The internet around the globe has been slowed down in what security experts are describing as the biggest cyber-attack of its kind in history.
“Based on the reported scale of the attack, which was evaluated at 300 Gigabits per second, we can confirm that this is one of the largest DDoS operations to date,” online security firm Kaspersky Lab said in a statement, “There may be further disruptions on a larger scale as the attack escalates.”
It is having an impact on popular services like Netflix – and experts worry it could escalate to affect banking and email systems.
Spamhaus, a group based in both London and Geneva, is a non-profit organisation that aims to help email providers filter out spam and other unwanted content.
To do this, the group maintains a number of blocklists – a database of servers known to be being used for malicious purposes.
Recently, Spamhaus blocked servers maintained by Cyberbunker, a Dutch web host that states it will host anything with the exception of child pornography or terrorism-related material.
Spamhaus said it was able to cope as it has highly distributed infrastructure and technology in a number of countries.
