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 to spread the word!!!
I got this message from a comment on the day 2 of Scratch week project on @ScratchCat's profile. It may be a good idea to report any accounts that have been hacked. For more information see https://scratch.mit.edu/projects/1315831433/ or https://scratch.mit.edu/projects/1315772178/
