As The Verge and several users found out, Twitter’s new warning label for hacked materials can be tricked to be displayed on any tweet . This is possible if the genuine URL being shared is tuned into a specially crafted one, and shared along with a flagged URL. Twitter is yet to rectify this trick and make the feature useful as intended.
Twitter’s New Warning Label For Hacking

Twitter is one of the popular platforms that’s fighting hard to eradicate misinformation. It has earlier introduced warning labels on sensitive content like COVID-19 and the US elections to avoid people making decisions on unverified information, even though it’s from relevant people and authorities.
Now, it has introduced warning labels on tweets sharing hacking-related information . It starts displaying these labels if the stories are deemed to have any content obtained from hacking or leaked data. While this could be a useful feature, users have found a way to trick this system and display the label on any tweet!
