Firefox Security Update | Breaking Cybersecurity News | The Hacker News

The critical Firefox vulnerability being actively exploited in the wild to unmask Tor users has been patched with the release of new browser updates. Both Mozilla and Tor Project has patched the vulnerability that allows attackers to remotely execute malicious code on Windows operating system via memory corruption vulnerability in Firefox web browser. Tor Browser Bundle is a repackaged version of the open-source Mozilla Firefox browser that runs connections through the Tor anonymizing network configured to hide its user's public IP address. However, the exploit code released by an unnamed online user was currently being exploited against Tor Browser users to leak the potentially identifying information of Tor users. "The security flaw responsible for this urgent release is already actively exploited on Windows systems," an official of the anonymity network wrote in an advisory published on Wednesday.  "Even though there is currently...no similar explo...

Earlier this week, Mozilla Security researcher Cody Crews discovered a malicious advertisement on a Russian news site that steals local files from a system and upload them to a Ukrainian server without the user ever knowing. The malicious advertisement was exploiting a serious vulnerability in Firefox's PDF Viewer and the JavaScript context in order to inject a script capable of searching sensitive files on user's local file systems . Mozilla versions of Firefox that do not contain the PDF Viewer, such as Firefox for Android, are not affected by the " Same origin violation and local file stealing via PDF reader " vulnerability. The exploit does not execute any arbitrary code but injects a JavaScript payload into the local file context, allowing the script to search for and upload potentially user's sensitive local files. All an attacker need to do is load the page with this exploit and sit back and relax. The exploit will silently steal files in t...

The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...
