Dive Insight:
The breach of Fortinet customer data marks yet another attack originating in a file-sharing or -transfer service, a common attack vector for opportunistic cybercriminals.
Fortinet is one of the largest cybersecurity companies in the world with a 15% share of the global firewall market, according to Dell’Oro Group. The company ended the second quarter with $380 million in net income on $1.43 billion in revenue.
Fortinet hasn’t disclosed the root cause or named the third-party source of the attack, but the company reported the security incident after a hacker posted details of an alleged leak of Fortinet customer data on a hacking forum.
The company declined to answer questions about how the attacker gained access or when it became aware of the breach.
“The incident did not involve any data encryption, deployment of ransomware or access to Fortinet’s corporate network,” the company said in the blog post.
Fortinet said it terminated the unauthorized individual’s access, contained the incident, notified law enforcement and cyber authorities, and began an investigation into the incident.
Fortinet hasn’t disclosed the attack in a filing with the Securities and Exchange Commission, but said it doesn’t currently believe the incident will have a material impact on its financial condition or operating results.
