If you currently use email to communicate with clients via PGP/GPG or S/MIME for encryption, those emails may not be secure.
However, while several critical vulnerabilities were discovered in email, technology experts are saying don’t panic.
The Electronic Frontier Foundation (EFF) recommends users disable and/or uninstall tools that automatically decrypt PGP-encrypted email and/or use alternative end-to-end secure channels. Experts also recommend including client disclaimers in lawyer emails. EFF reports that this is a temporary stopgap until more information is publicly available and known.
