Excellent thread from on what it’s really like to work in tech. We’re very lucky to have her on the team, and everyone is lucky to have her working to keep people safe and tackle these hard problems!

One year ago, I made the jump from academia to tech. It’s been a wild ride so far, so I wanted to share a few reflections on the transition for others that might be considering tech roles. 1/many

Well this looks amazing. How exactly does one buy this? :) :)

A couple years ago, I was challenged to make a baby shower themed #wargame. Now I’ve moved the #game off Zoom and onto the #tabletop. It has a combat results table with the option to poop on new parents. So that’s a thing.

V proud of the team’s impact w/this report: “The Pentagon has ordered a sweeping audit of how it conducts clandestine information warfare after major social media companies identified & took offline fake accounts suspected of being run by the US military” washingtonpost.com/national-secur

📢1/ Today Stanford Internet Observatory & @Graphika_NYC are releasing a report analyzing what we believe is the first major covert pro-US/Western influence operation suspended by Twitter and Meta. Each has just released a data set of accounts involved. cyber.fsi.stanford.edu/io/news/sio-au

NEW: Pentagon opens sweeping review of clandestine psychological operations. A top Pentagon official directed military commands to account within 30 days for their psyops following complaints by Facebook/Twitter that the fake personas violated user rules.

The surest way to conclude that a moment is unprecedented is to fail to put it in context of the moments that have gone before.
Quote Tweet
This seems profound until you think about it for 5 minutes and realize that in previous eras there were literally single sources of information driving how people thought; the church, local newspapers, TV/radio, etc. The real change is that now anyone can spread a message. twitter.com/DavidVorick/st…

This is a great corollary to this parallel discussion from . It doesn’t change the fact that people should learn the risks of the diving catch, but if someone saves your butt w/one, tell their manager — don’t assume they know! twitter.com/ngleicher/stat
Quote Tweet
If someone does right by you, tell their boss and their boss' boss. Don't be shy. People often work miracles behind the scenes, and hope their leaders see it, but having been on both sides of that equation, visibility into the great work that happens cross organization is hard.

Hi, friendly manager here. Please let things fail. I can’t make systemic changes if you keep fixing issues and everything appears fine.

This tweet is for a specific type of person - especially young and hungry ones. I’m talking to the ones who jump in and quietly save things whenever their teammates and seniors drop the ball. Sometimes when not too much is on the line, you have to just let them fail.

At both the personal & institutional level, sometimes it’s important to let the process work itself out, even if it’s long and painful and you’re sure you could solve it way faster if you just jumped in yourself.

This is important advice, and it applies at an institutional level too. If your team isn’t funded for an initiative, and the team that is funded is ignoring it, stretching your capacity & jumping in can be worth it, but over time it distorts institutional priorities.

All in all, it’s a reminder that bad actors will exploit (likely already have) every messaging platform — analog, digital, private or public. If you’re designing or regulating messaging systems and you aren’t operating w/adversaries in mind, you’re probably enabling them.

As notes, recent spikes in FTC reporting indicate the broader trend is expanding. Bad actors learn from each other, — we should be careful not silo threat response. Tactics used for election disinfo often come from those used for financially-motivated harms.

Good piece on threats via text messaging — the content here is election related, but the tactic (bulk messaging w/lightly targeted text) has been exploiting && overloading text messaging for some time to enable phishing, scams, and political messaging.
Quote Tweet
My latest: Bulk text messaging — a tactic that's hard for individuals to filter, increasingly common, and impossible for authorities to monitor — is poised to be the new front for election disinformation: nbcnews.com/tech/security/

Especially this tweet. Any time you confuse ideology for analysis you set yourself up for blindspots and mistakes.
Quote Tweet
In that, realists and pacifists are not theoretical traditions. They are ideologies. They have already decided how the world works and if it might appear that the world doesn't work like they think it does, it's the world's problem, not the problem of their theories.

Excellent thread.

As Ukraine is making history with its counteroffensive, there's much witty sarcasm hurled at those who are being proved spectacularly wrong: those who predicted Ukraine's quick defeat at Russia's hands, urged territorial concessions to Russia, peace talks and West's abstention.🧵

It is very kind of the People's Republic of China to highlight the work of . While they are on our site, I would recommend this report on PRC influence operations attempting to whitewash massive human rights abuses in Xinjiang. stacks.stanford.edu/file/druid:sn4

A shocking study by Stanford Internet Observatory & research company Graphika found “an interconnected web of accounts” on Twitter&other social media platforms that “used deceptive tactics to promote pro-Western narratives...while opposing countries including Russia, China&Iran.”

Good thread and a reminder that making the occasional mistake is *good* — it means you’re pushing yourself and learning (god knows I’ve made plenty)! What’s important is processing the mistake, acknowledging it and learning from it!

So @wgetusername89 asked me this question in the DMs (which I'm sharing with permission) 👇 I think that the answer deserves a small 🧵since I was thinking about it for a long time. So, read the question and then read on! 1/7

It's also a powerful tool to illuminate real-world problems. Here just *telling* a fantastical story, and the (lame) criticism of it, highlights the abiding force of racism. Better to confront it then to pretend it doesn't exist. Good on you .

Sounds like they wanted cars to be secure by design. What do we need for that concept to be the norm in tech?
Quote Tweet
Something interesting I just learned: Volvo created and patented the 3-point seatbelt. And then gave it away so all cars could be safer. Something to think about when building security critical systems. caranddriver.com/news/a28775593
