Canvas virus explained

Projects from people who are getting hacked shows to see inside and go to backdrop for a surprise but if you do you become infected with the hack and you cant gain access back to your acc,its called the canvas virus and don't get it! #stopcanvasvirusnocanvasvirus,BEWARE, A group of hackers has created malware that we have dubbed ‘the canvas’ virus. The virus lurks inside of infected projects, it tells you to see inside and open the backdrop editor. DON'T DO THIS, You will receive a message alerting you that you've been hacked, and will be signed out of your account. Your projects will be replaced with the infection and your profile changes. Be safe, stay alert, and report. Copy to spread the word!!!! More infos : https://scratch.mit.edu/discuss/topic/882127/

Recently, there has been a lot of confusion about what the ‘Canvas virus’ is and i want to clear that confusion away by making this topic.
Most confusion comes from copy/pasted warnings in the comments section of projects (mostly featured ones)
Here is one example:
SCRATCHERS BEWARE, A group of hackers has created malware that we have dubbed ‘the canvas’ virus. The ‘Canvas’ virus lurks inside of projects of the infected, it tells you to ‘see inside’ and open the backdrop editor. DO NOT DO THIS, You will receive a message alerting you that you've been hacked, and will be signed out of your account. Your projects will be replaced with the infection and your profile description changes. Be safe, stay alert, and report. Copy and paste" SPREAD THE WORD!!
The comments give already sort of an answer about the situation, but it's still very vague and that copy/pasting is mostly used to spread misinformation.

The ‘virus’ actually explained
So, it's actually not a virus, but a vulnerability/exploit that has affected many Scratchers.
It works by going into the project editor (or clicking ‘see inside’) and then going to the costume/backdrop editor. When you open it, the costumes can actually do Arbitrary Code Excecution, which is a way that code can be excecuted. In the desktop/offline editors, it's even worse because then they can run malicious shell programs and steal data from you! And this is not a theoretical possibility, it has already affected multiple Scratchers.

What it can do
It can delete and/or hack all projects, change the description of the victim's profile, comments things on the victim's profile without their concent and run malware (only on desktop/offline editors).

How to prevent it
Don't open suspicious projects asked by others to open and avoid any random links.
If you did get hacked: Unshare all projects, change your password and delete any comments that you didn't type ASAP.

Here is a blog post by GarboMuffin that also explains it.

Sadly, no. The ST is hard-working to fix it.
