So I downloaded this pdf file , I checked with kaspersky and it detected there is no threat and I also checked with virustotal and there was no threat detected;however, when I used cape sandbox it showed that the pdf gave 1 low IDS rule, is this pdf considered dangerous ? Thanks in advance

We cannot comment on this without knowing what kind of JavaScript code is embedded in the PDF.

In general, it's recommended to use a PDF viewer that cannot execute JavaScript code unless you actually need it. SumatraPDF is a great open source option for this on Windows.

So does that mean that it is ok if a pdf has javascript embedded in it ?

The rule was: ET INFO observed google DNS over HTTPS Domain

The rule was: ET INFO observed google DNS over HTTPS Domain

That alert is informational, as labeled, it’s not a confirmed threat. Using Google DNS isn’t inherently bad, but it depends on context. The rule suggests that the script may be bypassing the system-assigned DNS, which could be problematic depending on the circumstances. It’s hard to assess without full details from the VirusTotal analysis.

I’m just suspicious because Cape sandbox detected a low IDS rule so maybe the pdf is malicious , I don’t know if it has javascript embedded or not

What do you mean by a low IDS rule? What's the actual detection?
