It’s too early to make any assumptions about what this means for malware in 2022, though. (Malware creators sometimes upload early builds of their malware to VirusTotal, to see if any antivirus engines detect them, which can lead to discovery of those pre-release programs by researchers.) #Free download malwarebytes for mac for mac#This may have been a proof-of-concept for Mac that hadn’t actually been released yet. However, there are some questions about whether this is actually in the wild – questions that are borne out by the lack of any detections at all in the wild. Discovered by Intezer during an investigation into a Linux server infection, this was the official first Mac malware of 2022. SysJoker coverage appeared a couple weeks before. Mac malware gets an early start in 2022ĭazzleSpy is actually not the first new Mac malware to appear so far this year, despite the fact that it’s only January. The pattern of usage, though, makes it extremely likely. In the case of DazzleSpy, the presence of Chinese strings in the executable are far from incontrovertible evidence of Chinese government involvement. Tibet (aka MaControl), discovered in March 2012, and Sabpab, discovered in April 2012, were both used to target Tibetan activists, at a time when Tibetan protests of Chinese government oppression were at a peak. To cite one example, a very similar case occurred in early 2012, in which two different pieces of malware were discovered using Java vulnerabilities to infect Macs. However, there’s a long history of suspected Chinese government use of malware to track oppressed groups, spanning many years. For example, threat actors have been known to insert Chinese- or Russian-language strings into executables in an attempt at misdirection. Can we blame the Chinese government?Īttribution is hard, and it’s very difficult to say where a particular malware sample originated without a lot of corroborating data. Then again, perhaps the similarities in usage don’t actually indicate anything at all. #Free download malwarebytes for mac code#Perhaps it’s part of a plan to change the code periodically as a means of avoiding detection. Perhaps both were run concurrently to see which performed better. Perhaps there was some dissatisfaction with the CDDS code, so new malware was written. Why there would be a need for two different pieces of malware is unclear. The most likely scenario is that this is Chinese government malware, being used for the purpose of tracking democracy advocates. However, since both were distributed through the same two macOS vulnerabilities, through pro-democracy websites in China, it’s highly likely these are made by the same folks. Thus, there’s little doubt that these are distinctly different malware, written from different code bases. #Free download malwarebytes for mac install#CDDS, for example, distributes multiple executable files across a couple different folders, while the DazzleSpy payload is a single, smaller file (which may optionally also install the open-source KeySteal exploit on older systems, in order to steal keychain data). They’re also very different in terms of what gets installed. The code is very different, and the capabilities are different. These two pieces of malware are quite different. Although the DazzleSpy implant doesn’t directly support taking screenshots, for example, that’s not hard to do via the screencapture command in the shell. #Free download malwarebytes for mac full#The full list of capabilities is a bit different than what Google described for CDDS, but it’s important to keep in mind that arbitrary shell command execution is an extremely powerful capability. That payload is a very full-featured backdoor, providing the attacker the capability to run any arbitrary command on the infected Mac, start a remote screen viewing session, download files from the Mac, steal the keychain, send synthetic mouse clicks, etc. With this high level of privileges, the malware drops its payload onto the machine. This led to the in-memory execution of native Mac code, which exploits CVE-2021-30869 to gain root privileges. The new malware got a foothold via CVE-2021-1789, exploited via a JavaScript file named mac.js loaded by the malicious site. Now, if this sounds familiar, it’s because you’ve been paying attention-this is exactly the same technique as that used by the CDDS (aka Macma) malware that was described by Google in November, even down to spreading through Chinese pro-democracy sites. It infected machines using a combination of two vulnerabilities, one in WebKit (the framework that powers Safari) and one in macOS (a privilege escalation vulnerability). DazzleSpy, a piece of malware that attacks macOS, was discovered last fall by researchers at ESET, and now those researchers have released more detailed findings.ĭazzleSpy, according to the researchers at ESET, was being spread via watering hole attacks via pro-democracy websites in China.
