"We'll publish critical vulnerabilities in PGP/GPG and S/MIMEemail encryption on 2018-05-15 07:00 UTC". Encrypting messages is still safer than not encrypting them-EFAIL basically just lets attackers read messages they've already compromised in some other way-but it's still not enough to truly protect the contents of those emails. By also including the Web address of an attacker-controlled server, the newly sent emails can cause the programs to send the corresponding plaintext to the server.
They continue that in their model, the attacker is able to collect end-to-end encrypted emails, either through a man-in-the-middle attack on the network, by accessing a SMTP server, by accessing the IMAP account on the server, or by some other means.
The security flaw may also also represent more of a problem with PGP implementation than any bug with the encryption standard.
Indeed, El Regrecommends opening PGP-encrypted emails in a text editor on a secured virtual machine, host, or container, depending on your level of paranoia, rather than allow encrypted HTML messages to be parsed and rendered.
According to the researchers, EFAIL affects clients that use a graphical user interface, including Thunderbird with Enigmail, Apple Mail with GPGTools and Outlook with Gpg4win.
"It's a lot of steps for sure, and one that honestly is more hypothetical than is it is unsafe", Dave Kennedy, the chief executive at security company TrustedSec, said. By injecting malformed images or styling resources into encrypted plaintext, the attacker has a one in three chance of success at decoding the remainder of the target email.
The researchers clearly state: "The Efail attacks require the attacker to have access to your S/MIME or PGP encrypted emails".
Experts contacted by the human rights organisation "electronic frontier Foundation", which has published instructions for disabling the encryption in the email. The PGP CFB gadget attack was assigned CVE-2017-17688, while the S/MIME CBC vulnerability was given CVE-2017-17689.
"This is bad because the people who use PGP use it for a reason", he told the BBC.
Anyone who actively wants their email communication to be secure and private - and uses common email security plugins - should take notice.
"EFF has been in communication with the research team, and can confirm that these vulnerabilities pose an immediate risk to those using these tools for email communication, including the potential exposure of the contents of past messages", the organization says in a blog post.
