A new kind of malware, designed for macOS computers, is making its way around the internet. It pretends to be an update for Visual Studio, a popular software used for programming, but it's actually a way for hackers to get into your computer without you knowing.
This sneaky malware, written using a programming language called Rust, can work on different kinds of Mac computers, including the ones with Intel chips and the newer ones with Apple's own chips. Experts at a cybersecurity company called Bitdefender are calling it RustDoor.
It seems like this malware might be connected to a group of hackers known for spreading other kinds of malicious software, including some that lock up your files and demand money to unlock them. Bitdefender found that the RustDoor malware talks to servers controlled by these hackers.
However, they're not completely sure if RustDoor is directly linked to those hackers or if it's just using the same servers. It's kind of like how different criminals might use the same hideout without working together.
While viruses that lock up files exist for Macs, there haven't been any big outbreaks yet. Most of these viruses target computers running Windows or Linux, which are more common in offices and big organizations.
The RustDoor malware is mostly spread by pretending to be an update for Visual Studio, a tool used by programmers. It goes by different names like 'zshrc2' or 'VisualStudioUpdater,' but they all do the same thing: let hackers into your computer.
Bitdefender found three versions of RustDoor so far. They're designed to work on both Intel and Apple's chips. The tricky part is that they don't come packaged in the usual ways, making them harder to detect.
Once it's in your system, RustDoor can do a lot of bad things. It can look at what programs are running, run its own commands, create or delete files, and even send your files to the hackers' servers. It's like having a spy hiding in your computer.
The worst part is that RustDoor can stick around even if you restart your computer. It can hide in places where normal users don't usually look, making it hard to get rid of.
Bitdefender has been keeping an eye on RustDoor and they've found clues about how it works. They've even found some of the places it hides on your computer. But it's still a tricky problem to solve.
So, if you're a Mac user, be careful about what you download and install. Even something that looks like a harmless update could turn out to be something much worse. Keep your software up-to-date and be wary of any unexpected messages or prompts, especially if they're asking for your password or permission to install something. Stay safe out there!
