Cisco Source Code and Customer Data Breach Highlights Supply Chain Risks

A threat actor is selling stolen Cisco proprietary source code for critical network infrastructure systems (IOS, ASA, NX-OS) along with 3.15 million Salesforce customer records. This breach represents a severe supply chain compromise that could enable attackers to discover zero-day vulnerabilities in widely-deployed network equipment. The exposure of both intellectual property and customer data demonstrates how high-value targets face multi-faceted attacks that threaten both their own operations and their customers' security. Organizations relying on Cisco infrastructure may face increased risks as attackers study the leaked source code for exploitable weaknesses.
