Massive Cisco Data Breach: IntelBroker Claims to Steal Developer Data from Microsoft, SAP, Barclays, and More

IntelBroker, a known hacker, claims a major breach of Cisco’s systems, allegedly exposing sensitive developer data from companies like Microsoft, SAP, and Barclays. Learn more about the alleged October 2024 data breach and its potential impact on cybersecurity.

A notorious hacker known as IntelBroker recently claimed responsibility for a major breach at Cisco, saying they infiltrated the company's systems on October 6, 2024, and stole sensitive data. Posting on BreachForums, IntelBroker and two accomplices allege they accessed a trove of confidential information, including source code, hardcoded credentials, API tokens, digital certificates, and even customer documents.

IntelBroker’s post suggests that this data may impact major companies, potentially compromising information linked to developers at Microsoft, Barclays, SAP, T-Mobile, Verizon, and AT&T.

Cisco responded, acknowledging the allegations and confirming they’ve launched an investigation. A Cisco spokesperson stated, “We have launched an investigation into this allegation, and our investigation is ongoing.” While they haven't yet found evidence of compromised systems, Cisco is working with law enforcement and has committed to notifying any affected customers if necessary.

IntelBroker's reputation lends weight to these claims. Known for high-profile breaches, including previous attacks on General Electric, T-Mobile, and AMD, IntelBroker’s history suggests this incident could be significant, even if some past claims have been overstated. Allegedly, more than 800 companies are mentioned in the leaked documents.

This incident brings to light the challenges of protecting developer and cloud environments, especially from third-party risks. As Cisco investigates, businesses should remain vigilant, reviewing their security protocols and staying alert for signs of possible compromise.

Key Points:

1. Breach Claims: IntelBroker alleges they breached Cisco on October 6, 2024, accessing sensitive data.
2. Affected Companies: Companies like Microsoft, SAP, Barclays, T-Mobile, and AT&T could be impacted.
3. Cisco's Response: Cisco is actively investigating and will update customers if their data is at risk.
