I was recently cleaning off someone's Mac and made this note: > I found no fewer than eight fake Adobe Flash updaters, six of them identical and signed by Nevaeh Mitchell (WMAA75SZMS), one signed by Lambert Jeremy (B4MCPEJ42J), and one by Wolfe Bailey (3W8NF7PWUL). It does not appear that Apple has revoked any of these signing certificates or flagged any of these installers through macOS's built-in malware removal tools. So it doesn't seem to me that malware authors are exactly afraid of signing requirements.
