Some exploits are just three curl commands in a trench coat.

I FOUND IT.
it took nearly four hours, but i found it.

thank you for coming along with me into the mines of my twitter archive to find this gif. dropbox deleted this, and many others when they 'just decided' to delete all locally stored files, making all the stuff you had exist only in the cloud.

i fired them for this, and replaced them with synology drive, that I sync over wireguard.

A colleague just wanted to gift me an InkJet...

Mozilla, reading the room extremely well, seemingly just recently flipped the switch to enable-by-default sponsored weather results from AccuWeather in every new Firefox tab you open. Clicking "Learn more" takes you here, with zero information on if your location is sent to AccuWeather every time you open a new tab: https://support.mozilla.org/en-US/kb/customize-items-on-firefox-new-tab-page

Probably only noticed because I normally have a blank new tab page but this showed up after updating Firefox!

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.
