Over Dozen Popular Email Clients Found Vulnerable to Signature Spoofing Attacks

Over Dozen Popular Email Clients Found Vulnerable to Signature Spoofing Attacks

Apr 30, 2019
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
Researchers Crack 1024-bit RSA Encryption in GnuPG Crypto Library

Researchers Crack 1024-bit RSA Encryption in GnuPG Crypto Library

Jul 04, 2017
Security boffins have discovered a critical vulnerability in a GnuPG cryptographic library that allowed the researchers to completely break RSA-1024 and successfully extract the secret RSA key to decrypt data. Gnu Privacy Guard (GnuPG or GPG) is popular open source encryption software used by many operating systems from Linux and FreeBSD to Windows and macOS X. It's the same software used by the former NSA contractor and whistleblower Edward Snowden to keep his communication secure from law enforcement. The vulnerability, labeled CVE-2017-7526 , resides in the Libgcrypt cryptographic library used by GnuPG, which is prone to local FLUSH+RELOAD side-channel attack. A team of researchers — from Technical University of Eindhoven, the University of Illinois, the University of Pennsylvania, the University of Maryland, and the University of Adelaide — found that the "left-to-right sliding window" method used by the libgcrypt library for carrying out the mathematics o
GenAI: A New Headache for SaaS Security Teams

GenAI: A New Headache for SaaS Security Teams

Apr 17, 2024SaaS Security / AI Governance
The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

GnuPG Email Encryption Project Relies on 'Werner Koch', and He is Running Out of Funds

Feb 06, 2015
Werner Koch , the man who authored the free email encryption software , is running out of funding to continue the development of his crucial open-source GNU Privacy Guard (GnuPG) encryption tools.The code works on plenty of operating systems from Linux and FreeBSD to Windows and OS X. The popular Gnu Privacy Guard (GnuPG or GPG) email encryption software is the same used by the former United States National Security Agency (NSA) contractor and whistleblower Edward Snowden to keep his communication secure from law enforcement authorities. GPG uses the OpenPGP standard to safeguard the communications of millions of people, including journalists, dissidents and security-minded people, around the world from eavesdroppers and other miscreants. GPG EMAIL ENCRYPTION RELIES ON THIS GUY ONLY Werner Koch has been maintaining and improving the code of his own secure email software since its initial development in 1997, and since then he has worked at very low wages, but is now
