Meta has paused an internal program, the Model Capability Initiative (MCI), that tracked employees’ clicks and keystrokes to train artificial intelligence after sensitive data was inadvertently exposed within the company. An internal security notice sent to U.S.-based employees on Monday revealed that data, including “full prompts and transcriptions, private conversations, people and performance data,” was not properly protected. “We have carefully designed this program with privacy safeguards, and while we have no indication at this time that any data was improperly accessed by Meta employees, we’re pausing it while we investigate,” a Meta spokesperson said. The program, which also collects screenshots of employees’ computer screens, was introduced in April to improve AI models in areas like “choosing from dropdown menus ​and using keyboard shortcuts.” In May, more than 1,600 employees signed an internal petition opposing the program, citing “the potential for breaches and unauthorized disclosure.” One employee described themselves as “incensed,” stating, “I don’t see any evidence of malicious access, but the fact that this data wasn’t locked down as originally promised is super frustrating.” Sources told Wired the incident has since been marked as closed. The incident follows a similar exposure earlier this month where hackers tricked Meta’s AI support chatbot into changing passwords for 20,225 Instagram profiles.
