PeopleDAO loses $120,000 after payment spreadsheet is shared publicly

PeopleDAO is the successor to ConstitutionDAO, a group that made an ill-fated attempt to buy a copy of the US Constitution in November 2021. When the accounting lead for PeopleDAO accidentally shared an editable accounting spreadsheet link in a public Discord channel, an enterprising member of the Discord decided to take advantage. They inserted a row with their own wallet address for a 76 ETH (~$120,000) payment, then hid the row so it wouldn't display to the other viewers.

When team leads reviewed the spreadsheet to sign off on the payments, they didn't see the row, and there was no rollup showing total payments or anything else that would've helped them catch the malicious activity. The transactions were uploaded to a tool allowing asset transfers via CSV, and the required six out of nine multisig members approved the transaction.

PeopleDAO have reported that they're working with various security researchers to track the funds, and have reported the theft to the FBI and FTC.
