@TryHackMe I'm having an invoicing issue. The amount on my invoice is different from what got billed to my credit card and it's causing issues with my company's expense reporting.

“ValiDrive” New GRC Windows utility to quickly spot-check any USB mass storage drive for deliberate sizing fraud and errors: grc.com/validrive.htm Over the next day I'll be fleshing out its description page. But the Windows App is ready for the world now! 👍
@danielcranney I started out with Epsilon back in the early 90's and I still use it today. I used to work with a guy that actually wrote code in Wordstar.
@WhiskeyHackers I’m still working on your puzzle.
John Pfaff retweeted
GRC's forthcoming “ValiDrive” freeware is running and being tested by our terrific community. It IS finding bad, slow, buggy, error-prone and fraudulent USB drives. 👍 It's expected for release later this week. I'll announce it here when it's ready for everyone.
So the US govt has a site now for information on Unidentified Anomalous Phenomena (UAP) aaro.mil
@odinkai2112 @defcon @WhiskeyHackers It is gorgeous!
