If you’re wondering why you can’t tweet right now, it’s because hackers have launched a massive cyber attack on a bunch of popular sites.
Cyber criminals have unleashed a massive DDoS (distributed denial of service) attack on the servers of Dyn, a major DNS host.
It has been affecting Spotify, Twitter, Netflix and Reddit all day – and it’s happening again.
Dyn has said it is investigating yet another attack, which is now causing the same huge outages people experienced this morning.
The huge, crippling outage is apparently affecting Europe and the east coast of the US.
This latest outage is very similar to the one earlier today, but it hasn’t been confirmed that the two are directly related.
White House press secretary Josh Earnest said the Department of Homeland Security in the US was ‘monitoring the situation’.
However, he added that ‘at this point I don’t have any information about who may be responsible for this malicious activity’.
Usually this is done by flooding the bandwith and/or resources of the target with traffic.
It then causes the target to temporarily collapse.
What is DDoS attack ?
A distributed denial of service – or DDoS – attack is when someone takes down a site or sites by overwhelming its server with traffic.
Multiple compromised systems are used to target the site or server – which in this case is Dyn.
