Here's the tl;dr - someone named "Md. Shofiur R" found troyhunt.com on a "free online malware scanner" and tried to scare me into believing my site had security vulnerabilities then shake me down for a penetration test. It didn't work out so well for him, here's the blow-by-blow account of things then I'll add some more thoughts afterwards: > Should I respond? ? pic.twitter.com/lifCZRcICF [https://t.co/lifCZRcICF] — Troy Hunt (@troyhunt) March 20, 2018 [https://twitter.com/troyhunt/status/9760...

Home again which means more time to blog and per the intro to this week's update, time to catch up on how HIBP is tracking. Here's the 2 tweets with some stats I mention at the start of this week's update: > It's been almost a month since I launched Pwned Passwords V2. In that time, @cloudflare [https://twitter.com/Cloudflare?ref_src=twsrc%5Etfw] has served 156TB from their cache thus keeping the traffic off my origin. Thanks guys, this would have been a hard discussion to have with the wife o...

There's no way to sugar-coat this: Have I Been Pwned [https://haveibeenpwned.com/] (HIBP) only exists due to a whole bunch of highly illegal activity that has harmed many individuals and organisations alike. That harm extends all the way from those in data breaches feeling a sense of personal violation (that's certainly how I feel when I see my personal information exposed), all the way through to people literally killing themselves [http://money.cnn.com/2015/09/08/technology/ashley-madison-suic...

Last day of travel! The weekly update is out late due to a packed week which I endured whilst battling a cold as well which has made it pretty rough. But other than that, it was a fantastic week recording Pluralsight courses and meeting with some really cool tech companies which I talk about in the update. I also talk a lot about credential stuffing which is just becoming an absolutely massive issue at present and I'll write more on that from home next week. I'll leave you with some pics of jus...

I'm in Seattle! This has been a mega week at the Microsoft MVP and Regional Director summits and as I say in the video, I'm actually a little run down now that it's all done. But I've had a wonderful week of meeting a heap of people and seeing some very cool stuff from Microsoft, especially around Azure which remains one of my favourite tech things. In this week's update, I'm talking about how I've made some further strong gains with Pwned Passwords which is being adopted at a pretty fierce rat...

Massive, massive week! I'm not trying to make these videos longer (and the next two while I'm overseas will definitely be shorter), but yeah, this week was a biggie. Pwned Passwords dominated throughout, interrupted only by a few thousand new data breaches going into HIBP. But the big one - at least to me in terms of the significance - is the UK and Aussie governments now using HIBP to monitor their gov domains. That's an absolute milestone in the service's history for many reasons, some of whic...

If I'm honest, I'm constantly surprised by the extent of how far Have I Been Pwned [https://haveibeenpwned.com/] (HIBP) is reaching these days. This is a little project I started whilst killing time in a hotel room in late 2013 after thinking "I wonder if people actually know where their data has been exposed?" I built it in part to help people answer that question and in part because my inner geek wanted to build an interesting project on Microsoft's Azure. I ran it on a coffee budget (the goal...

In the immortal words of Ricky Bobby, I wanna go fast [https://www.youtube.com/watch?v=_qJGsSuFRIg]. When I launched Pwned Passwords V2 last week [https://www.troyhunt.com/ive-just-launched-pwned-passwords-version-2/], I made it fast - real fast - and I want to talk briefly here about why that was important, how I did it and then how I've since shaved another 56% off the load time for requests that hit the origin. And a bunch of other cool perf stuff while I'm here. Why Speed Matters for Pwned...

tl;dr - a collection of nearly 3k alleged data breaches has appeared with a bunch of data already proven legitimate from previous incidents, but also tens of millions of addresses that haven't been seen in HIBP before. Those 80M records are now searchable, read on for the full story: There's an unknown numbers of data breaches floating around the web. There are data breaches we knew of but they just took years to appear publicly (Dropbox, LinkedIn), data breaches we didn't know of that also too...

Every now and then, I look at one of the videos I've just recorded and only realise then how tired I look. This was one of those weeks and it was absolutely jam-packed! There was some awesome stuff and there was some very frustrating stuff. Let me add briefly to the latter here: The joy of participating in online communities is that we have these melting pots of diverse backgrounds and ideas all coming together in the one place. A huge portion of what I've learned personally has come from very...
