In part 2 of his #Exchange series, @chudypb describes the ApprovedApplicationCollection gadget. He also covers a path traversal in the Windows utility extrac32.exe, which allowed him to complete the chain for a full RCE in Exchange and remains unpatched.

I just got my hands on @tiraniddo's Windows Security Internals book <3

I ordered it through Blackwell's, that is a UK company but ships @nostarch books to EU too, so you can avoid dealing with customs yourself. Order tracking needs improvement.

I really try to like Firefox, but the last 5 minutes really captures the kind of papercut that happens often:

- I open a new tab and firefox informs me it has updated itself and needs to restart and won't allow any further operations until it does so.
- Fine, I close and restart.
- I reopen Firefox to find a brand new sponsored weather widget on my otherwise blank new tab page - from a source I would never otherwise visit.

Thanks for breaking my flow and the privacy breach, I guess.

We've completed a comparative security assessment of authorization policy languages: Cedar, Rego, and the OpenFGA modeling language.
If you are a language designer or a software developer, our AWS-sponsored assessment also provides recommendations for improving policy language design and for securing systems that use policy languages.

Are we not negative enough towards #ai

Australia really looked at GDPR and said “those fines are rookie numbers, mate”.

As @echo_pbreyer reminded us, EU member states have revived their effort to force-install a child pornography scanner on our phones again. This idea was rejected twice before, but they'll keep trying. Here's an English transcript of what I said about this in Dutch parliament last year: https://berthub.eu/articles/posts/client-side-scanning-dutch-parliament/

My SharePoint RCE got fixed: CVE-2024-38018. Site Member privs should be enough to exploit.

I also found a DoS vuln that got patched today: CVE-2024-43466.

It is shocking that after moving from Google workspace to Proton as the back office for our professional email adresses etc, all the major Dutch institutions are blocking us as spam. All our contacts have to whitelist us individually. So I think we are forced to go back to Google, where we had this problem occasionally but not as massively as now. It seems the reason is that Microsoft, used by almost all institutions in NL, simply blocks all Proton mail .😈 ( DNS=OK configured)
