A bug in Twitter’s system, which was rectified on Saturday, exposed sensitive information to the company’s advertising team. Names, addresses and credit card information of several advertisers were left exposed, Adweek has learned.
The bug was identified on Thursday by privacy researcher Zach Edwards. He found that the company ingested sensitive credit card information without any encryption. The error occurred in the midst of swift changes to the platform and across-the-board staff cuts in the wake of Elon Musk’s takeover three weeks ago.
