JavaScript Shield

+

+ JavaScript Shield modifies the behaviour of the JavaScript environment availble for the visited + webpage. JShelter provides fake information to confuse fingerprinters or make webpage triggered + attacks impossible or harder. +

+

+ JavaScript Shield internally consists of wrappers, small pieces of code that modify the + original behaviour of a JavaScript API (a function or a property) defined by standards. The + behaviour of the most of the wrappers can be divided into several categories: +

+
    +

  • + Precision reduction: The original value is too precise and it is not necessary for most use + cases. JavaScript Shield modifies the values so that typical and benign use cases are not + affected. +

    • +

  • + Provide fake information: Some wrappers provide fake information mostly to confuse + fingerprinters. For example, canvas wrappers modifify the image so that the same instructions + produce different result in each session and for each domain. +

    • +

  • + Hide information: Some APIs provide information that is not generally needed and can be hidden + from most of the pages. Depending on the API, JavaScript Shield might return an error, an empty + value, or block the API completely. +

    • +
+

+ See our blog post for more information on browser + fingerprinting counter-measures and farbling. +

+ Network Boundary Shield prevents web pages to use the browser as a proxy between local network + and the public Internet. See our + blog post and + Force + Point report for examples of attacks handled by the Network Boundary Shield. + The protection encapsulates the WebRequest API, so it captures all outgoing requests. +

+

+ Generally, you want Network Boundary Shield to block all suspicious requests. However, some pages can be + broken, because they require interaction between public Internet and local network, for example, + some Intranet information systems might be broken by the Network Boundary Shield. JShelter users + also reported increased number of false positives when using DNS-based filtering programs. If + you use one, make sure that DNS returns 0.0.0.0 for the blocked domains. +

+

+ Network Boundary Shield default behavior can be globally adjusted by the settings below. Network Boundary Shield can also be completely + disabled on a per-domain basis using the whitelist. Domains can be whitelisted via Network Boundary Shield switch in the popup window + or manually via Manage whitelist option. Keep in mind that whitelisting a domain will also whitelist its subdomains. To selectively + deactivate the Network Boundary Shield, insert the domains to the whitelist (excluding "www", but including all other domains e.g. ".com"). +

+ Fingerprint Detector provides a mechanism that informs users about fingerprinting activity on visited web pages. The detector also prevents + web pages from extracting browser fingerprint, if a user chooses to do so. See our + blog post or + Browser Fingerprinting: A survey for a closer description of browser fingerprinting. +

+ By enabling the detector, you will be notified whenever it detects fingerprinting behavior on a visited web page. The detector measure severity of + potential fingerprint with each page visit. Then, it assigns a likelihood of fingerprinting to the page according to our heuristic system. The likelihood is + presented to you by badge color of JShelter icon and also in popup window. If a high likelihood of fingerprinting occurs, you will be notified by a separate notification. + It's possible to show details about the fingerprint by generating a fingerprint report. You can access it via popup window or by clicking directly on the notification. +

+

+ The default behavior of Fingerprint Detector can be adjusted to your liking. You can choose "blocking" behavior, which works as a countermeasure against leaking your fingerprint + to unwanted parties. In this case, every positive detection is followed by blocking all subsequent HTTP requests and cleaning browser storage. Take into account that this action + will probably result in a broken web page and we strongly recommend to use a whitelist for trusted domains. Switching off the detector for a domain in the popup window will add + the domain to the whitelist. This domain won't be evaluated or blocked in the future. You can manage all the whitelisted domains below. +
