No More JavaScript Attachments for Gmail Users

February 21, 2017

Malware infections typically come from hyperlinks in an e-mail message that download the bad stuff. Attachments with a malicious payloads is another popular delivery method. By now you should know not to click on suspicious links or open attachments such as .exe or .bat files that could execute code. Google is once again trying to protect users from themselves. Gmail now blocks any JavaScript (.js) attachments. Gmail users will no longer be able to receive or send a .js file attachment. For the life of me, I can't see why you would need to send a JavaScript attachment, but apparently it's a big enough problem that Google is taking action. You may be trying to open a JavaScript attachment because your system is configured to hide the file extension of known file types. My machines are configured to show the file extension for all files – yours should be too.
