Hi! My name is Cariad Keigher (keyr-ree-ad kee-yer) and I am a Senior Analyst for a Security Operations team at one of Canada’s largest natural resource companies. I’ve been working in the information security space for the past decade and believe that community via information sharing is the best approach in working against current problems facing cyber security. This can be achieved either through information sharing and analysis centres, online communities, and even to a certain extent conferences.

Previously, I’ve been a consultant for a small boutique cyber security firm, a support engineer at an anti-virus company, and a systems administrator at a local managed service provider. I’ve also ran a service that parsed and stored leaked data from system breaches released to the Internet.

Outside of my day-to-day job, I have an interest in roller skating, vegan cooking, video games, queer issues, and intersectional feminism. I use “she” and “her” pronouns and I like to write code using Python and work on old computers–I have a long-standing project to modernise a Macintosh Quadra 800.

My primary language is English. I hold citizenship in both Canada and Ireland. The content expressed on this website is representative of my own opinion unless specified otherwise and not of my employer or any organization I associate with.

Outreach and publicity

Working in cyber security can sometimes get you a lot more attention than you desire. I’ve appeared in a few publications and have spoken at a few conferences and companies.

Here is a sampling of times where I appeared in the media:

  • I was interviewed by Forbes in 2013 after having spoken at BSides Vancouver on extracting personal details such as phone numbers and BlackBerry PINs via Twitter. I very much have an interest in privacy in addition to security and wanted to point out the problem with public social media services.
  • CSO Online took something I posted on my old Twitter account about malware and the Sony breach from 2014 and wrote a story about it. The gist of it is that a friend of mine had signed the malware that attacked Sony using a certificate that was leaked and it lead to a major AV vendor to erroneously claim that signed malware was used in the attack.
  • Kotaku Australia picked up on an old blog entry where I demonstrated that a breach affecting the PlayStation Network (PSN) was false.

I have some of my conference talks listed here:

  • BSides Vancouver 2018 (March 2018) - Performing Your Own Dentistry - Challenges, Unknowns, and What is Overlooked in Security Log Collection - I gave a presentation on how it is to collect security log data within my company. (Slides, Video, Blog)
  • Facebook (March 2016) - I was invited to Facebook’s offices in Menlo Park to give a presentation on Canario. I am unable to make the slides available but I went over the challenges I faced in collecting mostly-unstructured data from system breaches and turning them into something machine-searchable.
  • OWASP Vancouver (November 2015) - Effective Password Hashing - This was the first time I gave a formal presentation on password hashing, having taken lessons learnt from breaches that I had done research on. (Slides)
  • BSides Vancouver 2014 (March 2014) - Talk title is long-forgotten and the slides were done in an experimental HTML5 format, but I gave a presentation on Canario which was then named CanaryPW.
  • BSides Vancouver 2013 (March 2013) - Being an Avivore - Searching Twitter for Data computers–this was the aforementioned talk that lead to an interview by Forbes. I did release code for it but the slides are long gone and I’ve since yanked the repository.
  • Hackers on Planet Earth (July 2010) - “Brilliants Exploits” – A Look at the Vancouver 2010 Olympics - This was my first-ever conference talk and was early on in my information security career. It was more of an adventure talk on how we tried to see how the physical security aparatus was developed and all of the problems we faced trying to find out whatever details we could.

I should note that my former legal name and previously assigned pronouns are mentioned in much of what it is linked here. I ask that you do not use this name when referring to me as that is no longer valid and to also stick with the aforementioned “she” and “her”.

It’s very rare for me to speak to the media even considering the above. The Forbes article was the last time I bothered to give an interview to a journalist.

Contacting me

My primary means with interacting with the Internet is via my Twitter account. It isn’t meant for professional purposes but from time to time I will talk about information security or share something other than queer issues, weird video game stuff, or photos.

If Twitter isn’t your forté, I am available via e-mail but please be aware of the following:

  • Don’t e-mail me about stuff I’ve tweeted. You can reply from your own Twitter account if you have questions or comments.
  • E-mails sent to me are not private and shouldn’t be treated as such. There is no security during the message transport and additionally there is no contract between us.
  • I am available for consulting work but I only take them on a case-by-case basis and I will not work during standard business hours. As well, I have priorities outside of my dayjob that I need to tend to first and foremost.
  • It’s okay to contact me regarding queer issues, but please bear in mind that I will enforce my boundaries and will let you know if you cross them. I take these matters quite seriously and will respect your privacy.
  • Do not address me by any name other than what I have specified on this page.
  • If we share last names, I am unable to provide you with a vanity e-mail address.
  • I do go by “Cari” with those I am friendly with, but I ask that you don’t address me as that unless I make it clear that it is okay.
  • I will reply to your e-mail eventually. It’s a personal address and I do know when I get new e-mails in my inbox.

If you’re okay with the above, feel free to e-mail me: cariad@keigher.ca

You can also reach out to me via Google Hangouts, Signal, Telegram, Discord, and IRC. I give these details out quite sparingly although I use “katelibc” on most IRC networks including Freenode.

I’m periodically at conferences and meetups, and am happy to meet with people but please understand that I am usually pretty busy at these events and will only be able to make time for you if I can.

Lastly

Should I ever run into a situation where I lose control over a service such as Twitter, I have a SHA256 hash below that I’ll reveal:

Proof of its existence elsewhere can be found in this tweet from May 2018.
