As both Macs and Mac malware increase in prevalence, the importance of testing the software intended to supplement the internal security of OS X increases too. But testing security products on Mac is tricky, due to Apple’s own countermeasures. Can it be made easier?
Protection and remediation tips for Mac OS X users targeted by a Trojan adware plugin called Yontoo hidden behind movie trailer and other media playing links, generating money for criminals exploiting online ad schemes.
Does your Apple Mac need antivirus software, or any other kind of security software? This question has been asked repeatedly over the years and I think the “correct’ answer has changed over time.
If you recently acquired an Apple Mac computer there are several simple steps you can take to protect your new machine, and all of the valuable information you will be storing on it.
Does the expression 'In the Wild' still mean anything today? Well yes, in the sense of something that is 'out there' threatening real-world systems. But things move a lot faster these days than they did in the 90s and later, fastburning mass-mailers notwithstanding. Just a few days ago (on the 30th of November, to be
Six months ago, Flashback was attracting a lot of attention from researchers and media due to its wide spread and interesting features. Since then, we have witnessed its operator abandoning control of the botnet by shutting down its latest command and control server. This happened in May this year. The number of infected systems has
The Flashback trojan has been all over the news lately, but it is not the only Mac malware threat out there at the moment. A few weeks ago, we published a technical analysis of OSX/Lamadai.A, the Mac OS X payload of a multi-platform attack exploiting the Java vulnerability CVE-2011-3544 to infect its victims. OSX/Lamadai.A has
The biggest Mac botnet ever encountered, the OSX/Flashback botnet, is being hit hard. On April 12th, Apple released a third Java update since the Flashback malicious code outbreak. This update includes a new tool called MRT (Malware Removal Tool) which allows Apple to quickly push malware removal code to their user base. The first mission
If you are a Mac user and you have Java installed on your Mac, then right now would be a good time to run Software Update… from the Apple menu to make sure you have installed the latest Java for Mac OS X update. Installing this update will help protect your Mac from a malicious
Earlier this month, researchers from AlienVault and Intego reported a new malware attack targeting Tibetan NGOs (Non-Governmental Organizations). The attack consisted of luring the victim into visiting a malicious website, which then would drop a malicious payload on the target’s computer using Java vulnerability CVE-2011-3544 and execute it. The webserver would serve a platform-specific JAR
Yesterday, ESET announced the discovery of a new threat against the Apple Mac OS X platform. Today, we have found a new version of the same threat. The new version is similar to the previous version with two important differences. The first addition to this threat is that it now implements persistence on an infected
We’ve just come across an IRC controlled backdoor that enables the infected machine to become a bot for Distributed Denial of Service attacks. The interesting part about it is that it’s a Mach-O binary – targeting Mac OS X. ESET’s research team compared this to samples in our malware collection and discovered that this code
Forensic software developer PassWare announced a new version of its eponymous software forensics kit on Tuesday. Already several news sources are writing about how the program can automatically obtain the login password from a locked or sleeping Mac simply by plugging in a USB flash drive containing their software and connecting it to another computer
The MacDefender malware has morphed again, now taking the guise of "MacShield." As in the case of its oldest sibling MacDefender, the MacShield variant has taken the name of a legitimate Mac OSX software product with small distribution, doubtless causing the real developer significant heartache. The UI is essentially unchanged, but as usual all
In the last few days, I have been asked by a journalist (or four) what MacDefender means for the future of Apple security, and if I thought there was excess hype around it. I'll address the second question first. I think its safe to say the current malware would not be newsworthy if
The recent MacDefender Trojan has been receiving “rebranding” facelifts since it came out. It has now been deployed as MacProtector, MacDetector, MacSecurity, Apple Security Center, and there are no doubt more iterations to come. The malware has been updated, and now sports an improved UI that looks like a native Mac OSX application, unlike the
You may have seen some headlines today about a New Java Trojan that attacks Macs. It turns out that it also attacks Windows and Linux users as well. The Trojan pretends to be a video on Facebook. A user gets a message asking “is this you in this video” with a link. Upon clicking the
[C. Nicholas Burnett, the manager for ESET LLC's tier three technical support, contributed the following guest blog article on the FireSheep plugin for Firefox. Thank you very much, Carl! Aryeh Goretsky] The past several days have seen the security community abuzz about a program presented in San Diego at ToorCon 12 this last weekend called
