Here's How eFail Attack Works Against PGP and S/MIME Encrypted Emails

Here's How eFail Attack Works Against PGP and S/MIME Encrypted Emails

May 14, 2018
With a heavy heart, security researchers have early released the details of a set of vulnerabilities discovered in email clients for two widely used email encryption standards—PGP and S/MIME—after someone leaked their paper on the Internet, which was actually scheduled for tomorrow. PGP and S/MIME are popular end-to-end encryption standards used to encrypt emails in a way that no one, not even the company, government, or cyber criminals, can spy on your communication. Before explaining how the vulnerability works, it should be noted that the flaw doesn't reside in the email encryption standards itself; instead, it affects a few email clients/plugins that incorrectly implemented the technologies. Dubbed eFail by the researchers, the vulnerabilities, as described in our previous early-warning article , could allow potential attackers to decrypt the content of your end-to-end encrypted emails in plaintext, even for messages sent in the past. According to the paper released
Lavabit — Encrypted Email Service Once Used by Snowden, Is Back

Lavabit — Encrypted Email Service Once Used by Snowden, Is Back

Jan 21, 2017
Texas-based Encrypted Email Service ' Lavabit ,' that was forced to shut down in 2013 after not complying with a court order demanding access to SSL keys to snoop on Edward Snowden's emails , is relaunching on Friday. Lavabit CEO Ladar Levison had custody of the service's SSL encryption key that could have helped the government obtain Snowden's password. Although the FBI insisted it was only after Snowden's account, that was the key to the kingdom that would have helped the FBI agents obtain other users' credentials as well. But rather than complying with the federal request that could compromise the communications of all of its customers, Levison preferred to shut down his encrypted email service, leaving its 410,000 users unable to access their email accounts. Now, Levison has announced that he is reviving Lavabit with a new architecture that fixes the SSL problem — which according to him, was the biggest threat — and includes other privacy-enhancin
How to Increase Engagement with Your Cybersecurity Clients Through vCISO Reporting

How to Increase Engagement with Your Cybersecurity Clients Through vCISO Reporting

Jul 22, 2024vCISO / Business Security
As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.
What is SMTP STS? How It improves Email Security for StartTLS?

What is SMTP STS? How It improves Email Security for StartTLS?

Mar 24, 2016
Despite so many messaging apps, Email is still one of the widely used and popular ways to communicate in this digital age. But are your Emails secure? We are using email services for decades, but the underlying 1980s transport protocol used to send emails, Simple Mail Transfer Protocol (SMTP), is ancient and lacks the ability to secure your email communication entirely. However, to overcome this problem, SMTP STARTTLS was invented in 2002 as a way to upgrade an insecure connection to a secure connection using TLS. But, STARTTLS was susceptible to man-in-the-middle attacks and encryption downgrades. But worry not. A new security feature is on its way!!! SMTP STS: An Effort to Make Email More Secure Top email providers, namely Google, Microsoft, Yahoo!, Comcast, LinkedIn, and 1&1 Mail & Media Development, have joined forces to develop a new email standard that makes sure the emails you send are going through an encrypted channel and cannot be sniffed. Dubbed SMT

The Best Way to Send and Receive End-to-End Encrypted Emails

The Best Way to Send and Receive End-to-End Encrypted Emails

Mar 18, 2016
How many of you know the fact that your daily e-mails are passaged through a deep espionage filter? This was unknown until the whistleblower Edward Snowden broke all the surveillance secrets, which made privacy and security important for all Internet users than ever before. I often get asked "How to send encrypted email?", "How can I protect my emails from prying eyes?" and "Which is the best encrypted email service?". Although, there are a number of encryption tools that offers encrypted email service to ensure that no one can see what you are sending to someone else. One such tool to send encrypted emails is PGP ( Pretty Good Privacy ), an encryption tool designed to protect users' emails from snooping. However, setting up a PGP Environment for non-tech users is quite a difficult task, so more than 97% of the Internet users, including government officials, are still communicating via unencrypted email services i.e. Gmail, Ya
Encrypted Email Servers Seized by German Authorities After School Bomb Threats

Encrypted Email Servers Seized by German Authorities After School Bomb Threats

Dec 22, 2015
In the wake of a hoax bomb threat, all public schools in Los Angeles were closed for a day last week, and now German authorities have seized an encrypted email server. But, Does that make sense? In a video statement posted on Monday, the administrator of Cock.li – an anonymous email provider service – said German authorities had seized a hard drive from one of its servers that used to host the service in a Bavarian data center. The email provider was thought to have been used last week to send bomb threatening emails to several school districts across the United States, resulting in the closure of all schools in the Los Angeles Unified School District. Despite The New York City Department of Education dismissed the e-mail as an obvious hoax, German authorities seized a hard drive that, according to the service admin, actually holds "all data" on the company. According to the service administrator Vincent Canfield, "SSL keys and private keys and f
ProtonMail Paid Hackers $6000 Ransom in Bitcoin to Stop DDoS Attacks

ProtonMail Paid Hackers $6000 Ransom in Bitcoin to Stop DDoS Attacks

Nov 06, 2015
The Geneva-based encrypted email service ProtonMail was forced to pay a  Ransom of almost $6,000 to stop sustained Denial-of-service (DDoS) attacks that have knocked its service offline since Tuesday. ProtonMail – a full, end-to-end encrypted email service that launched last year – has been dealing with, what it called, the extremely powerful DDoS attack, and is still unavailable at the time of writing. ProtonMail Paid $6,000 to Stop DDoS In an official statement posted on a WordPress blog Thursday, officials of ProtonMail said the powerful DDoS attack by an unknown group of hackers forced them to pay 15 Bitcoins (about $5,850) in exchange for them halting the assault. However, even after paying the ransom amount, the crippling DDoS attacks continued to the ProtonMail service. DDoS Attack Continues Even After Paying Ransom ProtonMail officials said, "We hoped that by paying [ransom], we could spare other companies impacted by the [DDoS] attack again
