The prize notifications that were emailed last weekend contained discount codes and the like as well as information about the UK Monopoly game’s SQL database servers – including plain text passwords. .

“Never trust a clown to secure your connection strings,” tweeted Troy Hunt, operator of the HaveIBeenPwned password-checking service, referring to the fast-food chain’s mascot. He told Bleeping Computer that he became aware of the incident from a victim. He tried the leaked connection string data.
