A major cybersecurity company was just hacked and lost 440GB of data.

The world-famous cybersecurity company Fortinet has just officially confirmed that a large amount of user data was stolen from the company's Microsoft Sharepoint server, and was posted on a hacker forum early in the morning of September 15.

Accordingly, the hacker behind this daring attack, nicknamed “Fortib**ch”, shared the login information to an S3 storage (digital box for storing files online) for others to access and download. This leaked data warehouse claims to have a total capacity of up to 440GB.

Although the threat actor attempted to extort Fortinet, the company's management refused to pay. The Sunnyvale, California-based cybersecurity company has been proactive in contacting customers affected by the security incident, but has not yet officially confirmed the specific amount of data the threat actor stole.

Responding to the media, a representative of the cybersecurity company Fortinet said: "An individual illegally accessed a limited number of files stored on a third-party cloud file share drive on Fortinet, including limited data related to our customers."

Fortinet has not yet confirmed how many users were affected, but said the incident primarily affected users in the Asia-Pacific region, but did not disrupt the company's operations, and all services are still operating normally.

The company develops and sells network security solutions such as VPN services, firewalls, endpoint security, and intrusion detection systems.
