She said European Banking Authority: The hackers targeted the European banking regulator, but no data was obtained.
The authority said it is redoubling its efforts to protect itself amid a global cyber attack that exploits flaws in the mail server program from a company Microsoft.
The European banking regulator, which collects and stores large amounts of sensitive data about banks and lends them, said he believed that the cyber attack only infected his e-mail servers.
The European banking regulator added: The investigation has not revealed any data theft so far, the e-mail infrastructure has been secured, and the analyzes indicate that no data extraction has been carried out, and we have no indication that the breach has bypassed our e-mail servers.
The European Banking Authority is the latest high-profile victim among tens of thousands of organizations in Asia and Europe to have been targeted by a campaign Microsoft says it uses unexplored vulnerabilities in various versions of its mail server software.
And the breaches continue despite the emergency patches issued by Microsoft, which said: It is working with government agencies and security companies to help customers.
However, one examination of connected devices showed that only 10 percent of exploitable devices had had the corrections installed by Friday, even though the number was on the rise.
Microsoft blamed the first wave of attacks on Hafnium, a group backed by the Chinese government, and a Chinese government spokesman said: The country was not behind the incursions.
What began as a controlled attack late last year against a few classic espionage targets last month has grown into a full-scale campaign.
More attacks are expected from other hackers as the code used to control mail servers spreads.
It appears that all affected people are running the web versions of the Outlook email client and hosting them on their own devices, rather than relying on cloud service providers.
Microsoft explained that Hafnium is highly sophisticated, and has previously targeted US-based companies, including infectious disease researchers, law firms, universities, defense contractors, think tanks and NGOs.
