DoS and DDoS Attacks

This section covers Peresvet ST client plugins for emulating DoS and DDoS loads: TCP/UDP floods, GRE/DNS/DHCP floods, ICMP/Ping/amplification/fragmentation, and the combined MHDDoS Emulation plugin. Use these plugins to test network resilience, filtering, and security controls in an isolated test environment.

Most flood plugins are stateless / one-arm: traffic is sent from an agent to the DUT. MHDDoS Emulation combines several vectors in one plugin and lets you enable each subplugin independently.

Group	Plugins (catalog)
TCP Flood	SYN, SYN/ACK, ACK, RST, RST/ACK, FIN, FIN/ACK, PSH, PSH/ACK, Xmas (ID 3–9, 24–26)
UDP Flood	UDP Flood (ID 11)
GRE / DNS / DHCP	GRE Flood (28), DNS Flood (109); DHCP Flood is legacy
ICMP / Amplification / Fragmentation	ICMP Flood (103), ICMP Fragmentation (104), Ping (105), Ping of Death (106), DNS Amplification (107), UDP Fragmentation (108), NTP Amplification (110)
MHDDoS Emulation	Combined plugin (ID 23) with SYN/UDP/GRE/STRESS/BYPASS/HTTP TEMPLATE and other subplugins

Related but separate scenarios: WAF, including HTTP/2 Rapid Reset, and Fuzzing (L3–L7).

ICMP, Ping, Amplification, and Fragmentation

ICMP Flood

ICMP Flood generates a stream of ICMP packets with configurable type/code and payload size. Use it to test ICMP processing, filtering, and resilience against L3 floods. This is a client-side (one-arm) plugin: the source is the Peresvet ST agent, and the target is the DUT or service.

Name	Description	Value
Type	ICMP type	0–255 (default: 8)
Code	ICMP code	0–255 (default: 0)
Send payload / size	ICMP payload	Enable and specify a size or data

Packets per second	Target intensity	Numeric value or Unlimited

Dashboard: ddos_icmp_flood.

ICMP Fragmentation Flood

Sends ICMP Echo Requests as sequences of IPv4 fragments with correct offset/MF/ip_id values. Use it to test the reassembly path and fragmented-ICMP processing. This is a client-side one-arm plugin; its common tabs are the same as for ICMP Flood (sources, targets, L3, payload, PPS, and duration).

Dashboard: ddos_icmp_fragmentation.

Ping Flood

Generates a high-volume stream of ICMP Echo Requests with type=8 / code=0 and a configurable payload. Unlike ICMP Flood, type/code are fixed to Echo Request. This is a client-side one-arm plugin.

Dashboard: ddos_ping_flood.

Ping of Death Flood

Generates oversized ICMP Echo Requests through IPv4 fragments with Ping of Death reassembly semantics. Use it only in an isolated test environment: the purpose is to verify DUT stack resilience, not to disrupt a production system. This is a client-side one-arm plugin.

Dashboard: ddos_ping_of_death.

DNS Amplification (UDP)

Generates amplification-oriented UDP/53 DNS queries: an ANY IN question with an EDNS0 OPT record and an increased UDP buffer size. This profile does not use spoofing or external reflectors: the source is the agent, and the target is a DUT or resolver in the test environment.

Name	Description	Value
Recursion Desired (RD)	RD flag	Enable/disable
Random domains	Random name in each query	Enable/disable
Domains	Fixed list of names	Used when Random domains is disabled
Queries per second	Target intensity	Numeric value or Unlimited

Dashboard: ddos_dns_amplification. Difference from DNS Flood: amplification uses an ANY+EDNS0 profile, while DNS Flood sends ordinary queries with configurable domains.

UDP Fragmentation Flood

Sends a UDP datagram as IPv4 fragments: the first fragment contains the UDP header, while subsequent fragments use the same ip_id and correct fragment offset/MF values. This is a client-side one-arm plugin. Legacy IP Fragmentation Flood is unavailable in the current catalog.

Dashboard: ddos_udp_fragmentation.

NTP Amplification (UDP)

Generates UDP/123 NTP private-control, monlist-like requests to test an NTP amplification profile without spoofing or external reflectors. This is a client-side one-arm plugin.

Dashboard: ddos_ntp_amplification.

H2 HTTP TEMPLATE

H2 HTTP TEMPLATE is a traffic-generation subplugin that uses HTTP 2 to generate HTTP requests from a configured template and emulate legitimate or malicious traffic.

The plugin has the following parameters:
