Olympus, a leading medical technology company, is investigating a "potential cybersecurity incident" that impacted some of its EMEA IT systems last week. Olympus has more than 31,000 employees worldwide and over 100 years of history developing for the medical, life sciences, and industrial equipment industries. While Olympus did not share any details on the attackers' identity, ransom notes left on systems impacted during the breach point to a BlackMatter ransomware attack. The same ransom notes also point to a Tor website the BlackMatter gang has used in the past to communicate with victims.
