Ardagh Group said that cyberattack on the packaging group in May led to a $34 million overall financial hit.
The glass and metal containers group said it was hit by a cyberattack on May 17 that forced it to shut down some of its systems as a precautionary measure.
Its Ardagh Metals Packaging (AMP) unit incurred about $16 million of the costs it had to endure as a result of the attack.
“Key systems have now been brought back online securely in a phased manner and in line with our plan,” it said.
“Production at all of our manufacturing facilities continued to operate throughout this period, though we experienced some shipping delays as a result of this incident.
“We have already taken various steps, including engaging leading industry specialists to conduct a forensic investigation of our systems and introducing additional protection tools across our network to further enhance the security of our IT systems.”
