The latest platform to fall victim to the relentless porting of the 1993 classic DOOM is the Portable Document Format, or PDF, developed by Adobe in 1992. Harnessing the built in JavaScript capabilities of the PDF format, high school student ading2210 took it upon themselves to get doom-ascii up...
If you view it on your system it’s a vector. Large / complex documents which may parse things with different libraries just happen to have a larger attack surface.
Yeah it does. Adobe has a lot of active script support, including java script for example, which can be exploited. If a software can’t interpret those scripts at all and simply displays plain text, that means malware won’t be executed.
And since Adobe Acrobat / Acrobat Reader are the most common pdf viewers out there, they are a natural target for hackers as well.
I genuinely don’t know, I have set my browser to download pdfs by default and only open them with Sumatra. There might be a scripting layer active in the browser as well though, quite possible.
Anti adobe is cool - the recommendation is appreciated… but any software can be the target of a document based exploit and may well be susceptible to the same exploit depending on the libraries used. Additionally, smaller software projects can take longer to update as they have less staff working on them. Absolutely support open software and alternatives… Just a word of caution.

PDFs have been an attack vector for a while actually.

One more reason never to use the official adobe software. SumatraPDF is awesome. Barebones and blazing fast.
I don’t think it has to do with opening a PDF in Adobe, but okay.

Is Acrobat the only pdf reader with active script support? For example, do the common browsers which can also open pdfs not support the same things?

Then would you agree that it doesn’t have to do with Adobe Acrobat, as much at it does active script in PDFs and if the reader executes it?
