First and foremost, I have to say that 7 Minute Security's official stance on toads is that nobody should be licking them at any time, for any reason. Also, I can neither confirm nor deny that toads can catch coronavirus. Listen to today's episode...it'll make more sense.

We've got another swell tale of internal pentest pwnage for you today! Highlights include:

• If you've collected a ton of hashes with Responder, the included DumpHash.py gives you a lovely organized list of collected hashes!

• Here's one way you can grab the latest CME binary:

curl https://github.com/byt3bl33d3r/CrackMapExec/releases/download/v5.0.1dev/cme-ubuntu-latest.zip -L -o cme.zip

Note to self: I must've been using outdated CME forever, because the correct syntax to get the wdigest flag is now a little different:

cme smb HOST -u localadmin -H "hash" --local-auth -M wdigest -o ACTION=enable

• If you're looking to block IPv6 (ab)use in your environment, this article has some great tips.

• When testing in an environment with a finely tuned SIEM, I highly recommend you download all the Kali updates and tools ahead of time, as sometimes just the call out to kali.org gets flagged and alerted on to the security team

• Before using the full hatecrack methodology, I like to run hashes straight through the list of PwnedPasswords from hashes.org (which appears to currently be offline) first to give the org an idea as to what users are using easy-to-pwn passwords.

• A question for YOU reading this: what's the best way to do an LSASS dump remotely without triggering AV? I can't get any of the popular methods to work. So pypykatz is my go-to.

• I learned that PowerView is awesome for finding attractive shares! Run it with Find-InterestingDomainShareFile to find, well, interesting files! Files with password or sensitive or admin in the title - and much more!

• Got to use PowerUpSQL to audit some MS SQL sauce, and I found this presentation (specifically slide ~19) really helpful in locating servers I could log into and any SQL vulnerabilities the boxes were ripe for.
