Bonsoir,
ci-après un copier-coller (en anglais) du communiqué d'Intego répercuté
sur MacBidouille.
En résumé, un virus pour Mac circule sous la forme d'un fichier avec
l'extension .mp3
Il s'exécute uniquement si on l'ouvre en double-cliquant dessus.
Faut-il y voir un lien avec une enfilade très récente sur

INTEGO SECURITY ALERT
Intego Announces Protection against the First Mac OS X Trojan Horse:
MP3Concept
Paris, France: 4:15pm, April 8, 2004 - Intego, the Macintosh security
specialist, has just released updated virus definitions for Intego
VirusBarrier to protect Mac users against the first Trojan horse that
affects Mac OS X. This Trojan horse, MP3Concept (MP3Virus.Gen),
exploits a weakness in Mac OS X where applications can appear to be
other types of files.
The Trojan horse's code is encapsulated in the ID3 tag of an MP3
(digital music) file. This code is in reality a hidden application that
can run on any Macintosh computer running Mac OS X.
Mac OS X displays the icon of the MP3 file, with an .mp3 extension,
rather than showing the file as an application, leading users to believe
that they can double-click the file to listen to it. But double clicking
the file launches the hidden code, which can damage or delete files on
computers running Mac OS X, then iTunes to play the music contained in
the file, to make users think that it is really an MP3 file . While the
first versions of this Trojan horse that Intego has isolated are benign,
this technique opens the door to more serious risks.
This Trojan horse has the potential to do any of the following:
- Delete all of a user's personal files
- Send an e-mail message containing a copy of itself to other users
- Infect other MP3, JPEG, GIF or QuickTime files
Due to the use of this technique, users can no longer safely
double-click MP3 files in Mac OS X. This same technique could be used
with JPEG and GIF files, though no such cases of infected graphic files
have yet been seen.
Intego VirusBarrier eradicates this Trojan horse, and Intego remains
diligent to ensure that VirusBarrier will also eradicate any future
viruses that may try to exploit this same technique. All Intego
VirusBarrier users should make sure that their virus definitions are up
to date by using the NetUpdate preference pane in the Mac OS X System
Preferences.
