SLP

(Service Location Protocol) An IETF standard used to announce and discover services such as printers and file shares on an IP network. Apple used SLP prior to Mac OS 10.2, but migrated to its Bonjour technology. SLP is also used in SIP-based IP telephony applications. SLP addresses are formed like a URL, and SLP packets are typically transmitted over UDP.

User, Service and Directory Agents
An SLP "user agent" (UA) process runs in the client that queries a "service agent" (SA), which advertises its available service. In large networks, a "directory agent" (DA) caches services to improve performance, and user agents and service agents must use the directory agent if present. See SSDP and SIP.

The five most commonly used in attacks were the Domain Name System (DNS) protocol, the Network Time Protocol (NTP) based weapons, the Simple Service Discovery Protocol (SSDP), Simple Network Management Protocol (SNMP) and the Trivial File Transfer Protocol (TFTP), this last of which is a new entrant into the top five.
While the most prevalent types of weapons leverage other more established technologies and internet protocols, such as the Network Time Protocol (NTP), Domain Name System (DNS) resolvers, and the Simple Services Discovery Protocol (SSDP), CoAP-based devices represent a fast-emerging new weapon type in botnet arsenals, according to the report.
