I really want to reiterate how this can go wrong frequently and fast, folks.
A malicious actor sets up a page with an auto-downloader squatting on a domain name that matches a common zip file name like photos DOT zip. This website is set up to start an auto downloader upon being visited, downloading a zip file with the same name as the URL which contains malicious software (virus, worm, keylogger, etc).
Someone you know well sends you an email or text with promised photos attached. The email even reads something like this.
Because .zip is now a TLD, that plain text is automatically formatted into a link to malicious actor's website without them having to send you anything.
Folk with family with iPhones or iPads that are sent multiple photos in one go might be familiar with iCloud's tendency to automatically compile them into zip file for the sender and less savvy tech users have trouble NOT doing that.
These same less savvy users, or even just someone just not thinking in the moment, will click that .zip link, not realizing it isn't the the same as clicking on the promised attachment.
They download a file that matches the name they expected. They open it because they were expecting that file and it's from a trusted source. Except the file they downloaded isn't the one that was sent by their trusted source and now they have malware.
An IT person tries to send you an email with instructions on how to resolve a problem with a commonly used filename like install-repair DOT zip or to install new software like microsoft-office DOT zip.
The email may start with instructions of where to go get the legitimate file to do the install or repair, but now a line later in the instructions is also has a link to a .zip URL. A user, already frazzled by IT problems, may click it to ensure they have the right file. Again, they download malicious code from a squatting website or it prompts them with a fake login and now the squatting website has stolen their login credentials for a legitimate site. All due to an expected email from a trusted source.
Above you can see microsoft-office DOT zip is already out there with a fake Microsoft login screen waiting to steal your credentials.
These risks are already out there now because the TLD has been activated.
Plain text on old post are already being resolved into links to the new websites.
Here you can see a tweet from 2021, long before .zip was a domain name, now resolves that plan text into a clickable link. You'll start seeing this everywhere, and malicious actors do not have to lift a finger to send it to you.
Yes, a lot of users aren't going to click that, but a lot of folk will. Whomever is squatting on photos DOT zip domain name has made a one time payment to have access to anyone that ever sees that file name typed out.
In an example of an existing squatter site, clientdocs DOT zip is exactly one such pre-setup .zip domain name that initiates an automatic download. This one may be harmless, but the set ups are already out there and waiting to catch folk.
It's an unnecessary and risky can of worms that's been opened up.
Holy Unforced Errors, Batman.
