![]() ![]() ![]() When another machine is booted with this worm-infected device inserted, the machine firmware loads the option ROM from the infected device, triggering the worm to initiate a process that writes its malicious code to the boot flash firmware on the machine. “The worm would then spread to any other computer to which the adapter gets connected.” The proof-of-concept malware would “be on the lookout for any peripherals connected to the computer that contain option ROM, such as an Apple Thunderbolt Ethernet adapter, and infect the firmware on those,” explained Wired. The malware could “spread automatically from MacBook to MacBook, without the need for them to be networked.” Attackers could remotely target computers, even air-gapped ones, with Thunderstrike 2 as it is designed to spread by infecting the option ROM on peripheral devices. But Kovah said that’s not true he told Wired, “It turns out almost all of the attacks we found on PCs are also applicable to Macs.” In fact, the researchers said five of the six vulnerabilities studied affect Mac firmware.Īttackers might choose to infect a target via a phishing email and malicious site. The researchers previously used LightEater when they presented “ How Many Million BIOSes Would you Like to Infect?” After they revealed that about 80% of PCs have firmware vulnerabilities, Apple claimed Macs did not. In addition, to emphasize the consequences of successful exploitation of these attack vectors, we will demonstrate the power of the dark side by showing what Mac firmware malware is capable of.” PCWORLD BEST MAC CLEANER SOFTWAREThis talk will provide conclusive evidence that Mac's are in fact vulnerable to many of the software only firmware attacks that also affect PC systems. ![]() “Interestingly, when contacted with the details of previously disclosed PC firmware attacks, Apple systematically declared themselves not vulnerable. “Although several attacks have been presented against Mac firmware, unlike their PC counterparts, all of them required physical presence to perform,” they wrote in the description of their talk. Apple previously claimed that Macs were not vulnerable to the same firmware flaws that could backdoor PCs, so researchers proved they could remotely infect Macs with a firmware worm that is so tough to detect and to get rid of that they suggested it presents a toss your Mac in the trash situation.Ĭorey Kallenberg, Xeno Kovah and Trammell Hudson will present “ Thunderstrike 2: Sith Strike” at Black Hat USA on August 6. Just click on that icon to open the stack.When companies claim their products are unhackable or invulnerable, it must be like waving a red flag in front of bulls as it practically dares security researchers to prove otherwise. Consider the Use Stacks feature to automatically stack-up files of the same type into a single icon. Right-click (two-finger tap on a trackpad) any open space and choose Clean Up to get things arranged neatly, or Clean Up By to sort them as well. If your desktop is littered with icons, you should probably tidy things up a bit. But you may have old large files and documents, or apps that no longer even work on your version of macOS, that you can safely remove. Big library files (for apps like Lightroom or Final Cut Pro) are likely to show up here, and you might not want to mess with them. There are several sections here, like Large Files and Unsupported Apps, that are worth perusing. Then, click on Documents in the left tab. You can see all your installed applications here and sort them by size, easily deleting apps you haven't used in ages. While you're in the Storage Management app, click on the Applications tab in the left column. ![]() Take a look at your Applications and Documents PCWORLD BEST MAC CLEANER TVThe Optimize Storage solution will get rid of things like old TV shows you've already watched and old email attachments when you're low on storage space. In the Recommendations tab you'll see a number of useful options, like Store in iCloud and Empty Trash Automatically.
