asset management, identity verification, and decentralized exchanges.
Defcon 22-metacortex-grifter-darkside-of-the-internet
This document provides an overview and introduction to the dark web and Tor network. It summarizes Grifter and Metacortex's background and expertise, then outlines what topics will be covered which include how to connect to and navigate Tor and the dark web safely and anonymously. Potential legal and ethical issues are also briefly discussed.
PENETRATION TESTING FROM A HOT TUB TIME MACHINE
This presentation discusses penetration testing techniques from an unconventional perspective. It advocates for intelligence gathering and footprinting before scanning or exploitation to have a more effective assessment. Specific techniques discussed include using open source intelligence gathering on internal and external systems to develop profiles and target lists. Footprinting activities within the network focus on enumeration of users, shares, services and other details to identify vulnerable systems rather than broad scanning. The presentation provides examples of exploiting old vulnerabilities in applications like Citrix and weaknesses in administration interfaces. It emphasizes continuing post-exploitation activities like privilege escalation and lateral movement within compromised systems to fully evaluate security.

Cryptography Simplified - Symmetric Key, Public Key, PKI, Digital Signature, Certification Authority, Secure Socket Layer (SSL), Secure Electronic Transaction (SET)[POSS 2019] TLS for Dummies
This document provides a high-level overview of TLS (Transport Layer Security) in 3 sentences or less:
TLS allows two parties to establish an encrypted connection by using public key cryptography for authentication during the initial handshake and then using symmetric encryption for faster encrypted data transfer. It relies on certificate authorities to validate server identities through digital signatures on their public keys. The initial handshake establishes a shared secret for deriving the symmetric encryption keys through techniques like Diffie-Hellman key exchange to provide forward secrecy if private keys are later compromised.
#OSSPARIS19 - TLS for dummies - MAXIME BESSON, Worteks
In this talk, I will explain the foundations of the TLS protocol: symmetric encryption, digital signature, PKI, and how these concepts come together to secure your network connections
Darknet
This document discusses various topics related to anonymity on darknets including:
- Ways enterprises bypass data leakage prevention including encryption and VPNs
- Differences between proxies, Tor, and VPNs and why Tor provides more anonymity
- Options for maximum anonymity hosting and WikiLeaks platforms on darknets
- Using open Wi-Fis or custom configurations as darknet exit nodes
- Digital currencies and tools like OpenTransactions that allow untraceable transactions
- Decentralized portal systems like Osiris and peer-to-peer networks for private file sharing and chat
- The relationship between encryption, anonymity, and enabling free speech
Onion routing and tor: Fundamentals and Anonymity
Onion Routing and Tor: Fundamentals and anonymity discusses anonymity on the internet and how Tor works to provide anonymity. It explains that traditional IP addresses and browser tracking can be linked to a user's identity. Tor creates circuits through multiple relay nodes to hide a user's location and communications. Key features of Tor include using volunteer-run relay nodes, protecting against traffic analysis, and enabling hidden services to host anonymous websites. While Tor enhances anonymity, it cannot prevent all timing attacks if the start and end of a user's traffic can be observed.

20180711 Metamask
MetaMask is a browser extension that allows users to access Ethereum-based decentralized applications (dapps) and manage their identities and Ethereum accounts. It acts as an Ethereum wallet and connects to the Ethereum network through Infura, an external Ethereum node provider. MetaMask stores users' private keys locally in the browser and signs transactions before sending them to the Ethereum network through Infura.
OnionBots: Subverting Privacy Infrastructure for Cyber Attacks
Over the last decade botnets survived by adopting a sequence of increasingly sophisticated strategies to evade detection and take overs, and to monetize their infrastructure. At the same time, the success of privacy infrastructures such as Tor opened the door to illegal activities, including botnets, ransomware, and a marketplace for drugs and contraband. We contend that the next waves of botnets will extensively attempt to subvert privacy infrastructure and cryptographic mechanisms. In this work we propose to preemptively investigate the design and mitigation of such botnets. We first, introduce OnionBots, what we believe will be the next generation of resilient, stealthy botnets. OnionBots use privacy infrastructures for cyber attacks by completely decoupling their operation from the infected host IP address and by carrying traffic that does not leak information about its source, destination, and nature. Such bots live symbiotically within the privacy infrastructures to evade detection,
measurement, scale estimation, observation, and in general all IP-based current mitigation techniques. Furthermore, we show that with an adequate self-healing network maintenance scheme, that is simple to implement, OnionBots can achieve a low diameter and a low degree and be robust to partitioning under node deletions. We develop a mitigation technique, called SOAP, that neutralizes the nodes of the basic OnionBots. In light of the potential of such botnets, we believe that the research community should proactively develop detection and mitigation methods to thwart OnionBots, potentially making adjustments to privacy infrastructure.
OWASP London 16 Jan-2017 - Identities Exposed by David Johansson
1) Authentication solutions like SSL/TLS client certificates and SAML SSO can compromise user privacy through design flaws. SSL/TLS does not properly validate server identity before sending client certificates, exposing them. SAML allows passive authentication requests without user consent.
2) Privacy requirements for authentication include knowing who you communicate with, when you authenticate, what information is revealed, and that only the intended recipient sees your identity. Current solutions do not always fulfill these.
3) Upcoming TLS 1.3 and careful design of client certificates and authentication requests can help address privacy issues, but flaws remain and privacy must be explicitly considered in authentication system design.
Setting Up .Onion Addresses for your Enterprise, v3.5
Onion networking provides an alternative to traditional IP networking by using self-authenticating onion addresses and circuits through the Tor network. Some key aspects of onion networking include:
1) It establishes circuits between clients and servers to transport TCP connections, similar to how IP uses frames and MAC addresses.
2) Onion addresses resolve to introduction points that introduce circuits to rendezvous points for communication, providing redundancy and avoiding single points of failure.
3) While slower than traditional networking due to additional hops, onion networking provides benefits like built-in anonymity, censorship resistance, and lack of single points of control due to its distributed nature.

Масштабируя TLS / Артём Гавриченков (Qrator Labs)
За последние годы разными специалистами и компаниями (от Google до Сноудена) был проделан колоссальный объём работы с целью популяризации протокола SSL, а позже и TLS. Дорабатывались протоколы и шифры, обнаруживались десятки уязвимостей, криптографические библиотеки форкались и проводили аудиты, правозащитные фонды выдавали сотни миллионов сертификатов "забесплатно". В конце концов, TLS явочным порядком, в обход стандарта, стал обязательным для HTTP/2-серверов. Так много сил было приложено, что просто-напросто уже невежливо всё это игнорировать.
Однако процесс внедрения TLS за это время, как это ни удивительно, не стал проще ни на йоту. Сисадмины, приступающие к развёртыванию TLS, вынуждены столкнуться с классификацией типов сертификатов, с множеством центров сертификации (которые непонятно, чем друг друга лучше) и с великим множеством дополнительных заголовков и "ручек", каждую из которых можно подёргать с непредсказуемым результатом. В результате даже крупные компании при внедрении TLS допускают ошибки той или иной степени серьёзности (включая, но не ограничиваясь масштабным даунтаймом клиентов GlobalSign), а небольшие стартапы предпочитают, вообще, обходить криптографию стороной.
За отведённые на доклад 45 минут мы постараемся дать описание каждой из пресловутых "ручек" и рекомендации по их [не]применению, а также дадим рекомендации по развёртыванию TLS на крупной инфраструктуре.

Презентация с выступления Артема Гавриченкова, CTO Qrator Labs, на конференции для разработчиков высоконагруженных систем Highload++ 2016
5.3. Undercover communications
Dennis Gamayunov discusses the history of undercover communications and encryption techniques. He describes how early systems like BBS, SMTP, and IRC lacked privacy and authentication. PGP introduced public-key cryptography for encrypting and signing messages. The Web of Trust model allows people to verify ownership of keys. However, fake keys and identities can undermine the system. The SILC protocol provides encryption for chat channels. OTR messaging provides forward secrecy, deniability, and no third-party proofs. Future work includes improving usability and expanding these techniques to group messaging.

Encryption for Everyone
The document provides an introduction to encryption basics including symmetric and asymmetric encryption. It explains how symmetric encryption works with Alice and Bob sharing a password to encrypt and decrypt messages. It also explains how asymmetric encryption works with Alice using Bob's public key to encrypt a message that only Bob can decrypt with his private key. The document recommends tools for encrypting email, disks, and browsing privately including Thunderbird, TrueCrypt, and Tor. It discusses some challenges with encryption including managing keys and speeds with Tor. The overall purpose is to educate about the importance of encryption for privacy.
c13n - Lightning Network - Greek Bitcoin Meetup.pdf
The document discusses the Lightning Network and how it enables payments and transfer of small amounts of data. It describes how Lightning Network channels work and how payments can be routed across multiple channels. It then discusses an open-source solution called c13n that allows nodes to read and write data over Lightning Network payments in an efficient and secure manner. Finally, it outlines some potential use cases for sending data and payments over Lightning Network such as messaging apps, serverless computing, and decentralized oracles.

This document provides a technical summary of Dan Kaminsky's keynote presentation. The keynote discusses three main topics:
1) Denial of service attacks and how Overflowd aims to make DDoS attacks less annoying by sharing netflow data between networks.
2) Cryptography and how JFE (Jump to Full Encryption) aims to automate TLS deployment to make encryption easier.
3) Data loss prevention and how Ratelock restricts data loss by enforcing rate limits and other policies at the serverless cloud layer to increase survivability even if complex parts are compromised.
Anon p2p slides
The document discusses anonymity and anonymous file sharing systems. It begins with definitions of anonymity and different levels of anonymity that systems aim to achieve. It then outlines several theoretical designs for anonymous systems, including proxy-based networks, mix networks, onion routing, and friend-to-friend networks. Finally, it examines several existing anonymous file sharing systems such as Mute, Ants, Mantis, and Tor that implement these theoretical designs.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Artificial Intelligence for XMLDevelopment
In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

Auntie LN
- 1. Auntie LN Your Lightning Node’s SUPER gossipy Aunt Ben Schroth & Alex Lewin
- 2. Background • Lightning nodes have a LOT to talk about. • Coordinating channels opens/closes • Advertising liquidity • Operator chit chat
- 3. Problem • Operators usually use Twitter/Telegram • Impersonations • Reputation is disconnected from the node • Lightning Nodes go down… • Gossip goes down with the node
- 4. Lightning Nodes NEED Messaging that is… • Censorship Resistant • Verifiable (signed messages) • Available when a node (client) is offline If ONLY there was a protocol like this…
- 5. Nostr – Censorship-resistant, Verifiable messaging
- 6. Nostr • Censorship Resistant • Verifiable (signed messages) • Allows multiple clients to be used
- 7. Goal
- 8. Auntie LN Your Lightning Node’s SUPER gossipy Aunt
- 9. TODO: Lightning + Nostr 1. Create Nostr Profiles for our Lightning Node 2. Verify the Authenticity of N+LN Profiles 3. Follow other Lightning Nodes
- 10. Step 1 – Create a LN Nostr Profile • Profile Announcement • Kind 0 • Node Announcement • Kind 80081
- 12. Step 2 – Verify Account Authenticity Kind 80081 • Identity Pubkey • Lightning Node • Signature • Sign(key= LNKeys, message=npub) • Network • Mainnet vs. regtest
- 13. Step 3 – Follow our Peers • Lookup Other lightning node Announcements on Nostr • Automatically follow our peers • Creates Verified list of followers
- 14. Step 3 – Send messages to peers • Lookup Other lightning node Announcements on Nostr • Automatically follow our peers
- 15. Demo
- 16. Summary • Messages backed by signatures • Available when a node (client) is offline • Alternative Secure transport Layer for Lightning
- 17. What else? What’s possible with another transport layer on Lightning?
- 18. Ideas • Write a NIP • Gossip over Nostr • Nostr Gossip Sync • It’s like RGS, except every note is signed • Better relays, automatically drops redundant gossip • Use badges to “deprecate” Nostr accounts • Help improve bandwidth over gossip (Bolt-12 FUD)
- 19. Thanks!
