ENIGMAIL | Breaking Cybersecurity News | The Hacker News

A security researcher has discovered a critical vulnerability in some of the world's most popular and widely used email encryption clients that use OpenPGP standard and rely on GnuPG for encrypting and digitally signing messages. The disclosure comes almost a month after researchers revealed a series of flaws, dubbed eFail , in PGP and S/Mime encryption tools that could allow attackers to reveal encrypted emails in plaintext , affecting a variety of email programs, including Thunderbird, Apple Mail, and Outlook. Software developer Marcus Brinkmann discovered that an input sanitization vulnerability, which he dubbed SigSpoof , makes it possible for attackers to fake digital signatures with someone's public key or key ID, without requiring any of the private or public keys involved. The vulnerability, tracked as CVE-2018-12020 , affects popular email applications including GnuPG, Enigmail, GPGTools and python-gnupg, and have now been patched in their latest available so...

Constant password breaches and Snowden revelations about Government Surveillance have raised many questions that why don't cloud and email Services encrypt the data stored on their server?  Revelations forced the popular Internet Giants such as Google and Yahoo to contemplate on the privacy and security issues and in response companies started enhancing their encryption standard by enabling HTTPS by default and removed the option to turn it off. A few days back, Google admitted that their automated systems read your content, including incoming and outgoing emails to provide you personally relevant advertisements. That means Internet giants generally do encrypt your data, but they have the key so they can decrypt it any time they want. Encryption is mandatory in Modern Internet and web services should consider Encrypting and decrypting your data locally, so that no one can snoop on. Such cryptographic mechanism is called End-to-End Encryption , ...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

In my last article, we have learnt that how to encrypt our Emails using Gnu Privacy Guard . Previously we used Microsoft Outlook as a desktop mail client and a GpgOL plugin to handle encryption decryption of our communication. Since Microsoft is a US-based company, that has to follow all the laws of that contingent. Should we trust Microsoft product to save our e-mail password and data? Obviously NO!  This made me write a new article on the same topic is that today we are going to use an open source mail client i.e.  Mozilla Thunderbird , available for Windows, Mac OS X and Linux. Thunderbird Installation: Initially you need to download the Thunderbird mail client, and install it to make your email communication more secure and private. Open Thunderbird tool and configure your mail account, as shown: Installing and Configuring ENIGMAIL:  In the next step you need to install an Add-on in Thunderbird, called  ENIGMAIL . You can search and install add-on using...
