Outbound DDoS: NETSCOUT’s Roland Dobbins Warns of a Hidden Threat to Operators, Podcast

Telecom Reseller / Technology Reseller News

“Availability is resilience. If you can’t see it, you can’t secure it.” — Roland Dobbins, Principal Engineer, NETSCOUT ASERT Team

In this Technology Reseller News podcast, Doug Green, Publisher of TR Publications, speaks with Roland Dobbins, Principal Engineer on NETSCOUT’s ASERT (Arbor Security Engineering & Response Team), about the growing risk of outbound DDoS attacks—and why service providers and enterprises must defend against threats moving in every direction.

NETSCOUT, a global leader in network visibility and DDoS defense, has been monitoring an alarming surge in outbound and cross-network (east-west) attack traffic driven by new “Turbo Mirai” botnets, particularly the Aisuru variant. These attacks can exceed 20 terabits per second and 6 gigapackets per second, overwhelming even the largest operators. Dobbins explains that while most organizations focus on protecting against incoming DDoS traffic, outbound attack streams can be just as damaging, clogging peering links and taking down critical infrastructure.

“We’re seeing broadband networks unintentionally launching massive attacks, sometimes over a terabit per second, because of compromised IoT and connected devices,” Dobbins said. “It’s not just about defending the target — it’s about protecting your own network from being part of the problem.”

NETSCOUT’s ASERT team, which observes 40,000–50,000 DDoS attacks daily across 60% of the world’s IPv4 space, provides continuous research and live mitigation guidance to customers worldwide. Dobbins emphasized that effective DDoS defense requires edge-to-edge visibility, sub-second detection, and suppression of both inbound and outbound traffic.

“You can’t secure what you can’t see,” he added. “Operators need full visibility across their networks, with active mitigation built into daily operations.”
