Snack giant Mondelez International has confirmed that the Petya ransomware virus was to blame for its global IT network outage.
Other multinational companies have been affected by the malicious software which locks up computer files and demands a bitcoin ransom to unlock them.
"At this time, we can confirm that the virus has been isolated, and that the issue is contained," the company said in a statement last week.
In the company's latest statement it said it "continues to make progress to fully restore its operations following the cyber hack that affected a number of large, global companies and private organisations".
"While there is still work to be done, we continue to restore functionality to a number of key systems and remain focused on executing business continuity plans. We are dedicated to delivering our products to customers and minimising disruptions in the interim," the food giant said.
"We will work closely with customers and business partners as we continue to normalise our operations. The company has also engaged outside specialists, including IT partners and global cyber security agencies and experts, to mitigate impacts of this incident and safeguard systems going forward."
