Telefónica’s Internal Ticketing System Compromised: A Closer Look
In a recent development, Telefónica, the prominent Spanish telecommunications giant, has acknowledged a breach of its internal ticketing system following the exposure of sensitive data on a hacking forum. This incident raises significant concerns about cybersecurity within large organizations.
Overview of Telefónica
Telefónica is not just any telecommunications provider; it stands as Spain’s largest firm in this sector and operates across twelve countries with a workforce exceeding 104,000 employees. The company is widely recognized under its brand name Movistar in Spain.
Incident Confirmation and Investigation
In correspondence with BleepingComputer, Telefónica confirmed that unauthorized access to their internal ticketing system had occurred. “We have become aware of an unauthorized access to an internal ticketing system which we use at Telefónica,” stated the company representative. They further emphasized that they are actively investigating the situation and have implemented measures to prevent further unauthorized access.
This revelation follows reports that data from a Telefónica Jira database was leaked online by individuals using aliases such as DNA, Grep, Pryx, and Rey.

Details of the Breach
According to one of the attackers known as Pryx, this compromised “internal ticketing system” refers specifically to an internal Jira server utilized for tracking development issues and resolving various operational challenges within Telefónica.
BleepingComputer learned that this breach took place using stolen employee credentials just yesterday. In response to this security lapse, Telefónica acted swiftly by resetting passwords for affected accounts and blocking any further access attempts.
The attackers claimed they managed to extract around 2.3 GB worth of documents including tickets and other sensitive information during their intrusion into the compromised accounts. Notably, some records were associated with customer interactions; however, it appears these tickets were generated using @telefonica.com email addresses—indicating they may represent customer-related inquiries or issues handled internally by staff members.
Pryx also mentioned that there was no prior communication or extortion attempt directed at Telefónica before releasing this information publicly online.
Connection to Ransomware Activities
Interestingly enough, three individuals involved in this breach—Grep, Pryx, and Rey—are reportedly affiliated with Hellcat Ransomware Group—a newly formed ransomware operation making headlines recently for its aggressive tactics against various companies. For instance, Hellcat was implicated in a significant breach involving Schneider Electric where approximately 40GB of sensitive data was pilfered from their JIRA server systems.
As cyber threats continue evolving rapidly across industries worldwide—including telecommunications—the need for robust security measures has never been more critical for organizations like Telefónica who handle vast amounts of personal data daily.
