Telefonica (TEFOF) was among the victims of a ransomware attack aimed at Spanish companies by hackers, Spain's government said Friday, according to Reuters.

In Britain on Friday, hospitals were hit by large-scale cyber attacks, the Guardian newspaper reported. Hacks have disrupted services provided by hospitals, police departments, public transportation systems and utilities in the United States and Europe.

"Telefonica confirmed the attack, saying that it "[affected] the PCs of some employees within the company's internal corporate network".

"Seeing a large telco like Telefonica get hit is going to get everybody anxious".

"Now that the cyber criminals know they can hit the big guys, they will start to target big corporations".

Spain's National Cryptology Centre said in a statement: "an alert relating to a massive ransomware attack on various organisations, which is affecting their Windows systems".

As a client of Telefonica, Iberdrola SA has taken some preventive measures such as switching off computers, a press officer for the company said by phone.

"News (of this attack) has been exaggerated and our colleagues are working on it right now", Chema Alonso, Telefonica's chief data officer and a well-known cyber security expert, said in a message on Twitter.

The energy ministry said it had "confirmation of various cyber attacks targeting Spanish companies", adding the attackers used so-called ransomware which blocks access to files until a ransom is paid.
