Someone calling themselves "Pro_Mast3r" managed to deface a server associated with President Donald Trump's presidential campaign fundraising on Sunday, The server, secure2.donaldjtrump.com, is behind Cloudflare's content management and security platform, and does not appear to be directly linked from the Trump Pence campaign's home page. But it does appear to be an actual Trump campaign server—its certificate is legitimate, but a reference to an image on another site is insecure, prompting a warning on Chrome and Firefox that the connection is not secure.

The page, now displaying an image of a man in a fedora, displays the following text:

Hacked By Pro_Mast3r ~

Attacker Gov

Nothing Is Impossible

Peace From Iraq

The source code contains a link to javascript on a now-nonexistent Google Code account, masterendi, previously associated with the hacking of at least three other websites. As Italian IT journalist Paolo Attivissimo pointed out, an archive of the script shows it to be a snow animation script, not malware.

Ars reached out to both Cloudflare and the Trump-Pence campaign team for comment. As more information becomes available, we'll update this report.

[Update 4:00 pm Eastern Time] The server is now offline.
