At the time of their elimination, they were mounted on tens of hundreds of WordPress websites.
According to an evaluation by researchers from internet site protection company Wordfence all the plug-ins have been purchased during the last six months via the equal actor with the express goal of backdooring them.

Until browser vendors address this problem somehow, it’s probably excellent for users to keep away from the use of the integrated password managers and disable the autofill alternative in 1/3-birthday party solutions.
