yeahhhhhhhhhhhhhhhhhh
Haha, just for you!!!!
🎉❤ preach on
@@VickidYT thank you!
It's says mac size 650mb , what should I do?
If you suspect something is malicious, it’s safest to delete or not interact with it. This is especially true if VirusTotal confirms your suspicion.
So someone sent me an mp3 file via email (for work). I want to double check because I do not know this person. I often get work this way but this person came off as a bit "bot-like" this time. Can i download it and drop it into Virus Total before I download it? Or is there risk in even downloading it to begin with?
We'd recommend downloading it within a VM, and then uploading into Virustotal. That's just to be safe.
@@o-linesecurity7109 awesome thanks
Is 3/66 a virus?
If you mean 3 out of 66 detections, it could be, or maybe just a false positive, depends on the context. Still, some vendor flagged it as malicious.
Thanks!
Oh wow!!! Thank you so much! We really appreciate your gratitude, this means a lot to us. Thank you so much!
In ms 10 no messages are visible
Could you please elaborate?
Where do you get the labs? CompTIA?
Yep! You will have to order them from CompTIA's store.
please help it doesn't let me download it
Yes, unfortunately it doesn't seem like that image is available.

@@irvincharles7110 thank you!
Thanks for the guide! This seems like a really helpful tool. When you upload files to virus total are they visible to the other users of the site? It seems to say that they are at 4:23 but I wanted to check if I was misunderstanding. If the submissions you make are visible is there an alternate way to use virus total or an alternative tool that provides the same or similar functionality for files which have sensitive or private information e.g. when uploading a document which contains trade secrets of the business you work for that you're not allowed to publish, as a university professor maybe you want to check assignments submitted from hundreds of different students but don't want to share their work (especially with their name and student ID attached) without their permission on virus total, etc. Thanks again for the helpful guide.
Yep, when you upload files to VirusTotal, they can be visible to others, including security researchers and vendors. If privacy’s a concern (like for sensitive work or student assignments), VirusTotal Enterprise has a private scan option. Or check out tools like Hybrid Analysis (private mode) or Cuckoo Sandbox (self-hosted) for safer scanning. Hope that helps!
Nice, and thank you for good explanation.

This lab is different from the 1 I'm doing on compia
We took a quick look and noticed the main difference is just the order of the questions-nothing major! Take your time to go through the walkthrough first to get a clear understanding, and then return to the lab to complete it. You’ve got this-it’s all about taking it step by step!
Hey here is a link to the updated video ua-cam.com/video/2R6d3-7J2uw/v-deo.html
Thanks, very helpfull.
@@deysnobdansou You are very welcome!
Thank you! I’m really enjoying the video and learning a lot. Also, I wanted to ask for advice on how to get an internship in cybersecurity. Since I don’t have much experience, it’s been difficult to find a job.
Thank you for your kind words! We are so glad you’re enjoying the video and finding it helpful. 😊 Getting started in cybersecurity can be challenging, but one great way to build experience is by volunteering with companies or organizations in the field. Volunteering often opens doors and can sometimes be easier to get into than paid internships. We do have an internship program here, but it’s currently limited to O-Line Security students. Keep at it, though-your determination will pay off!
Amazing

What do you do when they login for Cam's password doesn't work and removes him as an admin? (Did I miss something?)
@@lynettemudie your best bet is to close and relaunch the lab!
Yeah I’m having this same issue
@@HalleysCommerce try redoing the lab, we’ve seen this fix the issue for most.
I decided to relaunch and the issue repeated itself, so I went into the previous PC, reset his password, however the admin issue was still present when I went into the cmd, so I used the admin user and password located on the resources tab, which allowed me to use cmd as an admin. Allowing me to finish the lab. It took some loop holes, but I made it! =)
