VirusTotal aggregates many antivirus products and online scan engines to check for viruses that the users own antivirus may have missed, or to verify against any false positives. Several antivirus companies, including Sophos, F-Secure and Intego, offer security software for the Mac. Mac users had their biggest malware scare earlier this year, when a series of fake security programs, dubbed "scareware," were aimed at them. In this new thread, the malware will enumerate the running processes (T1057 Process Discovery) and services (T1489 Service Stop) and check if the name matches with a list of 41 processes (Appendix A Terminated Processes) and 64 services (Appendix B Terminated Services) the malware has hardcoded in the sample. Checks of several Computerworld Macs running Lion, for instance, found that Apple last updated its detector on Aug. like unknown file type on your Windows machine or, if youre a Mac user.

Mac malware is typically crude in comparison with what targets Windows PCs.īecause the C&C server is not yet operational and since it found samples of the Trojans on VirusTotal - a free service that runs malware against a host of antivirus engines - F-Secure speculated that the malware is still in the testing phase.Īlthough Apple's Mac OS X includes a bare-bones antivirus detector, it has not been updated to detect the just-noticed Trojan dropper or backdoor. We take a look at what it is, how to recover from an attack, and how to. F-Secure said that the PDF was another sleight-of-hand trick: " drops a PDF file in the /tmp folder, then opens it to distract the user from noticing any other activity occurring," the company said in a description of the attack.īoth Sophos and F-Secure noted that the malware doesn't work reliably, and currently can't connect to the command-and-control (C&C) server because the latter isn't fully functional. Once run, the dropper downloads the second-stage backdoor and opens a Chinese-language PDF. The Mac malware uses a two-step process, composed of a Trojan "dropper" utility that downloads a second element, a Trojan "backdoor" that then connects to a remote server controlled by the attacker, using that communications channel to send information gleaned from the infected Mac and receiving additional instructions from the hacker.īecause it doesn't exploit a vulnerability in Mac OS X - or any other software - the malware instead must dupe users into downloading and opening the seemingly-innocuous PDF document, which is actually an executable. That practice relies on what is called the "double extension" trick: adding the characters ".pdf" to the filename to disguise an executable file.
