Know Your Breach: NTT Com
Mar 13, 2025 8:33:43 AM
The Target: The Japanese information and communication technology provider NTT Communications Corporation (NTT Com).
The Take: The threat actor, the company says, exfiltrated information on 17,891 customer companies, including contract numbers, customer names, contact names, phone numbers, email addresses, physical addresses, and information on service usage.
The Vector: The incident, the telecoms firm says, occurred on February 5, when an unnamed threat actor accessed its internal systems, including those hosting information on services provided to customer companies.
This breach highlights the extreme importance of timely software updates for known software vulnerabilities, not only in systems directly under a firm’s control, but in third-party systems the firm relies upon as well. The longer a firm, or its vendors, hold out on deploying the most up-to-date software for their systems, the greater the chance an attacker will exploit the issue.
