How Russia is trying to block Tor

uk: Комп'ютерні науки

description: In December 2021, some ISPs in Russia started blocking Tor's website, along with protocol-level (DPI) and network-level (IP address) blocking to try to make it harder for people in Russia to reach the Tor network. Some months later, we're now at a steady-state where they are trying to find new IP addresses to block and we're rotating IP addresses to keep up. In this talk I'll walk through what steps the Russian censors have taken, and how we reverse engineered their attempts and changed our strategies and our software. Then we'll discuss where the arms race goes from here, what new techniques the anti-censorship world needs if we're going to stay ahead of future attacks, and what it means for the world that more and more countries are turning to network-level blocking as the solution to their political problems.

description: The hacking subculture's closest relative is that of the Darknet. Both have knowledgeable people, many of whom are highly proficient with technology and wish to remain somewhat anonymous. They are both composed of a vast amount of introverts and abide by the same first rule: “Don’t get caught." Both tend to love Sun Tzu quotes as well. What happens when the hacker mentality discussed in the Hackers Manifesto is applied to things such as OpSec on the Darknet? Over the past decade, there have been many DEF CON talks that have discussed Tor and the Darknet. None have ever come from a Darknet vendor. The approach was more academic, as opposed to economical. Having a background in IT, Infosec, and hacking, the goal is to present a unique perspective from a hacker’s point of view, as we look at how the hacker mentality applied functions in various hostile environments such as a Darknet Vendor, staff member of multiple Darknet Markets, and co-found of Dread, who then later would be a federal prisoner. Shortly after, he talks about how he was able to get himself out of federal prison 3 years early. All of which was possible through the reconnaissance of various systems and methodologies. From the anticipated linguistical analysis that the feds were making of posts on Darknet forums to how to write a motion to a federal judge from a prison cell in order to make him understand what it was like there, we will take a journey through a variety of interesting places and times from a tour guide with unparalleled experience and access. By focusing less on the basics of Tor and more on how insiders operate within it, we will uncover what it takes to navigate this ever-evolving landscape with clever OpSec. In addition to seeing what happens if you get caught. All through the perspective of the hacker spirit that refuses to submit.

description: The first critical component to any attack is an entry point. As we lock down firewalls and routers, it can be easy to overlook the network-connected physical access control systems. A study done by IBM in 2021 showed that the average cost of a physical security compromise is $3.54 million and takes an average of 223 days to identify a breach. HID Mercury is a global distributor of access control systems with more than 20 OEM partners, deployed across multiple industries and certified for use in federal and state government facilities. Trellix's Advanced Threat Research team uncovered 4 unique 0-day vulnerabilities and 4 additional undisclosed vulnerabilities leading to remote, unauthenticated code execution on multiple HID Mercury access control panels. These findings lead to full system control including the ability for an attacker to remotely manipulate door locks. During this presentation, we will briefly cover the hardware debugging process, leading to a root shell on the target. We will explore in greater depth the vulnerability discovery techniques, including emulation, fuzzing, static and dynamic reverse engineering, and a detailed walkthrough of several of the most critical vulnerabilities. We’ll address our approach to exploitation using simplistic malware we designed to control system functionality and culminate the talk with a live demo featuring full system control, unlocking doors remotely without triggering any software notification

Evil PLC Attacks - Weaponizing PLCs

uk: Комп'ютерні науки

description: These days, Programmable Logic Controllers (PLC) in an industrial network are a critical attack target, with more exploits being identified every day. But what if the PLC wasn’t the prey, but the predator? This presentation demonstrates a novel TTP called the "Evil PLC Attack", where a PLC is weaponized in a way that when an engineer is trying to configure or troubleshoot it, the engineer’s machine gets compromised. We will describe how engineers diagnose PLC issues, write code, and transfer bytecode to PLCs for execution with industrial processes in any number of critical sectors, including electric, water and wastewater, heavy industry, and automotive manufacturing. Then we will describe how we conceptualized, developed, and implemented different techniques to weaponize a PLC in order to achieve code execution on an engineer’s machine. The research resulted in working PoCs against ICS market leaders which fixed all the reported vulnerabilities and remediated the attack vector. Such vendors include Rockwell Automation, Schneider Electric, GE, B&R, Xinje, OVARRO and more.

description: The Far East and China account for two-thirds of global mobile payments in 2021. That is about $4 billion in mobile wallet transactions. Such a huge amount of money is sure to attract the attention of hackers. Have you ever wondered how safe it is to pay from a mobile device? Can a malicious app steal money from your digital wallet? To answer these questions, we researched the payment system built into Xiaomi smartphones based on MediaTek chips, which are very popular in China. As a result, we discovered vulnerabilities that allow forging payment packages or disabling the payment system directly from an unprivileged Android application. Mobile payment signatures are carried out in the Trusted Execution Environment (TEE) that remains secure on compromised devices. The attacker needs to hack the TEE in order to hack the payment. There is a lot of good research about mobile TEEs in the public domain, but no one pays attention to trusted apps written by device vendors like Xiaomi and not by chip makers, while the core of mobile payments is implemented there. In our research, we reviewed Xiaomi's TEE for security issues in order to find a way to scam WeChat Pay.

description: Apple’s Lightning connector was introduced almost 10 years ago - and under the hood it can be used for much more than just charging an iPhone: Using a proprietary protocol it can also be configured to give access to a serial-console and even expose the JTAG pins of the application processor! So far these hidden debugging features have not been very accessible, and could only be accessed using expensive and difficult to acquire "Kanzi" and "Bonobo" cables. In this talk we introduce the cheap and open-source "Tamarin Cable", bringing Lightning exploration to the masses! In this talk we are diving deep into the weeds of Apple Lightning: What’s “Tristar”, “Hydra” and “HiFive”? What’s SDQ and IDBUS? And how does it all fit together? We show how you can analyze Lightning communications, what different types of cables (such as DCSD, Kanzi & co) communicate with the iPhone, and how everything works on the hardware level. We then show how we developed the “Tamarin Cable”: An open-source, super cheap (~$5 and a sacrificed cable) Lightning explorer that supports sending custom IDBUS & SDQ commands, can access the iPhone’s serial-console, and even provides a full JTAG/SWD probe able to debug iPhones. We also show how we fuzzed Lightning to uncover new commands, and reverse engineer some Lightning details hidden in iOS itself.

description: This talk will present a study of the reliance of proprietary and open source software on Chinese vulnerability research. A difficult political environment for Chinese security researchers became acute when a law requiring vulnerability disclosure to government and banning it to all others but the affected vendor took effect in Sept. 2021. No public evaluation of this law's impact has yet been made. This talk will present results of a quantitative analysis on the changing proportion of Chinese-based disclosures to major software products from Google, Microsoft, Apple, and VMWare alongside several major open source packages. The analysis will measure change over time in response to evolving Chinese legislation, significant divergence from data on the allocation of bug bounty rewards, and notable trends in the kinds of disclosed vulnerabilities. The Chinese research community’s prowess is well known, from exploits at the Tianfu Cup to preeminent enterprise labs like Qihoo 360. However, the recent law aiming to give the Chinese government early access to the community’s discoveries—and the government’s apparent willingness to enforce it even on high-profile corporations as seen in its punishment of Alibaba—demand more thorough scrutiny. This talk will address implications for policy and the wider hacker community.

description: Windows syscalls, while increasingly trendy in red team efforts, have only been very rarely used as pure shellcode, outside of being used for Egghunters. Typically, they are used as part of red team malware, utilizing projects like SysWhispers2. An Internet search, in fact, reveals only one non-Egghunter use of syscalls, from a Windows XP-era shellcode. This is hardly surprising though, as many Windows syscalls can be extremely difficult to use and set up in as position-independent shellcode, which is a far cry from red team malware. Often syscalls require significant additional set up not required for performing equivalent actions done by calling WinAPI functions via PEB-walking. While much knowledge exists on using syscalls for red team efforts, information on writing original shellcode with syscalls so in modern x86 is sparse and lacking. Our reverse engineering efforts, however, have revealed the necessary steps to take to successfully perform syscalls in shellcode, both for Windows 7 and 10, as there are some significant differences. In this talk, we will embark upon a journey that will show the process of reverse engineering how Windows syscalls work in both Windows 7 and 10, while focusing predominately on the latter. With this necessary foundation, we will explore the process of effectively utilizing syscalls inside shellcode. We will explore the special steps that must be taken to set up syscalls – steps that may not be required to do equivalent actions with WinAPI functions. This talk will feature various demonstrations of syscalls in x86 shellcode.

description: macOS local security is shifting more and more to the iOS model, where every application is codesigned, sandboxed and needs to ask for permission to access sensitive data. New security layers have been added to make it harder for malware that has gained a foothold to compromise the user's most sensitive data. Changing the security model of something as large and established as macOS is a long process, as it requires many existing parts of the system to be re-examined. For example, creating a security boundary between applications running as the same user is a large change from the previous security model. CVE-2021-30873 is a process injection vulnerability we reported to Apple that affected all macOS applications. This was addressed in the macOS Monterey update, but completely fixing this vulnerability requires changes to all third-party applications as well. Apple has even changed the template for new applications in Xcode to assist developers with this. In this talk, we'll explain what a process injection vulnerability is and why it can have critical impact on macOS. Then, we'll explain the details of this vulnerability, including how to exploit insecure deserialization in macOS. Finally, we will explain how we exploited it to escape the macOS sandbox, elevate our privileges to root and bypass SIP.

description: Solana is a blockchain with a $37 billion dollar market cap with the security of that chain relying on the security of the smart contracts on the chain - and we found very little research on the actual execution environment of those contracts. In contrast to Ethereum, where contracts are mostly written in Solidity and then compiled to the Ethereum Virtual Machine, Solana uses a different approach: Solana contracts can be written in C, Rust, and C++, and are compiled to eBPF. Underneath the hood, Solana uses rBPF: A Rust BPF implementation with a just-in-time compiler. Given the security history of eBPF in the Linux kernel, and the lack of previous public, low-level Solana research, we decided to dig deeper: We built Solana reverse-engineering tooling and fuzzing harnesses as we slowly dug our way into the JIT - eventually discovering multiple out-of-bounds vulnerabilities.

description: Advanced Persistent Threat groups invest in developing their arsenal of exploits and malware to stay below the radar and persist on the target machines for as long as possible. We were curious if the same efforts are invested in the operation security of these campaigns. We started a journey researching active campaigns from the Middle East to the Far East including the Palestinian Authority, Turkey, and Iran, Russia, China, and North Korea. These campaigns were both state-sponsored, surveillance-targeted attacks and large-scale financially-motivated attacks. We analyzed every technology used throughout the attack chain: Windows (Go-lang/.Net/Delphi) and Android malware; both on Windows and Linux-based C2 servers. We found unbelievable mistakes which allow us to discover new advanced TTPs used by attackers, for example: bypassing iCloud two-factor authentication' and crypto wallet and NFT stealing methods. We were able to join the attackers' internal groups, view their chats, bank accounts and crypto wallets. In some cases, we were able to take down the entire campaign. We will present our latest breakthroughs from our seven-year mind-game against the sophisticated Infy threat actor who successfully ran a 15-year active campaign using the most secured opSec attack chain we've encountered. We will explain how they improved their opSec over the years and how we recently managed to monitor their activity and could even cause a large-scale misinformation counterattack. We will conclude by explaining how organizations can better defend themselves.

To bypass detection, stealthier and harder-to-detect alternatives need to come into play. In this presentation, we will take a closer look at how process-level Environment Variables can be abused for taking over legitimate applications. Taking a systemic approach, we will demonstrate that over 80 Windows-native executables are vulnerable to this special type of DLL Hijacking.

As a kid I hacked phones… cuz, well, phones were expensive! (Cardboard was an important hacking tool.) At age 6 I made a decent living cuz I could fix tube TVs. True! In roughly 1970 (thanks to NYU) we moved on to hacking Hollerith (punch) cards to avoid paying for telephone and our utilities, and of course, shenanigans. As a recording studio designer and builder, we dumpster dived for technology from AT&T. We never threw anything out and learned how to repurpose and abuse tech from the 1940s. As a rock’n’roll engineer, I learned to live with constant systems epic failures. Anything that could break would break: before a live TV event or a massive concert. Talk about lessons in Disaster Recovery and Incident Response. This talk, chock full of pictures and stories from the past, covers my hacking path as a kid then as a necessary part of survival in the entertainment industry. 1958-1981.

description: UPDATE: The slide presentation freezes from 00:27:32 until 00:29:58 due to onsite AV issues. Do you worry about responsible disclosure because they could instead exploit the time-to-patch to find you and remove you from the equation? Dead man switches exist for a reason... In this talk we present a new form of vulnerability disclosure relying on timelock encryption of content: where you encrypt a message that cannot be decrypted until a given (future) time. This notion of timelock encryption first surfaced on the Cypherpunks mailing list in 1993 by the crypto-anarchist founder, Tim May, and to date while there have been numerous attempts to tackle it, none have been deployed at scale, nor made available to be used in any useful way. This changes today: we’re releasing a free, open-source tool that achieves this goal with proper security guarantees. We rely on threshold cryptography and decentralization of trust to exploit the existing League of Entropy (that is running a distributed, public, verifiable randomness beacon network) in order to do so. We will first cover what all of these means, we will then see how these building blocks allow us to deploy a responsible disclosure system that guarantees that your report will be fully disclosed after the time-to-patch has elapsed. This system works without any further input from you, unlike the usual Twitter SHA256 commitments to a file on your computer.

description: In the 60s, engineers working in a lab at Massachusettes General Hospital in Boston invented a programming environment for use in medical contexts. This is before C, before the Unix epoch, before the concept of an electronic medical records system even existed. But if you have medical records in the US, or if you've banked in the US, its likely that this language has touched your data. Since the 1960s, this language has been used in everything from EMRs to core banking to general database needs, and even is contained in apt to this day. This is the Massachusettes General Hospital Utility Multi-Programming System. This is MUMPS. This talk covers new research into common open-source MUMPS implementations, starting with an application that relies on MUMPS: the Department of Veterans Affairs' VistA EMR. We’ll cover a short history of VistA before diving into its guts and examining MUMPS, the language that VistA was written in. Then we'll talk about 30 memory bugs discovered while fuzzing open source MUMPS implementations before returning to VistA to cover critical vulnerabilities found in credential handling and login mechanisms. We'll close by taking a step back and asking questions about how we even got here in the first place, the right moves we made, and what we can do better.

description: Electron based apps are becoming a norm these days as it allows encapsulating web applications into a desktop app which is rendered using chromium. However, if Electron apps load remote content of attackers choice either via feature or misconfiguration of Deep Link or Open redirect or XSS it would lead to Remote Code Execution on the OS. Previously, it was known that lack of certain feature flags and inefficiency to apply best practices would cause this behavior but we have identified sophisticated novel attack vectors within the core electron framework which could be leveraged to gain remote code execution on Electron apps despite all feature flags being set correctly under certain circumstances. This presentation covers the vulnerabilities found in twenty commonly used Electron applications and demonstrates Remote Code Execution within apps such as Discord, Teams(local file read), VSCode, Basecamp, Mattermost, Element, Notion, and others. The speaker's would like to thank Mohan Sri Rama Krishna Pedhapati, Application Security Auditor, Cure53 and William Bowling, Senior Software Developer, Biteable for their contributions to this presentation.

description: For decades, software vulnerabilities have remained an unsolvable security problem regardless of years of investment in various mitigations, hardening and fuzzing strategies. In the last years there have been moves to formal methods as a path toward better security. Verification and formal methods can produce rigorous arguments about the absence of the entire classes of security bugs, and are a powerful tool to build highly secure software. AdaCore/SPARK is a formally defined programming language intended for the development of high integrity software used in systems where predictable and highly reliable operation is crucial. The formal, unambiguous, definition of SPARK allows a variety of static analysis techniques to be applied, including information flow analysis, proof of absence of run-time exceptions, proof of termination, proof of functional correctness, and proof of safety and security properties. In this talk we will dive-into AdaCore/SPARK, cover the blind spots and limitations, and show real-world vulnerabilities which we met during my work and which are still possible in the formally proven software. We will also show an exploit targeting one of the previously described vulnerabilities.

Residents can not tell a news helicopter from a black hawk. Flight tracking sites remove flights as a paid service to aircraft owners and government agencies; even in the best case these sites do not receive tracking information from most military helicopters due to a Code of Federal Regulations exemption for "sensitive government mission for national defense, homeland security, intelligence or law enforcement." This makes an enormous amount of helicopter flights untraceable even for the FAA and leaves residents in the dark. What if we could help residents identify helicopters? What if we could crowd source helicopter tracking? What if we could collect images to identify helicopters using computer vision? What if we could make aircraft radio as accessible as reading a map? What if we could make spotting helicopters a game that appeals to the competitive spirit of Washingtonians? And what if we could do all of this... on Twitter?

description: "Scientific research or data science need rapid experimentation and building intuitions from data. Yet, in academia or in the industry, the code must live on to be useful for future enquiries or in production. Always experimenting yet writing production-ready robust code may seem a conundrum. However it shares a lot with agile or extreme programming techniques. It is an interesting test bed of programming practices." "I will explore simple, and less simple, practices that I have encountered in my research for fast turn around and consolidation of code. I will discuss how these considerations led to the design of scikit-learn, that enables easy machine learning, yet is used in production. Finally, I will mention some scikit-learn gems, new or forgotten."

Python is Weird

Python hides a lot of peculiarities very well, but for the sake of this talk we will try to uncover them. I will be explaining how the whole process of tokenizing - parsing - ast creation - bytecode works and will use odd Python code to show the internals. Do you think `++4;` is valid Python? Or how about `0jif.1else-2`? There's no spaces in it. Go figure! "Edge cases" will help us understand the inner workings of Python. We will be looking into how modules, classes and instances are really just fancy dictionaries and how importing is really nothing else than storing a module into a dictionary (`sys.modules`). There's a lot of things we can learn from diving deep into the details of our beloved languages."

RevDB, a Reverse Debugger

uk: Комп'ютерні науки

description: "RevDB is an experimental "reverse debugger" for Python, similar to UndoDB-GDB or LL for C. You run your program once, in "record" mode, producing a log file; once you get buggy behavior, you start the reverse-debugger on the log file. It gives an (improved) pdb-like experience, but it is replaying your program exactly as it ran---all input/outputs are replayed from the log file instead of being redone. The main point is that you can then go backward as well as forward in time: from a situation that looks really buggy you can go back and discover how it came to be. You also get "watchpoints", which are very useful to find when things change. Watchpoints work both forward and backward. I will show on small examples how you can use it, and also give an idea about how it works. It is based on PyPy, not CPython, so you need to ensure your program works on PyPy in the first place (but chances are that it does)."

description: "Config management in larger applications can become quite complex: Information needs to be loaded from different sources like environment variables, config files and command line arguments, the loaded data needs to be validated to ensure all expected information is present and in the correct format and then distributed to different locations in the codebase. This holds true especially in data science projects, having rich model and training configurations. To simplify this process, we developed and open-sourced ConfZ, a config management library for Python based on pydantic. It easily allows to load config values from heterogeneous sources, validates them and makes them accessible as Python dataclass-like objects with full IDE support. It furthermore supports in common use cases like having multiple environments, lazy loading and unit testing. Within two months, we already reached more than 100 stars on GitHub. In this talk, we show how ConfZ is used and how it compares to other config management solutions. We then dig into the pythonic details and see how meta classes drive the internals of the library."

description: "As a DevOps engineer, when you write Python code, do you also write tests? If you're like the majority of the folks out there, chances are you don't. Why would you? It's usually just a script, even if it gets longer over time and starts feeling like Bash. – Deep inside you know that writing tests would be needed. It's the prerequisite for test automation, the foundation of release automation. But heck, who cares? It would be cumbersome to do. You write scripts for your automation tasks – Python makes it easy to get started – and you have noticed that they get hard to maintain when they grow and accumulate logic? Sometimes you split up a large script into several files, but that feels like spaghetti code? Several plates of spaghetti. This talk explains why it makes sense to stop hacking glue code and start developing serious CLI applications, test-driven, with automated tests. Even if you have some experience with writing tests, it's not immediately obvious how to get started. You'll get to know the cli-test-helpers package and see a hands-on demonstration of developing a CLI application from scratch, TDD-style. We'll scratch the surface of some popular CLI frameworks (argparse, click, docopt), and you'll take home working code samples that will help you refuse the temptation of writing code without tests, in future.

description: Computation is ubiquitous across all areas of science, policy, and daily life in a diverse array of applications. Modeling is one such application that has become critical to a wide range of research and policy issues, spanning multiple scientific disciplines. These computational tools allow researchers to study and forecast complex, dynamic interactions of multiple social and natural processes in ways not possible with more traditional means. While scientists share the results of model-based research with policymakers and others in respected, peer-reviewed journals and conferences, following widely understood and accepted scientific norms, equivalent practices for documenting, evaluating, and sharing the code of the models that produced such research findings have lagged behind. This especially critical when this technology is urgently needed to help humanity is confront the challenge of successfully and sustainably managing a planetary socioecological system, in which a highly complex, telecoupled, global society is tightly coupled with diverse biophysical systems. A grass-roots initiative of the international modeling community, over the past eight years, led to the formation of the Open Modeling Foundation (OMF). The OMF is a global alliance of modeling organizations that coordinates and administers a common, community developed body of standards and best practices among diverse communities of modeling scientists. As an international open science community, the OMF works to enable the next generation modeling of human and natural systems.

In addition to his work as a researcher, he coordinates the European project InBestSoil (Monetary valuation of soil ecosystem services and creation of initiatives to invest in soil health: setting a framework for the inclusion of soil health in business and in the policymaking process), within the framework of the Mission Soil of the Horizon Europe program. InBestSoil (https://cordis.europa.eu/project/id/101091099/es) is a research and innovation action funded under the call: Incentives and business models for soil health. The idea behind this project is to translate into monetary values the interventions that we make to improve the soil quality, as well as the ecosystem services provided by healthy soils. The project is going to be developed around nine case studies spread across Europe: three living labs and six lighthouses. For the economic valuation, we will combine Life Cycle Assessment (LCA) and Cost Benefit Analysis (CBA). On the one hand, the LCA is going to focus on the positive and negative impacts of producing healthy soils, i.e., the interventions used to improve soils. The results of the LCA will be one of the inputs to the CBA. For the CBA, the costs and benefits derived from ecosystem services will also be considered. And this valuation of ecosystem services will be made considering market values calculated directly; and non-market values, which will be determined through preference methods (contingent valuation or choice experiment) and benefit transfer methodologies.

description: Today European scale research projects are not only limited to collaborative scientific advancements. They require joint cross-border, interdisciplinary development and operationalization of results following the principles of open source and FAIR data. The ADO Project (Alpine Drought Observatory, https://www.alpine-space.org/projects/ado/) is led by Eurac Research and relies on collaboration within research institutes of six alpine countries for creating a scientifically sound operational drought information web platform aiding decision makers on an alpine to regional level in managing water resources and drought impacts. The ADO web platform (https://ado.eurac.edu/) feeds on big data satellite and climate archives on the input side and shows curated drought information through an interactive web platform for stakeholders and decision makers. The presentation will guide through the concepts, operational maintenance and update and show the web platform in action.

description: As a PhD candidate and research within OpenGeoHub Foundation, Carmelo focuses on data science projects such as GeoHarmonizer and the MOOD H2020 project. During the 2023 MOOD Summer School, he gave a session on covariates data for SDM. The goal of this lecture was to learn how to select and explore the variables to include in predictive models. By the end of the lecture, the students learned how to search for additional datasets in literature and open repositories, how to select the proper variables based on the topic of their research and how to conduct exploratory analysis of messy datasets. They finally learned how to prepare a dataset ready for modeling by including information coming from their response variable (treated in the previous lecture) and the predictive variables.

description: Well-understanding indoor climate to ensure the comfort and well-being of the housed animals is important. Evaluation of the indoor climate for a naturally ventilated pig barn equipped with an indoor housing area and an outdoor exercise area is a challenge. Therefore, to accurately evaluate indoor climate for the special pig housing system, an open-source software OpenFOAM as a CFD simulation tool was used in this study. First, to ensure an accurate CFD model for the simulation of airflow pattern, different mesh sizes and 5 turbulence models (k-ɛ, RNG k-ɛ, realizable k-ɛ, k-ω, k-ω SST) were tested. Then, seven cases with different wind directions (0°, 30°,?150°, 180°) perpendicular to the sidewalls and two cases of pig barns with/without an exercise yard were simulated and assessed by indoor airflow pattern and ventilation rate. It is a preliminary study, and the results contribute to a better understanding of the airflow pattern inside the naturally ventilated pig barn with an outdoor exercise yard in relation to different wind directions and barn geometries.

description: Zwischen den 1960er und 80er Jahren, zwischen Mauerbau und Mauerfall, erlebte das östliche Niedersachsen – die Region Braunschweig, Wolfsburg, Helmstedt, Salzgitter, Peine, Wolfenbüttel – einen tiefgreifenden Wandel. Architektur und Städtebau der "Späten Moderne" hinterließen etliche baukünstlerisch herausragende Objekte, aber auch eine große Zahl von Bauten, denen heute wenig Wertschätzung entgegengebracht wird. PD Dr.-Ing Ulrich Knufinke vom Niedersächsischen Landesamt für Denkmalpflege unternimmt eine "Besichtigung" dieser Epoche und Region. Anlass ist das Erscheinen eines Wegweisers der Braunschweigischen Landschaft e.V., der zu den bekannten, aber auch zu den vielen bislang unentdeckten Zeugnissen der spätmodernen Architektur zwischen Harz und Heide führt und spezifische denkmalpflegerische Fragen dieser Epoche umreißt.
