Hey everyone! Just wanted to share that Immersive Labs has rolled out their "Haunted Halloween" challenges for 2023. For those unfamiliar, Immersive Labs offers a platform for interactive, gamified learning in the realm of cybersecurity. They've been known to host challenges that test and enhance cyber skills.

You can sign up for free using code HAUNTEDHOLLOW to try it out hubs.ly/Q026LTZV0.

Now, I'm not posting this solely out of altruism. I could use some help on the 'Mirrored Mayhem' task.

Would appreciate any pointers or hints from anyone who's tackled this challenge. Thanks in advance!

I saw people talking about YubiKey here a few weeks ago so I got curious. Unfortunately, I’m not seeing a lot of helpful reviews for it.

I’m personally getting tired of having to take my phone anytime I need 2FA for Okta but I don’t have a lot of super important accounts to secure so I’m going back and forth in deciding whether the 100+ euro investment (to get two so that there’s a duplicate) would be worth it.

How do you use your YubiKey in your personal life and do you think it’s worth your use case ?

As I'm exploring the idea of hosting my data at home (with offsite backups), I would like to better understand how to test my home network for security vulnerabilities.

I have run basic Nmap scans and confirmed that there are no open ports. I've confirmed that users have access to what they need but nothing else, and that guests using the network for web access don't have any sort of access to data. All data is encrypted so someone stealing the physical hardware shouldn't have access to the contents, either. But that's about as far as I know what to do.

What else could and should I try? How do you pentest your home network?

I feel I'm ok with my understanding of how to set things up so that everything is relatively secure. But I have very little idea how to actually test the setup.

Edit: Added a sentence about encryption.

I'm a little late on this, admittedly. $dayjob is requiring us all to set up a pair of YubiKeys, and I'm using them for the first time and my mind is a little blown.

I was seeing articles about "passkeys" all summer, not really grokking what they were talking about, clinging to my usernames and passwords and 2FA codes coming out of 1Password, etc.

I just set it up on a few accounts today, initially as an additional 2FA source, but when I set them on GitHub, I saw for the first time how exactly they are used instead of the username and password and 2FA combo to log in, and it seems incredible to me!

For long-time YubiKey users: what are some cool things in the ecosystem that you would recommend looking at?

It's seems to have been common sense for a while now that Windows has good-enough security software that you don't need 3rd party tools but is it actually the case now? Is there anything to lose or gain from trusting 3rd party with this stuff?
