Be alert, Please do not launch a new tab of Lemmy.World. Having tabs already open with this site is fine but as soon as you do you will be bombarded with awful content with malicious intent to cause shock, disgust and distress.
In the meantime use alternative instances, other instances are not affected by this compromise. Do not open any links/posts from the user MichelleG.
Thanks for reading, please stay safe out there Lemmy users!
Update: Lemmy World is under attack again.
Update: I am not a super code-literate person so bare with me on this… But. Still please becareful. There appears to be a vulnerability.
Users are posting images like the following:
And inside hidden is JavaScript code that when executed can take cookie information and send it to a URL address.
Among other things. At this time if you see an image please click the icon circled before clicking the link. If you see anything suspicious, please report it immediately. It is better a false report than a missed one.
You do you. I would tell my users I have no idea what’s going on, and definitely not say “using your open tabs is probably fine.”
The attack involved a redirect that only affected pages that were freshly opened. If you had tabs that were opened before the attack no redirects happened, no malicious URLs of the sort. It showed the website as it was normal.
That statement was in fact true. The attack only happened when you opened a new tab of Lemmy.World

What happens if you refresh said tab?
