West Pharmaceutical Services Hit by Disruptive Ransomware Attack

West Pharmaceutical Services, a Pennsylvania-based pharmaceutical packaging and delivery systems manufacturer, is working to restore operations following a ransomware attack on May fourth that disrupted business globally. The company proactively shut down affected systems, enlisted Palo Alto Networks' Unit 42 for incident response, and confirmed that attackers exfiltrated data before deploying ransomware, though they've since taken steps to mitigate the risk of that data being released—suggesting possible ransom negotiations. While core enterprise systems and some manufacturing operations have been restored, the company hasn't determined the full extent of the breach or its financial impact, and no ransomware group has publicly claimed responsibility.
