Internet security analysts have spotted a spike in backdoor infections on WordPress websites hosted on GoDaddy's Managed WordPress service, all featuring an identical backdoor payload.

The case affects internet service resellers such as MediaTemple, tsoHost, 123Reg, Domain Factory, Heart Internet, and Host Europe Managed WordPress.

The discovery comes from Wordfence, whose team first observed the malicious activity on March 11, 2022, with 298 websites infected by the backdoor within 24 hours, 281 of which were hosted on GoDaddy.
The intrusion vector hasn't been determined, so while this looks suspiciously close to a supply chain attack, it hasn't been confirmed.

Bleeping Computer has contacted GoDaddy to find out more about this possibility, but we have not heard back yet.

Notably, GoDaddy disclosed a data breach in November 2021 that affected 1.2 million customers and multiple Managed WordPress service resellers, including the six mentioned in the introduction.

That breach involved unauthorized access to the system that provisions the company's Managed WordPress sites. As such, it's not far-fetched to suggest that the two occurrences might be linked.

In any case, if your website is hosted on GoDaddy's Managed WordPress platform, make sure to scan your wp-config.php file to locate potential backdoor injections.
