10 dangerous app vulnerabilities to watch out for (free PDF)Stop 100 of ransomware, phishing malware, and zero-days from reaching - and infecting - endpoints and networks. BenefitsSoftwareedit WebCatalog (macOS/Windows/Linux, isolated cookie storage) Chromeless (macOS, isolated cookie storage) Fluid (Mac OS X only, isolated cookie. This web browser isolation software allows users to securely visit possibly dangerous websites without compromising the hardware, instead of diverting the risk into the browser isolation software itself. Browser isolation software is browser software that allows users to access websites through a virtual remote desktop software web browser that has secure endpoints.
![]() Browser Lation Code Would TriggerWhen a user accessed the malicious site, the exploit code would trigger, and extract data from other sites that had been stored inside Chrome.Now that Site Isolation was expanded to detect and stop such attacks, Google says this won't be possible anymore, as each site's data (such as cookies and passwords) will be site-locked, and moved in a separate Chrome process altogether.Memory and UXSS bugs that could bypass SOP won't be useful anymore. Attackers usually placed malicious code on sites that exploited these types of vulnerabilities. "Site Isolation can now handle even severe attacks where the renderer process is fully compromised via a security bug, such as memory corruption bugs or Universal Cross-Site Scripting (UXSS) logic errors."Memory bugs and UXSS vulnerabilities have been used in the past. Protection against more attacks on desktopBut while Site Isolation is taking its first steps on smartphones, the feature is expanding on desktops.According to Google, starting with Chrome 77 released last month, Site Isolation on desktops can protect users against more exploit types than the original support for side-channel (Spectre-like) attacks."Our initial launch targeted Spectre-like attacks which could leak any data from a given renderer process," Google engineers said today.Resources labeled with a Cross-Origin-Resource-Policy header are also protected. Network data: Site Isolation uses Cross-Origin Read Blocking to filter sensitive resource types (e.g., HTML, XML, JSON, PDF) from a process, even if that process tries to lie to Chrome's network stack about its origin. Authentication: Cookies and stored passwords can only be accessed by processes locked to the corresponding site. Per Google, these are the user data categories that Site Isolation can now safeguard from malicious code:Protecting CSRF defenses. This requires extra work to handle the case where only certain sites are isolated. Bringing these protections to Chrome for Android. The optimum scenario will be when each site runs in its own process and they can access only their own data.This is not yet possible in Chrome because of Chrome's current architecture - but this will change in the future.Here are Google's future plans for Site Isolation: Cross-origin messaging: Chrome's browser process can verify the source origin of postMessage and BroadcastChannel messages, preventing the renderer process from lying about who sent the message.But Site Isolation still has a lot of room to expand before actual "site isolation" is achieved, at all levels of the Chrome codebase. Wine windows 10 emulator macWe have already worked with extension authors to bring the affected Chrome user population down from 14% to 2%, as well as harden other extension security issues. For example, a small set of extensions still have broader cross-site access from content scripts, until they update to the new security model. We are working to remove cases where these protections may not yet apply. We are investigating how to protect additional data types by default with Cross-Origin Read Blocking. Protecting more types of data.
