With Anveo and now Callcentric being hit in the past few weeks, I hope we are not seeing a new trend begin to form.
This has already been posted, but it bears fuller posting on this page:
DDoS attacks reach new level of sophistication
Prolexic Technologies warned of an escalating threat from unusually large and highly sophisticated DDoS attacks.
The DDoS attacks have been launched in the last week using the so-called itsoknoproblembro DDoS toolkit. The malicious actor(s) behind the attacks have used this potent tool in conjunction with sophisticated attack methods that clearly demonstrate knowledge of common DDoS mitigation methods.
The attack signatures are extremely complex and Prolexic has recorded sustained floods peaking at 70 Gbps and more than 30 million pps against some of its customers. Most mitigation providers would struggle to combat DDoS attacks with these characteristics....
As was said, Anveo was recently hit by an attack, now CallCentric.
Both are companies that know what they are doing and that keep on top of their networks. So [anyone] could be next.
Here is an article from LAST October:
Massive DDoS attacks a growing threat to VoIP services
When the massive distributed denial-of-service (DDoS) attack in March brought down the voice-over-IP (VoIP) call processing supplied by TelePacific Communications to thousands of its customers, it marked a turning point for the local-exchange services provider in its thinking about security.
The massive DDoS attack came blasting in from the Internet in the form of a flood of invalid VoIP registration requests. The attack resulted in widespread service disruptions for a number of days in late March and cost the company hundreds of thousands of dollars in customer credits....
....Much of the DDoS attack streams did appear to be originating from China. But even if a botnet based on compromised Chinese computers was the source of the attack, that does not necessarily mean that someone in China is the culprit originating it, though that is a possibility....
This is the age of Stuxnet, Flame, and Gauss
. And no, that is NOT a law firm.
Some of these attacks can involve being hit by thousands of zombie/botnet machines at once. As the intensity of attacks increases, defenses will have to as well.
This is from a while back, a video representation of an attack.
The POTS/PSTN networks may not be quite as prone to this exact type of attack, but they will be targeted sooner or later too.
All the more reason to use providers like CC who keep on top of things....
