Adobe
The first data breach I noticed using the CatchAll-E-Mail Adress was with Adobe in 2013. I contacted Adobe, that I receive emails to adobe@catchall and if there was any data breach. Adobe never responds to my E-Mail.
Several months later information surface, that the day a breach was considered the largest data a breach at this time. Today, after data breaches with Equifax or Walmart, 38 Million datasets did not sound much anymore.
