Leaks from Hackers Cisco Information

In October, the infamous hacker IntelBroker said that he and other others had gained access to Cisco networks and taken encryption keys, source code, credentials, certificates, and private documents. The hacker asserted that they had acquired source code linked to a number of significant businesses. Cisco's inquiry revealed that its systems had not been compromised and that the data came from a DevHub environment that is open to the public and acts as a resource center where users can access scripts, source code, and other materials. 

The networking behemoth pointed out that although most of the data stored in the DevHub environment was accessible to the public, the hackers also managed to get their hands on some files that weren't meant for public download and were unintentionally posted on the website because of a configuration mistake. Cisco has since deleted the claim that it had no proof that private data, including financial or sensitive personal information, had been compromised from its incident reports. 

According to IntelBroker, which released 2.9 GB of data on Monday, the disclosed files are related to Cisco's Catalyst, IOS, Identity Services Engine (ISE), Secure Access Service Edge (SASE), Umbrella, and WebEx products. The data was taken from the Cisco DevHub instance. JavaScript, Python, and other source code files, along with certificates and library files, are among the disclosed data that was shared on the BreachForums cybercrime site.

According to the hacker, the DevHub instance contained 4.5 Tb of data. Although the hacker is known, IntelBroker earlier stated that 800 GB of files were taken.
