Quick tip. If you're trying to download really old versions of macOS, they're hard to find (e.g., El Capitan, etc.). You can find lots of dodgy sites that you don't want to deal with, but it's hard to find legit Apple web sites. The trick is to search for "enterprise". Then you can find pages like this, which has a legit link to an Apple DMG. https://support.apple.com/en-us/HT206886

One of the more obscure and least understood #security principles is "psychological acceptability." Nobody spends any time on it. Just google a phrase and see that everyone plagiarizes everyone else. Search for "principle that aims at maximizing the usage and adoption of the security functionality"

I have just used "Why is Gamora" to answer a customer question about TLS certificates. That's probably the high point of my week. :)

Some people might call this "parody". In my world, it's a bit more like "Tuesday". https://www.youtube.com/watch?v=JMOOG7rWTPg

I had a non-delivery notification from my personal mail server to outlook.com. It said "your ISP's network is on our block list.' My ISP is AWS and the network is a /14. It's bonkers.

It's like living in a 500-unit apartment complex and a company says "unit 402 didn't pay for their purchases last month, so we're not selling anything to anyone in that complex any more."

Green text, meet red text. Red text, meet green text. Now that you guys are acquainted, would you like to go off, have a little chat, and come back to me with a USEFUL error message?

If you have some spare compute cycles and you want to donate them to fighting #covid19, there's a medical research programme called "Folding@Home" which is similar to SETI@Home, but for medical research: https://foldingathome.org/2020/03/15/coronavirus-what-were-doing-and-how-you-can-help-in-simple-terms/

This is a fascinating C2 vector. But I gotta admit: it's hard to take it seriously with this diagram. https://news.sophos.com/en-us/2020/02/25/cloud-snooper-attack-bypasses-firewall-security-measures/

Not mine. But absolutely appropriate for this forum. :) #infosec

That’s big news. #OpenSSH adds support for Fido/U2F tokens. https://www.zdnet.com/article/openssh-adds-support-for-fidou2f-security-keys/

I wrote a blog post on how to use KMS key policies to act as a separate access control for data in Amazon S3. https://aws.amazon.com/blogs/security/how-to-use-kms-and-iam-to-enable-independent-security-controls-for-encrypted-data-in-s3/

I see a lot of articles say things like "They now run this service in the cloud—which brings its own set of security challenges." I wish they would equivalently write "They run their IT in their own data centres—which brings its own set of security challenges."

DIY infrastructure? Oh that's obviously secure. Professionally-run commercial clouds? Whoa, they're risky.

The physical affects the virtual affects the physical. Performance artist creates virtual traffic jams by pulling a wagon full of second-hand phones all using Google maps app. http://www.simonweckert.com/googlemapshacks.html

Why do #infosec people go around insulting everyone? Everyone who uses the cloud "blindly trust the cloud providers"? Nobody is doing due diligence? Nobody has a long list of security risks they track and controls and mitigations, huh? And they want to "disprove the assumption that cloud infrastructures are secure". Because the existence of one bug means what? It's "insecure"? The research is legit, but the preamble is garbage from an out-of-touch techie. https://research.checkpoint.com/2020/remote-cloud-execution-critical-vulnerabilities-in-azure-cloud-infrastructure-part-i/

I just had the song “Memories” from “Maroon 5” come up on my play list. Listen to it for about 10 seconds. I can’t believe a modern band can get away with that.

YouTube’s copyright bots have filed a claim against a video I did in 2017. It asserts that I am infringing on a video copyrighted in 2020. Not really sure how that is possible and why they don’t, instead, think that the newer person is infringing on ME. Pain in the ass. I hate YouTube.
