An old protocol found in SOHO routers may be responsible for recent DrDoS attacks, says the security steam at Akamai. Akamai, through the company’s Prolexic Security Engineering & Research Team (PLXsert), issued an alert today for an old protocol that could be used in Distributed Reflection Denial of Service attacks (DrDoS) attacks. Routing Information Protocol v1 (RPIv1) allows routers in small networks to share route information. For example a router running RIPv1 would send a request over UDP 520 when it is first powered on and other devices on the network, listening for this request, would send the new router a list of routes. In this case the list of routes would be sent instead to a designated target. It has since been replaced with RIPv2 but many older units still have RIPv1 enabled by default. “This version of the RIP protocol was first introduced in 1988 – more than […]
The security firm Akamai issued an advisory to customers on Thursday warning that a new software tool for managing distributed denial of service (DDoS) attacks was leading to a resurgence in large-scale attacks that use Simple Network Management Protocol (SNMP) traffic to overwhelm web sites. The Threat Advisory (reg wall) was issued by Akamai’s Prolexic Security Engineering and Response Team (or PLXsert). According to the advisory, Akamai began noticing a resurgence in DDoS attacks using SNMP on April 11. The company said that firms in industry verticals including consumer goods, gaming, online hosting and Software-as-a-Service and non-profits had all been targeted. [Read more Security Ledger coverage of DDoS attacks here.] The company has identified new- and updated tools in the cyber underground, including one dubbed SNMP Reflector – that are enabling the attacks. Simple Network Management Protocol (SNMP) is a protocol that is used for managing devices on a network including […]
