Hi! AIS detected UrlMal-inf[Trj] in several .PDFs and Phishing-VU[Phish] in a .HTM, and sent them to the chest.
Is it possible to read them through the Sandbox?
Thank you!

UrlMal-inf[Trj] in several .PDFs
Means those pdf.doc contain clickable links to blacklisted URLs

Thank you for your reply. Right, PDFs would be innocent text files if it wasn’t for those links. What I need is to just read the contents of moved files without clicking on their links. Maybe I would convert them to inert PNGs if I find them valuable.
What would be the steps to do that?
