Bypass security scripts, devices and services that attempt to mitigate DDoS attacks through the blacklisting of attacking IP addresses.Ī reflected DDoS attack uses IP spoofing to generate fake requests, ostensibly on behalf of a target, to elicit responses from under protected intermediary servers.

Prevent targets from notifying device owners about an attack in which they are unwittingly participating.Avoid discovery and implication by law enforcement and forensic cyber-investigators.shepherds), to max out their target’s resource capacity, resulting in server downtime and network saturation.īotnets are typically comprised of either random, geographically dispersed devices, or computers belonging to the same compromised network (e.g., hacked hosting platform).īy using spoofed IP addresses to mask the true identities of their botnet devices, perpetrators aim to: Such floods enable botnet operators, (a.k.a. They can be instructed to collectively access a given domain or server, providing perpetrators with the computing and networking resources to generate huge traffic floods. IP address spoofing is used for two reasons in DDoS attacks: to mask botnet device locations and to stage a reflected assault.Ī botnet is a cluster of malware-infected devices remotely controlled by perpetrators without the knowledge of their owners. IP spoofing is a default feature in most DDoS malware kits and attack scripts, making it a part of most network layer distributed denial of service DDoS attacks. IP address spoofing is the act of falsifying the content in the Source IP header, usually with randomized numbers, either to mask the sender’s identity or to launch a reflected DDoS attack, as described below. One such header is the ‘Source IP Address’, which indicates the IP address of the packet’s sender.

It’s typically used in DoS assaults.Ĭomputer networks communicate through the exchange of network data packets, each containing multiple headers used for routing and to ensure transmission continuity. IP address spoofing – Disguises an attacker’s origin IP.It’s typically used in denial of service (DoS) and man-in-the-middle assaults. ARP spoofing – Links a perpetrator’s MAC address to a legitimate IP address through spoofed ARP messages.DNS server spoofing – Modifies a DNS server in order to redirect a domain name to a different IP address.It’s often used during a cyberattack to disguise the source of attack traffic. Spoofing is an impersonation of a user, device or client on the Internet.
