Simple Exploit Allows Attackers to Modify Email Content — Even After It's Sent!

Simple Exploit Allows Attackers to Modify Email Content — Even After It's Sent!

Aug 23, 2017
Security researchers are warning of a new, easy-to-exploit email trick that could allow an attacker to turn a seemingly benign email into a malicious one after it has already been delivered to your email inbox. Dubbed Ropemaker (stands for Remotely Originated Post-delivery Email Manipulation Attacks Keeping Email Risky), the trick was uncovered by Francisco Ribeiro, the researcher at email and cloud security firm Mimecast. A successful exploitation of the Ropemaker attack could allow an attacker to remotely modify the content of an email sent by the attacker itself, for example swapping a URL with the malicious one. This can be done even after the email has already been delivered to the recipient and made it through all the necessary spam and security filters, without requiring direct access to the recipient's computer or email application, exposing hundreds of millions of desktop email client users to malicious attacks. Ropemaker abuses Cascading Style Sheets (CSS) and Hyp...

Yahoo Disables Email Auto-Forwarding; Making It Harder for Users to Move On

Oct 11, 2016
Yahoo! has disabled automatic email forwarding -- a feature that lets its users forward a copy of incoming emails from one account to another. The company has faced lots of bad news regarding its email service in past few weeks. Last month, the company admitted a massive 2014 data breach that exposed account details of over 500 Million Yahoo users. If this wasn't enough for users to quit the service, another shocking revelation came last week that the company scanned the emails of hundreds of millions of its users at the request of a U.S. intelligence service last year. That's enough for making a loyal Yahoo Mail user to switch for other rival alternatives, like Google Gmail, or Microsoft's Outlook. Yahoo Mail Disables Auto-Forwarding; Making It Hard to Leave But as Yahoo Mail users are trying to leave the email service, the company is making it more difficult for them to transition to another email service. That's because since the beginning of Octob...

Want to Grow Vulnerability Management into Exposure Management? Start Here!

Dec 05, 2024Attack Surface / Exposure Management
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...
