U.S. President Barack Obama told a late-night talk show host Tuesday that his administration is taking steps to prevent cyber-attacks like the one last week that shut down some of the world's most popular and widely-used websites – such as Twitter and Netflix – but he acknowledged that investigators had "no idea" who carried out the attack.
Obama addressed the cyber-attack during an episode of "Jimmy Kimmel Live." He said that the Department of Homeland Security held a conference call with 18 major communication service providers following the incident, and is developing a new set of “strategic principles” for securing internet-connected devices.
On Friday morning, millions of internet users in the U.S. got a surprise when they attempted to log in to the world's most popular websites, like Twitter and Netflix, and found that a massive cyber attack rendered them unable to connect. And if that was not enough, the sites went down again later in the day, falling victim to another attack.
Cyber-security has become a central issue in the U.S. presidential campaign, with the Democratic nominee repeatedly blaming Russia for hacking into her and her campaign manager's emails.
The Republican candidate Donald Trump has said that cyberattacks from foreign governments and organized criminal groups constitute one of our most critical national security concerns, while his rival Hillary Clinton of the Democratic Party, has said cybersecurity is going to be one of the biggest challenges for the next president.
