It's a nice catch OP, that's why I barely join giveaways or even airdrops, they are prone to that fraudster and it might also fake sites that contained malware infections. We should always look into the official website announcement and most importantly, avoid any telegram group or any social media groups that keep spreading fake events.
For airdrop after what I did, there are indeed many that are still legitimate, but if it is only doing the job, you can do it if the rest is more than that then it is necessary to avoid sometimes being told to stare at the software and that's where to be more careful even though the malware is always inserted in the application.
