According to the latest report from the Phishtank, a great resource for OSINT data, five IPs were hosting 6547 phishing campaigns in April, all of which are courtesy of the Asprox botnet, a botnet that despite being actively sending phishing emails for the last couple of months, received more publicity for its introduction of SQL injection capabilities, like the ones I've assessed in a previous post. The IPs in question :212.174.25.241
62.233.145.45
218.92.205.246
85.105.182.6
212.0.85.6
Where's the connection? It's in the historical domains that used to respond to the IPs, in the Asprox case, a great deal of the original domain names used a couple of months ago are still in a fast-flux and further expose and connection between these IPs and Asprox. For instance, 62.233.145.45, is known to have been hosting xml52.com; www5.yahoo.american-greeting.ca.xml52.com; yahoo.americangreeting.ca.www05.net; bendigobank.com.au.tampost5.ws; among the domains used in some of the previous phishing domains. The rest of the IPs are also known to have participated in the fast-flux, and therefore, as long as they remain using some of their old domains, and fast-flux them in a way that can be compared to the data from previous months, monitoring the prevalence of Asprox phishing campaigns and making the connection between a phishing campaign and the botnet, would remain easy to do.
