Keytronic confirms data breach after ransomware gang leaks stolen files

Keytronic disclosed a cyberattack on May 6 that disrupted operations and forced a two-week shutdown of domestic and Mexico facilities; investigators confirmed limited data exfiltration including personally identifiable information and Black Basta subsequently leaked ~530GB of stolen data. The company reported material financial impact for the quarter, incurred roughly $600,000 in remediation costs so far, and is notifying affected parties and regulators while Black Basta — a prolific ransomware operation tied to many breaches — claims responsibility.
