It&#x27;s worth noting that there&#x27;s basically zero proper evidence that there is any malware included with this device -- it runs an exe when inserted, but that exe appears, at a glance, to be a driver installer. Definitely not the right way to do things, but there&#x27;s a difference between &quot;incompetent&quot; and &quot;malicious&quot;.<p>The only actual &quot;evidence&quot; that was provided was a link to a falcon sandbox run, something which actually requires human analysis to draw conclusions about -- and anyone who has ever used it <i>knows</i> how many false positives it finds.<p>A better proclamation might be &quot;cheap network adapter comes with an auto-running executable which needs further analysis&quot;.

Seems light on details. How is it executing the payload? Is it doing something like badusb where it emulates a keyboard to run the payload? Wouldn&#x27;t that be super obvious? Or is it something as simple as telling the user to install a &quot;driver&quot;?

I liked the graceful admission of error too: <a href="https:&#x2F;&#x2F;x.com&#x2F;evapro30&#x2F;status&#x2F;1880123024474796107" rel="nofollow">https:&#x2F;&#x2F;x.com&#x2F;evapro30&#x2F;status&#x2F;1880123024474796107</a>

Twitter is terrible and I can&#x27;t remember the nitter instance that still works.

It ain&#x27;t just twitter that has armchair experts that are rude. Most social media sites allow this behavior. So many replies with horrible posts &quot;your doing it wrong&quot;, &quot;read the docs&quot;, etc.<p>I&#x27;ve seen so many correct responses downvoted and with horrible replies. Anyone who used old moderated email lists will see how culture changed and the decline of actual conversation. Even stack overflow has went downhill.
