We get it. We believe in online privacy and safety too. But please understand that by being on the public internet, we deal with people who try and abuse the tools of privacy & anonymity for nefarious purposes - in an automated manner at a vast scale.

There are a lot of (we think pretty cool) things you can do with WiGLE.net, and there are real-world costs that accompany offering those things. We're not in it for cash - it's a free site unless you're using it for commercial gain, then we ask you to keep help us keep the lights on.

We don't want donations (it's not like any of us are going to quit our day jobs) but we have to prune the "spikes" in usage of what we see as non-legitimate use/or violation of the EULA: for-profit without paying, download without proportionate contribution, and the hard-to-quantify "sketchy AF"

But dear internet: we've seen all the tricks. We're like a bouncer at the club. If we think you're not breaking the law, and will not be an a-hole once you're past the door, we WANT to let you in. Don't give us weird/awful/stupid reasons to not let you in. It's a community. It works because people.

I guess because like five of us are saying something, what was done to Chris Krebs is an absolute injustice and a mockery of his selfless service.

America no longer supports or protects critical infrastructure defenders. I hope someone else appreciates him a lot more.

I know he can’t reply.

I appreciate that so many are calling the "replace SSA COBOL systems in months using AI" idea out for the risk and difficulty inherent in replacing such a large and entrenched system.

We should also do a better job of articulating a key danger, which I'm sure the people expecting to pull this off don't understand: COBOL handles numbers and arithmetic in a way designed to maintain precision that is not supported natively by modern languages.

Two columns of numbers in 20 numbered rows, demonstrating a rounding problem exhibited by floating point numerical representations. The first column is labeled "floating point" and the second column is labeled "fixed point". In the first twelve rows, the numbers between the columns are very close both to each other and the number above. Starting at row 13 the floating point number deviates wildly before settling on a number two orders of magnitude off from where it started.

* 👾 Obscure Programming Languages in Malware: Malware authors are getting creative, using less common languages like Rust, Nim, Phix, Lisp and Haskell to evade detection - and it works.
* 💔 $8.2 Million Seized in Crypto Romance Baiting: The DOJ just seized millions in USDT from "romance baiting" scams (aka pig butchering), with links to human trafficking in Cambodia and Myanmar. This is a stark reminder of the human element in cybercrime.

@haveibeenpwned. But it isn't perfect. We ran into some issues with how scaling in Azure SQL HyperScale works, so I decided to write a blog post about it.

NEW: Google fixed three zero-day vulnerabilities in Android that were used by authorities to unlock phones with Cellebrite forensic tools.

The fixes come after Amnesty alerted Google, following the analysis of a Serbian student protester's phone.
