Bonjour,
J'ai installé l'extension email-newsletter sur mon site basé sur WordPress.
Il semble que cette extension comporte une faille puisque depuis que celle-ci a été "découverte" sur mon site, mon serveur fait l'objet de requêtes HTTP incessantes.
Voici ci-dessous un exemple (réduit) de requêtes incessantes.
Vous pouvez constater que les adresses IP sont toutes différentes, ou presque, notamment depuis que j'ai supprimé les fichiers de l'extension.

D'où l'erreur 503 en réponse d'ailleurs.
La signature du navigateur serait chinoise, même si je sais que cela ne donne en réalité aucun indice sérieux sur l'identité du pirate.
Il semblerait que les adresses IP correspondent elles-mêmes à des machines de relais.
En effet, j'ai banni une bonne vingtaine d'adresses IP avant de poster sur ce forum. (commande ip ro add blackhole IP)
Quelqu'un a-t-il déjà rencontré ce phénomène ?
Merci d'avance
