Apple has released Security Update 2015-003 for OS X Yosemite v10.10.2 to address multiple vulnerabilities. Exploitation of one of these vulnerabilities may allow a remote attacker to take control of an affected system.

US-CERT encourages users and administrators to review Apple Security Update 2015-003 and apply the necessary updates.

FREAK heißt die Abkürzung für eine Sicherheitslücke, die Millionen Android- und iOS-Nutzer gefährdet. Weil in den Browsern von Android und iOS seit vielen Jahren eine ernste Schwachstelle steckt, die das Mitlesen der Daten auch bei verschlüsselten HTTPS-Verbindungen ermöglicht. So prüfen Sie, ob Sie betroffen sind.

IT-Forscher haben eine Sicherheitslücke entdeckt, die SSL-Verbindungen unter Android, iOS und Mac OS X gefährdet. Der sogenannte Freak-Fehler soll mehr als 14 Millionen Webseiten betreffen.

Auf die SSL-Sicherheitslücken Heartbleed undPoodle folgt nun Freak: Sicherheitsexperten der französischen Forschungsanstalt INRIA und des mitLS-Teams haben eine schwere Sicherheitslücke entdeckt, die vermeintlich sichere SSL-Verbindungen unter Android, iOS und Mac OS X aushebeln soll. Der Fehler trägt den Namen Freak (Factoring Attack on RSA-Export Keys) und betrifft laut einer Untersuchung der Universität Michigan derzeit mehr als 14 Millionen per HTTPS ausgelieferte Webseiten - darunter befinden sich neben US-amerikanischen Behördenseiten wie Whitehouse.gov, NSA.gov und FBI.gov auch Webseiten, die hierzulande populär sind wie Deichmann.com, Porsche.com oder Giga.de. Auf der Webseite FreakAttack sind alle betroffenen Seiten aufgeführt, zudem finden Nutzer hier einen integrierten Browser-Test.

Every vulnerability found may be good news ("it's been found!"), but it's also a failure of quality control and testing.

Are you surprised to see OS X and iOS top the chart?

Im Jahr 2014 blockierten die Lösungen von Kaspersky Lab insgesamt 3.693.936 Infektionsversuche unter Mac OS X.

Die Experten von Kaspersky Lab entdeckten 1.499 neue Schadprogramme für Mac OS X, das sind 200 Schädlinge weniger als im entsprechenden Vorjahreszeitraum.

===> Jeder zweite Anwender von Apple-Produkten war einem Angriff ausgesetzt. <===

Im Laufe des Jahres war jeder Mac-OS-X-User durchschnittlich neunmal mit einer Cyberbedrohung für sein Betriebssystem konfrontiert.

Is there any (Mac) OS X-specific malware around? Oh yes. But for some odd reason I haven't said anything interesting on this topic for quite a while… The last time was two and a half years ago. Yes...

So what can we deduce from these data?

First: cybercriminals find it easiest making money with mostly legal (well, almost legal) approaches. Persistent advertising also makes money, and coupled with large-scale infections – big money.

Second: OS X virus writers are a fairly rare but sophisticated species. Unlike the Windows virus scene, the OS X virus scene bypassed the childish stage of ‘viruses for fun’ and went straight to the grown-up – Mac OS – stuff with all the attendant hardcore malware tricks that are necessary for it. These are serious folks, folks! It’s very likely they honed their skills on the Windows platform first, and then went over to Mac to conquer new, uncharted territory in search of new untapped money-making possibilities. After all, the money’s there, and the users are relatively blasé about security, which means there are plenty of opportunities – for those blackhatters who are willing to put in the work.

Third: professional espionage groups have really taken to exploiting OS X. Many APT attacks in the last few years acquired Mac-modules, for example Careto, Icefog, and the targeted attacks against Uyghur activists. Yes, here we’re talking pinpointed –exclusive as opposed to mass – attacks, aimed at specially chosen victims; this is why they don’t figure in the top-20. Not that they are any less dangerous; especially if your data may be interesting to intelligence agencies.

The patch comes hours after the leaked photos emerged.

Sometimes I wish the internet could just be a place to exchange wholesome information, such as cooking recipes and tips on Linux, but sadly, there is a dark side. There are deviant people lurking on the web doing all sorts of horrible things. Yesterday, a hacker leaked the private pictures and videos (nude and semi-nude) of many celebrities, and they have spread across the net. For these celebrities, who are real people, I am sure it has been a very trying time; their privacy has been destroyed and I offer my sympathies. For the many people (if they can be called that) viewing and spreading the pictures, the occasion has been dubbed

During his talk at HOPE/X Jonathan Zdziarski detailed several undocumented services (with names like 'lockdownd,' 'pcapd,' 'mobile.file_relay,' and 'house_arrest') that run in the background on over 600 million iOS devices.

Zdziarski's questions for Apple include:

• Why is there a packet sniffer running on 600 million personal iOS devices instead of moved to the developer mount?
• Why are there undocumented services that bypass user backup encryption that dump mass amounts of personal data from the phone?
• Why is most of my user data still not encrypted with the PIN or passphrase, enabling the invasion of my personal privacy by YOU?
• Why is there still no mechanism to review the devices my iPhone is paired with, so I can delete ones that don’t belong?

... and his last slide (page 57 of the PDF) sums it up nicely: 

• Apple is dishing out a lot of data behind our backs
• It’s a violation of the customer’s trust and privacy to bypass backup encryption
• There is no valid excuse to leak personal data or allow packet sniffing without the user’s knowledge and permission.
• Much of this data simply should never come off the phone, even during a backup.
• Apple has added many conveniences for enterprises that make tasty attack points for .gov and criminals
• Overall, the otherwise great security of iOS has been compromised… by Apple… by design.

Apple a définitivement abandonné la sécurité de son Mac OS X 10.6, pourtant encore largement utilisé.

Targeted attacks aim to steal sensitive data from Mac systems, says F-Secure
