A Domain Generation Algorithm (DGA) is a technique used by cyber attackers to generate new domain names and IP addresses for malware's command and control servers. Executed in a manner that seems random, it makes it nearly impossible for threat hunters to detect and contain the attack.4 Jun 2021
How are domains generated?
Domain Generating Algorithms are in use by cyber criminals to prevent their servers from being blacklisted or taken down. The algorithm produces random looking domain names. The idea is that two machines using the same algorithm will contact the same domain at a given time.6 Dec 2016
How do you prevent DGA?
Because DGA is a technique the fuels malware attacks, the things you can do to help prevent malware can also help prevent DGA-fueled malware attacks: Don't open attachments that are unexpected or from unknown sources.7 Feb 2019
What is DGA monitoring?
Dissolved gas analysis (DGA) is an examination of electrical transformer oil contaminants. Insulating materials within electrical equipment liberate gases as they slowly break down over time. Online monitoring of electrical equipment is an integral part of the smart grid.
What is online DGA?
Online DGA (Dissolved Gas Analysis) for transformers is a reasonable safety tool. Analysis of the gases solved in transformer oil has become a common instrument for early detection and diagnosis of transformer malfunctions.
What is DGA of transformer oil?
Dissolved gas analysis (DGA) is an examination of electrical transformer oil contaminants. Insulating materials within electrical equipment liberate gases as they slowly break down over time.
What is the purpose of dissolved gas analysis in transformers?
Dissolved gas analysis (DGA) of transformers can provide insights into thermal and electrical stresses sustained by oil-immersed power transformers. Because it detects incipient transformer faults, DGA can help prevent further damage.
How do I protect against DGA?
Another way to disrupt a known DGA-based malware is to register the generated domains, which serves to both prevent the attackers from registering the domains and also detect already-infected machines that communicate with these domains.
