Two new pieces of malicious software aimed at Mac computers have been discovered on the Dark Web, offered through Malware-as-a-Service (MaaS) and Ransomware-as-a-Service (RaaS) portals and estimated to have been up for around the past three weeks, beginning May 25. Originally spotted by Bleeping Computer, the two portals offer software called "MacSpy" and "MacRansom" as services for potential buyers, as well as any future support that may be needed for the malware (via Motherboard). Both portals are the work of the same malware developer, but security firms Fortinet and AlienVault described the person behind the scheme as an "inexperienced coder," pointing towards issues like the lack of digitally signed files, meaning the security measures on a standard installation of macOS would still be alerted to the malware. The researchers called MacSpy the "better-coded tool," but said MacRansom was more dangerous since it "has the potential to permanently wreck user files," if users of malicious intent ever wielded it. Thankfully, the process by which crooks would have to go about getting either MacSpy or MacRansom will likely prevent either piece of malware from spreading. Both portals are described as "closed" offerings, meaning anyone wanting to actually purchase the services off the Dark Web would have to contact the author to receive demo packages, and then directly negotiate payment. As such, "none of these two appear to be part of any active distribution campaigns." All the same, as Mac-focused security researcher Patrick Wardle told Motherboard, the increasing intent of cyber criminals to infect Apple's computers is "kind of a milestone." Security reporter Ruben Dodge said that macOS and iOS have so many "less technical people" using the software that it's simply too "ripe" of a target for criminals not to take notice. Although MacRansom and MacSpy aren't expected to take off in that way, Dodge said "it's only a matter of time" before another piece of malware or ransomware does. Malware attacks on Mac computers were up 744 percent in 2016, although that percentage was largely weighted due to adware bundling in software on MacBooks and iMacs, which is far less alarming than any potential wide-scale malware purchased by a criminal on the Dark Web. Still, Bleeping Computer pointed out in its report that Mac ransomware in particular -- which holds user data ransom until a fee is paid -- has been steadily growing over the past year. As a rule of thumb, in order to stay safe users should only download apps and programs from Apple's own Mac App Store, and if an app is available only on a third-party website the developer behind the software should be trusted. Although Apple has long advertised the Mac as a truly anti-virus and anti-malware machine, Wardle reminds Apple fans to remain vigilant online: "Mac users...should not be overconfident, and should not assume that just because they're using a Mac they're inherently safe."
