Orange Group, one of France’s largest telecommunications providers, has suffered a significant data breach, exposing sensitive corporate and customer information. A hacker operating under the alias “Rey,” affiliated with the HellCat ransomware group, leaked thousands of internal documents on a dark web forum. This breach raises concerns about cybersecurity vulnerabilities in major telecom firms, particularly as it was facilitated through compromised credentials and software exploits.
Adding to the severity, a separate cyberattack on Orange Spain disrupted its network infrastructure via a Border Gateway Protocol (BGP) hijacking. These incidents highlight critical weaknesses in both corporate data security and internet routing protocols.
the Breach
- Hacker and Data Leak: A threat actor known as “Rey,” linked to the HellCat ransomware group, leaked 12,000 internal Orange Group files (6.5GB) on a dark web forum. The breach exposed source code, invoices, contracts, and partial payment card details.
- Attack Method: Rey gained prolonged access to Orange Romania’s systems by exploiting vulnerabilities in Jira and internal portals, leveraging stolen credentials. Over a month of undetected access led to data exfiltration on February 25, 2025.
- Leaked Data: 380,000 unique email addresses, employee records, and project documents were compromised. While much of the payment card data was outdated, the breach still posed reputational risks.
- Corporate Response: Orange confirmed the breach stemmed from a “non-critical back-office application” in Romania. The company launched an investigation and pledged transparency in compliance with legal obligations.
- Secondary Breach (Orange Spain): On the same day, a separate hacker, “Snow,” hijacked Orange Spain’s RIPE NCC account, manipulating BGP routing and RPKI settings. The attack, caused by weak credentials and a lack of multi-factor authentication (MFA), led to a three-hour network disruption.
- Industry-Wide Risks: Researchers found over 1,500 compromised RIPE, APNIC, and LACNIC credentials for sale on the dark web, showing how widespread credential theft enables cyberattacks.
What Undercode Say:
A Deep Dive into the Orange Group Cybersecurity Failures
Orange Group’s breaches are a stark reminder of the evolving cyber threat landscape, particularly for telecom providers. This case highlights several key cybersecurity failures that companies must address to prevent similar incidents in the future.
1. Exploiting Known Weaknesses: Jira and Credential Mismanagement
Rey’s ability to infiltrate Orange’s systems relied on well-known cybersecurity failures: unpatched software vulnerabilities and weak credential management. Jira, a popular issue-tracking platform, has been targeted in multiple cyberattacks due to misconfigurations and delayed security patches.
Organizations often fail to implement strict access controls, allowing attackers to move laterally within systems once they breach a single point of entry. If Orange had enforced least-privilege access and stronger authentication mechanisms, Rey’s prolonged access could have been prevented.
2. Data Exfiltration Without Detection: A Security Oversight
One of the most alarming aspects of this breach is how Rey operated within Orange’s network for over a month without detection. This suggests a lack of effective network monitoring and anomaly detection. Modern Security Information and Event Management (SIEM) tools should have flagged unusual access patterns, particularly for sensitive databases.
A three-hour data exfiltration event should not go unnoticed. Companies must implement real-time data loss prevention (DLP) mechanisms and behavioral analytics to catch unauthorized data transfers before they escalate.
- BGP Hijacking: The Achilles’ Heel of Internet Infrastructure
The attack on Orange Spain highlights a separate but equally concerning issue: the fragility of global internet routing. BGP hijacking, where hackers manipulate routing tables to redirect traffic, has been exploited in previous cyberattacks, often leading to service disruptions or data interception.
This incident could have been avoided with stronger authentication measures on Orange’s RIPE NCC account. The fact that an admin account was protected by a weak password (“ripeadmin”) and lacked MFA is a glaring security lapse. Such misconfigurations are inexcusable for an organization managing critical internet infrastructure.
4. The Dark Web’s Role in Facilitating Cyberattacks
The discovery of over 1,500 compromised telecom credentials for sale on dark web forums underscores the ease with which attackers obtain access to critical systems. Many of these credentials are harvested through info-stealer malware, such as Redline and Lumma, which infect employees’ personal devices.
Organizations must take a proactive stance by monitoring dark web markets for leaked credentials and enforcing strict separation between personal and corporate accounts. Cyber threat intelligence should be a core part of security operations.
5. Reputational and Financial Fallout
While Orange claims the breached payment data was outdated, the exposure of internal contracts and source code has long-term implications. Leaked source code can aid future attacks by revealing vulnerabilities, while contract disclosures may harm business relationships.
Moreover, the repeated failure to secure critical systems can erode public trust. Orange, like other telecom giants, is responsible for safeguarding not just its own data but also the infrastructure that supports millions of users. Regulatory bodies may impose fines, and customers may seek alternative providers if security incidents persist.
6. The Need for a Security-First Culture
The Orange breaches reveal systemic failures in cybersecurity culture. Stronger authentication measures, continuous vulnerability assessments, and improved employee cybersecurity training could have mitigated these attacks.
Companies must shift from reactive to proactive cybersecurity strategies. This means:
– Enforcing MFA for all privileged accounts.
– Regularly auditing software configurations (e.g., Jira).
– Deploying endpoint detection and response (EDR) solutions.
– Conducting simulated phishing and credential theft drills.
– Monitoring dark web markets for leaked credentials.
Final Thoughts: A Wake-Up Call for Telecom Security
Orange’s twin breaches serve as a warning for the entire telecommunications industry. Cybercriminals are evolving their tactics, leveraging known vulnerabilities and weak credentials to infiltrate critical networks.
As cyberattacks grow more sophisticated, telecom providers must invest in stronger defenses, not just for compliance but for the integrity of the digital infrastructure millions rely on. Security should not be an afterthought—it must be an integral part of corporate strategy.
