With the latest Lion security update, Mac OS X 10.7.3, Apple has accidentally turned on a debug log file outside of the encrypted area hat stores the user’s password in clear text!
===> Anyone who used FileVault encryption on their Mac prior to Lion, upgraded to Lion, but kept the folders encrypted using the legacy version of FileVault is vulnerable. FileVault 2 (whole disk encryption) is unaffected. <===

Microsoft explique avoir analysé le comportement d'un malware ciblant une faille au sein de Microsoft Office pour Mac.
===> « Aucun système d'exploitation sortant des laboratoires est immunisé contre les malwares », conclut ainsi Microsoft même si la vulnérabilité en question se trouve tout de même au sein d'une suite de logiciels développés par ses propres soins. <===
Quoi qu'il en soit, l'éditeur conseille aux utilisateurs de Microsoft Office pour Mac 2004/2008 d'activer les mises à jour. Notons que Mac OS X Lion n'est pas concerné par ce malware.

Oxford Muses on Mac Flashback: Worst Outbreak Since Blaster
So how bad was last month's Mac Flashback outbreak and who suffered the most? Our guess: it was bad, and university IT help desks.
And it looks like our guess might not be far off the mark.
===> Oxford University Computing Services' network security team (aka OxCERT) has written that they dealt "with what is probably the biggest outbreak since Blaster struck the Windows world all the way back in the summer of 2003." <===
OxCERT dealt with around 1000 incidents for Blaster. They've seen several hundred Flashback incidents… "and they keep on coming."

Vous croyez toujours que votre Mac est sécurisé, car les PC Microsoft tombent sous les virus et les vers, mais pas les Macs ? Réveillez-vous ! Cette année a connu la première compromission majeure de Macs à travers le monde (*). Qu'en est-il du vôtre ?
Ainsi, utilisateurs de Mac, sachez que, d'une part mettre à jour en temps opportun, et d'autre part utiliser un logiciel anti-virus sont également bons pour votre Mac (et vos nerfs).
Gardez votre système d'exploitation à jour en utilisant le mécanisme de "Mise à jour de logiciels..." qui est accessible dans le menu "Apple". Utilisez les droits "administrateur" uniquement lorsque c'est nécessaire, sinon, conservez les droits "utilisateur" restreints.
Mais notez aussi qu'Apple peut encore s'améliorer: il leur a fallu des mois pour publier le correctif approprié - ce qui est long comparé au cycle mensuel de mise à jour de Microsoft.

Dr. Web's count of Macs actively infected with Flashback over time. The "A" marks Apple's release of its Flashback removal tool, and the "B" marks Dr. Web's discovery of another variant of Flashback that led to an increase in its infection count.
===> Flashback has been used for click fraud, as detailed by Symantec’s researchers. The malware redirected traffic from Google search ads to its own pay-per-click ads, generating as much as $10,000 a day. <===
Even with its command and control servers disabled, the infected machines continue to engage in that traffic-hijacking. And with nearly half a million users still infected, Flashback’s authors are still likely profiting from their scheme.

The same Java vulnerability used in the infamous Flashback malware is now being used as an attack vector for a single piece of malware that can infect both Windows and Mac OS X computers.
Security vendors have discovered a new piece of malware that attacks both PCs and Macs. It uses the same Java security vulnerability exploited by the Flashback malware that infected hundreds of thousands of Macs. While the attack vector is the same as in Flashback, this Java Applet checks which OS it is running on and downloads suitable malware for it.

A l’occasion de l’analyse d’un programme malveillant sur Mac OS X, exploitant une ancienne faille d’Office, Microsoft glisse une conclusion sur la sécurité du système d’Apple.
Une analyse qui se croise avec les critiques de Kaspersky sur la sécurité d’Apple, mise en doute suite à la diffusion du cheval de Troie Flashback.
Sur le Malware Protection Center, Microsoft est revenu le 30 avril sur un programme malveillant actif sur l’environnement d’Apple et qui exploite une faille d’Office pour Mac vieille de trois ans.
A noter que cette faille n’est exploitable que sur les versions Snow Leopard et précédentes de l’OS, Lion n’étant donc pas concerné.
Restez sur vos gardes, cela promet... rien de bon...

Jahrelang hat Apple Java für sein Mac OS selbst bereit gestellt und im Grunde versucht es loszuwerden.
Doch jetzt hat man sich mit Oracle geeinigt, dass der Java-Hersteller diese Aufgabe übernehmen soll. Mac-Benutzer sollen in Bezug auf Java also Windows- und Linux-Nutzern gleichgestellt und somit früher als bislang mit Sicherheits-Updates versorgt werden.

Apple may have appeared to have pulled off a coup in persuading Oracle to maintain Java for Mac but can Oracle be trusted to get it right?
The emergence of the Flashback Trojan - which exploited a vulnerability in Mac OS X's version of Java - earlier this year led to a lot of flak for both Oracle and Apple. The vulnerability was known about and fixed in the Windows and Linux versions of Java, but remained exposed in OS X for several more weeks.
===> The fact that Apple is ultimately responsible for maintaining Java on OS X saw Apple's ability to protect its users questioned. <===

With the recent glut of high profile Mac-based malware like MacDefender and Flashback, it’s easy to forget that Macintosh computers (and Mac malware) have been kicking around for more than thirty years – longer, even, than Windows malware.
In fact, the first documented Mac virus actually predated some of the first PC viruses by a good four years. While conventional wisdom has always assumed that Macs are inherently safer than PCs, wider adoption of Macs in recent years has given rise to new and more sophisticated threats, with many suggesting that Apple’s honeymoon with malware authors may be over.
As this slideshow of Mac Malware through the years shows, however, Apple machines are no strangers to malicious software.
