Technology companies last week reported the Internet's largest known denial of service (DoS) attack and are sounding the alarm over a new technique they say could easily cause widespread disruption.
Google said in a blog post published Oct. 10 that its cloud services warded off rogue traffic more than seven times the size of the previous record-breaking attack thwarted last year.
Internet protection company Cloudflare said the attack was "three times larger than any previous attack we've observed."
Amazon's web services division confirmed being hit by "a new type of distributed DoS event."
All three said the attack began in late August; Google said it was ongoing.
The attacks are capable of generating hundreds of millions of requests per second.
All three companies said the attacks were enabled by a weakness in the HTTP/2 network protocol that makes servers particularly vulnerable to rogue requests.
