The Wormhole Bridge Attack

Another giant cryptocurrency hack this year was the Wormhole bridge attack. A decentralized finance (DeFi) platform that helped customers with asset transfer, Wormhole was quite the success story for a time. Unfortunately, in February, someone hacked it, and *poof* $325 million in crypto went up in smoke. Oddly, the hacker later returned a lot of the funds, but the whole thing remains an example of how money can evaporate in the course of a day when it comes to the DeFi world.
