Japanese technology giant Olympus has confirmed that it was hit by a cyberattack over the weekend that forced it to shut down its IT systems in the US, Canada and Latin America.

In a statement on its website, Olympus said it is “investigating a potential cybersecurity incident detected on October 10” and “is currently working with the highest priority to resolve the issue.”

“As part of the investigation and prevention, we have suspended the affected systems and notified the relevant external partners. The current results of our investigation indicate that the incident was rooted in the US with no known impact on other regions.”


“We are working with the appropriate third parties on this situation and will continue to take all necessary measures to securely serve our customers and business partners. Protecting our customers and partners and maintaining their trust in us is our top priority. Our investigation is ongoing and we are committed to transparent disclosures and will continue to provide updates as new information becomes available.”

This is similar to a statement made by Olympus last month after cyberattacks on its European, Middle East and Africa networks.

At the time of the attack, Olympus also said it was “investigating a potential cybersecurity incident.” A person with knowledge of the incident told Nerdshala that Olympus was recovering from the ransomware attack. A ransom note left on infected systems was also linked to the Blackmatter ransomware-as-a-service group.

Ransomware expert and Emsisoft threat analyst Brett Callow told Nerdshala that this latest incident occurred over the weekend — often when gangs deploy ransomware frequently, including on holidays — raising the potential for a repeat attack. “And if it is ransomware, is it blackmatter then it is impossible to say again. It certainly could be, or the affiliate responsible for the attack on EMEA operations could have chosen to deploy the ransomware differently this time around,” They said.

When reached, Olympus spokeswoman Susan Scurbo did not immediately comment. We’ll update as we learn more about Olympus’ security incident.
