In that respect, at least, it is the polar opposite of the next malware to break in 2018. OSX.Dummy was so named because it took an extraordinary amount of compliance from the victim to successfully compromise a target. The tool installs a bash script which leverages python to open a reverse shell: The scammers didn’t have to try to hard, either, as they offered the malware as an answer to a problem the victims had themselves sought help for. The attackers convinced victims to knowingly run a tool with elevated privileges because they believed it was from a trusted source.

In July, OSX.Dummy made an appearance on a number of cryptomining chat groups.

Safari users are, as a matter of general safety, always wise to uncheck the following setting in the General tab of Safari’s preferences: This feature means that macOS will automatically register custom URLs defined in the malicous software, which then contribute to further infection.

The backdoor WindTape takes a screenshot of the current Desktop, sends it to a C2 server and deletes the local copy. xlsx and uses a LoginItem for persistence. WindTail.A targets files on the victim’s machine having the following extensions. Although first believed to have targetted macOS as early as January last year, WindShift appears to have picked up its activity during 2018, as this figure (courtesty of DarkMatter) shows: WindShift APTĪlthough created at the end of April, the AppleJeus campaign was not discovered until August, and that month also brought news of yet another APT group targetting the Mac platform, WindShift APT. In either case, the application had a valid developer signature and so easily bypassed Apple’s built-in security technologies. It’s unclear whether this malware, dubbed OSX.AppleJeus, was a supply chain attack or whether the CelasTradePro.app was specifically created to infect cryptocurrency exchanges. A trojan downloader inserted as an updater in the CelasTradePro.app, a LaunchDaemon with the label “” and the payload, initially dropped at /var/zdiffsec. Attributed to North Korean-linked APT group Lazarus, the malware consists of three parts. Lazarus APTĪfter two important discoveries coming right at the beginning of the year, things remained relatively quiet on the malware front until April, which saw the release of a cryptocurrency trading application named CelasTradePro. Interestingly, or perhaps worryingly, both MaMi and CrossRAT had version numbers which indicate that they are in early development, and it would be no surprise to see more advanced versions of both surface in the future. CrossRAT is a multi-platform surveillance tool that manifests itself on macOS by writing a copy of itself to ~/Library/mediamgrs.jar and installing a user LaunchAgent for persistence. In the same month, the Java-based CrossRAT was uncovered as part of the toolkit of Dark Caracel APT, a group that gathers intelligence for national security purposes and offensive cyber capabilities allegedly on behalf of the Lebanese government. The malware contains logic for downloading and uploading files remotely, recording mouseClicks, taking screenshots and attempting privilege escalation. Mami alters macOS’s ist in order to hijack the victim’s DNS servers.

The year began with OSX.MaMi, a suspected macOS variant of an older Windows malware, DNSUnlocker. Cryptojacking remains on the rise, but confined largely to the ever-present macOS adware problem. Cryptocurrencies have also been big in the malware news this year as bad actors have both targeted bitcoin wallets and made use of cryptocurrency utilities to infect unsuspecting users. EvilOSX, EvilEgg and a Java-based RAT also made appearances in the wild. As 2018 starts to wind down, we take a look at how the macOS security situation has unfolded throughout the year.Ģ018 has been very much the year of the RAT for macOS, with Empyre leading the way as the exploitation framework of choice for several malware variants.
