[QUOTE="Andy Ful, post: 979015, member: 32260"] The problem of drive-by download without permission is usually related to HTML Smuggling. If you open a compromised or specially crafted web page (also specially crafted HTML attachment), then the embedded JavaScript can automatically do some things without your permission: [LIST=1] [*]Download a payload from a malicious URL to your disk. [*]Drop a payload already embedded in the HTML attachment. [/LIST] This can be prevented by blocking scripts in the web browser, but such a setting will also break many web pages. Look for example here: [URL unfurl="true"]https://www.microsoft.com/security/blog/2021/11/11/html-smuggling-surges-highly-evasive-loader-technique-increasingly-used-in-banking-malware-targeted-attacks/[/URL] The attacker still cannot automatically execute the payload. In theory, the payload can be downloaded and executed without your permission, but this would require exploiting the web browser. Such exploits are quickly patched, so you probably will never see any of them. Post edited. I am not sure if the setting "Ask where to save..." can effectively solve the problem. The file can be probably saved without this alert to the default location. [/QUOTE]
