The IP address has been identified as associated with the Asprox botnet, also known by its aliases Badsrc and Aseljo, and is mostly involved in phishing scams and performing SQL injections into websites in order to spread malware
The IP address has been identified as being associated with a Command-and-control (C2) Server. Command-and-control servers are used by attackers to maintain communications with compromised endpoints within a targeted network. These compromised endpoints collectively are referred to as a botnet. This is achieved through infecting endpoints with malware. Botnets are leveraged by attackers to conduct malicious activity (send spam, distribute malware, etc) without the knowledge of the system owner.
This data was discovered in a hidden Dark Web internet relay chatroom (IRC).
The IP address has been identified as associated with the Cutwail botnet and is mostly involved in sending spam e-mails. The bot is typically installed on infected machines by a Trojan component called Pushdo. It affects computers running Microsoft Windows.
The IP address has been identified as associated with malicious file sharing activities.
