Clipboard: read-only files support
This Google Chrome brings a very useful feature for webmail users as they can now copy and paste a file into an email message to have it automatically be attached.
“Chrome supports files via DataTransfer for drag and drop, but not for clipboard,” explains Google’s status page for this feature.
“It is useful for users to be able to use clipboard keyboard shortcuts such as Ctrl+C, Ctrl+V for a task such as attaching a file to an email rather than only drag and drop.”
Continued NAT Slipstreaming protection
Chrome 91 includes additional protection from NAT Slipstreaming attacks by blocking port 10080, which Firefox has already blocked since November 2020.
NAT Slipstreaming attacks abuse a router’s Application Level Gateway (ALG) feature to gain access to any port on an internal network, potentially allowing threat actors to gain access to services that are normally secured by the router.
When determining if the port should be blocked, developers found that Amanda backup software and VMWare vCenter utilize the port but would not be affected by the block.
