You are absolutely doing the right thing by asking the question. Whenever you join an airdrop, download a wallet etc... in short whenever you interact with something new, it is always important to determine whether it is safe, and how you could possibly make yourself vulnerable. Eth and crypto in general are still very young and by no means fully explored. Always be vigilant!
Thank you very much. Nice advise to get a new wallet for such transactions. Problem though is that they ask for aboutique 5 or more minimum previous transactions on the wallet to qualify for such airdrops.
Here's a few sources describing what I eluded to above ---> https://themerkle.com/hacker-uses-malicious-smart-contract-to-trick-etherdelta-users/ AND ---> https://medium.com/@rleshner/security-vulnerability-etherdelta-10556d6e72a
There were other more in depth articles which exposed the actual smart contract code that made this exploit possible but they seem to have been wiped, probably to mitigate similar attacks.
I learnt so much going through your links. Have also confirmed my suspicions that you can never tell what is written on the other side. of the contract especially for a non tech like me. It's only wise to be cautious.
Going forward I will have to avoid clicking on links from unknown sources or even google.
Thanks bro
