What is a domain shadowing attack?

Domain shadowing basically refers to the cybercriminal exercise of infiltrating multiple domain registrant accounts in order to spew forth several subdomains for malicious purposes. Cyber criminals are able to acquire login credentials to these registrant accounts through methods like phishing and keylogging.

What is domain fluxing?

Domain fluxing is a technique for keeping a malicious botnet in operation by constantly changing the domain name of the botnet owner’s Command and Control (C&C) server. Each bot then sends out DNS queries to the random domains until one of them actually resolves to the address of the C&C server.

What kind of attack rotates the sub domains associated with a single domain every few minutes?

Domain Shadowing
Domain Shadowing rotates subdomains associated with a single domain rapidly.

What is DNS tunneling?

DNS tunneling exploits the DNS protocol to tunnel malware and other data through a client-server model. A connection is now established between the victim and the attacker through the DNS resolver. This tunnel can be used to exfiltrate data or for other malicious purposes.

How do I stop flux fast?

How can DNS fast fluxing be prevented? The most effective way to stop DNS fast fluxing is to simply take down the domain name. For a variety of reasons, domain name registrars are not always willing or able to do so.

What is botnet in cyber security?

A botnet (short for “robot network”) is a network of computers infected by malware that are under the control of a single attacking party, known as the “bot-herder.” Each individual machine under the control of the bot-herder is known as a bot. They are also used to spread bots to recruit more computers to the botnet.

Can you get hacked through DNS?

A DNS may be hacked for a range of reasons. The hijacker may use it for pharming, which is to display ads to users to generate revenue or phishing, which is directing users to a fake version of your website with the aim of stealing data or login information.

What is phantom domain attack?

A phantom domain attack happens when the attacker sets up “phantom” domains that do not respond to DNS queries. When phantom domain attacks happen, the recursive server continues to query non-responsive servers, which causes the recursive server to spend valuable resources waiting for responses.

What is DNS Zonewalk?

A DNS zone walking attack attempts to get all content from DNSSEC-signed DNS zones. If Route 53 Resolver team detects a traffic pattern that matches the ones generated when DNS zones are walked on your endpoint, the service team will throttle the traffic on your endpoint.

What is TCP over DNS?

tcp-over-dns contains a special dns server and a special dns client. The client and server work in tandem to provide a TCP (and now UDP too!) tunnel through the standard DNS protocol. tcp-over-dns was written to be quite robust while at the same time providing acceptable bandwidth speeds.

Is Flux a malware?

Malware flux is a relatively simple procedure which basically “hides” the malware in two waves of Trojans. As many of you may know, Trojans aren’t necessarily stopped by cybersecurity architectures, but mainly just isolated until the internal clocking engine associates them with other particular threats.

What is double flux?

A more sophisticated type of fast flux, referred to itself as “double-flux”, is characterized by multiple nodes within the network registering and de-registering their addresses as part of the DNS Name Server record list for the DNS zone.
