Check Point experts 討論過 a new cross-platform malware XLoader, 一個 “訂閱” to which costs only $49 on the darknet. XLoader provides the opportunity to collect credentials, can act as a keylogger and runs malicious files.

XLoader originated from the well-known Formbook malware family, which mainly attacked Windows users, but disappeared from the market in 2018. 在 2020, Formbook was renamed XLoader.

新的 XLoader 惡意軟件

XLoader was first spotted last February and has gained popularity by promoting it as a cross-platform (Windows and macOS) botnet with no dependencies. The connection between the two malwares was established after it was discovered that the new malware uses the same executable file as the Formbook earlier. Then the malware vendor explained that the Formbook developer had really contributed a lot to the creation of XLoader. Because of this, malware has very similar functionality (stealing credentials, taking screenshots, 鍵盤記錄, and executing malicious files).

Looking at XLoader activity over the past six months, Check Point analysts found that it now targets not only Windows users, but macOS users as well. You can “rent” the version for macOS for $49 a month, having access to a server provided by the seller. By maintaining a centralized management infrastructure, malware authors can control how their clients use XLoader.

The Windows version is more expensive, as for it the the seller asks for $59 per month, 要么 $129 for three months.

正如剛才提到的, researchers tracked Xloader activity from December 1, 2020 to June 1, 2021, and during this time they recorded requests to buy XLoader from hackers from 69 countries. 此外, more than half (53%) of malware victims live in the United States.

XLoader is much more sophisticated than its predecessors, and it supports various operating systems, in particular macOS. Historically, macOS threats have not been widespread: they were generally spyware and did not cause too much damage. I think there is a common misconception among macOS users that Apple is more secure than others. 之前, we could say that there was a gap between malware for Windows and macOS, but now it is gradually narrowing. Malware for macOS is becoming more and more dangerous and widespread. Our recent research confirms this trend. Cybercriminals are increasingly interested in the macOS platform – and personally, I expect to see more cyber threats very soon. The Formbook family is just the beginning. 所以, I would think twice before opening attachments from emails that I receive from unknown senders.Yaniv Balmas, Head of Cyber Research at Check Point Software, 說.

讓我提醒你，我也寫過研究人員發現了針對 Windows Server 容器和 Kubernetes 集群的 Siloscape 惡意軟件.
