#1:  Twitter Hack

Three individuals have been arrested in connection with July’s groundbreaking Twitter hack, but we’re not satisfied.
Stolen Bitcoin is still on the move, and it’s hard to imagine that a scammer group that compromised high-profile accounts like Bill Gates, Elon Musk, Apple Inc., and filched more than $110,000 in Bitcoin in a matter of hours would be so easily pinned down.
Will you be the one to track down the money?

#2:   WannaCry Ransomware


WannaCry has caused billions of dollars in damage, and remains one of the highest-profile ransomware attacks of all time. Using EternalBlue to exploit the Server Message Block (SMB) protocol, WannaCry went viral globally in more ways than one, exchanging valuable data for Bitcoin ransom.
Unfortunately, the spoils of this criminal operation are still on the move to this very day. The AnChain.AI threat research team has extracted this Bitcoin address from the
WannaCry ransomware binary:12t9YDPgwueZ9NyMgw519p7AA8isjr6SMw.
