nwn/emule critical application hijacking

[Ganondolf]

Salve a tutti.
Poco fa, mentre provavo ad lanciare un videogame, mi è spuntata una preoccupante finestrella di Sygate Personal Firewall che mi ha avvisato che nwn.exe (l'eseguibile del gioco) stava cercando di lanciare emule (o.o'). Ho rifiutato la richiesta e sygate ha loggato un application hijacking di gravità "critical".

Application Hijacking has been detected
The application: C:\Programmi\NeverwinterNights\NWN_ITA\nwn.exe try to launch another application: C:\Programmi\eMule\emule.exe to go to remote host 99.255.192.218

il BackTrace mi ha mostrato un elenco di 19 indirizzi IP, di cui l'ultimo è quello menzionato sopra. Queste le informazioni riportate sull'IP:

ho eseguito una scansione delle cartelle dei due programmi con AVG ma non ha trovato nulla.

Fatto questo, ho disconnesso il modem e ho lanciato hijackthis. log:

Poi ho dato una ripulita con ccleaner, ho riavviato, e ora sto postando.
Qualcuno può aiutarmi a capire cos'è successo?

[ste_95]

Oddio, non che eMule sia un sito infetto, e francamente, se utilizzi un buon antivirus, io lo lascerei passare per vedere cosa succede. Negando, riesci a giocare?

[clic]

sembrerebbe a prima vista che un malware non meglio identificato tenti di lanciare emule per qualche suo scopo (application hijacking). Questo non significa che emule sia infetto, è un progetto open e se lo hai scaricato dal sito ufficiale non è lui la causa.

Sappiamo bene che i virus writers progettano le loro creature a stadi (tipo i vettori spaziali) onde poter minimizzare la possibilità di essere individuati e per poter aggiornare frequentemente alcune parti che vengono poi autonomamente riscaricate una volta che la macchina è infetta: ci sarebbe quindi da capire se si tratta di una tecnica (interessante e che non conoscevo) per distribuire codice malevolo attraverso il circuito p2p piuttosto che usare server i cui indirizzi potrebbero essere bloccati e quindi non più raggiungibili dai precursori delle infezioni vere e proprie (downloader e dropper vari).

Si, ho chiuso e da allora parte tranquillamente. Neanche emule ha dato altri problemi.
che dire... boh
