Sending spammers to password purgatory
How best to punish spammers? I give this topic a lot of thought because I spend a lot of time sifting through the endless rubbish they send me. And that's when it dawned on me: the punishment should fit the crime - robbing me of my time - which means that
Oh, the Places Your Apple ID Will Go
Here is a short and curious Twitter thread from app developers and security researchers Tommy Mysk and Talal Haj Bakry: Apple’s analytics data include an ID called “dsId”. We were able to verify that “dsId” is the “Directory Services Identifier”, an ID that uniquely identifies an iCloud account. Meaning, Apple’s…

T oday is going to be the day that you read a lot about the UK’s intention to kill cookie pop-ups as part of its post-Brexit Data Reform Bill. By now you should have somehow realised that there’s a bit more to it than that, and that your work is not set to get any easier.

LogJ4 Security Inquiry – Response Required
On Friday January 21, 2022 I received this email. I tweeted about it and it took off like crazy. The email comes from a fortune-500 multi-billion dollar company that apparently might be using a product that contains my code, or maybe they have customers who do. Who knows? My guess is that they do this … Continue…

Scammers are using invoices sent through PayPal.com to trick recipients into calling a number to dispute a pending charge.

Who is squatting IPv4 addresses?
It’s an established fact on the internet that we have ran out of IP(v4) addresses , and we are starting to see the pressure on obtaining IPv4 space. For example if you want to get a /24 block from RIPE NCC when you sign up as a member, then you are currently looking at a 2 month wait for a recycled IPv4 /24 block .
Let's Encrypt now supports ACME-CAA: closing the DV loophole
Today, Let's Encrypt announced that they are enabling an extension to DNS CAA records known as ACME-CAA ( RFC 8657 ). This came as a surprise to me, but a very pleasant one, since I wrote the ACME-CAA specification back in 2016 with Let's Encrypt in mind, and it was finally published as RFC 8657 back in 2019. To my…
