Widespread cyberattack takes down sites worldwide
A number of popular websites like Twitter and Netflix went down for some users on Friday in a massive cyber attack with international reach.
Dyn, which manages website domains and routes internet traffic, experienced two distributed denial of service attacks on its DNS servers. A DDoS attack is an attempt to flood a website with so much traffic that it impairs normal service.
“If you take out one of these DNS service providers, you can disrupt a large number of popular online services, which is exactly what we’re seeing today,” said Jeremiah Grossman, chief of security strategy at cybersecurity startup SentinelOne.
