Critical security problem in UpdraftCentral: an attacker holding the service’s keys planted a backdoor on our websites

October 19, 2026

On the night of 19 October 2026 an attacker abused UpdraftCentral, the remote management service built into UpdraftPlus, a backup plugin with more than 4 million installations, and planted a backdoor on two of our three websites.

We publish an analysis of the backdoor, indicators of compromise and a way to check your own sites. The vendor later confirmed that the attacker obtained the teamupdraft.com customer database, including UpdraftCentral keys.
