So I got a group text message from one of my friends. The same friend that sent the group text also appeared to have sent me a download link of 1 KB in size. I clicked the download link, and then it just disappeared. Gone. Like it was never there. I asked my friend what it was about, and she said she never sent me a link. I checked my download history and nothing is there from today. What is going on? Did I get hacked with a fake text message? How can it just disappear after I clicked it?
