Developers will, however, receive a console error, the paper explains.Note: If you have no idea whether an installed program is “good” or not, err on the side of keeping it, lest you accidentally remove something rather critical to Windows’ healthy operation). The implementation will be made without any visible change, and the downloads would just fail silently. Thus, we plan to prevent downloads in sandboxed iframes that lack a user gesture, and this restriction could be lifted via an ‘allow-downloads-without-user-activation’ keyword, if present in the sandbox attribute list,” he says. “Content providers should be able to restrict whether drive-by-downloads can be initiated for content in iframes.

That's what I wanted You can do this by editing the extension's manifest.json file: On Windows: C:\Users\Then, even if you click a sandboxed iFrame, the token must contain the “allow-downloads-without-user-activation” keyword. The downloads will just fail silently without any warning to usersįirst of all, the download must be triggered by the user, so unless you click on a download link, no file should be offered to you. Google believes it can resolve this issue by making it harder for unintended downloads to show up, enhancing its filters to block such actions unless they meet three different conditions.
In most of the cases, they are used by malicious actors by embedding them into website iFrames, thus being able to hide malware or other dangerous payloads inside the content of pages looking legitimately. Technically, the concept of drive-by-downloads refers to downloads that are generated without users specifically requesting them. The application, which according to third-party data runs on more than 65 percent of desktop computers, will be updated with a security feature to block drive-by-downloads. Google Chrome browser will soon get new capabilities that will help block unintended downloads.
