Ask HN: What are some advanced fact check strategies

I have been reading a lot of technology news lately from diverse sources and observed some patterns that are easy to verify - outdated info presented as news, misleading title, etc. On the other hand, some news pieces look credible but when I start to verify it leads to a dead-end (or at least nothing that wouldn't take hours to verify). Google's fact-check tool seems to work only on old and popular news only.

The case in point right now, this article: https://techxplore.com/news/2025-07-vulnerability-packet-paralyze-smartphones.html

* I did not find any other reputed source linking back to this article. * The site has decent domain authority. * Searched the publishing institute (KAIST) website with google search (https://www.google.com/search?q=LLFuzz+RCE+site:https://www.kaist.ac.kr/) and did find the original article (likely the original source)

So far so good. But the concerns are

1. Is this enough fact-checking, what other techniques am I missing? 2. This whole process takes time, are there any other known techniques/tools to further reduce the time to fact-check and analyze
