It's Not Safe to Click Links on X (lifehacker.com)

As noted by security researcher Will Dormann, some posts on X purport to lead to a legitimate website, but actually redirect somewhere else. In Dormann's example, an advertisement posted by a verified X user claims to lead to forbes.com. When Dormann clicks the link, however, it takes him to a different link to open a Telegram channel that is, "helping individuals earn maximum profit in the crypto market," he said. In short, the "Forbes" link leads to crypto spam

Damn, a security researcher discovered what was known from late 1990's/early 2000's: a link on a webpage could take you in a place that it is not the one the link say it will be.

I get the knee-jerk jaded cynicism but this is a little more nuanced than that.

"All they have to do is set up two different URL destinations in their post. In the case outlined above, clicking the forbes.com link actually takes you to joinchannelnow.net. Once on this site, the server checks to see whether the request is coming from a typical browser (that's you). If so, it'll take you to the spam site, which for this situation is a crypto scam Telegram channel. However, if the server detects the request is coming from something else—like a X link-verifying bot—it'll assume the request is not being made by a human; in these cases it returns a legitimate URL. So, even though the first link is to joinchannelnow, X checks it and is taken to forbes.com, and so it places that URL preview on the post. You're experience will be different."
