Some spam just makes you shake your head... what are they selling? IoT parenting solutions? There is an "Infant Industry"??

16 years ago, I started the daily SANS Internet Storm Center Stormcast. Over 16 years, I recorded about 3,900 episodes and 26,000 minutes of content (sounds more impressive than 16 days :) ).

Subscribe to it wherever you find podcasts. (or Alexa Flash Briefings, YouTube)

Just noted this fun memorabilia in my GIAC certification history. Who remembers Track 1 ? Also got a Track 2 (Firewalls) ;-)

First time seeing this, one day before the expected TikTok shut down. Final attempts to monetize soon to be obsolete scripts? Anything else behind these obvious scams?

Is anybody else getting spam like this from "academia.com"? The reason I call it spam is that (a) I probably didn't mention myself on a platform I am not using (b) the only way to see what I said about myself requires $5.

I am aware of similar platforms like Researchgate and am using them.
