You can detonate it into a VM running an instance of Cuckoo Sandbox. If you want to go the extra mile, you can dump the memory of said VM and analyse it with Volatility Framework. Also, if you want to quickly identify behavioural patterns in executable code, you can use Mandiant's CAPA tool (though idk if it works on .pdfs). Source: about 1 year ago

You should save a copy of the .exe, copy it into a VM running Cuckoo and get a report on exactly what the .exe does. Without this automated dissection, people are making educated guesses. They're probably right, but why not be certain? There is an online version too - https://cuckoosandbox.org. Source: about 1 year ago

You could use a service like cuckoo to check links/files. Source: over 1 year ago

I made my own lab in college using a series of VM's, A windows 10 machine that was packed with analysis tools, a kali listening machine (running inetsim or fakenet, I can't remember.) and I had remnux on another machine (which I ended up not really making use of, but it was there.) I used virtualbox and ran these VM's in an internal network, no internet access. Disabled all clipboard and file sharing after... Source: over 1 year ago

Another option if you want to self-host is https://cuckoosandbox.org/ . Of note, it's currently an unmaintained project so issues may not receive support, but it is free. Source: over 1 year ago

Glogg is a great tool, but unfortunately it is not developed anymore. I maintain a fork -- klogg (https://klogg.filimonov.dev). It is generally faster for both opening a file and performing searches. Current dev builds that use hyperscan regular expression engine can open a file and do a search while glogg would still be indexing that file. Source: about 2 years ago

Once I had to go through an unusually large log file which was around 2GB. I am a regular Notepad++ user but it couldn't handle the file. In addition to opening the file I also needed to search around the file for keywords like Error or Exception. I found klogg to be just the right tool for me. It allows for viewing as well searching for words within the large text file easily. - Source: dev.to / about 2 years ago

This is still an early stage TUI, many widgets are incomplete or missing (i.e. Text area, partial keyboard support, incomprehensible Documentation) I have very little time to work on it and the progresses are incredibly slow. I develop it in order to create a terminal log viewer that could mimic the features exposed by glogg or klogg. Source: over 2 years ago
