Automotive security is now part of public dialog, with researchers continuing to investigate, media outlets reporting, and dogecoin ascii art catcher United States Senators voicing concern over vehicle security.

The last portion of talk dogecoin ascii art catcher attempt to convince more researchers to enter the automotive security arena by showing how to get started tools and techniques while fielding questions from the audience. As always, make sure to stay until the end for a special bit of information. He is also heavily involved in bleeding-edge automotive security research. Valasek specializes in offensive research methodologies with a focus on reverse engineering and exploitation.

Known for his extensive automotive field research, Valasek was one of the first researchers to discuss automotive security issues in detail. His release of a library to physically control vehicles through the CAN bus garnered worldwide media attention. As a Windows security dogecoin ascii art catcher matter expert, he is quoted in several technology publications and has given presentations on the subject at a number of conferences.

Does an active cyberwar inform and influence how network defenses are designed and implemented? How is the art of penetration testing advancing the state of wartime preparedness? How do we get a globally shared Internet on a war footing, or is it already? How do the criminal justice systems align with the need for cultivating offensive and defensive expertise?

How does anyone "win" a cyberwar? Tod Beardsley is the Engineering Manager for the Metasploit Project, the world-renowned open source penetration testing platform. He has over twenty dogecoin ascii art catcher of hands-on security knowledge, reaching back to the dogecoin ascii art catcher days of baud textfile BBSes and in-band telephony switching. Today, he is passionate some might say militant about open source software development, open source security research, and data liberation.

Jack Daniel - "InfoSec: What we know, and what we need to know. Although a new and continually evolving field, dogecoin ascii art catcher have learned a lot about securing systems, and we've defined many of the remaining challenges. Unfortunately, we often find ourselves re-learning the same lessons over and over.

In this presentation a number of studies and reports from the past 50 years of infosec will be reviewed and the results examined for the things they show us- both the known and unknown. With the goal of growing infosec beyond our seeming eternal state of infancy, this discussions will embrace some common beliefs and eviscerate others. This talk is intended to spur conversations, reflection, and heavy drinking.

A technology community activist, he supports several information security and technology organizations. We all know that crypto is hard.

But thinking about crypto effectively is not hard. Did you pass notes with your friends in elementary school? Keep a secret notebook? Then you have a background appropriate to the task. In this roller coaster of a talk, I'll cover what crypto works, what doesn't work, the basic components and how they're put together.

I can't tell you how to build a cryptosystem in fifty minutes, but can give you the basics of how it all works. Think of this as a workshop in high-performance driving, as opposed to mechanical engineering. Jon Callas is a cryptographer, software engineer, and entrepreneur. He is fond of Leica cameras, Morgan sports cars, and Birman cats. Kevin is a Manager at Labs focusing on information security and compliance issues faced by financial institutions.

Kevin is the creator of the MiniPwner, a pocket-size penetration testing device used to get remote access to dogecoin ascii art catcher network. As we dogecoin ascii art catcher on reading on the news, Social Engineering remains one of the most important threats for information security.

We can build secure systems, keep environments patched and still bypass them by means dogecoin ascii art catcher tricking people into performing tasks or even bypassing security features for us.

Because of this, I still perform research into new attack vector and way to compromise people by means of social engineering and social networks. In this presentation we will discuss a new tool called Cartero. Cartero is a modular Social Engineering Framework divided into simple to use CLI commands that perform independent tasks. During the talk we would introduce the tool, talk about a few commands and how it integrates to other tools.

Matias performs penetration testing, code reviews, social engineering, web applications testing, identifies system vulnerabilities, and designs custom security solutions for clients in cloud, software development, telecommunications, and financial services.

Nick Espinoza - "Week to Weak: Weaponization of Vulnerabilities" Abstract: We conducted research into how quickly vulnerabilities are dogecoin ascii art catcher into detected exploits and and categorized the results by products and technologies. Nicholas Espinoza is an engineer who works in the defense and information security space. As the meaty corporate network dissipates into the free range organic vegan cloud based tofu that is most silicon valley startups, Red Teaming engagements rely more on attacks that target users in a personal way.

In this talk I'll share some tips, tricks, and tales of how high interaction with select users becomes the best way to bypass modern security controls. FuzzyNop is a computer who knows how to computer.

This two part presentation provides a detailed overview many of the issues surrounding Point of Sale system security. The first part of this presentation hi-lights those implementation problems that make point of sale systems so very easy to compromise in the first place.

This will be done using multiple real world examples and scenarios involving even supposedly "secure" point of sale and cashless payment systems at large restaurant chains, retail environments, grocery chains, and other environments.

Once we have established the ease of compromising these systems, and how these implementation dogecoin ascii art catcher can subvert even the best security controls on the PoS systems themselves, the focus will shift to malware commonly used in PoS compromises. Using examples found in the wild, the talk will demo certain malware, and discuss analysis of the same.

Ryan Linn - "Vomiting Shells: Tracking the Splatter Patterns" Abstract: Penetration testers and attackers dogecoin ascii art catcher use tools without understanding the impact or what is left behind.

This presentation will look at a variety of different methodologies for delivering shells and then track the artifacts that are left behind. For attackers, we will be discussing some additional ways to limit your footprint. For defenders, we will highlight dogecoin ascii art catcher areas for review and show patterns for a number of the most common ways of achieving shells. Along the way we will highlight the IOCs that will help defenders more easily identify the tools and methodologies used for attacks, as well as ways to limit their impact.

Ryan has more than 15 dogecoin ascii art catcher of experience in Information Security. Dependence on software libraries and frameworks continue to grow in popularity. More scrutiny is being placed on reviewing the source code of these dependencies for security vulnerabilities, but little attention is being placed on software dependencies while in transit.

We will also demonstrate the impact of these weaknesses using a newly developed tool and provide advice and guidance on defending against these attacks.

There are people that watch trains for a hobby, yet we still struggle to track what our own boxes are doing. Don't get me wrong, there's a bunch of great stuff out there to draw pretty pictures of cyberthingies, however most of it is boss entertainment dogecoin ascii art catcher not suitable for adults and today's happenin' youth.

Is it possible to "watch" our networks in some meaningful way, without getting overwhelmed? If you've used ssh-keygen, think of it as a randomart version of internet traffic. Or, if you've ever defragmented a hard drive, think of it as a cylinder map of internet networks.

The synspot tool will be released and demoed, its goal to allow users to visualize what ""normal"" is, so that we can detect and research dogecoin ascii art catcher stuff that seems bananas. Also by comparing synspots, dogecoin ascii art catcher can see what users have in common and how they differ. It's Not Just You" have been downloaded and indexed many times by automated bots.

These days he spends dogecoin ascii art catcher time writing remote unauthenticated vulnerability checks by reverse engineering changes introduced by security patches and identifying the root cause. Jeremy has recently started developing a framework to extract data from firmware images and perform automated analysis.

His research in this area has uncovered a compelling number of undocumented risks that impact a large number of devices and user environments. I also seem to have three main roles I play all adorably to try to get into my target.

I thought it would be cool to share at least a story from each one of these roles. Some have pictures, some with just witty comments. Though all three will come more importantly with ways that would have stopped me from being successful. Far from it this talk is to show how EASY these attacks were done and how every single attack has one common thread connecting all of them! Also creator of http: Considering voter apathy and the sheer amount of noise from political ads during an election year, does a difference in election spending or donations received really matter all that much in polls between candidates?

But other then massive donations, are there any other means to sway voters, and on a budget with better ROI than Citizens United? What if news of this type of attack entered mainstream news, how would the polls and candidates react?

Facebook incites violence by allowing false-rumors to circulate. Twitter only recently banned large communities of neo-nazis and white supremacists organizing on the site. Discord continues to be an organizational hub for Nazis and the Alt-Right.

Why should a private company have the role of a cultural censor, and how can we redesign our social media to democratize censorship?

To be absolutely clear, censorship serves an important role in social media in stopping verbal and emotional abuse, stalking, toxic content, and hate speech.

It can also harm at-risk communities when applied too broadly, as seen in recent well-intentioned U. Censorship within the context of social media is not incompatible with free-speech. First, Freedom of Speech in the United States is largely regarded to apply to government criticism, political speech, and advocacy of unpopular ideas.

These do not traditionally include speech inciting immediate violence, obscenity, or inherently illegal content like child pornography.

Being banned from a platform is more akin to exile than to arrest, and leaves the opportunity to form a new community accepting of whatever content was banned. I think had the U. Bill of Rights been written after the genesis of the Internet this would be a non-issue, and we would have a definition for a public commons online.

Regardless, I want to talk about what should be , rather than what is legally excusable. Corporations have public perceptions which effect their valuations. A private corporation, once they have sold me a phone, should not have say over what I can and cannot use that phone to do.

The same argument applies to social media. Facebook and Twitter have a vested interest in limiting conversations that reflect poorly on them, but do not otherwise need to engender a healthy community dynamic. Sites like Reddit that are community-moderated have an advantage here: Their communities are self-policing, both via the main userbase downvoting inappropriate messages until they are hidden, and via appointed moderators directly removing unacceptable posts.

This works well in large subreddits, but since moderators have authority only within their own sub-communities there are still entire subreddits accepting of or dedicated to unacceptable content, and there are no moderators to review private messages or ban users site wide. A scalable solution will require stronger public powers. The premise is simple: Anyone can run their own miniature social network, and the networks can be linked at will to create a larger community.

Perhaps an improvement, but not a great one. While in theory users could react to censorship by creating a new Mastadon instance and flocking to it, in reality users are concentrated around a handful of large servers where the community is most vibrant.

A truly self-regulatory social community should place control over censorship of content in the hands of the public, exclusively. When this leads to a Tyranny of the Majority as I have no doubt it would , then the effected minorities have an incentive to build a new instance of the social network where they can speak openly. This is not an ideal solution, but is at least a significant improvement over current power dynamics.

It may involve a majority-consensus to expel a user from the community. The key is to involve the participants of the community in every stage of decision making, so that they shape their own community standards instead of having them delivered by a corporate benefactor. Care needs to be taken to prevent bots from distorting these systems of governance, and giving a handful of users de-facto censorship authority.

This should be not only compatible, but desirable, for social media companies. Allowing the community to self-rule shifts the responsibility for content control away from the platform provider, and means they no longer need to hire enormous translator and moderator teams to maintain community standards.

This is a story of when the Dutch secret service knocked on my door just after OHM, what some of the events that lead up to this, our guesses on why they did this and how to create an environment where we can talk about these things instead of keeping silent. Since the talk was not recorded, the following is my synopsis and thoughts. This post was written about a week after the talk, so some facts may be distorted by poor memory recall.

They initially identified themselves as members of the department of the interior, but when asked whether they were part of the secret service, they capitulated.

The agents began by offering all-expenses-paid travel to any hackathon or hackerspace. All the speaker needed to do was write a report about their experience and send it back. A relatively harmless act, but it means they would be an unannounced informant in hacker communities. When the author refused, the agents switched to harder recruitment techniques. They pursued the author at the gym, sat nearby in cafes when the author held meetings for nonprofits, and likely deployed an IMSI catcher to track them at a conference.

Eventually, the author got in contact with other members of the hacker community that had also been approached. Some of them went further through the recruitment process. I have two chief concerns about this. Therefore, there are likely many informants working for the secret service already. Second, this talk was about the Netherlands - a relatively small country not known for their excessive surveillance regimes like the Five Eyes. If the Netherlands has a large group of informants spying on hackerspaces and conferences around the globe, then many other countries will as well, not to mention more extreme measures likely taken by countries with more resources.

From this, we can conclude there are likely informants in every talk at significant conferences. Every hackerspace with more than token attendance is monitored. Most examples of decentralized organization are contemporary: Older examples of social decentralization tend to be failures: But not all leaderless movements are short-lived failures. One excellent example is Alcoholics Anonymous: An year-old mutual aid institution dedicated to helping alcoholics stay sober.

The twelve traditions are reproduced below:. For our group purpose there is but one ultimate authority - a loving God as He may express Himself in our group conscience. Each group has but one primary purpose - to carry its message to the alcoholic who still suffers. An AA group ought never endorse, finance or lend the AA name to any related facility or outside enterprise, lest problems of money, property and prestige divert us from our primary purpose.

Alcoholics Anonymous should remain forever nonprofessional, but our service centers may employ special workers. AA, as such, ought never be organized; but we may create service boards or committees directly responsible to those they serve. Alcoholics Anonymous has no opinion on outside issues; hence the AA name ought never be drawn into public controversy. Our public relations policy is based on attraction rather than promotion; we need always maintain personal anonymity at the level of press, radio and films.

Anonymity is the spritual foundation of all our traditions, ever reminding us to place principles before personalitites. The first theme stresses anonymity in an interesting way: Personal power is prone to abuse, both at an inter-personal level see the plethora of sexual abuse cases in the news right now , and at a structural level, where the organization becomes dependent on this single individual, and is drawn in to any conflict surrounding the celebrity.

The solution to a rock-star is to kick them out of the organization, and maintain a healthier community without them. AA has gone a step further however, and outlines how to prevent the rise of a rock-star by preventing any personal identification when communicating to the outside world.

When you are speaking to the press you are Alcoholics Anonymous, and may not use your name. For further discussion on rock-stars in tech communities, see this article.

The single-issue design is an unusual choice. Many social movements like the Black Panthers stress solidarity , the idea that we should unite many movements to increase participants and pool resources.

This is the same principle behind a general strike , and broad, cross-issue activist networks like the Indivisible movement. However, focusing on a single issue continues the trend of resisting corruption and abuse of power. AA keeps a very strict, simple mission, with no deviations.

The last theme, total organizational independence, is also unusual. Organizations that fear external attack, like terrorist cells, may operate in isolation from other cells with little to no higher-level coordination.

Avoiding both internal and external hierarchy, however, sacrifices both large-scale coordination and quick decision making. It is also used by Antifa, where local groups have no contact with one another and rely on collective sentiment to decide on actions. Overall, AA is an interesting introduction to decentralized organizations. I will revisit these ideas as I learn more. I recently encountered a very neat encoding technique for embedding images into Quick Response Codes , like so:.

A full research paper on the topic can be found here , but the core of the algorithm is actually very simple:. Dither the image you want to embed, creating a black and white approximation at the appropriate size. Redraw the required control blocks on top in full detail, to make sure scanners identify the presence of the code.

Setting the middle pixel of each cluster of 9 generally lets QR readers get the correct value for the block, and gives you 8 pixels to represent an image with. Occasionally a block will be misread, but the QR standard includes lots of redundant checksumming blocks to repair damage automatically, so the correct data will almost always be recoverable. I have extended that code so that when a pixel on the original image is transparent the corresponding pixel of the final image is filled in with QR block data instead of dither data.

This both makes the code scan more reliably and makes it more visually apparent to a casual observer that they are looking at a QR code. The original researchers take this approach several steps further, and repeatedly perturb the dithered image to get a result that both looks better and scans more reliably.

While their enhancements yield a marked improvement in image quality, I wish to forgo the tremendous complexity increase necessarily to implement them. I have long been an opponent of censorship by any authority. Suppression of ideas stifles discussion, and supports corruption, authoritarianism, and antiquated, bigoted ideas. I have put a lot of thought in to distributed systems, like Tor or FreeNet, that circumvent censorship, or make it possible to host content that cannot be censored.

However, the recent Charlottesville protests show another side of the issue. Giving the alt-right a prolific voice online and in our media has allowed the Nazi ideology to flourish. The progress of different hosting providers shutting down the Daily Stormer neo-Nazi community site shows how hesitant Corporate America is to censor - whether out of concern for bad PR, loss of revenue, perception of being responsible for the content they facilitate distribution of, or less likely an ideological opposition to censorship.

Ultimately, I still belief in the superiority of decentralized systems. Money-driven corporations like GoDaddy and Cloudflare should not be in the position where they are cultural gatekeepers that decide what content is acceptable and what is not.
