sites cleaned in a single coordinated pass

1

evening session, 16 October 2026

1

login with the owner’s password identified as the probable way in

The problem

A self-healing loader kept reinstalling itself across every WordPress site on the account, from files, the database and server memory. A service worker planted in administrators’ browsers kept handing the attackers new logins, even after the files were clean.

What we did
01

Mapped every site on the account instead of cleaning one in isolation

02

Contained all eleven sites at the same moment, then removed the loader and every copy of it in one evening session

03

Removed the service worker from administrators’ browsers before any new password was typed

04

Traced the entry to a login with the owner’s own password (rated probable, not proven) and changed every password

Before

Eleven sites reinfected within hours of every hand clean-up, hidden administrators on each.

After

All eleven cleaned and verified together; hidden administrators and the browser service worker removed.
