1000 spam mails verzonden

Zou iemand mij hier kunnen helpen met het volgend?
Ik heb wachtwoorden veranderd, virus scan gedaan maar hij blijft spam versturen.

Warning: 1000 emails have just been sent by april3ddes


The april3ddes account has just finished sending 1000 emails.
There could be a spammer, the account could be compromised, or just sending more emails than usual.

After some processing of the /etc/virtual/usage/april3ddes.bytes file, it was found that the highest sender was jenna_young@april3ddesign.nl, at 30 emails.

The top authenticated user was april3ddes, at 1001 emails.
This accounts for 100% of the emails. The higher the value, the more likely this is the source of the emails.
An authenticated username is the user and password value used at smtp time to authenticate with exim for delivery.


The most common path that the messages were sent from is /home/april3ddes/domains/april3ddesign.nl/public_html/administrator/components/com_joomlaupdate, at 1001 emails (100%).
The path value may only be of use if it's pointing to that of a User's home directory.
If the path is a system path, it likely means the email was sent through smtp rather than using a script.

The top sending script was /home/april3ddes/domains/april3ddesign.nl/public_html/administrator/components/com_joomlaupdate/ajax.php(1968) : eval()'d code:775, at 1021 emails, (102%).
Because the bulk of the emails have been sent by the script, please check it to confirm it has not been compromised.

Edit Jelle: Ik heb de melding tussen tags geplaatst, volgende keer graag zelf even doen.

Hallo,

Namens het Joomla!NL team heet ik je van harte welkom op dit forum.

Meestal wordt een site gehackt doordat er Malware of Spyware op je lokale pc zit.
Ga dus als volgt te werk:

1. Zorg ervoor dat je PC Spy- en Malware vrij is.
2. Zet een goede recente backup terug.
3. wijzig al je wachtwoorden.
4. update je site naar de nieuwste versie van Joomla en vergeet ook niet alle extensies mee te nemen.
5. Maak meteen een nieuwe backup.
