Telefónica is the latest global operator to be targeted by bad actors after hackers breached its internal ticketing system.
BleepingComputer reports that Telefónica admitted its systems had been breached, with the operator “currently investigating the extent of the incident”.
Telefónica said it has taken “necessary steps to block any unauthorised access” to the Jira-based ticketing server used by the operator for reporting internal issues.
Four attackers, Pryx, Grep, Rey, and DNA, made off with around 2.3 GB, according to posts on the hacking site BreachForums.
