  This paper investigates the cryptocurrency giveaway scam with the YouTube
live stream carried out on 5/15/2022 and 5/16/2022. In this scam scheme, the
scammer plays a recorded video of a famous person in a YouTube live stream
annotated with a cryptocurrency giveaway announcement. In the annotated
announcement, the victims are directed to the scammer's webpage. The scammer's
webpage is designed intelligently to deceive victims such that they believe the
legitimacy of the giveaway. The scammer claims that whatever donation the
victim sends to a cryptocurrency wallet address, the giveaway scheme will
double the donated amount and immediately send it back to the victim. By
analyzing the scammers' wallet addresses, it can be seen that scammers could
steal a significant amount of money in a short time. After analyzing the
attackers' techniques, tactics, and procedures, this paper discusses the
countermeasures that can be applied to mitigate such a fraudulent activity in
the future.
