Reckitt Benckiser -- known for Dettol cleaning products, Nurofen tablets, Durex condoms and more -- has warned that falling victim to the Petya ransomware attack could cost it as much as £100m in lost revenue.
While the attack was successfully contained, efforts to minimise its impact have disrupted manufacturing and ordering systems, impacting on the Reckitt Benckiser's ability to ship products, which the company predicts will cause a two percent drop in net revenue growth -- a figure which could work out to be around £100m.
However, the company believes it is making "good progress" in getting applications and systems back on track and will soon be "trading normally" with customers and partners.
"We believe this issue has now been materially contained, and we continue to work with our IT partners to resolve remaining outstanding items" Reckitt Benckiser said in a statement.
"The attack did disrupt the company's ability to manufacture and distribute products to customers in multiple markets across the RB Group. Consequently, we were unable to ship and invoice some orders to customers prior to the close of the quarter," it added.
The company says it is still assessing the full financial impact of events and hopes to catch up on some of the lost revenue during the next quarter, but that "continued production difficulties in some factories mean that we also expect to lose some further revenue permanently".
One of the first high-profile victims outside of Eastern Europe was Danish transport and energy firm Maersk which shut down IT systems at multiple sites due to the attack. However, the company is now once again operating normally.
"Thank you for your patience and support in light of the recent cyber attack. We are pleased to report that our operations are now running close to normal again," Maersk said in a statement.
Other organisations are still dealing with the outbreak of the Petya epidemic. FedEx's delivery subsidiary TNT Express was hit by the global cyberattack and as of 6 July is still working to return systems to normal.
"Like many other companies worldwide, we are experiencing interference with some of our systems within the TNT network," said a company statement.
"We are implementing remediation steps as quickly as possible to support customers who experience limited interruption in pick-up and delivery operations and tracking systems access," it added.
Very few Petya victims paid the cyberattackers the ransom -- and those who did appear to have done so for no reason as the cyberattack doesn't appear to even allow the hackers to recover lost data.
While the identity of the attackers remains a mystery, Ukraine's interior ministry has said a second cyberattack has been prevented by confiscating the computers and servers of local software firm MeDoc.
It's thought that an update for the firm's tax and accounting software was 'contaminated' by attackers and allowed the Petya outbreak to occur.
