7MS #459: Cyber News - Microsoft Exchange Makes the World Cry Edition

Happy mid-March! Our good pal Gh0sthax joins us today for another hot dish of cyber news! Stories include:

  • Microsoft Exchange cyber attack - Hacker News has a nice what we know so far story, but things have evolved really fast, so make sure you check Microsoft's primary advisory, the script to run on local servers and newer updates such as the recent one-click remediation for unsupported Exchange versions

  • SonicWall zero day - yuck, looks like the SonicWall troubles we talked about recently were a true zero day. In contrast to the Exchange story, it looks like SonicWall's official response offers (frighteningly?) little by way of logs and forensics to tell if you were truly popped. Either way, be sure to patch!

  • Hackers attempt to contaminate Florida town's water supply - the story itself is interesting, but the way it got picked up by some outlets seems to send the message of "TeamViewer = bad" but we think the true lessons learned here are:

    • Out of date and/or unsupported OS = bad
    • Weak credentials = bad
    • Connecting this type of equipment directly to the Internet instead of MFA + VPN = bad

CISA has a great breakdown of this incident as well.

7MS #622: Migrating from vCenter to Proxmox - Part 1

7MS #622: Migrating from vCenter to Proxmox - Part 1

Sadly, the Broadcom acquisition of VMWare has hit 7MinSec hard – we love running ESXi on our NUCs, but ESXi free is no longer available. To add insult to injury, our vCenter lab at OVHcloud HQ got a huge price gouge (due to license cost increase; not OVH's fault). Now we're exploring Proxmox as an alternative hypervisor, so we're using today's episode to kick off a series about the joys and pains of this migration process.

7MS #620: Securing Your Mental Health - Part 5

7MS #620: Securing Your Mental Health - Part 5

Today we're talking about tips to deal with stress and anxiety: It sounds basic, but take breaks – and take them in a different place (don't just stay in the office and do more screen/doom-scrolling) I've never gotten to a place in my workload where I go "Ahhh, all caught up!" so I should stop striving to hit that invisible goal. Chiropractic and back massages have done wonders for the tightness in my neck and shoulders For me, video games where you punch and kick things relieves stress as well (including a specific game that's definitely not for kids!)

We did something crazy today and recorded an episode that was 7 minutes long! Today we talk about some things that have helped us out in recent pentests: When using Farmer to create "trap" files that coerce authentication, I've found way better results using Windows Search Connectors (.searchConnector-ms) files This matrix of "can I relay this to that" has been super helpful, especially early in engagements

Hey friends, today we've got a tale of pentest pwnage that covers: Passwords – make sure to look for patterns such as keyboard walks, as well as people who are picking passwords where the month the password changed is part of the password (say that five times fast)!
