Telco giant Telefonica has confirmed a breach of its internal systems, with hackers claiming to have stolen over 236,000 lines of customer data.
Four threat actors posted an exfiltrated Jira database on a hacking forum late last week, according to screenshots shared on X (formerly Twitter).
They claimed it contains 236,493 lines of customer data, 469,724 lines of internal ticketing data and over 5000 internal PDFs, Word, PowerPoint and other documents.
