![]() ![]() “Observed attack sizes range from ~20 Gbps – ~750 Gbps,” Netscout researchers wrote. With an amplification factor of 85.9 to 1, 10 gigabytes-per-second of requests directed at an RDP server will deliver roughly 860Gbps to the target. The technique works by bouncing a relatively small amount of data at the amplifying service, which in turn reflects a much larger amount of data at the final target. ![]() The amplification allows attackers with only modest resources to strengthen the size of the data they direct at targets. So-called booter/stresser services, which for a fee will bombard Internet addresses with enough data to take them offline, have recently embraced RDP as a means to amplify their attacks, security firm Netscout said. RDP is mostly used by businesses to save employees the cost or hassle of having to be physically present when accessing a computer.Īs is typical with many authenticated systems, RDP responds to login requests with a much longer sequence of bits that establish a connection between the two parties. ![]() Typically abbreviated as RDP, Remote Desktop Protocol is the underpinning for a Microsoft Windows feature that allows one device to log into another device over the Internet. DDoS-for-hire services are abusing the Microsoft Remote Desktop Protocol to increase the firepower of distributed denial-of-service attacks that paralyze websites and other online services, a security firm said this week. ![]()
