  • In this episode of Security Headlines, we are joined by a great mind in the  

    memory security space. A spark was created when Theofilos peaked   

    into the realms of security. So he packed his bag and got to the next plane to the US in order to deep-dive more into the security field during  

    his studies. He became fascinated by the world of writing exploits  

    and "smashing the stack" as we say in the hacking field.  He is a   

    brilliant guy when it comes to memory attack and he has co-written a   

    solution that solves the stack canary problem.   

    We had the chance to sit down with Theofilos Petsios and    

    get to hear his view on security, development and a lot more.  

    That you can tune into right here:  

    Stack canaries is a security mitigation technique that has been widely  

    adopted and you will find it in most systems today. But does it really work?  

    Topics that we touch upon in this episode:    

    Stack canaries   

    Address layer space randomization   

    Blind Return Oriented Programming (BROP)   

    Return Oriented Programming    

    Static code analysis    

    Rest in peace Andrea Bittau    

    security mitigations   

    Write Xor Execute(W^X)   

    Dynaguard   

    Where stack canaries fail and the operating systems approach to it.  

    hardening systems  

    where the future of security is going  

    CVE's over time   

    Memory corruption bugs   

    builtin security in the compilers    

    Security vs Overhead   

    Using memory in the Thread-local storage

    adoption of security mitigations   

    stack clash   

    Pin, Intel's dynamic binary instrumentation framework     

    Defense Advanced Research Projects Agency   

    whitepapers and Proof of concepts    

    Fuzzing    

    building better security tools    

    Cost vs benefit in the security field     

    Switching from userspace to kernel space mitigations   

    linters    

    secure codebases    

    formal verifications   

    "Stack canaries is just one little stone, one a the beach that keeps getting hit by big waves"

  • In this episode of Security Headlines, we are joined by  

    the Hacker Johnny Xmas. Johnny is a very interesting character   

    with a lot of fun projects behind him.   

    Join us as we get to hear Johnny's stories as we deep dive 

    into this weeks episode of Security Headlines:

    ## Venmo

    After giving a talk about it and releasing software that made everyone  

    able to easily abuse this, Luckily venmo took action and limited the 

    amount of data avaliable. Johnny found a way to generate api keys with  

    just making a simple request to the 

    ## Bypassing Webb application firewalls   

    A lot of firewalls just focus on IP filtering which is a huge problem  

    when, in todays world it is really easy and cheap for a consumer   

    to aquire a large sets off ip addresses.  

    One provider of proxied ip addresses is Hola VPN that lets their free   

    users act as exit nodes that they sell using platforms such as luminate.

    Other people have adopted this approach but with mobile development toolkits.  

    ## Grimm    

    Johnny is currently working for the security engineering firm Grimm, a company known for its involvement in the ICS(Industrial control system) security work.  

    Currently working on developing 

    Grimm is currently hiring people, do you want to get paid to develop security training platforms ?

    then Grimm is the place for you!

  • In this podcast episode of Security Headlines: Carl Lerche, Rust developer and

    maintainer of the popular Rust programming library Tokio joins us.

    He walks us through what Rust and Tokio is, how companies are building their stacks with Rust.

    This and a lot more on this episode of Security Headlines!

    Carl heard about this new programming language called Rust and wanted to check it out.

    What started as a hobby project led Carl down the rust path and he now works for Amazon as a

    Rust developer! Helping Amazon build stable infrastructure.

    We get to hear the story of how Tokio got started and how the Rust programming language has changed

    over the years.

    Since a large chunk of Tokio code is focusing on making it easy for developers to write asynchronous functions.

    And be able to write fast code that does not get stuck and lets the data flow.

    But how does non-blocking code really work? What differs Rust from the programming language Golang is

    Golangs, adoption of green threads instead of using regular threads.

    Carl walks us through how this works and how Rust tackles this problem "the Rust way".   

    Do you want to build reliable network services with Rust?

    Then Tokio is something you should check out, try out the new 0.3 release here:

    https://github.com/tokio-rs/tokio/releases/tag/tokio-0.3.1       

    In this episode we also cover:   

    slowing down syscalls to protect against Spectre

    async syscalls with io-uring

    building high-performance systems with non-blocking sockets

    writing code without syscalls

    getting started with Tokio

    async operating system api's

  • HD is a very interesting character, founder of Metasploit, security researcher, phone phreak, ruby hacker

    and the founder of the company rumble!

    He joins us in this episode to tell us the story of Metasploit, making security research

    and internet scanning more accessible and normalized.

    HD picked up an interest in computers and the telephone system at an early age and

    spent his time reading ezines, 2600 and other magazines that talked about the force of technology and the

    creative exploring we know as hacking.

    The passion went from just making silly screen savers to starting to play with, the analog phone system.

    Phreaking away on the phone lines and using the knowledge to travel wherever he wanted, on the phone lines.

    In 2003, at the time where the internet still was young and the security research where kept in the dark.

    HD wanted to shine some light on this and instead of commercializing and building a proprietary product he

    created metasploit.  In order to make exploits easy to use and available for the business side and the hobbyist.  

    HD received a lot of push back for doing this. A lot of people did not want to make security tools and techniques  

    available for the wide majority to use.  They tried to get him fired, hares him and a lot more :/   

    This mob of angry people did not stop him from keep working at metasploit. Countless hours were spent porting   

    exploits to it. Making them easier to use and more accessible for everyone to use.    

    A couple of years later the metasploit project got bought up by the US-based company "rapid7"   

    which is home to several security related projects.   

    One of these interesting projects is Project Sonar. Project Sonar is continuously scanning and indexing   

    the entire internet.  Creating a huge map of every device on the internet that you can search on based on timestamps.   

    Like a modern-day time-machine for exploring devices on the internet.  This can be used for keeping track of   

    types of things, such as tracking Hillary Clinton's email server.     

    Exploring the internet on a larger scale like this of course does not come without finding a lot of interesting   

    things, HD tells us about the time he found a surgical robot that was being used for operating on people   

    with a publicly accessible web interface.   Luckily this was quickly reported and fixed!    

    Evolution is pushing innovation and scanning the entire internet, which was very hard to do a    

    while back is now not only cheap but can also be done in a couple of hours.    

    Today HD is the CEO of a company called Rumble, and has gone from exploring the public internet to   

    exploring the inner realms of intranets and internal networks.

  • In this episode, we talk with Maksymilian Arciemowicz, security research    

    that has found bugs in a large chunk of systems, active in the security field   

    since 2005. He is the founder and maintainer of cxsecurity which is a website   

    that index and host security vulnerabilities for everyone.   

    Cxsecurity is home to a lot of exploits and security research, in this episode   

    we get to hear the story of how it got created by its founder Maksymilian!   

    One of these types of communities is a mailing list called bugtraq.   

    Maksymilian learned how to find security bugs thanks to that mailing list and  

    soon after finding his first couple of bugs he teamed up with a friend to start a    

    website called *securityreason.com*. SecurityReason took the security research from the mailing list   

    and displayed it in a nice web interface.   

    The two founders wanted to go different ways, Maksymilian wanted the research to stay open and not    

    commercialize on it.   

    The website got shutdown and Maksymilian forked it into a new better version called cxsecurity.com!

    In nature, the power lays in the entity with the most muscles but on    

    the internet, the power is in the person with the most knowledge, the power comes  

    from the intellect. Whoever comes up with new ideas and is able to prove it wins    

    the intellectual battle, Maksymilian explains.   

    Since 2005 Maksymilian has been able to find security holes in:  

    * IPFilter in openbsd, which was used before they switched to   

    * Freebsd      

    * Magento   

    * Mac osx    

    * phpmyadmin    

    * PHP       

    * NetBSD        

    * Vsftpd       

    * apache      

    * Solaris        

    * Thunderbird       

    * Opera         

    * libc         

    and a lot more!

    We are super happy to have a true hacker spirit with us in this episode     

    on Security Headlines!

    In this episode, we cover topics such as:    

    How the security landscape has changed since 2005 and how easy it was    

    to hack back then.    

    Using regular expressions to make security research better and faster!    

    How to submit security exploits to software vendors.    

    CVE, lack of description       

    Stories from the heart of the security scene       

    Suricata and Artificial Intelligence      

    How to protect your systems.      

    Development and a lot more!      

    static code analyzer, he has written his own static code analyzer for PHP.   

    We of course sidetrack a bit into OpenBSD and when a person such as Maksymilian says:    

    *OpenBSD is the most secure operating system in the world*   

    We can just smile :)

  • Summary:    

    In this podcast episode of Security Headlines our host talks with Kristaps Dzonsons, a long time

    OpenBSD user, writer of beautiful software and deep water diver.

    We cover a lot of software development, security, the BSD space and of course diving.    

    Security is something that is very hard, we are all human and mistakes happen.

    In 2014 at a EuroBSD conference, Kristaps

    gave a great talk about what we should think about when we want to

    produce safe code.    

    One of the things he highlights is that ideally, we should:    

    Write defensive code, use a team of code auditors, QA

    Use up-to-date, audited libraries with a history of attention to security

    use a language with formal underpinnings and proof of correctness

    run on systems supporting your defensive strategy

    And while we're at it, we might as well ride our unicorns to work.

    Unfortunately this workflow is not yet adopted.  But since the tools are getting

    smarter and smarter, more and more people are adopting fuzzing and the ecosystem is evolving.

    There is a lot of reasons to be optimistic about the future!     

    One thing we can do to make our programs a bit safer is to look at each

    part of the program and ask ourselves, does this part really need

    privileges to do these things?   Luckily a great new innovation from OpenBSD comes riding

    in like a knight in shine armor, like a hero in a medieval movie.

    And its name is Pledge, pledge allows your program to easily predefined the access rights it

    needs and if it breaks the promise, the process dies.

    It's an easy to use way to approach the entire Mandatory Access Control swamp...      

    Pledge

    Originally implemented as Tame in OpenBSD, but rebranded as Pledge in OpenBSD's 5.9 release.

    Pledge makes security a lot easier for the developer!  If you want a function you have to

    only have the privileges of being able to open files or something similar. Pledge makes it super-easy for

    you as a developer to in 3 lines of code, in order to only allow a function to do what its suppose to do and

    nothing more, so when attackers come and manipulate your function to do other things, Pledge comes riding in

    and kills the process, no questions asked!

    Kristaps has implemented both Tame and Pledge into production and we get to hear his advice

    on how to do it.

    Pledge adoption is growing and growing, and you can use it with a large number of programming

    languages.  Just search for pledge and the programming language of your choice and someone has

    most likely made a library for it.

  • Summary:   

    In this podcast episode, we interview Mischa Peters which is a long time   

    BSD user with a background in the world of data centers and ISP's.     

    One of his latest projects is OpenBSD Amsterdam which is a pure-hearted   

    OpenBSD virtual machine hosting provider.  That is running 100% OpenBSD,   

    it's even using OpenBSD's own hypervisor.  We deep dive into   

    OpenBSD Amsterdam, scripting with ssh, awk, and the basic tools, BSD, Hack-tic and    

    a lot more!    

    OpenBSD Amsterdam is one of the many interesting projects in the BSD space.   

    Being a pure hearted OpenBSD virtual machine provider.  The project launched as a hobby project by   

    Mischa Peters in 2018 and the first month already 40 people where interested in spinning up a virtual machine   

    with OpenBSD Amsterdam.   

    What makes it special is that it runs OpenBSD own Hypervisor, unlike the majority of hosting platforms that  

    run qemu/kvm or Xen.     

    So what you get is an OpenBSD virtual machine running on OpenBSD host. So it's OpenBSD all the way.    

    Mischa started playing around with this new hypervisor project for fun and wanted to do something   

    bigger with it, Having a background running servers in datacenters as well as running his on internet service  

    provider(High5) which he started in 1999.

    In this episode, we also get to know how it was to work for Xs4all in the 1990'ies. Xs4all is a Dutch internet  

    service provider that came out of the *Hack-tic* scene.   

    Which was a Dutch hacking community and magazine that where active between 1989 and 1994.    

    This scene has been very active, creating conferences, being a voice     

    for internet activism, suing the Church of Scientology and much more.     

    Mischa, like many others, got introduced to SunOS Unix systems in school and went deeper and deeper into the   

    Unix based rabbit hole. He ended up running Redhat and then found the wonderful world of BSD and   

    was liberated from Linux through the adoption of FreeBSD.     

    Mischa is the kind of person that handles the juggle between multiple projects demanding projects, a   

    day job, a family with kids, a much more.    

    We also talk about performing automated package management   

    on OpenBSD, doing kernel upgrades, and automating things with simple command-line scripting.   

    Sometimes Ansible is just a mess and the same thing can be done simpler with just a for loop   

    some ssh and some basic command line hacking.   

    Thanks to the OpenBSD Amsterdam project, a large chunk of cash has been donated to the OpenBSD   

    foundation which helps the development of OpenBSD moving further.     

    But most important: It's helping the adoption of OpenBSD!  

    Do you want to learn BSD?  Host your own email?  Setup Wireguard?   

    Then OpenBSD Amsterdam is a good start for you.

  • In this episode of Security Headlines, we jump into curl with   

    its founder and maintainer Daniel Stenberg.   

    We talk security, CI systems, creation of curl, Fuzzing, IRC bots and a lot more!  

    Few software developers never even get near to having one   

    of their projects being picked up by a larger community.   

    A project that started as a currency plugin to an IRC bot.  

    Spun off and ended up becoming bigger and bigger resulting in being 

    adopted by over 10 billion devices.  Well, this project is called   

    curl!  Curl is known to be the stable swizz army knife that can  

    be used for making various types of transfer requests.  

    Need to download a file? Curl is here for you        

    Need to test a socks5 proxy? Curl is here for you  

    Need to download an ezine over Gopher? Curl is here for you     

    Need to test a unix socket? Curl is here for you     

    In this episode of Security Headlines, we are joined by Daniel   

    Stenberg who is the founder and maintainer of Curl.   

    He has even been awarded a gold medal by the Swedish king for   

    his work with Curl.

  • In this episode, we are all about FreeNas, the world's largest NAS system, running FreeBSD as its base.  

    The founder of FreeNas Olivier joins us, walking us throw how FreeNas started and how the system   

    has grown since its start in 2005. The conversation takes us through the jungle of FreeNas and we end up

    landing in Netflix's land of FreeBSD adoption and Olivier's latest project the BSD router project.    

    Sit back, relax, and enjoy this episode of Security Headlines.  

    We are back with another episode in the BSD theme episode!   

    In this podcast episode, we are talking about FreeNAS, the worlds biggest Network-attached storage(NAS)    

    operating system.   

    And we of course have the founder of FreeNAS with us, Olivier Cochard-Labbé!    

    Olivier started FreeNAS in 2005, with not a lot of knowledge on how to do it but with a determintation   

    of creating a multimedia system that he could use.    

    He wanted something small so he tried to compile   

    [busybox](https://en.wikipedia.org/wiki/BusyBox) but failed, he kept on trying and ran into FreeBSD!   

    He named the system FreeNAS and the first month he was able to get a bit over a thousand downloads, which 

    is very impressive for a new project.    

    The project grow and grow and it attracted a big community taking up to much of Olivier's time.   

    This became harder and harder, Especially when you have a family and a full-time   

    job and other hobbies to attend.   

    Olivier was getting more and more to do as the project became bigger.  One particular example of this   

    that he brings up is a security bug that was very severe and of course filed on a Friday. 

    The security hole was a critical one, FreeNAS allowed root console access from the web interface   

    without requiring authentication.      

    The company *iXsystems* offered to allocate some developers to work on FreeNAS and Olivier   

    handed over the FreeNAS project to them with the requirement that it shall remain free and opensource!      

    Olivier is currently working for Netflix, helping them stream movies to the world using    

    the raw power from the FreeBSD operating system that runs Netflix's Content Delivery Network.   

    Join us as we jump into the wonders of FreeNAS, the BSD router project, and a lot more!

  • In modern stacks, a large chunk of applications run in container environments   

    such as docker and systemd-nspawn.  However, these applications are not built for security.   

    The security community has proven it again and again that privilege escalation attacks   

    are very serious with attacks such as Dirty Cow and CVE-2016-3135.   

    A way to tackle the problems of running applications with a low privilege user without   

    that application being able to interact with other running applications is to use *user namespaces*.      

    Using user namespaces you can hide process id's to the applications and provide a more sandboxed environment.   

      

    Alex wanted to the distribution of multiplatform applications easy 

    which led him to sandboxing and namespaces, today he   

    maintains the "chroot on steroids" project *bubblewrap* which is a sandbox platform for running    

    sandboxed applications in different namespaces.    

    Alex is also a long time user of Linux, with 20 years working for Redhat.   

    He started to code on the commodore 64 and has been a developer ever since. In school he  

    got introduced to Solaris and jumped deeper and deeper into Linux rabbit hole.   

    Working on Linux allows Alex to work from home in the suburbs of Stockholm  

    and work on programs that get used by a global user base.

    In this episode, we talk about how it has been to work on sandboxed   

    desktop applications and how flatpak has grown.    

    So far there a has been a handful of different CVE's for bubblewrap 

    that we talk about.

    Flatpak has gotten bigger and bigger and "flathub" has come to see the light

    , flathub is a place where all Linux users can get sandboxed desktop

    applications.

    Flathub is running on a stable Rust backend, Alex picked Rust to be the backend as one of his first larger Rust projects.  

    We of course talk about how Rust is becoming more part of our daily lives  

    as more and more applications are being ported to it, like librsvg journey from being written in C to now being a rust code base, as well as libraries  

    being written in Rust.  

    If you are maintaining an application with a graphical user interface and you target 

    an audience that is running Linux on the desktop, we recommend   

    that you get your application on flathub.   

    Here is a guide on how you can do that:   

    https://github.com/flathub/flathub/wiki/App-Submission

    This podcast was made possible with running zoom with flatpak:   

    $ flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo   

    $ flatpak install flathub us.zoom.Zoom 

    $ flatpak run us.zoom.Zoom

  • Tarsnap is a backup service running with the slogan "Online backups for the truly paranoid".   

    The service has well earned its slogan as a secure backup option.   

    Created in 2006 by at the time FreeBSD's security officer Dr. Colin Percival, who was responsible for FreeBSD's security advisory.   

    Colin is not only a successful entrepreneur but also a dedicated FreeBSD user.   

    Colin has been getting his hands dirty with FreeBSD in the late 1990'ies when the firewall in his family house   

    running openbsd crashed due to disk failure. After changing the disk he did not manage to   

    figure out how to install OpenBSD so he went with FreeBSD.   While studying for his doctrine, he got concern   

    about security, that led him to use freebsd where he later jumped on as FreeBSD security officer.   

    Being the FreeBSD's security officer gave him knowledge of security holes before anyone else did and   

    he needed a secure backup solution for storing his files.   After some head scratching, he decided to   

    go the startup route and create his own backup solution. After getting several user requests about having  

    password-protected key storage, Collin created Tarsnap's secure cryptographical solution for 

    protecting keys called "Scrypt", which later got picked up by several opensource 

    projects such as the cryptocurrency project Litecoin.    

    Colin is a very intelligent and trustworthy person, to improve security when connecting   

    and staying connected between machines he creates spiped. Adding a layer of safety on top of just using regular   

    ssh, to mitigate attacks and weaknesses caused by OpenSSL.   

    Because scrypt has a heavy resource need, making it hard for attackers to crack, it became a more secure alternative then the standard hash functions we use in modern systems such as sha1 and md5.   

    The project started to growth and it was soon adopted by various larger companies   

    such as stripe.  

    If you are interested in finding and submitting bugs in Tarsnaps own code base, Colin has put up a Bug bounty

    rewarding the people that find all kinds of bugs in the code base, a fun fact is that a majority of the security bugs   

    that gets submitted is not found by security researchers looking for holes but by average developers looking at   

    the functions in the code.  

    Today Tarsnap runs on a large set of different systems by a diverse crowd, providing secure storage of   

    data thanks to its stable code base and amazon s3.  

    Colin also donates Tarsnap's December profit to the opensource community sponsoring the FreeBSD foundation, the EuroBSD  

    conference, the bsdcan conference, bsdnow podcast and several other projects.   

    We are super happy to have Colin as a guest on Security Headlines!
