email clients | Breaking Cybersecurity News | The Hacker News

A team of security researchers has discovered several vulnerabilities in various implementations of OpenPGP and S/MIME email signature verification that could allow attackers to spoof signatures on over a dozen of popular email clients. The affected email clients include Thunderbird, Microsoft Outlook, Apple Mail with GPGTools, iOS Mail, GpgOL, KMail, Evolution, MailMate, Airmail, K-9 Mail, Roundcube and Mailpile. When you send a digitally signed email, it offers end-to-end authenticity and integrity of messages, ensuring recipients that the email has actually come from you. However, researchers tested 25 widely-used email clients for Windows, Linux, macOS, iOS, Android and Web and found that at least 14 of them were vulnerable to multiple types of practical attacks under five below-mentioned categories, making spoofed signatures indistinguishable from a valid one even by an attentive user. The research was conducted by a team of researchers from Ruhr University Bochum and

If you receive an email that looks like it's from one of your friends, just beware! It's possible that the email has been sent by someone else in an attempt to compromise your system. A security researcher has discovered a collection of vulnerabilities in more than 30 popular email client applications that could allow anyone to send spoofed emails bypassing anti-spoofing mechanisms. Discovered by security researcher Sabri Haddouche , the set of vulnerabilities, dubbed MailSploit , affects Apple Mail (macOS, iOS, and watchOS), Mozilla Thunderbird, several Microsoft email clients, Yahoo Mail, ProtonMail, and others. Although most of these affected email client applications have implemented anti-spoofing mechanisms, such as DKIM and DMARC, MailSploit takes advantage of the way email clients and web interfaces parse "From" header. Email spoofing is an old-school technique, but it works well, allowing someone to modify email headers and send an email with the fo
