+{"id":452,"text":"One of the most important “innovations” in malware in the past decade is what’s called a Domain Generation Algorithm (“DGA”)”.","entities":[],"relations":[],"Comments":[]}
+{"id":453,"text":"DGA is an automation technique that attackers use to make it harder for defenders to protect against attacks.","entities":[],"relations":[],"Comments":[]}
+{"id":454,"text":"While DGA has been in use for over 10 years now, it’s still a potent technique that has been a particular challenge for defenders to counter.","entities":[],"relations":[],"Comments":[]}
+{"id":455,"text":"Fortunately, there are emerging technologies now that can better counter DGAs.","entities":[],"relations":[],"Comments":[]}
+{"id":456,"text":" What is it?","entities":[],"relations":[],"Comments":[]}
+{"id":457,"text":" A Domain Generation Algorithm is a program that is designed to generate domain names in a particular fashion.","entities":[],"relations":[],"Comments":[]}
+{"id":458,"text":"Attackers developed DGAs so that malware can quickly generate a list of domains that it can use for the sites that give it instructions and receive information from the malware (usually referred to as “command and control” or C2).","entities":[],"relations":[],"Comments":[]}
+{"id":459,"text":" Attackers use DGA so that they can quickly switch the domains that they’re using for the malware attacks.","entities":[],"relations":[],"Comments":[]}
+{"id":460,"text":"Attackers do this because security software and vendors act quickly to block and take down malicious domains that malware uses.","entities":[],"relations":[],"Comments":[]}
+{"id":461,"text":"Attackers developed DGA specifically to counter these actions.","entities":[],"relations":[],"Comments":[]}
+{"id":462,"text":" In the past, attackers would maintain a static list of malicious domains; defenders could easily take that list and start blocking and taking down those sites.","entities":[],"relations":[],"Comments":[]}
+{"id":463,"text":"By using an algorithm to build the list of domains, the attackers also make it harder for defenders to know or predict what domains will be used than if they had a simple list of domains.","entities":[],"relations":[],"Comments":[]}
+{"id":464,"text":"To get that list of domains that the malware will use, defenders have to decode the algorithm which can be difficult.","entities":[],"relations":[],"Comments":[]}
+{"id":465,"text":" Even then, taking down sites that malware using a DGA can be a challenge as defenders have to go through the process of working with ISPs to take down these malicious domains one by one.","entities":[{"id":46124,"label":"identity","start_offset":134,"end_offset":137}],"relations":[],"Comments":[]}
+{"id":466,"text":"Many DGAs are built to use hundreds or even thousands of domains.","entities":[],"relations":[],"Comments":[]}
+{"id":467,"text":"And these domains are often up for only limited periods of time.","entities":[],"relations":[],"Comments":[]}
+{"id":468,"text":"In this environment blocking and taking down DGA-related domains quickly becomes a game of “whack a mole” that is sometimes futile.","entities":[],"relations":[],"Comments":[]}
+{"id":469,"text":" Why should I care, what can it do to me?","entities":[],"relations":[],"Comments":[]}
+{"id":470,"text":" DGA by itself can’t harm you.","entities":[],"relations":[],"Comments":[]}
