A curated list of blogs posting threat intel.
This list is now very long. You can get a more manageable copy of the following table in a GSheet here.
Many feeds paths can be guessed when a standard blog framework is used. e.g by appending the following to the URL path;
/feed
/rss
Typically, but not always, feed URLs are also reported in the source code of the blog;
Right-click -> View Page Source -> Ctrl f atom
or rss
In some cases, blog categories have their own feeds so don't forget to check these if you only want a certain category of posts.
There are a ton of security blogs that don't offer RSS or ATOM feeds. I understand why (namely, concerns over copywrite), but don't necessarily agree with the reasons why.
Why?
There are tons of services that will create feeds from websites, Google; "create rss feed for a website".
For example; https://rss.app/, https://fetchrss.com/, are just a few examples.
I can't recommend any, but on cursory testing they appear to pretty good at creating live feeds for blogs and Twitter feeds.
