MathWorks affected by ransomware attack

Founded in 1984, MathWorks is headquartered in Massachusetts and has more than 34 offices worldwide with more than 6,500 employees. MathWorks develops the MATLAB platform and the Simulink graphical simulation environment that are used by more than 100,000 organizations and 5 million customers.

“MathWorks experienced a ransomware attack. We have notified federal law enforcement of this matter. The attack affected our IT systems. Some of our online applications used by customers became unavailable, and certain internal systems used by staff became unavailable, beginning on Sunday, May 18,” — MathWorks.

Service interruptions caused by the attack still continue (e.g. the cloud center, file sharing, license center, and MathWorks store might be out of service), but the company has already restored some services and addressed third-party cybersecurity experts for assistance.

For several days, users were unable to access their accounts due to problems with signatures, but on May 21, MathWorks restored multifactor authentication and SSO (Single Sign On).

However, some customers are still experiencing problems preventing them from creating new accounts. Additionally, those who haven’t logged in since October 11, 2024, are unable to log in at all.

So far, MathWorks hasn’t released any additional information about the incident. The extortionists behind this attack are unknown; the question whether customer data were compromised remains open. No hacker group has claimed responsibility for the attack yet.
