Upon discovering the breach, Cisco denied that its core systems were compromised, attributing the exposure to a misconfigured public-facing DevHub resource. Despite Cisco’s assurances, IntelBroker claimed access until October 18, 2024, and provided evidence to Hackread.com, demonstrating they had exploited an exposed token for JFrog, a software supply chain platform, to access the vulnerable content. This development validated the hacker’s claim and raised significant questions about the efficacy of Cisco’s security measures. The exposed data’s vastness and potential sensitivity added to the gravity of the situation.
Cisco’s Response and Denial
Cisco responded promptly to the initial report, maintaining that their core systems remained uncompromised and isolating the breach to a misconfigured DevHub resource. However, IntelBroker’s claims of extended access and the ability to exploit exposed tokens for further data extraction complicated the narrative. IntelBroker provided evidence to Hackread.com, indicating a more profound breach than what Cisco had asserted. This evidence included clear indications of access to secure, confidential data, providing a tangible glimpse into the compromised security measures.
Despite their firm stance, Cisco’s denial did little to dispel the growing concerns among stakeholders and the public. The company’s reliance on misconfigured resources and exposure to sensitive platforms like JFrog highlighted the underlying vulnerability of even well-established corporations. This breach underscored the necessity for relentless vigilance and continuous evaluation of cybersecurity protocols to safeguard against increasingly sophisticated attacks.
