Powerful surveillance software for everyday use tune in our calls, text messages, real-time GPS location or encrypted messaging apps like WhatsApp. These capabilities can afford dramatic powers & control over an individual's everyday life. Surveillance apps for private purposes are routinely linked to identity theft, physical injuries, sexual harassment, extortion & child abuse, among others. Some are marketed as ways for employers to monitor the movements of their workers, or for parents to check electronically on the whereabouts of their children. Others promise to help you to reveal infidelity. However, the same malicious software with an aim to monitor & control a targeted person is being also sold to the governments.
Where do the tech community, the police, & the policymakers stand on the issue of deployment of surveillance apps for private purposes?
How are such products used by the governments?
Is the usage of such software legal?
And, lastly, how do you safeguard yourself against an attack?

The first one developed a piece of malware, named DNSpionage, targeting several government agencies in the Middle East, as well as an airline. During the research process for DNSpionage, we also discovered an effort to redirect DNSs from the targets and discovered some registered SSL certificates for them. We identified multiple countries targeted by this redirection. On 22 January 2019, the US DHS published a directive concerning this attack vector. In this presentation, we will present the timeline for these events and their technical details. The second actor is behind the campaign we named “Sea Turtle”. This actor is more advanced and more aggressive than the previous one. They do not hesitate to target directly registrars and one registry. The talk will present the 2 actors and the methodology used to target the victims.

Deserialization is the process of converting a data stream to an object instance. At the end of 2015, the Java community was taken by storm by deserialization vulnerabilities using a weakness from the library Commons-Collection. The event highlighted how many applications used unsafe deserialization. At the time, Jenkins, WebLogic, WebSphere and JBoss used the same vulnerable code pattern. Two years later, researchers turned to the .NET ecosystem and discovered that many serialization libraries were vulnerable to similar attacks. In 2018, vulnerabilities were found notably in SharePoint (Workflows API), PHP-BB (using a new PHP vector) and many more. Hundreds of CVEs were recorded for the same year proving that deserialization is still an active threat for modern web applications. Developers and pentesters can't ignore this risk because, in most cases, it leads to remote code execution.
This 3-hour workshop will go through the basics of exploiting such vulnerabilities in multiple languages including Java, .NET and PHP. After the theory, participants will have access to vulnerable applications specially designed for the workshop. The objective for the participants will be to exploit applications using the presented methods. Step-by-step instructions and tools will be provided to the participants. Additionally, participants will gain knowledge and skills to build gadgets in dedicated exercises.
Intermediate
Beginners will be able to do the first part of the workshop (exploitation with YSoSerial) but have a hard time doing the custom gadget exercise.

Wajam Internet Technologies was a start-up founded in 2009 in Montreal. Their eponym product was a "social search engine" solution. Its promise was to get Internet search results based on your relations on social networks. Wajam was free to install. To start monetizing the software, they started adding ads to search results. Gradually, Wajam began acting more and more like adware: they used pay-per-install platforms to distribute the application, obfuscation and even kernel drivers (rootkit) to hide their malicious behavior from users and security products. According to D&B Hoovers, the net benefits made by the company were estimated to $CAD 4.2M in 2013.
After being investigated, the Privacy Commissioner of Canada reported in 2017 that Wajam Internet Technologies breaches the Personal Information Protection and Electronic Documents Act (PIPEDA). This did not stop their activities: they quickly sold all assets to a virtual company based in Hong Kong to avoid Canadian authorities. In late-2018, new samples targeting both Windows and macOS emerged and were quickly linked to Wajam.
This talk will detail the technical findings of these recent variants and how they are related to the previous techniques used by Wajam. The technical evolution of the samples collected over the years will be mapped with the unique history of the company. From this timeline, it will be highlighted that behaviours that could be considered as malicious are much older than one may realize, and the self-protection methods used by the software are increasing in complexity and sophistication.

Disassembly is a well-known problem in the reverse-engineering community, but designing and building a disassembler engine able to deal with architectures like MIPS, ARM/ARM64 and x86/x64 at the same time, compiled by classic compilers or custom obfuscators, is a long and difficult road.
While translating individual instructions to their corresponding assembly representations is doable, producing a correct and complete representation of a whole executable is indeed another story. This adventure includes dealing with numerous compilers’ peculiarities, such as switch-case constructions, position-independent code and control-flow optimizations, while struggling with theoretically intractable questions, such as code and data distinction.
In this talk, we would like to dig into the internals of our own disassembler engine, which is part of JEB reverse-engineering platform. This component produces an assembly-like representation of a whole binary object, in particular for MIPS, ARM/ARM64 and x86/x64 executables, and has been developed fully in-house over the last three years.
During this presentation, we will describe in particular:
the design choices behind our disassembler engine. We will explain how we developed most of the logic in a generic way, while trying to keep architecture-specific parts contained, and how the disassembler employs different strategies depending of the architecture and the identified compiler.
the use of a so-called “advanced” analysis pass, based on a custom intermediate representation (IR), which allows us to compute possible runtime values in the same way on all architectures. We will explain in particular the design of our IR, and the way we translated native instructions to the IR.
the implementation of signatures on machine code, such that classic statically linked libraries are automatically identified. We will dig into the problems that the generation, storage and matching of such signatures brought.
the various techniques and tests we developed to assess the disassembler correctness.
Finally, dealing with several (quite different) architectures forced us to very often reassess our assumptions on what machine code is supposed to look like. Throughout this presentation, we will describe the mistakes and wrong assumptions we made, in the hope that it will be useful to fellow security researchers dealing with machine code.

WebAssembly (WASM) is a new binary format currently supported by all major browsers (Firefox, Chrome, WebKit /Safari and Microsoft Edge) and executed inside JS scripts. It is already used for malicious purposes like Cryptojacking and can be found inside some web-browsers addons.
In this workshop, I will first introduce WebAssembly concepts and why it’s consider as a “game changer for the web”. Secondly, I will expose different techniques (Static/Dynamic analysis) and tools (Octopus, Wasabi, ...) to perform a WebAssembly module analysis. Finally, we will hands-on with basic examples (crackmes) and go throws some real-life cryptominer and web-browsers plugins using WebAssembly module. Along the talk, I will only used open source tools.

Thousands of organizations have already adopted the idea of inviting good-faith hacking to hack into their systems via vulnerability disclosure, bug bounty and next-gen pen test programs. Even so, the risk of prosecution under anti-hacking laws still casts a cloud over the hackers who are trying to help, and many programs haven't removed this risk by including Safe Harbor language within their program policies. It's not intentional -- the simple truth is that the market has progressed so rapidly that most have implemented crowdsourced security programs without realizing this issue, nor do they know how to how to fix it. Bilateral Safe Harbor language enables program owners to not only provide a strong incentive for good-faith hackers in terms of explicit legal protection, but also to outline exactly what constitutes "good-faith" hacking for their organization, and leave legal protections against malicious hackers intact.
This talk provides an overview of Safe Harbor in the context of good-faith hacking and introduces a current effort to create a standardized, open-source, easily readable legal boilerplate for disclosure program owners all around the world to use.
As application security gained in popularity and maturity, attackers and researchers have turned to more creative methods for exploiting web applications. In 2017, security researcher Omer Gil introduced the Web Cache Deception attack. This attack, while trivial to understand and leverage, showed the potential of attacking caching mechanisms instead of targeting the application itself in order to extract sensitive information. In 2018, GoSecure introduced a new class of attack known as Edge Side Include Injections, exploiting a design flaw introduced nearly two decades ago in popular caching servers and cache providing solutions. Again in 2018, James Kettle released his research on Web Cache Poisoning, which leverages unkeyed input to reflect arbitrary data in an HTTP response in order to get a cross-site-scripting payload cached across users.
The findings from this research show the obvious flaws we failed to identify in caching specifications for so long. This talk aims to be a precautionary tale for the next time you need to implement a web caching solution by providing a practical overview of caching attacks in web applications. We'll look at attacks targeting both modern and legacy web applications, how to detect these design oversights and leverage them, and more importantly how to mitigate them.

User-centric security and privacy conversations are based around best-practices or a binary of what to do and what not to do. This has been detrimental to practical conversations around user security and privacy. In the context of digital sexual expression, users are typically shamed and told not to engage in those activities without providing an alternative.
Harm reduction provides an alternative framework that can be used. At its core, harm reduction is based around making risky behaviors safer. It has successfully been used for public health programming around drug use and sexual activities.
This talk will introduce harm reduction as a framework for user-centric security and privacy and walk through an example based on research around gay dating apps. Through this case study, I will discuss some of the ways that taking a harm reduction approach shifted security expectations and priorities to recommend practical features that had major implications for user safety.
Security and privacy harm reduction is still a developing conversation. This talk is aimed at a wide audience to introduce harm reduction as a framework with the goal of improving the methods and practices around user-centric security and privacy.

Erica also works on EFF's net neutrality project, writing technical filings and opinion pieces and organizing technologists from the networking industry to speak up for technical accuracy in policy decisions.
We shape our world with stories, and with these stories we define our universe. Despite all the advancements in technology, humanity's ability to accurately predict future events is regressing. Why is this happening? Short answer: the narrative.
A strong narrative creates context for the seemingly impossible – red teamers can blend in with network traffic, social engineers can walk into restricted buildings, and security professionals can overcome the imposter syndrome. During this talk, I'll define behavioral heuristic fundamentals and use personal stories to illustrate the impact narration has on adversary simulation activities, developing a career in security, and my perception of myself.

Workshops are first-come first-serve and have a participant limit.
This workshop is an introduction to Return Oriented Programming. The workshop aims to be fitting for people with varying background, as it starts easy and with detailed explanation on hands-on exercises but increases difficulty over time. The workshop is a good fit for attendees who already know about buffer overflows but want to go further. For them it's a perfect next step which will take their exploiting skills to the next level!
The basic example of exploiting a buffer overflow is pushing shellcode on the stack and jumping to it. This is successful when there are no security mechanisms. But how can we get a shell if the stack is not executable? Return Oriented Programming (ROP) is a neat technique to defeat this protection.
In this workshop, we will step up the game by turning on the NX-bit and using ROP to exploit the buffer overflow anyway. The basic idea of ROP is to use code snippets that are already in the binary. This way, we can put the shellcode together like we would tinker a blackmailing letter from old newsletters, putting the fitting pieces one after another, until we get the payload we want.
We will work on Linux (x86-64), get to know the libc, and debug the process. By observing the stack and registers, we will see how choosing code snippets that end with a ‘return’ (ROP-gagdets) plays out.
The workshop contains 3 exercises of different stages.
The first stage will give an easy start to get to know the environment and commands. This exercise is done together, to get a quick and efficient example on how to interact with the tools. The second exercise will allow the attendees to explore the exploit on their own, with my assistance when needed.
The 3rd stage will be solving the challenge with ASLR turned on (without PIE). This will get us a longer ROP-Chain, we will have a look on other useful segments like the Global Offset Table and how to use this for exploitation. Also, the combination of using ROP on 64 Bit with ASLR turned on can score you some points in CTFs.
I will provide a VM with the binaries and my presentation on it. Using a common system is the easiest way to get the same offsets in our address calculation. I will also provide instructions to set up the VM in case the attendees want to set up their own VM.

There is no legal obligation to ship secure code, and most companies survive data breaches without real consequences. Companies all too often decide that security best practices aren't worth the extra resources. And corporate responsibility if often thought of as an obligation to shareholders. But as customers, employees andcommunity members, don't we want to see more than that?
This talk explores the obligations that companies have to their user base, and the ways that community expectations can lead to stronger security practices. We'll begin with an exploration of the nature of community and corporate obligation, drawing from traditional philosophical approaches across culture. Some examples we'll explore:
Even young, scrappy crypto companies will not launch until they have a pen test, referred to as an "audit report." There is no legislation requiring this, but it's become part of the culture. What can we learn from this, to potentially encourage adoption of similar practices in the broader startup community? (Is that even desirable?)
It's accepted that social media companies minimize the use of full time moderators, because that would be expensive. But this comes at a real psychological cost to users. Companies like Facebook and Twitter failed to stop the spread of a violent viral video on March 14th and 15th, despite requests from authorities in New Zealand and complaints from sensitive customers worldwide. What were Facebook and Twitter's obligations here? How does cost factor in?
This talk aims to give a thoughtful overview of the security landscape and current events, with the aim of leaving the audience with a better framework for evaluating corporate obligations and advocating for improved security practices.

Video conferencing systems are increasingly used to talk about critical issues in corporate environments, but there are very few attacks and tools dedicated to them. Cisco Meeting Server or CMS is a software used to make video conferences, which allows users to connect to meetings through different clients or via WebRTC with a browser.
During a series of tests conducted with this software, we detected that remotely and without authentication it is possible to list the active conferences on a CMS server and obtain a large amount of information for each conference such as the name of the conference, ID, video address, passcode protection and more. After our report, in November 2018 Cisco published a security advisory associated with this vulnerability with CVE-2018-15446. We also detect that remotely and without authentication, in some cases it is possible to perform a bruteforce attack of the passcode in the conferences that have one, to obtain this numeric code and access the corresponding videoconference.
Based on this research, we developed two open source tools in Python: m33tfinder and m33tbreak that allow to automate this attack, knowing only the URL of the CMS server.An attacker using our tools could identify the URL of the CMS of a certain company, obtain the valid conferences, identify the conferences that discuss critical issues such as budgets, directive committees, board meetings and join the meetings as a guest. That way the attacker could access the critical information discussed in them or record them, using only a web browser.
In our talk, we will see the overall security of videoconferencing systems, the story of how we discovered the vulnerability, how to identify the Cisco Meeting Servers exposed on the Internet, the technique used to obtain information about the conferences and perform the bruteforce attack, a demo of the tools to carry out an attack on a CMS and the countermeasures we can take to protect ourselves from these attacks in case of administering or using this or another videoconferencing system.

This workshop is expanded upon by Introduction to appliance reverse engineering. Workshops are first-come first-serve and have a participant limit.
The classic firmware update procedure was to download the latest version from the manufacturer then upload it to your device which allowed easy access for inspection. In today's IOT devices, firmware may update itself directly using HTTPS. This allows for timely security updates but removes the end user access to the binary.
Fortunately, there are ways to extract a firmware from the flash chip on a circuit board using common protocols. In this workshop, we will learn:
10 kits will be provided at the workshop to experiment with, come early.
Each kit contains:
TPLink WDR3600 or WDR4300 (similar models with UART, SPI and JTAG interfaces available)Adapter c232hm-ddhsl-0 or bus pirate recommended. Other similar adapters will also work.Linux computer recommended although other operating systems may be used if the attendee know how to install and operate the suggested software or similar software on his favorite operating system.
Among the myriad of programming languages which have been defined overthe last five decades, some provide memory safety (e.g. Java, Rust)but are often inapplicable to low-end embedded systems with 32-bitmicrocontrollers and a few dozen kilobytes of RAM at best:
Both RAM and ROM (Flash) sizes are severely constrained; a bulky runtime systems cannot be accommodated, and even a "normal-sized" stack is not an option.
Small embedded systems do not have an operating system at all, and do not provide features on which many language runtimes rely on, e.g. a MMU to trap dereferencing of NULL pointers, or multithreading.
Many microcontrollers use custom or reduced CPU versions that existing code generators do not support, forcing the use of a vendor-provided C compiler.
This talk describes T1, a novel programming language that tries toaddress these issues. It is an evolution of T0, the Forth-like languagewhich is already successfully used in BearSSL for managing the SSL/TLShandshake and for verifying X.509 certificate chains.
Thomas Pornin is a cryptographer, author of the BearSSL library. He works as a consultant for NCC Group, as part of the Cryptography Services team.
Significant advances in quantum computing capabilities would spell theend of the public key infrastructure as we know it. Shor's algorithm,a quantum algorithm for efficiently solving the discrete logarithmproblem, means that computational problems whose hardness is thefoundation of public key crypto are easy to compute on a quantumcomputer.
All is not lost for asymmetric cryptography. Quantum key distribution(QKD) allow the establishment of a shared secret key under the soleassumption of an authenticated channel. Post-quantum cryptographylooks instead to replace the hardness assumptions on which public-keycryptosystems are built.
This talk will review computational assumptions relied upon bytraditional cryptography and why they fail the coming of the quantumcomputer. We will review proposed alternatives that are part of NIST'spost-quantum cryptography standardization's efforts.

Server-side Linux malware is a real threat now. Unfortunately, unlike for itsWindows counterpart, most system administrators are inadequately trained ordon't have enough time allocated to analyze and understandthe threats that their infrastructures are facing. This tutorial aims atcreating an environment where Linux professionals have the opportunity tostudy such threats safe and in a time-effective fashion.
In this introductory tutorial you will learn to fight real-world Linux malwarethat targets server environments. Attendees will have to find maliciousprocesses and concealed backdoors in a compromised Web server.
In order to make the tutorial accessible for a range of skill levels severalexamples of malware will be used with increasing layers of complexity — fromscripts to ELF binaries with varying degrees of obfuscation. Additionally, asis common in Capture-The-Flag information security competitions, flags will behidden throughout the environment for attendees to find.

Among the novelties developed for Bitcoin, one can find a very interesting scheme for asymmetric key derivation introduced in BIP32 (“Bitcoin Improvement Proposals”). The principle is to be able to derive child keys in a deterministic way from their parents’ keys.
This is a “feature” which is already available in straight ECC, since one can simply exploit the distributivity of the scalar multiplication over the elliptic curve addition law.
No need for any blockchain, and I'm thus explaining in this talk some basic EC maths, before explaining how this key derivation works, and I'll finally be showcasing a few examples.

An endpoint security strategy can incorporate many layers of technology and security controls. Solution components such as Endpoint protection platform (EPP), Endpoint detection and response (EDR), Application whitelisting and more are utilized to provide protection and response to specific threats that affect endpoints. When dealing with endpoints that reside in cloud infrastructure new risks are introduced that cannot be adequately monitored with traditional endpoint solutions alone.
This presentation will go over general best practices for securing a cloud environment (AWS/Azure) including the use of EDR on instances as well as methods that can be employed to conduct threat hunting exercises against collected data. We will also discuss what additional investigative details and context can be gained through correlation of endpoint and cloud events.

When on the hunt for new malware, the digital connection to the physical world can often be overlooked. We’re constantly reminded in the news of political struggles and physical warfare, with adversaries targeting each other through sanctions or military action. However, a large portion of these real world decisions are driven by digital espionage, which is evolving at an exponential rate - even ‘traditional’ digital espionage like desktop malware and phishing campaigns are being supplemented by state sponsored mobile surveillance-ware. This talk will highlight 4 real world mobile espionage campaigns tied to political and physical conflicts, allowing attendees to get a broader understanding of the targeting and intelligence collection techniques of global actors, as well as tool development to evade (repeated) detection, and hopefully use these characteristics to enhance threat hunting efforts.

The RDP protocol has a wide variety of interesting features, yet no tool supported the complexity of the RDP protocol for information security purposes. Inspired by RDPY, we created PyRDP, an open-source general-purpose RDP man-in-the-middle tool. This presentation will cover use cases for PyRDP in malware research and pentesting.
First, we added new features to our project to help with malware research. One crucial feature is the ability to rewrite the username and password sent to the server. This is used to allow access to the target RDP server to anyone using any credentials, which maximizes hostile interactions. Our tool also saves full RDP sessions to disk as well as clipboard content and files transferred during the sessions. Having session replays allows us to extract tactics, techniques and procedures (TTPs) from malicious actors. By using our tool and pointing it to a real RDP server, we created a fully interactive honeypot and caught a malware actor in the act.
We will do a demonstration of these features and show replays of the malware actor we caught.
Second, in a corporate environment, RDP is oftentimes used by high-privilege user accounts to manage Active Directory, servers, users' workstations and more. Using RDP is so ingrained in day-to-day tasks that users stop thinking about the potential consequences of connecting to random machines.
We will present PyRDP's use cases in pentesting engagements and propose an approach to compromising high-privileged accounts. A man-in-the-middle in an RDP context can be used to capture credentials, but it can do more. Instead of reusing the credentials to launch another connection, attackers can interactively hijack the existing connection and disguise their actions as coming from the victim. Additionnally, it can lead to the partial compromise of the client machine by abusing features such as drive redirection to enumerate and download sensitive files. PyRDP can also be used to challenge the incident response process by attracting the incident response team to a machine and capturing their credentials as they connect. Finally, the replay files produced by PyRDP can be used to demonstrate the impact of compromise to high-level executives.
The talk will cover these attack scenarios in depth and will end with a short demo of the open-source tool and its capabilities.

Quantum computers pose a grave threat to the cryptography we use today. Sure, they might not be built for another decade, but today’s secrets are nonetheless at risk: indeed, many adversaries have the capabilities to record encrypted traffic today and decrypt it later. In this talk, I give an overview of post-quantum cryptography (PQC), quantum-safe alternatives developed to alleviate this problem. I talk about the NIST PQC competition that will lead to new standards to replace RSA and ECC, I present our prototype integrations into real-life protocols and applications (such as TLS, SSH, and VPN), and our experiments on a variety of devices (from IoT, to cloud, to HSM). I discuss the Open Quantum Safe project for PQC development, and related open-source forks of OpenSSL, OpenSSH, and OpenVPN that can be used to experiment with PQC today. I'll present a demo of a post-quantum TLS 1.3 connection. Finally, I explain the practicality of PQC, and how to start experimenting with it to defend your applications and services against the looming quantum threat.

64-bit shellcoding and introduction to buffer overflow exploitation on Linux is a 3 hour workshop which is essentially divided into 3 parts:
Introduction to 64-bit architecture in order to get familiar with registers, stack, calling conventions described in the Intel 64 (x86-64) architecture manual and the most common assembly instructions and syscalls which we will later use to write our shellcodes.
Shellcoding where we try different techniques to write the shellcode and of course you gonna get to greet the shellcoding world with your own Hello World shellcode in addition to reverse shell which we will use later on in part 3
Introduction to buffer overflows, so you can put your newly received know-how about stack into practise right away. Shellcode without being used is a wasted shellcode! Part 3 ends with a buffer overflow challenge where your goal is to use your reverse shellcode to get a connection back to your machine.
Keywords:
Participants are expected to either build their own Ubuntu 16.04 VM-s per given instructions or simply download the ready made machine provided for them and import it to Virtualbox.
If you want to prepare your machine yourself then get Ubuntu 16.04.6 Xenial 64-bit VM from: osboxes.org/ubuntu/ and follow the instructions.If you prefer a ready made machine which you can just import to Virtualbox then download the .OVA file from: preview.tinyurl.com/yxnkek9j
It is an introductory course so no knowledge on assembly, shellcoding, buffer overflows is needed, but of course helpful if they do. However, students should be able to user Virtualbox to set up their own Ubuntu 16.04 VM or import the one given by me before the workshop.

In this workshop, we will teach students how to write smart contracts in the Solidity programming language. Solidity is easy to learn, but hard to get right.
The approach to training we’ll take in this session will be to provide a series of simple coding challenges, where participants are asked to write the code to implement a simple program, such as a coin toss, a transferable token (like a coin), or an auction. We’ll allow an appropriate amount of time for each step, and then provide a solution.
Then the fun part! We will walk the participants through the steps to break their contracts.
Classes of vulnerabilities we’ll explore include:

For this workshop, participants do not need to have prior knowledge about bitcoin. The workshop is divided in three strategic sections.
Section 1–Bitcoin fundamentals – 45 minutes
Hands-on exercise:
Participants will download the Electrum software wallet and I will transfer bitcoin to each of their generated addresses (small amounts, obviously). They will be able to track the transaction in the blockchain using blockchain.info.
Section 2 – Clustering, tagging and basic techniques to trace transactions – 1 hour
Hands-on exercise: Using a dozen of bitcoin addresses, participants will be tasked to trace transactions and conclude whether it is possible to know where the money was cashed out and what can be inferred from the money flow.
Section 3 – Advanced techniques behind tracing transactions using GraphSense API and Python open-source libraries – 1 hour
Hands-on exercise:
For this exercise, an environment will be provided to participants with the tools and the data installed. If needed, they can easily replicate the environment at home.
Participants will be tasked to extract information from a list of addresses using the GraphSense open source API. Then, they will graph the data based on the techniques presented above.

Security teams and app developers have thought a lot about online authentication, but we haven't applied the same rigor to designing systems for authenticating over the phone. At Twilio, product and engineering teams have spent the last year thinking about this problem and how to make the experience better for both the customer and the call center agent. In that time, I've called dozens of contact centers to learn about how everyone from startups to Fortune 50 companies attempt to identify and authenticate the end user. This talk will take a look at that research and outline best practices you can use in your own call centers. You'll leave the session understanding what information should be made available to the agent and what kind of product features you can build into your web or mobile application that can facilitate phone authentication.

The goal of the talk is to answer a few questions we often see or hear : “ATT&CK is nice and all, but how do I (we) get started?“, “How can I (we) detect those TTP?“, “Why use the ATT&CK Framework?“, etc. The ATT&CK Framework from Mitre is the new honest in the InfoSec world. There’s a lot of open source projects that use it, commercial products have started using it to show what TTP they cover, it even has it’s own conference : ATT&CKcon.
