Who is the hacker with The Mask?

Could you please clarify who exactly you're referring to as "the hacker with The Mask"? Are you referring to a specific incident or individual in the realm of cryptocurrency or finance, or is it a fictional character from a movie, book, or TV show? If it's the latter, then it's worth noting that "The Mask" is a well-known comic book character and film adaptation, but there's no direct connection to hackers or cryptocurrency in its original narrative. However, if you're asking about a real-life hacker who goes by a similar name or has some connection to "The Mask," I'd need more context or details to provide an accurate description. Could you please elaborate on your question?
