DESCRIPTION:One from the vaults. In 2020\, Justin had a serendipitous encou
 nter with a dangling legacy AWS S3 bucket once owned by the Linux Vendor F
 irmware Service (LVFS). "What if I registered it\," he thought. "What's th
 e worst that could happen?" This is the story of how he wedged himself bet
 ween 100\,000 Linux machines and their firmware updates\, stumbled upon a 
 bypass in fwupd's PGP-based firmware update signature checking\, traced th
 e flaw back to its root cause\, and ultimately returned the bucket to its 
 original owner.

SUMMARY:"Well well well\, if it isn’t the consequences of my own actions"
  - the time I got in the middle of 100\,000 Linux machines and their fwupd
 /LVFS firmware updates 🙈 - Justin Steven
