Layer 7 DDoS Attack Prevented by Prolexic

The global leader in Distributed Denial of Service (DDOS) protection services, Prolexic, announced that it mitigated an application later attack for VirtualRoad.org. This web hosting company based in Scandinavia provides a safe web presence for global, independent news media and human rights organizations that are denied freedom of expression in their home countries.

Unlike more common bandwidth floods aimed at the network (Layer 3) or transportation (Layer 4) layers, application layer (Layer 7) attacks can be structured to overload specific elements of an application server infrastructure. Even simple attacks – for example those targeting login pages with random user IDs and passwords, or repetitive random “searches” on dynamic web sites – can critically overload CPUs and databases.

Security Operations Center (SOC) at Prolexic determined with speed the type of attack and discovered that it was launched through a large multi hop proxy network in order to mask the attackers’ source IP address. The company prevented an attack that could have brought down the site for many days or weeks.

“Launching DDoS attacks for politically and ideologically motivated purposes is not new, but is increasing in frequency,” said Neal Quinn, chief operating officer at Prolexic. “This illustrates the ubiquity of DDoS and that targets are no longer limited to high profile commercial web sites.”

As part of an agreement with Prolexic, VirtualRoad.org can leverage resources at Prolexic’s SOC to prevent large and complex attacks that are beyond the capacity and capabilities of its own network and technicians.

“The collaboration between VirtualRoad.org and Prolexic works extremely well because we can leverage Prolexic’s proven experience in protecting large enterprises against DDoS attacks to give our social justice clients more peace of mind,” said Thomas Hughes, director, Media Frontiers, the parent company of VirtualRoad.org. “Our partnership with Prolexic is now a crucial element of our mitigation services, and thanks to Prolexic’s proven expertise, our clients can continue their freedom of expression without disruption, even in an increasingly hostile web environment.”
