Detecting Possible Domain Generation Algorithm-Related Threats Using Typosquatting Data Feed

Domain generation algorithm (DGA) is used to generate several domain names commonly used for command-and-control (C&C) servers in malware attacks. The logic behind a domain name generation algorithm is quite simple. Instead of hard-coding the domain or IP address into the malware, the malware finds its C&C under a domain with a seemingly random name. more
