PeopleDAO, a decentralized autonomous organization created to buy a copy of the U.S. Constitution, lost 76.5 ETH due to a mistake by the chief accountant who accidentally sent a link to a Google Table with monthly payments to participants (with editing rights) to an open channel on the project's Discord server.
Since the link provided editing rights to the document, the attacker inserted his address and payment amount into it, and then made the line invisible. The incident happened on March 6, PeopleDAO representatives reported it five days later on the project's Twitter.
