Major Data Breach At Cisco: Intel Broker Steals 4.5 TB Of Value Data

The hacker group “Intel Broker” has successfully breached Cisco’s network, allegedly claiming to have exfiltrated approximately 4.5TB of sensitive data tied to various Cisco products. The breach reportedly occurred after Cisco inadvertently left its DevHub instance exposed, granting unauthorized access to critical systems.

Threat actors identified as “@zjj,” “@IntelBroker,” and “@EnergyWeaponUser” are said to have exploited this vulnerability, downloading sensitive files and sighting poor security at major institutions. IntelBroker has since claimed responsibility for the breach and the hackers are alleged to offer the data for sale on the dark web.

The exposed data includes proprietary Cisco products such as

Cisco C9800-SW-iosxe-wlc.16.11.01,

Cisco IOS XE & XR,

Cisco Identity Services Engine (ISE),

Cisco Secure Access Service Edge (SASE),

Cisco Umbrella, and

Cisco Webex.

Hackers have shared some files with the cybersecurity community to validate their claims and attract buyers for a purported “full version” of the stolen data.

If the breach is confirmed, it could lead to serious implications for Cisco’s business. Proprietary software and platforms like Webex and Umbrella may face exploitation risks, while organizations relying on these products could encounter vulnerabilities. Cybersecurity experts are urging users of Cisco technologies to remain vigilant and monitor for security updates or patches. Cisco has not yet commented publicly on the breach, leaving the industry closely monitoring its response and future security measures.

When it comes to cybersecurity, one shouldn’t blink at the possibility of a hack. Targeted attacks such as these not only affect the organization itself but also its clients in extension. There are multiple ways to keep your data secure, but Secucenter offers you a more concentrated solution called SOC monitoring. Our SOC engineers will be proactive in monitoring your systems and endpoints for unusual activities and report in case it is detected. This has been beneficial for businesses, allowing them to clock out or take a break without worrying about exposing their confidential information.
