Except for phishing and scams, downloading an HTML attachment and opening it locally on your browser was never considered as a severe threat until a security researcher today demonstrated a technique that could allow attackers to steal files stored on a victim's computer. Barak Tawily, an application security researcher, shared his findings with The Hacker News, wherein he successfully developed a new proof-of-concept attack against the latest version of Firefox by leveraging a 17-year-old known issue in the browser. The attack takes advantage of the way Firefox implements Same Origin Policy (SOP) for the "file://" scheme URI (Uniform Resource Identifiers), which allows any file in a folder on a system to get access to files in the same folder and subfolders. Since the Same Origin Policy for the file scheme has not been defined clearly in the RFC by IETF, every browser and software have implemented it differently—some treating all files in a folder as the same...

A security researcher has discovered a critical vulnerability in Facebook Messenger that could allow an attacker to read all your private conversation, affecting the privacy of around 1 Billion Messenger users. Ysrael Gurt, the security researcher at BugSec and Cynet, reported a cross-origin bypass-attack against Facebook Messenger which allows an attacker to access your private messages, photos as well as attachments sent on the Facebook chat. To exploit this vulnerability, all an attacker need is to trick a victim into visiting a malicious website; that's all. Once clicked, all private conversations by the victim, whether from a Facebook's mobile app or a web browser, would be accessible to the attacker, because the flaw affected both the web chat as well as the mobile application. Dubbed " Originull ," the vulnerability actually lies in the fact that Facebook chats are managed from a server located at {number}-edge-chat.facebook.com, which is separate from...

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...
