Telefonica’s Ticketing Trouble: Hackers Run Riot with 2.3GB Data Leak!
Telefonica confirmed a cyberattack on its Jira ticketing system, with 2.3 GB of data leaked online by Hellcat Ransomware. Hackers accessed the system using compromised credentials, bypassing extortion to post directly on Breach Forums. Clearly, cybercriminals are now opting for the no-negotiation route to data exposure.

Hot Take:
Looks like Telefonica’s Jira system decided to take a little cyber vacation without asking for leave. I mean, who wouldn’t want a break from all those tickets? But really, Hellcat Ransomware and friends, we get it. You’re the new kid on the block, but let’s not make data breaches a hobby, okay?
Key Points:
- Telefonica’s internal Jira system was breached with leaked data posted online.
- Hackers used compromised credentials to access 2.3 GB of data.
- No ransom was demanded; the data was leaked without contacting Telefonica.
- The breach is linked to Hellcat Ransomware, also responsible for a Schneider Electric attack.
- Global telecom firms face rising cyber threats, emphasizing the need for robust security measures.
