(Reuters) — The Bank of Spain's website has been hit since Sunday by a cyber attack that has temporarily disrupted access to the site, a spokesman for the central bank said Monday.
The spokesman said that the attack has not had an effect on the bank's services or its communications with the European Central Bank or other institutions and that there was no risk of a data breach.
"It is a denial-of-service attack that intermittently affects access to our website, but it has had no effect on the normal functioning of the entity," the spokesman said.
In computing, a denial-of-service attack is a cyber attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the internet.
A report by U.S.-based cyber security firm Malwarebytes Inc. and Osterman Research Inc. found that nearly 75% of companies worldwide suffered cyber attack-related losses in the past 12 months, The Colorado Springs Business Journal. The report found that mid-sized companies experienced greater losses than small or large businesses. Major ransomware attacks that disrupt normal operations or shut down a company's computing infrastructure for a day or more have increased in frequency.
