If you have an accountDropboxor pCloud, be careful. ESET's cybersecurity research lab has identified new malware that uses online storage services and a backdoor to siphon data from your Mac. Yandex Disk, another competing platform, is also affected.
At the moment, it is difficult to know how many machines have been infected in this way, but it seems that the malicious program is relatively recent. He actually made his first victim on February 4, which still potentially gave him time to corrupt thousands of computers. For now,Appledid not react directly, perhaps because the exact process used by the pirates to achieve their ends remains unclear.
Your documents in danger
According to ESET analysts, the CloudMensis virus is capable of executingthirty-nine different orderswithout the consent of the Mac owner, remotely and discreetly. Among its capabilities is the ability to download files from your memory, including screenshots and even emails. A real risk for companies therefore, especially if their equipment is notprotected by a good antivirus.
Fortunately, the attacks aretargetedand therefore only concern a minority of Internet users. The experts who discovered the malware do not give precise instructions on how to protect against it, which suggests that you will have to wait for an update from the developers to be fully protected.
Change with macOS Ventura
At the last Worldwide Developer Conference held in California in June, Apple presentedle mode Lockdownwhich aims to combat this type of incident. Also available on iPhone and iPad, this tool limits access to features often favored by hackers to spy on you. Among other things, this involves blocking attachments in messages or deactivating FaceTime calls with unknown numbers.
Lockdown mode could therefore prove very useful in the case of CloudMensis. But we will have to waitthis fallto be able to test macOS Ventura in final version, the operating system being only accessible in beta for the moment.
