Domain Generation Algorithm Network Evasion

Domain generation algorithms (DGAs) are algorithms used by malware to generate a large number of domain names that can be used as communication channels with their command and control servers. These domain names are generated periodically, typically using a pseudorandom number generator.

The use of DGAs makes it difficult for law enforcement and other security actors to shut down botnets, …

Homograph Attack (Punycode) Network Evasion

A homograph attack is a type of phishing attack that uses homoglyphs (characters that look similar to other characters) to create domain names or URLs that appear to be legitimate, but are actually controlled by an attacker. Homograph attacks take advantage of the fact that many languages have characters that are visually similar to characters used in other languages.

DNS Hijacking Network Evasion

DNS hijacking or DNS redirection is a technique used to subvert the normal domain name resolution process. It involves redirecting DNS queries to a rogue DNS server controlled by an attacker, or modifying the behavior of a trusted DNS server so that it does not comply with internet standards. This can be done for various purposes, such as phishing attacks, …

DNS Tunneling Defense Evasion [Mitre] Network Evasion

DNS tunneling is a technique that uses the Domain Name System (DNS) protocol to transfer data in an encrypted and covert manner. It involves encoding the data of other programs or protocols in DNS queries and responses, and using DNS servers as a means of communication.

To carry out DNS tunneling, the attacker typically needs access to a compromised system …

Domain Fronting Defense Evasion [Mitre] Network Evasion

Domain fronting is a technique used to hide the true destination of internet traffic. It may be used to hide the real destination of an offensive payload or is could be used to bypass censorship or any form of network restriction. The technique may be used through CDN infrastructure or on any infrastructure that perform separation between SSL and http …

DNS API Injection Process Manipulating

DNS API injection is a technique used by malware to evade detection by intercepting and modifying DNS (Domain Name System) requests made by a host system. The technique involves injecting code into the DNS API (Application Programming Interface) of the host system, which is a set of functions and protocols that allow communication with the DNS service. By injecting code …

Domain Member Sandbox Evasion

This technique determines if a host is a member of an Active Directory Domain without API calls. It helps prevent malicious payload execution in enterprise sandboxes that are not members of an Active Directory domain. The validation is done by checking the "LoggonServer" and "ComputerName" environment variables. If the host is logged into a domain controller, the "LoggonServer" value will …

Domain Policy Modification: Domain Trust Modification Defense Evasion [Mitre]

Adversaries may add new domain trusts or modify the properties of existing domain trusts to evade defenses and/or elevate privileges. Domain trust details, such as whether or not a domain is federated, allow authentication and authorization properties to apply between domains for the purpose of accessing shared resources. These trust objects may include accounts, credentials, and other authentication material applied …
