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

Hands-on Review: Cynomi AI-powered vCISO Platform
Apr 10, 2024vCISO / Risk Assessment
The need for vCISO services is growing. SMBs and SMEs are dealing with more third-party risks, tightening regulatory demands and stringent cyber insurance requirements than ever before. However, they often lack the resources and expertise to hire an in-house security executive team. By outsourcing security and compliance leadership to a vCISO, these organizations can more easily obtain cybersecurity expertise specialized for their industry and strengthen their cybersecurity posture. MSPs and MSSPs looking to meet this growing vCISO demand are often faced with the same challenge. The demand for cybersecurity talent far exceeds the supply. This has led to a competitive market where the costs of hiring and retaining skilled professionals can be prohibitive for MSSPs/MSPs as well. The need to maintain expertise of both security and compliance further exacerbates this challenge. Cynomi, the first AI-driven vCISO platform , can help. Cynomi enables you - MSPs, MSSPs and consulting firms

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

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
